摘　　要：针对目前调度主站AVC系统和风电场无功补偿之间仍处于各自独立运行状态,使得全网无功调整需进一步优化的问题,首先对含风电场SVC的主站AVC系统进行建模,其次基于交流潮流约束,给出一种基于增量网络法的电网灵敏度分析方法,用于分析风电场SVC的调节对不同母线的电压影响,最后提出一种AVC系统和SVC的联调控制策略,以改善传统AVC控制策略的不足。仿真结果表明,该联调策略能有效改善电网电能质量,提高AVC运行效率。In view of the fact that the AVC system of the dispatching master station and the reactive power compensation of the wind farm are still in their independent operating states,the whole network reactive power adjustment needs to be further optimized.Firstly,the AVC system of the main station containing SVC of wind farm was modeled.Secondly,based on the AC power flow constraints,a grid sensitivity analysis method based on the incremental network method was given to analyze the influence of the wind farm SVC adjustment on the voltage of different busbars.Finally,a control strategy for joint debugging of AVC system and SVC was proposed to improve the deficiencies of traditional AVC control strategy.The simulation results showed that the joint debugging strategy could effectively improve the power quality of the power grid and the efficiency of AVC operation.
