A DISCUSSION ON SOME PROBLEMS IN APPLYING EMS TO REGIONAL POWER NETWORK

After the implementation of applying SCADA systems to region power network, it begins to built up the EMS for regional power network. The usability, practicability and reliability are the important indices in the judgment of the performance of EMS. Because the basic automation level in regional power network is weaker than that in provincial power network, therefore, it leads to that it is difficult to implement and apply power system application software (PAS) in regional power network, so that the implementation project and the functions of PAS for regional power network should be different to that for provincial power network and above. According to the practice in Taiyuan Power Supply Bureau the features, current situation, necessity, principle of implementation and obstruction of applying PAS to regional power network are put forward, and the suggestions on the concrete improvement and application of several functional modules in PAS suitable to regional power network, e.g., network topology, state estimation, load forecasting, on line power flow, security analysis, reactive power optimization and short current calculation, etc., are given.
