Research of Power Grid Fault Diagnosis and Intelligent Analysis Method Based on Multi-Source Information

With the integration of scheduling and control promote, the warn processing function of existing power dispatching automation system such as energy management system need improved. In order to facilitate the supervisor of Power Dispatch and Centralized Control Center to understand the operation state of the power grid accurately, the warn processing function distributed in each system should be processed synthetically. This paper presents a noval method for Power system fault diagnosis and intelligent analysis based on fusion of multi-source information; it can determine the location of the fault quickly then make reference decisions. It can not only improve the efficiency of supervisor but also avoid accident and abnormal further expansion.
