Distribution Network Sensor Selection Based on Improved Membership Function

The condition monitoring of distribution equipment is significant for safety and reliability of distribution network cooperation. In order to monitor the operating state of distribution equipment, first, we should learn about the function and characters of the different distribution and ensure the acquisition method to obtain the key characteristic quantity of distribution equipment. Then, we establish the system of comprehensive evaluation for the monitoring sensors application distribution equipment. Through the comprehensive evaluation of sensors, we can complete sensors selection and configuration and thus reduce the cost of monitoring system. To solve the ambiguity of sensors selection criteria, the author present two different comprehensive evaluation methods, one is aimed at applied object, other one is based on improved membership function.
