摘要
结合水能分布特性,运用邻接终点矩阵法,分析了电气主接线可靠性指标和断路器的故障率模型。同时对电气主接线可靠性进行了灵敏度分析,研究结果表明:改变元件的可靠性参数对系统的可靠性有显著的影响。并以沟滩皮水电站为例,分析验证了上述方法的有效性和正确性。
The bus arrangements component reliability indices formula and the circuit breakers failure rate model are studied with applying adjacent terminal matrix combined with water distribution characteristics in this paper. And base on this,sensitivity of component reliability indices are analyzed. Results show that the influence on changing reliability parameters is significant for system reliability indices. The above validity and accuracy mentioned model and method is verified by Goutanpi hydropower station example.
