摘 要: 配电网中主馈线分段开关的设置是提高配电网可靠性指标的途径之一 ,而主馈线的首末两端都设置分段开关对提高系统的可靠性肯定有帮助 ,但从经济的角度却未必划算。利用可靠性理论 ,在综合考虑系统投资效益与可靠性效益的基础上 ,通过分析每段主馈线末端分段开关对系统可靠性的影响 ,给出了在每段主馈线末端是否应该设置分段开关的判据 ,并以RBTS5的 1、2两条馈线为例验证了判据的有效性。 It is one of the effective way to improve the reliability indices that to mount the disconnect switches on the main feeder.And it is helpful to improve the reliability that to set disconnect switches on the both end of the main feeder.However,it isn′t worth to do so for the economic reason,a criterion about the disconnect switch should be mounted or not,which combining the investment with the reliability benefit,is presented in this paper by analyzing the impaction of the reliability of the switch.In the end,using the criterion to reconfigure the 1 st and the 2 nd feeders of the RBTS5.
