Accompanying drawing explanation
Mark in the content expressed every width accompanying drawing in specification of the present invention below and figure is briefly described:
Fig. 1 is that the measure and control device remote signalling of a kind of electric substation measures test system structured flowchart.
Embodiment
Known see Fig. 1, this system be based on electric substation install full station synchro system unified time and satellite time transfer device, this device reception Beidou satellite navigation system or gps satellite are as external time reference signal, hereafter illustrate for GPS, gps satellite synchronised clock can realize entirely standing the operation monitoring of each system under uniform time reference and the accident analysis after accident.Electric substation is provided with a large amount of automation equipment, these equipment comprise measure and control device, fault oscillograph, microcomputer protecting device, station level main frame, remote control communication equipment etc., satellite time transfer device exports the Precision Clock Synchronization signal that provided by the GPS all automation equipments to electric substation, unified electric substation, the time reference of control centre, after electric power system is broken down, improve the time accuracy of SOE, for analyzing circuit breaker and protection, the sequencing of automatic safety device action provides strong evidence, for electricity net safety stable monitoring and controlling system creates good technical conditions.(impulse contact 1PPS etc.) during existing hard pair of gps satellite clock system support, soft pair time (serial ports message), coding pair time (IRIG-B, DCF77) and network N TP couple time, meet domestic and international distinct device pair time interface requirement.
By some road 1PPD idle contact (pulse duration 1S that Substation Time Synchronous System multiple days pulse unit (1PPD) exports, the moment that sends of day pulse 1PPD can set) signal, the stand-by state amount input terminal of every platform measure and control device in station is received by general control cable, the sky pulse action moment arranged, all sky pulse idle contacts are all by generation one displacement signal, make each the measure and control device receiving this signal produce a SOE respectively and conjugate information, and on deliver to this computer supervisory control system and by remote control communication equipment to outside electric substation upper level system export, more each measurement and control unit to the time difference of same event response and each receiving system to the SOE disposal ability with a collection of event, for to measure and control device, electric substation's computer supervisory control system and upper level system thereof carry out the test of remote signalling action accuracy, the system remote signalling response time tests, remote signalling displacement test, telemetry system time accuracy is tested, SOE instation test, test between SOE station, excessive remote signalling displacement disposal ability (remote signalling storm) test of system.Wherein upper level automated system comprises Masterstation Automation System and power network schedule automation main station system.
Concrete method of testing is as follows:
Remote signalling action accuracy is tested:
The main cause that current remote signalling action accuracy is not high is the shake, electromagnetic interference, the loose contact of remote signalling loop, passage error code etc. of switch auxiliary contact or relay.Due to cause malfunction and the link failed to report numerous, remote signalling enormous amount, searches not easily.And the malfunction of circuit breaker and disconnecting link position and important guard signal and fail to report and electric network accident management will be caused to serious interference, and by generation to other remote signalling action distrusts.Therefore must work harder, steadily improve remote signalling action accuracy.
The examination of remote signalling action accuracy refers to remote signalling correct operation number of times and correct operation number of times+tripping, the percentage of malfunction number of times sum, electric substation's measure and control device is N number of, here supposition has 50 measure and control devices and has respectively accessed sky, a road pulse idle contact signal, the sky pulse action moment then arranged, these measure and control devices all create one take turns action and return after pulse in SOE(days is arranged in action 1S return), 100 SOE signals should be sent altogether, according to this electric substation's computer supervisory control system and upper level system acceptance thereof to this action and the number (containing tripping and malfunction) returning SOE signal, just the remote signalling action accuracy in the 1S time interval belonged within the scope of this electric substation can be calculated in said system respectively.
If this electric substation's computer supervisory control system remote signalling action accuracy is high, and its upper level system accuracy is low, then illustrate that the teletransmission passage of electric substation's up level system may exist error code phenomenon, channel quality problem can be solved by emphasis.If cause remote signalling action accuracy to decline because minority measure and control device leaks a sky pulse signal, then may be that the remote signalling power work abnormal (short circuit or broken string) of these devices or the communication of measure and control device and station level system have fault or instability.In a word, the comparisons such as the number transmitting by mistake or fail to report number of times existed according to each system and abnormal device occurrence number, can very fast delineation abnormality scope, thus fixes a breakdown targetedly.
The system remote signalling response time tests:
Moment because of sky pulse action is known fixed time, be equivalent to carve measure and control device scene at this moment and remote signalling action event occurs, we can start stopwatch counting in this known moment, and statistics electric substation computer supervisory control system, Masterstation Automation System or power network schedule automation main station system picture are shown to or detect whether the response time needed for this action meets the concrete regulatory requirements be suitable for.
Time accuracy is tested:
Moment because of sky pulse action is known fixed time, each measure and control device all conjugates information by producing a SOE respectively after receiving day pulse action information, and stamp respective timestamp, this electric substation's computer supervisory control system and upper level system thereof also all can stamp mark operate time according to the system time of oneself after receiving these remote signalling displacement information, therefore by checking that concrete SOE conjugates precision when information can judge corresponding measure and control device pair, conjugate information can verify this electric substation's computer supervisory control system and each own time accuracy of upper level system thereof according to conjugating remote signalling corresponding to information with certain SOE.For example, assuming that when the moment of first electric substation sky pulse action is set as 16 of every day 0 point 0 second, when regional power grid scheduling automation main station system receives the sky pulse SOE that No. 1, first electric substation, the measure and control devices such as No. 2 send to conjugate information be all 1 day 16 October in 2011 0 point 0 second 000 millisecond (following discussion omits date information), then illustrate that first electric substation measure and control device is normal when accepting clock synchronization system pair; When if to have sky pulse SOE that part measure and control device send to conjugate information be 16 0 point 0 second 001 millisecond or 15 time 59 points 59 seconds 998 milliseconds, then illustrate to have during part measure and control device pair to there is fast or partially slow phenomenon; If sky pulse SOE that a lot of or whole measure and control device send conjugates information when not being 16 0 point 0 second 000 millisecond, then need electric substation's review time synchro system signal source, sky pulse unit etc. to run or whether normally arrange.If scheduling station system is when receiving above-mentioned 16 during 0 point of 0 second SOE of 000 millisecond, remote signalling displacement time of its record when being 16 0 point 5 seconds or 15 time 59 points 54 seconds, and the main station system remote signalling response time test meet quantity of state displacement be transferred to main station time≤3s, then illustrate that main station system is punctual and there is fast or partially slow phenomenon, should corrective system time in time.
Remote signalling displacement test:
In current automation system for the power network dispatching at different levels, still ubiquity mal-telecommunic ation and is failed to report phenomenon, namely the remote signalling state shown by all kinds of remote port of dispatch automated system (electric substation's computer supervisory control system, Masterstation Automation System, scheduling station system) does not conform to the source signal state of electric substation's reality or leaks activating alarm information, dispatch automated system confidence level is declined, be unfavorable for that administration of power networks personnel grasp grid operating conditions in real time, affect the correct judgement to power grid accident and abnormal conditions.Therefore in dispatch automated system, remote signalling is a vital ring in " four is distant ", and especially remote signalling displacement power network schedule automation code also requires preferential transmission.The on-the-spot code of the electric substation telemechanical main contents that also regulation makes an inspection tour telecontrol equipment should comprise and check remote signalling state, do positioning test if desired.It is more that remote signalling conjugates the link whether normally involved, for example, on-the-spot certain breaker operator displacement, main website remote signalling is really reactionless, and main cause may have:
(1) lose during main website process information;
(2) lose because of channel failure;
(3) measure and control device or telemechanical master control plant failure, remote signalling unreacted;
(4) loose contact of switch auxiliary contact or relay not operating.
This test macro can every day timing automatic one-off and involution remote signalling displacement are produced to the measure and control device of electric substation's all access sky pulses idle contact, be equivalent to the remote signaling function of every day to measure and control device and do once comprehensively health check-up, by verifying on-the-spot remote signalling displacement roll-call action character and a distant place is recorded remote signalling and conjugated information, receive sequence of events recording SOE tripartite consistency, investigate measure and control device to communicate with distant place automated system unimpeded accuracy, Timeliness coverage said apparatus and system and the configuration of main factory station data storehouse point table, telecontrol channel tissue, communication protocol, the weak link of traffic rate, carry out malfunction elimination and rectification targetedly, improve work quality and efficiency.
SOE instation test:
SOE event is a kind of On-off signal displacement event with synchronized timestamp, and namely SOE module not only will gather the state of remote signalling displacement, also wants synchronous recording remote signalling state to conjugate the moment occurred.In substation automation system, sequence of events recording-SOE(SequenceofEvents) critical function be exactly the sequencing that when correctly will distinguish electric network fault, all kinds of event occurs, for the correct accident settlement of dispatching of power netwoks operations staff, analysis and judgement electric network fault provide important means.Thus, in electrical network SOE correctly record extremely important.
The sky pulse action moment that pulse idle contact in sky is being arranged that access electric substation multiple stage measure and control device quantity of state is opened into terminal conjugates simultaneously, be equivalent to multiple remote signalling action event of simulated field, whether test electric substation's computer supervisory control system and upper level system thereof correctly can identify two and above remote signalling action event in same electric substation.
Test between SOE station:
By first, the action moment of second electric substation sky pulse is all arranged to synchronization, or the sky pulse action moment of first electric substation is arranged to the integral point moment, pulse (1PPH time existing with second electric substation, pulse duration 1S) actuating signal compares, whether the same upper level system of testing belonging to the first and second Liang Ge electric substations correctly can identify two and above action event in different electric substation, and the precedence that the different electric substation SOE information received arrive, compare the communication protocol of the first and second Liang Ge electric substations and upper level automated system accordingly, traffic rate, communication mode and processing response time quality.
Remote signalling storm is tested:
According to scene concrete measure and control device remote signal unit for subsequent use quantity, every platform measure and control device accesses a road or sky, some roads pulse signal intake, the total remote signalling amount of day pulse is expanded to meet the quantity of remote signalling storm test, thus test tested electric substation computer supervisory control system and upper level system thereof to the disposal ability of a large amount of remote signalling displacement in scene event.
General electric substation measure and control device is all two specifically, more than 30, some 500kV electric substations even can reach nearly 60, if first electric substation 55 measure and control devices all access 1 sky, road pulse idle contact signal, Ze Jia electric substation returns in moment common 1S interval at sky pulse action and action all will export a large amount of remote signalling displacements, add up 110 remote signalling displacements, if GPS clock signal expanding unit sky pulse unit quantity is enough, 2 sky, road pulse idle contact signals are all accessed to every platform measure and control device, then remote signalling displacement will expand to 220, tested electric substation computer supervisory control system and upper level system thereof the disposal ability to a large amount of remote signalling displacement in scene event can be tested completely.
In sum, native system and method for testing thereof have following characteristics:
Low cost: this test macro is based on dispatching automation of electric power systems present situation, current each Comprehensive Automation Substation is all equipped with a set of satellite clock signal receiving system having enough fan-out capabilities, usually shielded by one or more surfaces clock apparatus and form, master clock device receiving element receives Coordinated Universal Time(UTC) (UTC) signal of satellite transmission as external time reference signal, provides time reference signal to clock signal expanding unit simultaneously.One or more signal extension case configurable as required in clock synchronization system each clock screen, signal extension case provides multiplex pulse signal (1PPS, 1PPM, 1PPH, 1PPD idle contact, difference, TTL etc.), IRIG-B signal, DCF77 signal, time message, NTP network time signal, can meet distinct device in electric substation pair time interface requirement, when the quantity of signal extension case and output signal interface type indoor pair little of each function equipment concrete condition and determine.
Some roads 1PPD idle contact (pulse duration 1S) signal that this test macro exports Substation Time Synchronous System multiple days pulse unit (1PPD) receives the stand-by state amount input terminal of every platform measure and control device in station by general control cable, this control cables can discharge separately or utilize the core access for subsequent use of existing same paths cable.In addition, native system does not need other to drop into, and construction cost is low.
Normalization: timing every day of this test macro produces one-off and involution remote signalling displacement to the measure and control device of electric substation's all access sky pulses idle contact automatically in the moment of setting, be equivalent to the remote signaling function of every day to measure and control device and do once comprehensively health check-up, dispatching automation operator on duty in the sky pulse action moment or can verify on-the-spot remote signalling displacement roll-call action character by historical record and a distant place is recorded remote signalling and conjugated information, receive sequence of events recording SOE tripartite's content and quantitative consistency, not to upper when can find measure and control device pair in time as early as possible, remote signalling power loss, mal-telecommunic ation and failing to report, remote control communication equipment uploads the fault that Masterstation Automation System or the entanglement of scheduling station system database part point table configuration sequence etc. are not easily discovered.
Automation: this test macro every talent frequency automatically produces the measure and control device of electric substation's all access sky pulses idle contact and once concentrates action and involution remote signalling displacement, if the electric substation implemented by this system pattern is more, these electric substations can be arranged to the different sky pulse action moment, therefore bring excessive interference and increase added burden to each link of dispatch automated system, test process starts automation, do not need manual intervention, dispatching automation personnel can according to concrete test event, relevant to prepare or by regarding system historical record is carried out before the sky pulse action moment, to measure and control device, electric substation's computer supervisory control system and upper level system (Masterstation Automation System or power network schedule automation main station system) thereof carry out index of correlation, functional test and statistics.
