系统频率波动还会引起发电机组转速发生变化，此时，原动机调速器动作，调整

System frequency fluctuations will also cause changes in the speed of the generator set. At this time, the prime mover governor operates to adjust the power of the prime mover. When the system frequency drops, the governor controls the steam turbine valve opening to increase, increasing the prime mover power; when the system frequency increases, the governor controls the steam turbine valve opening to decrease, reducing the prime mover power. The adjustment characteristics of this kind of generator set are usually described by the adjustment rate 8.

System frequency fluctuations can also cause changes in the speed of the generator set, at which point the primary motivation regulator moves to adjust the power of the primary motivation. When the system frequency decreases, the regulator controls the turbine door opening increases, increasing the primary motivation power, and when the system frequency increases, the regulator controls the turbine door opening decreases, reducing the primary motivation power. The tuning characteristics of this generator set are usually described with a tuning rate of 8

The system frequency fluctuation will also cause the generator speed to change. At this time, the prime mover governor acts to adjust the power of the prime mover. When the system frequency decreases, the valve opening of the turbine controlled by the governor increases, increasing the power of the prime mover; when the system frequency increases, the valve opening of the turbine controlled by the governor decreases, reducing the power of the prime mover. The regulation characteristic of this kind of generator set is usually described by regulation ratio 8<br>
