【 摘 要 】

Frequency is one of the most important parameters reflecting the operation quality of the system. When the system is in steady-state operation, the frequency of the generator in the system is equal under steady-state operation. Because the load is changing at any time, this kind of balance is dynamic. The only way to maintain dynamic balance is to adjust the input power of the generator, so that the actual output of the generator can closely track the change of the load and keep the balance between supply and demand of active power. The essence of frequency control is to regulate and control the active power of all generators in power grid. In this paper, the principle of frequency fluctuation is analyzed, and the physical models of the primary and secondary frequency modulation are established. The simulation results verify the differential regulation of the primary frequency modulation and the no-difference regulation of secondary frequency modulation. It provides an effective basis for the later research of AGC control strategy.
