For the suburban districts where reliability is not very necessary, line-link feeders from different buses loop connection mode or three feeders from different buses loop connection mode is suggested.
在可靠性要求不是很高的地区例如城郊等，建议采用架空接线的不同母线出线的环式接线模式或不同母线三回馈线的环式接线模式。
It is shown by theoretical analysis and simulation that this control low, which can applied to semi-close loop and full-close loop system, is simply in design and on-line realization.
理论分析和仿真结果表明：该控制方法设计简单，便于在线实现，并能同时应用于半闭环系统和全闭环系统。
