配电网故障处理关键技术

为了更好地进行配电自动化工程建设,对全负荷开关馈线、全断路器馈线以及负荷开关与断路器混合馈线情况下的配电网故障处理过程分别进行了论述,指出全负荷开关馈线和全断路器馈线各有利弊,负荷开关与断路器组合馈线能够扬长避短并综合两者的优点.分别针对多分段多联络和多供一备网架结构的模式化故障处理步骤给出了建议,并指出只有结合模式化故障处理才能充分发挥上述网架结构的优势,达到提高配电设备利用率的目的.建议采用超级电容器作为配电自动化系统中备用电源的储能手段,并给出了超级电容器容量的计算方法.

Crucial Techniques of Fault Isolation and Restoration for Distribution Systems

In order to better implement distribution automation engineering construction,the fault isolation and restoration process for feeders with load switches,and those with circuit breakers,as well as those with hybrid load switches and circuit breakers are illustrated,respectively.It is pointed out that feeders with load switches and those with circuit breakers both have their own advantages and shortcomings,and hybrid feeders with load switches and circuit breakers can take the advantages and bypass the shortc...
