摘　　要： 针对某省 2 0 0 2年实际背景电网 ,提出了在合理配置无功功率补偿容量前提下 ,基于变比及补偿容量调节对母线电压变化灵敏度的大小安排变比和补偿容量调整顺序和调整量的电压 /无功控制策略 .仿真分析表明 ,基于该策略制定的调整方案电压调整范围大 ,调压效果显著 ;满足同样调压要求所需的变比和补偿设备调整次数少、调整量小 ,不仅能提高电压合格率和系统电压稳定性 ,而且能显著降低系统网损 ,提高运行经济性 .本文所提出的电压 /无功控制策略 ,对于合理解决现代复杂电网的电压—无功综合协调控制具有较大的理论及实际意义 ,对于制定电力系统自动电压控制 (AVC)方案具有普遍借鉴意义 . Based on the actual power system condition in one of China′s provinces in 2002, the authors present a reactive power and voltage control strategy. This aims at adjusting the order and quantity of the transformer tap and the compensating equipment according to the sensitivity of the voltage variation resulting from the variation of the transformer tap and the compensating equipment. Simulation analyses have shown that the rectification range of voltage is extensive and the effect is remarkable with the above mentioned strategy. This strategy can lower the rectified number and degree of the tap and the compensating equipment. It can not only improve voltage eligibility rate and voltage stability, but also reduce power loss and enhance operation efficiency. This strategy to control reactive power and voltage has theoretical and practical value for automation voltage control (AVC) of the electric power system.
