Abstract
There is a risk of feeder over-current tripping in loop closing operation of distribution network. Without depending on the specific network parameters, a method for determining the closed loop in the distribution network is proposed so as to analyze the calculation method of voltage and power distribution in the distribution network, and a neural network model for determining the closed-loop distribution network is established. By calculating the power and current of the distribution network when the loop is closed, the purpose of determining whether the closed-to-be loop is closed or not is achieved. The specific example shows that the method takes into account the change of power flow in distribution network when the loop is closed, and the calculation of closed-loop current is more accurate and practical.
