上海电网220 kV统一潮流控制装置示范工程应用效果分析

Analysis of application effect of 220 kV UPFC demonstration project in Shanghai Grid

结合上海特大城市电网特征和实际运行需求,分析了上海220 k V电网加装统一潮流控制器装置(UPFC)的必要性。确定了UPFC示范工程合理的选址方案,提出了220 k V蕴藻浜站UPFC示范工程的电气主接线、主设备参数以及控制策略。基于实时闭环仿真平台研究了加装UPFC对上海电网的影响。通过仿真验证了UPFC示范工程在提升电网传输能力、改善电网电压稳定性、实现分区无功就地平衡等方面的多重应用效果。

The feasibility study of UPFC application in 220 kV Shanghai Grid is conducted based on characteristic and practical operation of Shanghai megacity grid. The reasonable location scheme of the UPFC demonstration project is determined, and main electrical connection, parameters of the main equipment and control strategy of 220 kV Yunzaobang station UPFC demonstration project are proposed. Based on the real time close-loop simulation platform, the influence of installing UPFC on Shanghai power grid is studied. The simulation results show that the demonstration project of UPFC has multiple application effects in terms of enhancement of power grid transfer capability, improvement of grid voltage stability performance and contribution to local balance of partitioned reactive power.
