摘要

针对3/2接线方式变电站开关电阻在线计算的问题，提出了一种基于遗传算法的计算方法。利用流过开关设备的电流和开关电阻建立最优规划模型，将计算开关电阻的问题转化为解决最优规划问题。在计算过程中，采用遗传算法可以避免传统方法求解多维空间规划问题带来的复杂性。用某500 kV变电站的实测电流数据进行仿真计算，验证了该方法的可行性。%Aiming at the online calculation problem of 3/2 wiring connection switchgear resistance, this paper proposed a kind of online calculation method based on genetic algorithm. By the use of the current and resistance of the switching equipment, the opti-mal planning model was established, and the problem of calculating the resistance of the switching equipment was transformed into an optimal planning problem. In the process of calculation, instead of conventional method, the genetic algorithm was used to avoid the great complexity caused by solving the problem of multidimensional space planning. Based on the current data obtained from the 500 kV substation, simulation studies are carried out and the results verify the effectiveness of the proposed method.
