摘　　要：提出了一种对复杂辐射状电网进行可靠性评估的方法。该方法先将馈线进行分层,对各层之间的相互影响进行了定量分析。采用替代等值法进行向上等值,串连等值法进行向下等值,并结合了最小路的方法。实例证明了该方法的正确性和实用性。One reliability evaluation method was proposed for complicated redial distribution system. All feeders were classified as to be distinguishable and figure out the effect accurately. The lower feeder was replaced with a simple feeder for the upper one. And then the upper feeder was tandem connected as a simple one to the under layer. The reliability indices were calculated using the minimal path method. The validity and practicability was examined by numerical examples.
