利用发电机组无功出力调整总降变电所功率因数

Use of Reactive Power Output of Generating Set to Control Power Factor of Step Down Substation

同步发电机组通过自动电压调整装置,可以实时地监控发电机出口电压,通过改变励磁电流来调发电机组的无功出力,以适应系统电压的变化。利用这一特点,可以实时地调整自备电厂的无功出力,实现总降变电所功率因数动态平滑的调整。

A synchronous generating set can real-time monitor outlet voltage of a generator by the automatic voltage regulation device. The reactive power output of the generating set is controlled by changing the excitation current to adapt to the change of system voltage. Use of this feature can real-time control reactive power output of the self-provided power plant to realize dynamic smooth adjustment of power factor of the step down substation.
