变电所主接线可靠性
reliability of substation bus arrangement
biond.ansuo zhu]一ex一an kekoox一ng变电所主接钱可旅性(reliability of substationbus arrangement)衡量变电所各电气回路连接的连续性功能的t度。变电所中各电气回路通过母线而连通.母线故障，将使所连接的各电气回路停止运行;所连接的电气回路故障，也可能累及连接于同一母线的其他无故障回路也停止运行。变电所电气主接线的可靠性水平，视电力系统运行要求而定，同时也受所连接的电气元件特别是断路器的可靠性所制约。 主接线可靠性主要的主接线型式有:单母线接践、单母践分段接践、双母线接线、双母线分段接线、桥形接线(又分内桥与外桥两种)、多角形接线、一个丰断路器接线和双断路器接线等。在连接元件较多时，为了便于断路器检修而不使电气回路停止运行，还可以设旁路母线或迁回母线等。不同型式的主接线有不同的可靠性水平。 电力系统运行对变电所主接线可靠性水平的要求尚无统一的规定。一般而言，处于电力网枢纽位置的变电所，其主接线的故障停运将对电力网运行产生严重的影响，则对其主接线可靠性要求较高;对于处于电力网末端其主接线故障对电力网运行影响不大的变电所，其主接线可靠性要求则较低. 评价主接线可靠性水平的高低一般均从列出“不允许”事件开始，即把那些可能发生的、且一旦发生将导致严重后果的事件列为“不允许”事件。例如，全部电源进线停运，导致主变压器停运，电力网解列等等.然后，根据所选主接线型式及其倒闸操作的可能方式，按一定的规律计算出“不允许”事件发生的概率，停运的持续时间期望值等指标，从而从几种选定的主接线型式中择优.计算这些可靠性指标所用的数学方法有多种，如表格法、路径法、模糊集法、人工智能法等。这些方法各有长短，无本质差别。 计算主接线可靠性的困难在于无可用的墓础数据.断路器的可靠性数据是主接线可靠性计算的关键数据，但可能得到的数据还只是故障发生率，而不是可靠性计算中所需要的故障转移率数据。 不能脱离电力网运行灵活性要求而片面追求主接线可靠性。电力网运行方式的改变，往往是通过变电所主接线的适当操作与切换实现的。不能满足电力网运行灵活性的要求，再可靠的主接线形式，也不会被采用。
