基于信息融合的750kV电网二次设备状态评估
State Evaluation of Secondary Device in 750 kV Power Grid Based on Information Fusion
摘要
Abstract
To solve the problem that single state assessment method cannot fully and effectively use the multiplicate operating information of secondary device in 750 kV power grid, the state evaluation based on information fusion is proposed. By the use of self checking message, the state evaluation is carried out through the fuzzy comprehensive evaluation method. By the use of operation condition message,the state evaluation is carried out through Markov forecasting method. By the use of hidden failures data, the state evaluation is carried out through hidden failures diagnosis. Then, the D-S evidence theory is utilized to fuse the above three assessment results. The final evaluation result is derived to show that compared with the single assessment method, the state evaluation result of secondary device in 750 kV power grid based on information fusion is more approaching to the actual operating conditions.关键词
