PMU在电力系统中的优化配置方法

Optimal PMU placement in power system

相量测量单元(PMU)已广泛应用于电力系统状态估计、系统监测和稳定评估.PMU的优化配置问题是当前电力系统相量测量技术的一个重要问题.在深度优先搜索法的基础上,通过改进寻优规则,并考虑发电机、负荷以及网络结构等因素的影响,提供一种较为简便的方法实现该问题的求解.利用IEEE 14,IEEE 30等系统中的验证结果表明,改进算法可以较少的PMU安装数量实现电力系统的可观.

With the development of wide area measurement technology,phasor measurement units（PMU） now have been widely used in power system state estimation,system monitoring and stability assessment.Currently,optimal PMU placement has become an important issue in the wide area application.In this paper,an improved depth-first search method for optimal PMU placement is presented.In the method,searching routine is optimized,and the impact of generators,loads and system structure to the optimal solution is also considered.The proposed method is validated by the IEEE-14 and IEEE-30 systems.It is found that the method can give a better solution with more effectiveness.
