The accompanying drawing explanation
Below the content of every width accompanying drawing expression in specification of the present invention and the mark in figure are briefly described:
Fig. 1 is that the measure and control device remote signalling of a kind of electric substation measures the test system structured flowchart.
Embodiment
Known referring to Fig. 1, full station synchro system unified time that this system is based on electric substation's installation is the satellite time transfer device, this device reception Beidou satellite navigation system or gps satellite are as the external time reference signal, hereinafter take GPS as example explanation, gps satellite synchronised clock can realize entirely the standing operation monitoring of each system under the unified time benchmark and the accident analysis after accident.Electric substation is provided with a large amount of automation equipments, these equipment comprise measure and control device, fault oscillograph, microcomputer protecting device, the station level main frame, remote control communication equipment etc., the precision clock synchronizing signal that the output of satellite time transfer device is provided by GPS is to all automation equipments of electric substation, unified electric substation, the time reference of control centre, after electric power system is broken down, improved 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 has been created good technical conditions.Existing gps satellite clock system support firmly to the time (impulse contact 1PPS etc.), soft to the time (serial ports message), coding to the time (IRIG-B, DCF77) and network N TP to the time, meet domestic and international distinct device to the time interface requirement.
Some road 1PPD idle contact (pulse duration 1S by the output of a plurality of days pulse units (1PPD) of Substation Time Synchronous System, sending of day pulse 1PPD can be set constantly) signal, receive the stand-by state amount input terminal of every measure and control device in station by the general control cable, at the sky pulse action arranged constantly, within all days, the pulse idle contact all will produce a displacement signal, make each measure and control device that receives this signal produce respectively a SOE displacement information, and on deliver to this computer supervisory control system and by remote control communication equipment the upper level system to electric substation outside export, relatively 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, be used for measure and control device, electric substation's computer supervisory control system and upper level system thereof are carried out the test of remote signalling action accuracy, the test of system remote signalling response time, remote signalling displacement test, the test of telemetry system time accuracy, the SOE instation test, test between the SOE station, the excessive remote signalling displacement of system disposal ability (remote signalling storm) test.Wherein the upper level automated system comprises Masterstation Automation System and power network schedule automation main station system.
Concrete method of testing is as follows:
The test of remote signalling action accuracy:
The not high main cause of current remote signalling action accuracy is the shake, electromagnetic interference, the loose contact of remote signalling loop, passage error code of switch auxiliary contact or relay etc.Because the link that causes malfunction and fail to report is numerous, the remote signalling enormous amount, search difficult.And the malfunction of circuit breaker and disconnecting link position and important guard signal and fail to report and cause serious interference by power grid accident is processed, and will produce 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, here supposition has 50 measure and control devices and has respectively accessed sky, a road pulse idle contact signal, at the sky pulse action arranged constantly, these measure and control devices have all produced one and have taken turns action and return after pulse in SOE(days is arranged in action 1S and return), should send altogether 100 SOE signals, according to this electric substation's computer supervisory control system and upper level system thereof receive this action and return the SOE signal the number (containing tripping and malfunction), just can calculate respectively in said system the remote signalling action accuracy in the 1S time interval belonged in this electric substation's scope.
If this electric substation's computer supervisory control system remote signalling action accuracy is high, and its upper level system accuracy is low, illustrates that may there be the error code phenomenon in electric substation toward the teletransmission passage of upper level system, but emphasis solves the channel quality problem.If leak to send out a day pulse signal and cause remote signalling action accuracy to descend due to the minority measure and control device, it may be the remote signalling power work abnormal (short circuit or broken string) of these devices or measure and control device and the fault or unstable of having communicated by letter of station level system.In a word, the mistake existed according to each system is posted a letter or is failed to report the comparisons such as the number of number of times and abnormal device occurrence number, can very fast delineation abnormality scope, thus fix a breakdown targetedly.
The test of system remote signalling response time:
Because moment of sky pulse action is known fixed time, be equivalent to carve at this moment the on-the-spot remote signalling action event that occurs of measure and control device, we can start the stopwatch counting in this known moment, statistics electric substation computer supervisory control system, Masterstation Automation System or power network schedule automation main station system picture disply to or detect this and move the required response time and whether meet specifically applicable rules requirement.
The time accuracy test:
Because moment of sky pulse action is known fixed time, each measure and control device all will produce respectively a SOE displacement information after receiving day pulse action information, and stamp timestamp separately, this electric substation's computer supervisory control system and upper level system thereof also all can be stamped mark operate time according to the system time of oneself after receiving these remote signalling displacement information, therefore by check concrete SOE displacement information can judge corresponding measure and control device to the time precision, can verify this electric substation's computer supervisory control system and each own time accuracy of upper level system thereof according to the remote signalling displacement information corresponding with certain SOE displacement information.For instance, the moment of supposing first electric substation sky pulse action is set as 16: 0: 0 of every day, the sky pulse SOE displacement information of sending on regional power grid scheduling automation main website system is received first electric substation No. 1, No. 2 etc. measure and control device is all 000 millisecond of 16: 0: 0 on the 1st October (date information is omitted in following discussion) in 2011, illustrate first electric substation measure and control device accept clock synchronization system to the time normal; If it is 998 milliseconds of 16: 0: 0 001 millisecond or 15: 59: 59 that the sky pulse SOE displacement information of sending on the part measure and control device is arranged, explanation have the part measure and control device to the time have a fast or partially slow phenomenon; If the sky pulse SOE displacement information of sending on a lot of or whole measure and control devices be not 16: 0: 0 000 millisecond, need the operation such as electric substation's review time synchro system signal source, day pulse unit or whether normally arrange.If the scheduling station system is when receiving above-mentioned 16 o'clock 0 minute 0 second SOE of 000 millisecond, the remote signalling displacement time of its record is 16: 0: 5 or 15: 59: 54, and the test of main station system remote signalling response time meets the quantity of state displacement and is transferred to main station time≤3s, illustrating that main station system is punctual exists fast or partially slow phenomenon, corrective system time in time.
Remote signalling displacement test:
In current automation system for the power network dispatching at different levels still ubiquity remote signalling wrong report and fail to report phenomenon, being the shown remote signalling state of all kinds of remote ports of dispatch automated system (electric substation's computer supervisory control system, Masterstation Automation System, scheduling station system) does not conform to or leaks activating alarm information with the source signal state of electric substation reality, the dispatch automated system confidence level is descended, be unfavorable for that the administration of power networks personnel grasp the operation of power networks situation in real time, the correct judgement of impact 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 rules also require preferential transmission.The on-the-spot rules of the electric substation's telemechanical also main contents of regulation tour telecontrol equipment should comprise inspection remote signalling state, do in case of necessity positioning test.The link whether the remote signalling displacement normally involves is more, for instance, on-the-spot certain breaker operator displacement, the main website remote signalling is really reactionless, and main cause may have:
(1) lose during the main website process information;
(2) because of channel failure, lose;
(3) measure and control device or telemechanical master control plant failure, the remote signalling unreacted;
(4) loose contact of switch auxiliary contact or relay do not move.
This test macro can every day timing automatic the measure and control devices of electric substation's all accesses day pulse idle contact are produced to one-off and involution remote signalling displacements, be equivalent to every day the remote signaling function of measure and control device be done to once health check-up comprehensively, record remote signalling displacement information by verifying on-the-spot remote signalling displacement roll-call action character and a distant place, receive sequence of events recording SOE tripartite consistency, investigate the measure and control device unimpeded accuracy of communicating by letter with distant place automated system, find in time said apparatus and system and the configuration of main factory station data storehouse point table, the telecontrol channel tissue, communication protocol, the weak link of traffic rate, carry out targetedly malfunction elimination and rectification, improve work quality and efficiency.
The SOE instation test:
The SOE event is a kind of input of the switching value with synchronized timestamp displacement event, and the SOE module not only will gather the state of remote signalling displacement, the moment of also wanting the displacement of synchronous recording remote signalling state to occur.In substation automation system, sequence of events recording-SOE(Sequence of Events) critical function is exactly the sequencing that in the time of will correctly distinguishing electric network fault, all kinds of events occur, for correctly processing accident of dispatching of power netwoks operations staff, analysis and judgement electric network fault provide important means.Thereby, in electrical network SOE correctly record extremely important.
Access electric substation many measure and control device quantity of states are opened the sky pulse action displacement simultaneously constantly that the sky pulse idle contact into terminal is arranging, a plurality of remote signalling action event that are equivalent to simulated field, whether test electric substation's computer supervisory control system and upper level system thereof can correctly identify two and above remote signalling action event in same electric substation.
Test between the SOE station:
By first, synchronization all is arranged in the action of second electric substation sky pulse constantly, or the sky pulse action of first electric substation is arranged to integral point constantly constantly, pulse (1PPH when existing with second electric substation, pulse duration 1S) actuating signal compares, test the first and second two same upper level systems that electric substation belongs to and whether can correctly identify two and above action event in different electric substations, and the precedence of the different SOE of the electric substation information arrival that receive, the communication protocol of the first and second two electric substations and upper level automated system relatively accordingly, traffic rate, communication mode and processing response time quality.
The test of remote signalling storm:
According to standby of concrete measure and control device remote signalling unit, scene quantity, every 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, thereby test 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.
General electric substation measure and control device is all two specifically, more than 30, some 500kV electric substation even can reach nearly 60, if 55 measure and control devices of first electric substation are access 1 sky, road pulse idle contact signal all, first electric substation returns constantly and all will export a large amount of remote signalling displacements in the 1S interval altogether with action at the sky pulse action, add up 110 remote signalling displacements, if gps clock signal extension device sky pulse unit quantity is enough, give all access 2 sky, road pulse idle contact signals of every measure and control device, the remote signalling displacement will expand to 220, can test 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 fully.
In sum, native system and method for testing thereof have following characteristics:
