摘要
针对用概率统计方法统计低压用户供电可靠性工作量超大的问题,研究如何进行电力系统设备故障模拟及其算法的实现。根据低压系统可靠性模型可建立其可靠性模拟数据库。电力系统故障服从泊松分布,根据各类设备的运行数据即平均故障率,计算出该类设备故障次数的分布曲线。采用随机取样的方法产生本次故障次数以及故障设备编号。该模拟算法简单清晰、易于实现。
In view of the extremely heavy workload of low-voltage power supply reliability statistics using some probabilistic and statistical methods, this paper studies how to carry through the fault simulation of component and facilities and its practical algorithm in power systems. And then the database can be established according to the reliability model of low-voltage power systems. Furthermore, the paper puts forward the method based on Poisson distribution to calculate the distribution curve of facilities fault times according to average fault ratios. Both the fault times and facility ID numbers for this simulation can be obtained using the random sampling method. The presented algorithm is clear to understand and easy to implement.
