发电机通常通过自动电压调节器和励磁设备来调节终端电压。所需的高侧(输电侧)电压调度表通常由发电厂操作员或速度较慢的SCADA型过程控制计算机维护。然而，电力系统的动态性能可以通过更快地调整输电电压来改善。与发电机不同，静止无功补偿器是专门为输电电压调整而设计的。传输电压在高速时直接调节。总SVC和中压分量无功功率额定值是指输电侧。所有中压设备的设计都支持输电侧无功和电压调节的要求。与调节终端电压的发电机相比，下垂(斜率)设置通常较小。本文介绍了关于二次电压控制的专题讨论会。作者概述了加强高压侧电压控制的各种方法，重点介绍了美国太平洋西北部地区的水力发电控制。
Generators typically regulate terminal voltage via automatic voltage regulator and exciter equipment. The desired high side (transmission side) voltage schedule is usually maintained by the power plant operator or by slow SCADA-type process control computers. Power system dynamic performance, however, can be improved by faster regulation of the transmission voltage. Contrasted to generators, static VAr compensators are designed specifically for transmission voltage regulation. The transmission voltage is directly regulated at high speed. Total SVC and medium voltage component reactive power ratings are referred to the transmission side. All medium voltage equipment are designed to support the transmission side reactive power and voltage regulation requirements. The droop (slope) setting is usually small compared to generators regulating terminal voltage. This paper introduces the panel session on secondary voltage control. The author outline various methods for tighter high side voltage control, with emphasis on control of hydro generation in the US Pacific Northwest.
