What is the difference between primary frequency modulation, secondary frequency modulation and tertiary frequency modulation in power system?
The governor realizes primary frequency modulation, but cannot realize differential frequency modulation. Each generator set has a governor, but the response is relatively rapid.
The secondary frequency modulation is realized by frequency modulator, which can realize lossless frequency modulation. Usually, the secondary frequency modulation is only carried out by the generator sets of a few power plants selected by the system.
The third frequency modulation is the optimization of power, which minimizes the loss in the process of power transmission or the coal consumption of power plants, and achieves economic optimization.
