| 摘要: |
| 配电网络合环操作时，一般只验证合环后稳态电流是否会造成潮流超过设备限额，而没有考虑合环瞬时的最大冲击电流对电网的安全、稳定运行的影响。为此提出了计算舍环最大冲击电流的方法，给出了合环冲击电流计算的数学模型及计算方法和计算流程图．并根据现场实际情况编写程序对此过程进行模拟。目前，该系统已在江苏大丰、靖江配电网络系统中投入运行，实际应用表明，该方法对电网实际运行有一定的指导意义。 |

| Abstract: |
| Maximum surge current due to closing loop in distribution grid is not taken account of at present,which affects security and stability of the system. This paper brings forward a method to calculate the maximum surge current and simulate the whole process by programming. Its mathe-matical model,calculating means and flowchart are presented. Applications in local distribution systems show that the proposed method has reference meaning for the system operation. |
| Key words: distribution grid,close loop,surge current |
