2) described dispatching automation main station system is resolved this model, and extract equivalent equipment by electric power system general knowledge, the information that extracts comprises the affiliated electric pressure, rdfid sign of this equipment etc. at least, and by electric pressure, device type is selected the displaying of classifying of the equivalent equipment of these extractions for artificial definition;
According to the general knowledge of electric power system, generally, scheduling station might be done equivalent the processing to transformer or circuit, and equivalent state estimation, the dispatcher's trend of making things convenient for later calculated, and keeps the equipment that the dispatcher pays close attention to simultaneously.
3) the model customization guide of reducing strategy several strategies that can provide the model equivalence automatically select to reduce strategy for the user, by the artificial newly-increased model of equivalent reduction model and equivalent back of selecting as required;
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 according to the equivalence of artificial selection and is reduced model, reduces the model that fallen by equivalence according to reducing device type in the strategy and topological relation;
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, search for all equipment that link to each other with this transformer and reduce according to topological relation; If find have other transformers to link to each other with this transformer in the equivalent reduction process of transformer, but the artificial equivalence of other transformers of definition of not selecting is reduced strategy, and other transformers will be reduced according to defined reduction strategy so; Defined equivalent circuit as if having in the equipment of finding to be reduced in the equivalent reduction process of transformer, then this circuit is no longer done the equivalent processing of reducing; For circuit, after it is carried out equivalence, then need to reduce this circuit.
5) after model is reduced and finished, increase new Equivalent Model according to device type and the topological relation reduced in the strategy.
For transformer, after reduction is finished, will on putting, transformer indicate by equivalence; For circuit, after reduction was finished, if search the equipment that links to each other with this circuit in the our station side of this circuit, then an end that 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 with the mesolow side all devices that this transformer links, after sweep equipment is finished, equivalent sign on transformer is put.After corresponding line had been done equivalence, this circuit was deleted, to hanging up 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 the equivalence reduction processing same with equivalent transformer.
6) reduction is disposed back and increase model after the new Equivalent Model imports described dispatching automation main station system.
The function that the present invention realizes comprises three parts:
(1) send in the model in transformer station, extract needing equivalent model by electric power system general knowledge;
(2) according to 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 artificial definition before, and the new model behind the interpolation equivalence.
The beneficial effect that the present invention reaches:
Method of the present invention makes the user can according to the actual requirements transformer station model be carried out importing main station system again after equivalence is reduced processing, satisfy the requirement that the user imports as required to transformer station model, and the equivalence that offers the multiple mode of user flexibly is tactful, making the personnel that use the dispatching automation main station system just carry out equivalence to transformer station model before the transformer station model import system handles, reduce unwanted model, make that the model of final import system is complete and keen-witted and capable.What be convenient to the user dailyly uses and manages, and has reduced useless device model and has imported pressure to system load, has improved fail safe and the practicality of the synchronous main station system of transformer station model.
