| 摘 要： | 设计了无功优化控制系统的软件体系结构,建立了动态无功优化数学模型。提出的地区电网无功优化控制基于现有地调自动化系统,在母线负荷预测的基础上,利用遗传算法求解整个电网的无功优化问题,得到的优化结果为各个变电站VQC的合理限值。该方法将全局优化与VQC分散控制的优点结合起来,克服了各变电站无功、电压就地最优控制的弊端,节电效益显著。在某地区电网的应用中验证了该系统和方法的有效性,经过优化计算,在满足电压约束和控制设备投切次数限制的条件下,降低了电能损耗,有功损耗比优化前下降约3个百分点。

| Abstract: | The software structure of the reactive power control system is designed. Dynamic reactive power optimization model is established. Genetic algorithm has been used to complete the reactive power optimization. This paper studies how to build appropriate VQ limits according to the calculation of reactive power optimization. When deciding VQ limits of VQC, the range of reactive control is calculated. The reactive power optimization program has been validated in a local power system. The power loss has dropped by 3% after optimization in that power system. |
