DEVELOPMENT OF COMPUTER SUPERVISORY CONTROL SYSTEM OF EMS

In China, Energy Management System (EMS) becomes more and more important in power system control, but the practical application of EMS application software in domestic electric power companies is not satisfactory. Recently, the State Power Corporation of China asks the power control centres to enhance the practicality of EMSs and puts forward the evaluation standard. Because most of EMSs being applied in regional power system control centres and provincial power system control centres are imported and they do not have the evaluation and statistics functions, so that these dispatch departments are making efforts to achieve this aim. According to the requirement of State Power Corporation, the study and implementation on the computer supervisory control system of EMS are carried out. Combining with exterior programming, this system goes deep into the kernel of EMS, artificially sets up its operating parameters and can carry out the real time evaluation and supervision of operating status and results of EMS application software. Thus the function of EMS in Hubei provincial control centre is remarkably enhanced. Moreover, it can control some application modules of EMS such as State Estimation (SE) and Dispatch Power Flow (DPF).
