Explore the applicability of principal component analysis in monitoring a hydroelectric generating unit
A model for monitoring system anomalies based on principal component analysis was established by MATLAB,and the historical data in plant level information system of hydropower station were used to analyze the routine operation state of the hydroelectric generating unit.The principal component analysis is proved to be applicable for monitoring the operation state of the hydroelectric generating unit under limited operation conditions and by using the limited measurement points.Parameter analysis could be used to have effect of early warning under appropriate parameters,which provides a new way to improve the capability of software analysis without adding monitoring hardware in hydropower stations.
