A new system of operation ticket for generation and misoperation prevention in smart distribution network

A solution of switch operation ticket system is proposed to improve its versatility and maintainability. The object oriented expression mode is used in the single line chart modeling to realize its automatic initialization. The manual operation ticket generation is implemented by equipment selection and operation selection. According to the operating rules of distribution network, the reasonable verification against misoperation is carried out. Like the way of experts´ thinking, the system separates the primary equipment operation from the secondary equipment operation and realizes the automatic operation ticket generation. The layered operating rule templates are adopted, the operating rules are classified according to equipment type and saved in database, and the excellent man-machine interface is provided for modification. The system is convenient for ticket generation, easy to be maintained, and works accurately, which has been successfully applied to a municipal distribution network.
