Power system the main method is to adjust the power frequency adjustment and load management。 Primary frequency control is to point to when power system frequency deviates from the target frequency generator set automatically by the speed control system of reaction ， active efforts to maintain stability of power system frequency adjustment. Secondary frequency modulation, also known as the automatic generation control refers to the adjustable generators provide sufficient capacity and a certain adjustment rate， real—time tracking frequency under the allowed to adjust deviation ， in order to meet the requirements of system frequency stability 。 Three frequency modulation is to coordinate the economic load distribution between the various power plants， so as to achieve economic and stable operation of the power grid。 Key words ： Electric system ， A frequency modulation ,The two FM The three FM ， Review 引言“频率”概念源于针对周期性变化的事物的经典物理学定义， 由于电力系统...
