The computer simulation technology is used to study the frequency disturbance of water turbine governing system (WTRS).Under no-load frequency disturbance condition,the parameters of governor and the controlled system are changed to do the simulation experiments.The simulation results show that the different parameters combinations have great influences on the system ’s performances under frequency disturbance condition.In addition,the simulation experiments in Simulink environment can seek to find the parameter combination which can make the governing system achieve good control effect under frequency disturbance condition.The simulation experiments can not only strengthen students’understanding of the PID adjusting rule for frequency disturbance of hydroelectric generating set,but also improve the students’ability of using the computer technology to provide theoretical basis and evaluation for the practical engineering problem of WTRS under frequency disturbance condition.
