摘要
以地区电网具体合环实例介绍了PSASP合环电流计算方法,并针对调度员在合环操作前快速了解合环电流大小的需求,提出了基于PSASP模型的快速计算方法,并验证了计算精度。同时针对运方人员对计算精度和实时在线计算的需求,介绍了省地一体联合优化计算系统合环潮流计算工具以及当前的应用情况。探讨了合环电流的快速计算和准确计算方法,确保合环操作成功及电网的安全运行。
The paper introduces the calculation method of PSASP closing current by taking Nanjing regional power grid as an example,and in view of the dispatcher's need to quickly understand the size of the closing current before the closing loop operation,it proposes a fast calculation method based on PSASP model and verifies the calculation accuracy.Meanwhile,in the light of operation personnel’s needs for real-time online calculation and accuracy,it introduces the closed-loop power current calculating tool of the provinceregional integrated optimization system and its present application.The paper also discusses the fast and accurate calculation methods of closing-loop current to ensure the success of closing-loop operation and the safe operation of power grid.
