Health status evaluation method of smart distribution station based on operation trajectory information matrix

Abstract

In order to solve the problem of real-time perception and evaluation of health status of smart distribution station, a health status evaluation method of smart distribution station based on operation trajectory information matrix is proposed. Firstly, the operation trajectory information matrix model of distribution station is established to record the development and change of environmental information and abnormal electrical quantity information in the distribution station for a certain period of time. Then, the development process of equipment state is divided into three stages: health state, sub-health state and disease state. The distribution station operation trajectory logic matrix is proposed, and the logic quantization of the distribution station operation trajectory information matrix is carried out. Finally, the distribution station operation trajectory logic diagram is established. The healthy development process of distribution station is discussed through the change of graphic area and volume. The health status of the distribution station is quantitatively evaluated through the distribution station sub-item health status evaluation matrix and the distribution station comprehensive health status evaluation index. Through the example analysis, it can be seen that the method is simple and fast, the abnormal and defective conditions of the equipment in the distribution station can be found in time, and the safe and economic operation of the distribution network can be ensured.
