Inhalt:
The busbar fault probability of distribution network is high, which seriously endangers the safety of equipment. So, it is necessary to use busbar protection in distribution network. In order to improve the reliability of power supply, a scheme of busbar protection based on power direction is proposed, and the implementation plan that can adapt to different distribution systems are given. This protection can quickly identify and remove busbar faults, and is compatible with abnormal communication, switch failure and TV break. At the same time, it does not increase project investment and construction cost, which can be popularized in distribution network.
