Abstract

This paper presents a novel algorithm for estimation of line outages using phasor angle measurements. In this algorithm, phasor angles obtained from load flow simulation for various outage cases and thereby simulated bus power mismatches (SBPM) are to be stored. On occurrence of actual outage, bus power mismatches are to be computed using PMU provided post outage as well as pre outage phasors. Thereafter comparison between simulated bus power mismatches and computed bus power mismatches (CBPM) is done through least square norm minimization approach to find out the actual outage case. Moreover, random Gaussian noise with zero mean and standard deviation from 1% to 5% is introduced in the proposed model to check the feasibility in real power system. Performance of the algorithm is tested on IEEE 5bus, 14 bus and 30 bus system. The simulation results show the efficiency and viability of the proposed algorithm.

单线中断估计的一种新算法
本文提出了一种利用相角测量来估计线路中断的新算法。在该算法中,通过对各种停电情况的负荷流仿真得到相量角,从而对模拟的母线功率失配(smbpm)进行存储。在实际停电发生时,使用PMU提供的断电后和断电前相量来计算母线功率失配。然后通过最小二乘范数最小化方法将模拟母线功率失配与计算母线功率失配(CBPM)进行比较,找出实际停电情况。此外,还引入了均值为零、标准差为1% ~ 5%的随机高斯噪声,验证了该模型在实际电力系统中的可行性。在ieee5总线、14总线和30总线系统上对算法的性能进行了测试。仿真结果表明了该算法的有效性和可行性。
