The Research And Application Of The Regional Network Fault Restoration System

After the occurrence of the power network fault, the dispatcher must take some measures quickly and handle fault effectively for the minimum fault loss.So studying a practical fault restoration system has very important practical significance to assist the dispatchers to handle the fault quickly.Based on the existing fault restoration and processing system, a function module of post-fault loss of load statistics is developed for the intelligent decision support system for Ordos region power grid. The result of tests are rational and correct. Aiming at the shortage of the developed overload processing module, a new overload processing method is researched. It first searchs the transfer paths for the load bus which can eliminate overload and has the minimum load transfer. the redundancy of transfer path is estimated before choosing the path of transfer load and According to it to evaluate the transfer path or determine the newly arisen Overloading equipment .Moreover, the further treatment of the newly arisen overload in transfer path is made to realize the load continuous transfer. So the more reasonable scheme of overload processing is gained to provide the decision-making support for the dispatchers. Finally,the test cases verify the validation of this method.
