doi:10.11930.2015.2.85

Abstract

Abstract: In this paper, a summary is made of the problems existing in measurement and model validation of the state estimation (SE) module of the North China Power Grid Smart Grid Operation Support System(SG-OSS), and the limitations of the existing SE are pointed out in operation of the real system. According to the defect that the existing SE can only provide the calculation functions but cannot make intelligent analysis of the real data, it is proposed to build the intelligent analysis function of SE to enhance the real project application effects of the SE. The intelligence analysis functions include such modules as measurement error check, intelligent analysis, problem location, result display and query, which can make the measurements error be located. The operation in the North China power grid SG-OSS shows that the intelligence analysis capabilities can accurately locate the data errors of power grid, which can improve the quality of basic data and the efficiency of automatic maintenance. The operation results indicate that the system can be widely applied.

Key words: state estimation, parameter identification, model check, measurement error check, intelligent analysis
