Simulation research on the operation method of live breaking or connecting of no-load and connecting lead cable in 10 kV distribution network
Live breaking and connecting no-load power cable lead operation,which is the most characteristic 10 kV non-power outage operation project,is taken as a typical example to analyze the mechanism of transient operating overvoltage and overcurrent in the operation process.The simulation model of 10 kV distribution network under different operating conditions is established by using ATP-EMTP software,and the transient and steady electrical characteristic values during the operation of the live breaking or connecting no-load cables and the connecting lead of overhead lines are calculated.The feasibility to promote of live breaking or connecting of no-load cable and overhead line connecting lead and is further analyzed,and the safety operation procedures and risk prevention and control key points are put forward.Finally,virtual reality technology is used to simulate the operation process,and the feasibility and safety of this operation requirement are verified.It provides a theoretical basis for the development of 10 kV live breaking or connecting non-loaded cable lead connection operation project,and lays a foundation for further improving the live operation rate of distribution network.
