Study on the optimal maintenance period for relay protection device

Since the optimal maintenance period for relay protection device is difficult to determine, this paper in- troduces the failure distribution model for relay protection, analyzes the relation between model parameters and fail- ure process, proposes the constraints of economy and reliability, and according to the history failure and experience data simulates and analyzes the model by Matlab. Calculation result shows that the method based on non - homoge- neous poisson process is able to simply and effectively calculate the optimal maintenance period for relay protection device, which provides theoretical foundation for plan of relay protection maintenance and application of condition - based maintenance.
