Identification Method of Main Electrical Connection and Attribute of Bay

In order to realize the verification of the anti-misoperation rules of the electrical switch, it is necessary to automatically divide bays and identify the attributes of bay and the type of main electrical connection in the power grid or substation model data. With the goal of identifying the main electrical connection, the article formulated the classification principle of switch bays. According to the principle, the circuit breakers and isolating switches are classified into circuit breaker bays or isolating switch bays. Based on a clear data base and functional requirements, the paper summarized the characteristics of switch bay in each electrical connection. Considering that a voltage level contains a variety of main electrical connections or incomplete main electrical connections, the article proposed the corresponding identification method of main electrical connection and the attributes of bay. On this basis, the overall analysis process is designed. Through the case data test, the effectiveness of the above method is verified.
