| 摘 要： | 介绍了一种基于专家系统理论的在线故障计算方法。该方法对传统的宽度优先搜索法进行了改进，并应用于形成节点阻抗矩阵的过程中，既解决了环网问题，又提高了计算效率。为方便故障计算，计算前对基本参数进行了处理和标识，将220kV侧电网做了系统外部等值。并编制了嵌入式故障计算软件，实现了与SCADA系统的在线数据交换。本软件已在线应用于吉林省辽源地区电网，运算结果表明，该算法能够满足实际应用要求。

| Abstract: | This paper introduces a method for on-line fault calculation based on expert system theory. The method ameliorates traditional method of width precedence searching, and applied to forming the nodal impedance matrix, settles loop net and advances calculation efficiency. The paper disposes and identifies the basic parameters and performs system exterior equivalent for 220kV network convenient for fault calculation. Moreover inbuih fault calculation software has been realized, can exchange data with SCADA system on-line. The software has on-line apply to Liaoyuan regional network of Jilin province, the result indicates the method can meet the demands of actual application. |
