PSD-BPA Model of Governor of Water Turbine Microcomputer and Its Application

For providing PSD-BPA model suitable for governor of water turbine microcomputer for power system transient state stability analysis, according to typical structure of governor of the water turbine microcomputer, this paper chooses regulating system model 4 （GM card） and electro hydraulic servo system mode （GA card） provided by 4. 15 edition PSD- BPA transient stability program to respectively represents two constituent parts, one is microcomputer governor and the oth- er is mechanical hydraulic system. Meanwhile, it proposes meanings and access methods of parameters in these two models and carries out simulation on parameters of governor of some water turbine microcomputer. It discovers that response of the governor with step disturbance of different amplitude frequency is agreed with reality which indicates that links of the gover- nor model are considered comprehensive and parameters are agreed with reality and easy to be get for correctly simulate practical working of the governor in transient state process of power system.
