摘　　要：针对南阳地区电网的实际情况,探讨了状态估计软件的基本原理和实现方法。在算法上采用P-Q快速分解法,具有较快的计算速度和较好的计算精度;在不良数据识别上采用数据预检测结合零残差识别法,辨识简便准确。经南阳电网数据检验,该方法实用,结果准确。The fundamental principle and method of the state estimation software for Nanyang power system are discussed in this paper. The software uses fast-decoupled method to get faster calculation speed and good calculation precision and adopts advanced data back-check and zero dispersion back-check method to make data identification easier and more corrective. The result tested by Nanyang power system shows that the algorithm is feasible and effective.
