中文摘要：

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。

英文摘要：

Based on study on traveling wave fault location method for power grid, an optimal placement method of traveling wave fault location equipment （TWFLE） is proposed. First, several substations in the power grid are selected to install TWFLE according to placement principles. Then initial placement scheme is optimized with simulated annealing method. The effective combination of placement process with optimized process improves the quality of initial TWFLE placement scheme, and minimizes the searching scope of simulated annealing method , so that the solving process is accelerated. Placement analysis and simulation results of an actual power grid shows that proper optimal placement can reduce the number of TWFLE without influence on reliability and accuracy of fault location. So it can save investment effectively.
