Reliability Analysis Method of Power Quality Monitoring Device based on Non-Parametric Estimation

The quality of power quality monitoring device will affect the orderly development of the on-line monitoring and evaluating work. Yet with parts of the long-running in complex operating conditions and aging of components, the power quality monitoring equipment may cause reduction of reliability, which affects the accuracy of data quality. Therefore, an operation reliability analysis method for power quality monitoring equipment based on nonparametric estimation was presented in this paper, which could actualize the remote analysis and evaluation of reliability for the power quality monitoring equipment that benefits discovering the hidden peril in reliability reduction and improving management level of power grid companies. The practice proves the feasibility and validity of the method.
