Abstract: CPR1000+ technology is applied into Ling’ao Phase Ⅱ1000MW-class nuclear power plant for the first time in China. It is important of security and steady operation for nuclear power plants and grid to get the module parameters of turbine governing system by the simulation tests. Characteristics of ALSTOM half-speed turbine governing system are analyzed. Simulation test of half-speed turbine governing system is put forward. Results of simulation are analyzed and the parameters are identified. Module parameters of ALSTOM half-speed turbine governing system are acquired. It is highly important for Ling’ao Phase and Ⅱ CPR nuclear power plants to ensure safe and steady operation of long-term. -
