Technical field
The present invention relates to the grid simulation technology, particularly relate to a kind of technology that realizes the static Simulation mode of the real-time SOE under the electric network fault situation.
Background technology
Dispatcher's training simulation system (Dispatcher Training Simulator, DTS) adopt The present computer technology, the algorithm that utilization is ripe, by setting up the mathematical model of practical power systems, simulation scheduler routine personnel to the operation of various device and fault after to the processing of various situations, and can be normal at electrical network, system call person is giveed training under the accident, recovery control, train their normal consistency ability and the high-speed decision ability during accident, improve yardman's the operation level and the technical ability of analyzing and processing fault.
Under normal running and misoperation mode, sequence of events recording (Sequence Of Event, SOE) system is the incident of the up main website of substation secondary device, the operating condition of reaction electrical network primary equipment, the type of the Time And Event that record trouble takes place, XX divides the fault that what type takes place XX XX second millisecond during such as certain switch XX, for SOE, in order to tell the priority of each signal of interest accurately, the SOE record must reach 1ms even littler resolution.Often use SOE to write down a succession of action event of a certain moment generation in the electric system.
Owing to the time that abnormal conditions occur is generally very short, about several milliseconds were difficult to catch this variation by several seconds from real-time telemetry, and what the triggering mode of employing SOE can be complete notes abnormal conditions, uses for the steady-state analysis software emulation.
Present simulation software generally manually is provided with electric network fault based on the yardman, adopts analysis software module analog computation trend to distribute, and this result is offered the dispatcher analyze, make a strategic decision, to promote yardman's analysis decision ability.
But this fault based on artificial setting; often be subjected to influences such as yardman's initiative, personal knowledge face; emulation is come in the guard signal, the microcomputer simulation signal aspect that are difficult to from substation secondary device; the scope of emulation is confined to the electric network swim running status of main website side, causes the imperfection of emulation.
Summary of the invention
At the defective that exists in the above-mentioned prior art, technical matters to be solved by this invention provides the method based on the electrical network static Simulation mode of SOE; Can guarantee that data of database is irredundant, and can guarantee the data storage of Millisecond, guarantee to form the authenticity and integrity of teaching notes in the unusual period.
In order to solve the problems of the technologies described above, the method for the electrical network static Simulation mode based on SOE provided by the present invention, it is characterized in that: concrete steps are as follows:
1) sets up the real time data database in main website of control center side, set up data table memory DataTable with storage transformer station upstream data;
2) set up electrical network teaching notes emulation concordance list TrainingTable, use this to show to write down simulated events;
3) the up data of transformer station are divided into real time data RealData and event data EventData, real time data comprises real-time telemetry Realanalog, the real-time real-time Realdigtal of remote signalling, variety of event data RealSOE;

RealDataGroup＝{Realanalog，Realdigtal，RealSOE}；
EventDataGroup＝{Realanalog，Realdigtal，RealSOE，Eventanalog，Eventdigtal，EventSOE}；
4) definition electrical network stable state needs the event type Eventtype of emulation, and event type and SOE type (SOEtype) are shone upon, that is:
Eventtype-＞SOEtype；
It is the unusual period that definition simultaneously needs the simulated events type period to occur, and all the other are the normal period;
5) circulation receives transformer station's upstream data, if do not receive and need the SOE type handled, promptly need not normal period of storing, and do not have accident, tables of data DataTable only to handle real time data collection RealDataGroup this moment, changes step 9) over to;
6) if constantly unusual, promptly there is the accident that requires record, when perhaps requiring other incidents of record, needs processing events data set EventDataGroup this moment;
7) stipulations of using standard are such as the IEC-103 stipulations, and the data collector of transformer station is sent event data calling order, in the data storage EventDataGroup of calling, and the event description of record calling automatically and incident generation beginning and ending time;
8) the EventDataGroup data acquisition is stored among the tables of data DataTable, and start time StartTime, the concluding time EndTime of calling data are charged among the emulation teaching notes table TrainingTable, change step 10) over to;
9) the RealDataGroup data acquisition is stored among the tables of data DataTable;
10) repeating step 5) the circular treatment real time data.
The beneficial effect of the method for the electrical network static Simulation mode based on SOE provided by the invention: based on real-time SOE, according to the type of emulation, be mapped on the SOE earlier, when detecting the unusual period that needs record, storage needs the event data of record.The actual response substation secondary device; Teaching notes need not artificial making: because SOE is real-time, and the up abnormal data of transformer station can mend and call together, when abnormal data occurring, can call all data of needs again the data center of main website, the teaching notes of this incident as emulation like this.Be the data dividing time-steps the normal and unusual period simultaneously, corresponding data is divided into real time data and event data, guarantees that data of database is irredundant, and can guarantee the data storage of Millisecond, the authenticity and integrity of assurance formation teaching notes in the unusual period.
