复杂电气系统可靠性的数字仿真

针对复杂电气系统的可靠性问题进行了数字仿真研究。提出了以网络最小路为基础的直接数字仿真方法，它的特点在于不仅可以求出系统可靠性的点估计值，还可以得到统计值的分布函数。这种方法直接根据系统的可靠性网络，建立各最小路失效时间的随机样本，并获得系统的失效时间样本，经过Ｎ次仿真后进一步求出系统的指标。另外，这种直接数字仿真方法概念清楚，仿真过程容易实现

The Digital Simulation of the Reliability of Complex Electrical System

The digital simulation of the reliability of complex electrical system is made, and the direct simulation method on based network minimal paths is presented, character of which lies in the fact that it can not only calculate point estimating value of the reliability of system, but also obtain the distributed function of statistics. The method sets up the random samples of the failure time of every minimal path and acquires the sample of the failure time of system according to the reliability network of system. The reliability index of system may be calculated through N simulations. Therefore, the concept of this method is clear, and the realization of simulation process is easy.
