Reliability Evaluation and Prediction of Low Voltage Distribution Network

Forward and backward substitution method has been used as the power flow calculation method of any low voltage distribution network, and therefore utilization rate of electrical energy of the lines, transformer and line loss are obtained. These are the datum to assess the reliability of low voltage distribution system, and to reflect the level of reliability of power supply of the whole distribution system. At the same time, reliability indices of the low voltage distribution network are predicted by the method of probability and statistics. According to the reliability evaluation and prediction of the distribution network, the weak link of the distribution system is found and scientific decision-making basis is provided for the construction and operation management of distribution system.
