摘　　要：通过建立各种供电模式年费用数学模型,推论出合理的农村电网供电模式,并对现有供电模式改造的可行性进行经济论证,得出不同负荷密度下,应改造的现有农村电网的最小运行年限。建议在新建农村电网中,优先考虑110/10kV供电模式,适当控制35/10kV变电所的发展,并试点应用110/20kV供电模式。This paper establishes the mathematic models of the annual expenses of variable power supply modes, infers the reasonable power supply modes of rural network, then gives economical argumentations for the feasibility of the reconstruction of existing power supply modes, and educes the minimum operating years of existing rural power network under variable load densities. It is suggested that in new rural power network, 1 10/10kV supply mode is the top-priority, 35/10kV substations should be controlled properly, and 110/20kV supply mode can be used as experimental applications.
