The demand to test equipment is tested, helps to expand the popularization and application of network prepared auto restart.
Description of the drawings
The following further describes the present invention with reference to the drawings.
Fig. 1 is the flow diagram of the present invention；
Fig. 2 is somewhere power grid statements based on collusion part-structure figure.
Specific implementation mode
Test method and flow are discussed with reference to Fig. 1, Fig. 2.Fig. 2 is somewhere power grid statements based on collusion part-structure figure, wherein
Black square indicates to close the switch of position；White square indicates the switch for dividing position.
As shown in Figure 1, a kind of network prepared auto restart control strategy automatic test approach, this method include：
(1) forecast failure process model building：Simulation model is generated according to the fault coverage of anticipation, after simulation model includes failure
The signal of given relative time is sent out, remote signalling caused by protection act conjugates situation.And telemetering changes, stands caused by interior prepared auto restart
Remote signalling is conjugated is simulated by the simulation software of scheduling controlling main website, is not included in simulation model.
The generation step of simulation model is as follows in step (1)：
1) previously given forecast failure range, 110kV busbares, the circuit usually acted in collusion to make each other's confessions on path.
2) it is directed to each specific forecast failure equipment, it is assumed that main protection signal associated there triggering, connection are opened
Tripping is closed, analogue simulation sequence is formed with this.
With reference to the accompanying drawings 2, generate following emulation testing table：
(2) mass forecast failure process simulation：It is executed according to relevant simulation model for each forecast failure
The emulation of certain time.During analogue simulation, can simulated accident separating brake, protection act, stand in prepared auto restart action or tripping, small
The functions such as power supply isolated power grid or collapse.The control instruction of also acceptable network prepared auto restart, realizes simulation division in simulation process
Switch.After the analogue simulation of one forecast failure, analogue system is restored to original state, then carries out next forecast failure
Analogue simulation.Whole process, the every corresponding forecast failure of row in above table, what is specifically executed is in simulation test sequence
Content.
(3) network prepared auto restart control strategy is judged：Then judge if there is following scenario described for each forecast failure
The control strategy of network prepared auto restart is correct：1) failure leads to load dead electricity, is then restored by network prepared auto restart control instruction
Load is powered；2) failure is not acted without result in load dead electricity, network prepared auto restart.
For other situations, then submits to dependence test personnel and do further artificial judgment analysis.
For table above, wherein preceding 3 forecast failures will not cause any negative because of the action of the interior prepared auto restart in station
Lotus dead electricity, therefore network prepared auto restart theory action situation should be failure to actuate.There is load after failure in 2 forecast failures afterwards
Dead electricity, therefore network prepared auto restart theory action situation should be that load restoration is powered.
High-volume control strategy test can be achieved in the present invention, effectively reduces the work of network prepared auto restart control strategy test
Amount, reduces demand of the dependence test to test equipment, helps to expand the popularization and application of network prepared auto restart.
It is enlightenment with above-mentioned desirable embodiment according to the present invention, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
