Abstract

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.
