摘　　要：电压质量作为衡量电能质量的指标之一,对电力系统的安全稳定与经济运行至关重要。自动电压控制(AVC)的控制模式分为集中控制和分散控制两类,主站的无功电压控制也有集中与分散两种控制模式。针对主站AVC的分散控制的动态优化控制模块,建立了数学模型,利用改进经济压差算法求得该模型的最优控制策略,最后通过算例验证了该算法的精确性与实用性。Voltage quality is one of important indicators of power quality, and it has a major impact on the stability and safe operation of power grid. The control modes bf automatic voltage control （AVC） include decentralized and centralized control, and voltage and reactive power control in master station also include these two modes. The paper constructs the mathematical model for the dynamic optimization control module of the system, and uses improved economic voltage difference algorithm to obtain the optimal control strategy of the model. Calculation example verifies the accuracy and practicality of the algorithm.
