摘　　要：电压是电力系统运行的重要指标之一,无功电压控制是提高电压质量、降低网损的重要技术手段。现实中,无功电压控制有难点。自动电压控制(AVC)对发电机组、电容器/电抗器等多种无功调节手段进行全网优化闭环控制,提高无功电压安全经济运行水平。对于AVC的关键技术研究,为保持系统电压稳定、提升电网电压品质和整个系统经济运行水平、提高无功电压管理水平提供了重要技术手段。Vohage is an important index of power system operation, anti reactive power control is the important technical means to im- prove the quality of vollage and rc（hwe lhe loss of power system. In reality, the reactive power and voltage control is difficuh, automatte vohage control （AVC） for generating set, capacitor, reactor, and as a variety of reactive power regulation methods of closedloop control for the entire network optimization, whievh improves lhc level of reactive vohage security and economic operation. Key technology research for AVC provide an important technical method to mainatain the system vohage stability, to improve the quality of power grid voltage and the eeonomie operation level of the whole system, and to improve the level of reactive vohage management.
