3) the customization guide of model reduction strategy can provide several kinds of equivalent tactful confession users of model automatically and select the reduction strategy, is selected the model that increases newly behind equivalent reduction model and the equivalence as required by manual work;
Model reduction strategy comprises the transformer equivalence at least becomes load, and the circuit equivalence becomes load or generator.
4) for artificial selection is intact reduce strategy after, the dispatching automation main station system is reduced strategy based on the equivalence of artificial selection and is reduced model, reduces the model that fallen by equivalence based on reducing device type and topological relation in the strategy;
The equivalent priority of handling of reducing is to reduce transformer trail official circuit earlier from high to low.
For transformer, it is carried out equivalence after, according to topological relation all equipment that link to each other with this transformer of search and reduce; If in the equivalent reduction process of transformer, find have other transformers to link to each other with this transformer, but the artificial equivalence of other transformers of definition of not selecting is reduced strategy, and other transformers will be reduced according to the reduction strategy that has defined so; Defined equivalent circuit as if having in the equipment of in the equivalent reduction process of transformer, finding to be reduced, then this circuit is no longer done the equivalent processing of reducing; For circuit, after it is carried out equivalence, then need reduce this circuit.
5) after model is reduced and accomplished, increase new Equivalent Model according to device type and the topological relation reduced in the strategy.
For transformer, after reduction is accomplished, equivalent sign will put on the transformer; For circuit, after reduction was accomplished, if search the equipment that links to each other with this circuit in the our station side of this circuit, an end that then links to each other with circuit at this equipment hung up newly-increased model.
After transformer has been done equivalence in the corresponding model, all will delete, after sweep equipment is accomplished, put equivalent sign on the transformer with the mesolow side all devices that this transformer links.After corresponding line had been done equivalence, this circuit will be deleted, to hanging up the equivalent machine utilization or the generator of artificial appointment on should circuit our station end node.If after finding the transformer equivalence, the equivalent circuit of selected needs is deleted, then this circuit is no longer done the equivalent processing of reducing.As after finding the transformer equivalence, other do not select equivalent transformer to link to each other with this equivalence transformer under the identical electric pressure, and then other transformers also need be done with the same equivalence of equivalent transformer and reduce processing.
6) with dispose back and increase the model after the new Equivalent Model of reduction, import said dispatching automation main station system.
The function that the present invention realizes comprises three parts:
(1) in transformer station, send in the model, extract needing equivalent model by electric power system general knowledge;
(2) based on the Equivalent Model that extracts, the equivalent strategy of reducing is provided, artificial requirement-based selection finally needs equivalent model and the new model type behind the equivalence;
(3) will be reduced by the model of equivalence according to the topological relation of model and the definition of manual work before, and add the new model behind the equivalence.
