Evaluation of Distribution Automation Terminal Based on Grey Relational Method

Improving distribution automation is one of the keys to build a strong smart grid. Since the current distribution automation terminal numbers are various, and the traditional maintenance workload is heavy at present, but there is a correlation between each impact index and failure, the article has established the assessment system of distribution automation terminal based on the theory of the grey clustering evaluation way, and the state evaluation of the distribution automation terminal is carried out, and the correctness of the method is verified by calculation. Grading detail rules of each state variable have been given for distribution automation terminal state control and providing a decision-making basis.
