Abstract:By analyzing faults occurring at load side of a power network,it is concluded that domestic thermal power units have poor primary frequency modulation performance.Optimization was performed on control strategy of primary frequency modulation of domestic 2×600 MW thermal power units in Zhuhai Jinwan Power Generation Co.Ltd.Measurement results respectively carried out before and after the optimization prove the control strategy to be helpful in raising both the response speed of primary frequency modulation and the lasting response capability,hence the stability and safety of power network are improved.
Keywords:power network  thermal power unit  primary frequency modulation  control strategy
