摘　　要：探讨了几种具有相同主设备参数的垃圾发电厂电气主接线方式的合理性。通过短路电流计算,分析了断路器额定短路开断电流、额定短路关合电流、直流分量等技术性参数,并分析了各电气主接线方式的经济性。在综合考虑技术性和经济性的基础上,推荐一种较合理的接线方式:选择直轴超瞬态电抗较大的发电机,发电机出口选用普通真空断路器,厂用电部分采用分支结构。The paper discusses reasonability of several main electrical connection modes with the same main equipment param-eters of municipal solid waste incineration power plants. By means of short-circuit current calculaparameters including rated short-circuit breaking current, rated short-circuit closing current, DC components, and so on as well as economy of each main electrical connection mod.. On the basis of comprehensively considomy, it recommends a kind of rational connection mode which is to choose the generator with larger direct-axis subtransient reactance, use ordinary vacuum circuit breaker for the generator exit and adopt branch
