How to utilize the large scale data of dispatch center to solve the fault of power network effectively is very important.A new power network fault diagnosis system based on tabu-roughset is presented.It contains three modules,including data collecting,power network fault diagnosis and Web-based result display.In power network module,it utilizes roughset theory to form decision table on collected fault information,then to construct a discernibility matrix.Using tabu search can find the optimal result from the discernibility matrix,thus getting the correct power fault diagnosis quickly.The module of Web-based result display can provide the diagnosis with Web service according to the user's request by using visualization techniques.Experimental results show that the system based on the new method can find the best answer and better to achieve the power falult diagnosis.
