Abstract

At present, the distributed fault self-healing alarm rules of medium voltage distribution network are generally set to target type, and the range of fault self-healing treatment is limited, which leads to the decrease of unit alarm times. Therefore, the research on distributed fault self-healing technology of medium voltage distribution network under complex power supply topology is proposed. According to the current test requirements, the basic fault location and abnormal data collection are carried out first, and the multi-level method is adopted to break the limitation of fault self-healing treatment range, and the multi-level self-healing alarm rules are designed. Based on this, the distributed fault self-healing model of power grid under complex power supply topology is designed, and the self-healing treatment of power grid fault is realized by load verification. The test results show that in the selected six test areas, after three stages of testing, the number of unit alarms in the first test stage is finally controlled below 10 times, and it takes less time, which shows that the distributed fault self-healing method of medium voltage distribution network designed this time is more efficient, concrete and complete, and the pertinence is obviously improved, which has practical application value.
