摘　　要：基于重庆电网电压控制的特殊要求和电厂自动电压控制(AVC)系统的一般配置,针对重庆电网运行方式复杂的特点,给出了变增益的AVC控制策略。具体方法包括防止通信中断的指令编码方式和在电网发生大变动时减小调节增益的方式。实验表明,给出的AVC控制策略切实可行,可从电厂的角度进一步保证电网的电压控制安全。Based on the special requirement of voltage control in Chongqing power grid and the regular configuration of automatic voltage control （AVC） system in hydropower plant, this paper presents an AVC control strategies with gainscheduled for the characteristic of complicated operation modes in Chongqing power grid. The concrete method includes a command coding mode to avoid effect of communication interruption and a mode to reduce regulated gain when a large change occurs in the power grid. The test results showthat the given AVC control strategy is practicable and will benefit to the future test and operation of voltage control in hydropower plant.
