摘　　要：水电厂自动电压控制(AVC)的总体目标是根据电网要求,考虑电厂及机组的运行限制条件,使电厂电压稳定安全。文中首先介绍电厂侧AVC系统的一般要求,然后以柘溪电厂为例,具体阐述包括功能约束和保护闭锁的AVC策略,在PQ曲线限制的实现和提高电压调整精度方面进行了重点分析,实验表明考虑无功进相的AVC系统切实可行,调节跟踪精度在0.4 kV以内。The main target of automatic voltage control（AVC） for hydropower plants is to stabilize voltage with safe and effective method in accordance with operation restriction condition of the units and the power plant.With generators of Zhexi Hydropower Plant,Hunan as an example,the policies of AVC,such as function restrictions,boundary condition and protection locking strategy for AVC are expatiated.And implementation of PQ curve restriction and high accuracy of voltage control are analyzed in detail.The test results illustrated in this paper will benefit to the future test and operation for Hydropower Plants＇ AVC.
