A dynamic accident handling decision support system for regional power grid consider multi-constrains

A dynamic grid accident handling decision support system was developed for regional power grid from 220kV high voltage stations to power distribution network considering multi-constraints such as power supply recovery time, system stability, power supply reliability, and power supply loss. The developed system is designed as layering structure for logical layer and demonstration layer. And the system automatically obtains the grid data from PMS system, SCADA system and CIS system. It is modelled with the method of classification by weight of load and users. The expert database for dispatch rules is refined according to the general dispatch protocol and the grid dispatch protocol of Shanghai; it adopts the algorithm of tree traversal in order to analyse the fault corresponding to dispatch protocol on the basis of the user specified fault equipment and whole grid data model and establishes optimized plan.
