Title Distribution network fault factor correlation analysis and research
Abstract
Safe and reliable operation of the distribution network is the key to social development，therefore, the distribution network security analysis and reliability assessment is very important.From the line, substation and grid structure three aspects of the impact of the distribution network safe operation of internal factors and external factors studied the mechanism of distribution network failure.The main internal factors affect the reliability of the system.So this paper studies the principles and methods of distribution grid reliability analysis, assess the reliability of the distribution network based on the dual use of Monte Carlo sampling method,use the matlab to prepare the corresponding program,analyze the main feeder F4 and F1,F2 of IEEE RBTS BUS6 test system,to verify that the algorithm is correct and effective.Again whether the standby power distribution system, the availability of spare transformers, circuit breakers whether these types of different situations and reliable operation of the reliability analysis and comparison, measures to improve the reliability of the distribution network.
