在研究电网行波故障定位方法的基础上,提出了一种行波故障定位装置的优化配置方法。该方法首先依据配置原则对电网中的变电站配置行波定位装置,然后利用模拟退火算法对初始方案进行优化,将配置过程和优化过程有效结合后提高了初始配置方案的质量,缩小了模拟退火算法的寻优范围,从而提高了求解速度。实际系统的配置分析和仿真结果表明适当的优化配置可以在不影响定位可靠性和准确性的前提下减少定位装置的布点,从而有效节省投资。
Based on the research of traveling wave fault location method in power system, an optimization method of traveling wave fault location device is proposed. The method firstly configures the traveling wave locating device for the substation in the power grid according to the principle of configuration, and then optimizes the initial solution by using the simulated annealing algorithm. The combination of the configuration process and the optimization process effectively improves the quality of the initial configuration solution and reduces the size of the simulated annealing algorithm The scope of optimization, thereby improving the speed of solution. The actual system configuration analysis and simulation results show that the appropriate optimal configuration can reduce the location of the positioning device without affecting the reliability and accuracy of positioning, thus effectively saving investment.
