摘 要：火電廠設(shè)備健康數(shù)據(jù)提取是火電廠設(shè)備狀態(tài)評估數(shù)據(jù)處理的一個關(guān)鍵步驟，有利于提高設(shè)備狀態(tài)評估的準(zhǔn)確性與效率。將設(shè)備狀態(tài)數(shù)據(jù)首先利用R 型層次聚類進(jìn)行特征參數(shù)選取與冗余數(shù)據(jù)清除，再采用自組織神經(jīng)網(wǎng)絡(luò)篩選異常值。利用所訴方法對某發(fā)電廠的汽泵前置泵設(shè)備的監(jiān)測數(shù)據(jù)進(jìn)行健康狀態(tài)數(shù)據(jù)提取，發(fā)現(xiàn)清除的異常數(shù)據(jù)遠(yuǎn)遠(yuǎn)大于提取出的健康數(shù)據(jù)，表明該方法清除的數(shù)據(jù)滿足預(yù)期，為后續(xù)健康狀態(tài)評估提供了準(zhǔn)確的參照數(shù)據(jù)，并且降低監(jiān)測數(shù)據(jù)維度提高評估效率。
關(guān)鍵詞：大數(shù)據(jù)；自組織神經(jīng)網(wǎng)絡(luò)；R 型聚類；電力設(shè)備狀態(tài)數(shù)據(jù)

Abstract: The health data extraction of thermal power plant equipment is a key step in the processing of equipment state assessment of thermal power plants, which is conducive to improving the accuracy and efficiency of equipment state assessment. The power equipment status data were carried out characteristic parameters selection and redundant data eliminating by R-type hierarchical clustering, then the outliers of device status data were filtered by self-organizing neural network. The proposed algorithm was used to extract the health status data from the monitoring data on turbine pump booster pump device in certain power plant. It is found that The clearing abnormal data is far greater than the extracted health data, which indicates that the algorithm meets the expectation. This algorithm provides the accurate reference data for subsequent health assessment, reducing the monitoring data dimension and improving evaluation efficiency.
Key words: big data; self-organizing neural network; R-type clustering; power equipment status data
