摘要
为提高电力系统电压稳定性,研究了一种通过为常规发电机励磁系统增加补偿控制的先进的高压侧电压控制(HSVC)。介绍了HSVC的原理、特性和优点。与常规的励磁控制方法相比,采用HSVC能够控制升压变压器高压侧电压为给定值,维持输电系统在较高的电压水平。HSVC可以显著地改善电压稳定性,其某些性能优于静止无功补偿器。不同于以往的电力系统电压调节器(PSVR),HSVC的实现不需要从升压变压器高压侧反馈任何信号,所以实现方便并经济。
The power system voltage stability was improved by adding supplemental control to a conventional automatic voltage regulator (AVR), which was named as advanced high side voltage control (HSVC). This paper describes the principles, and advantages of advanced HSVC to that of conventional AVR with a static var compensator. With the advanced HSVC, the high side voltage of a step-up transformer can be controlled to a set value and maintained to a higher value than with conventional excitation systems. This advanced HSVC is realized without any feedback signal from the high side voltage side of the step-up transformer and so it is relatively low-cost and easy to implement.
