Abstract

To maintain security and adequacy in a bulk power system, FERC's Order No. 888 in 1996 specified six services called ancillary services that the electrical transmission providers must provide. These six services constitute system control, reactive supply and voltage control, regulation, operating spinning reserve, operating supplemental reserve and the energy imbalance. Besides these six services, there are additional six services for which the transmission providers are not responsible. These six services constitute load following, backup supply, real power loss, dynamic scheduling, black-start capability and network stability. Despite the extensive preparations and planning by the ten electrical grid Security Councils, the combination of generation unavailability and limited transmission capability coupled with unanticipated circumstances such as extreme weather conditions could result in shortages of generation sources for reactive supply (VArs) and voltage control that could affect the security of the electric grid. This paper discusses mainly the reactive and voltage control portion of the ancillary services associated with the interconnected electric grid.

辅助服务——无功和电压控制

为了维持大容量电力系统的安全性和充分性，FERC在1996年的第888号命令规定了电力传输供应商必须提供的六种称为辅助服务的服务。这六项服务包括系统控制、无功供电和电压控制、调节、运行纺丝储备、运行补充储备和能量不平衡。除了这六种服务之外，还有另外六种传输提供商不负责的服务。这六项业务分别构成负载跟踪、备用供电、实际缺电、动态调度、黑启动能力和网络稳定性。尽管十个电网安全理事会进行了广泛的准备和规划，但发电不可用和有限的输电能力加上极端天气条件等意外情况可能导致无功供电(var)和电压控制的发电源短缺，从而可能影响电网的安全。本文主要讨论了与互联电网相关的辅助业务的无功和电压控制部分。
