针对传统备自投在发展中遇到的一些问题,提出构建区域备自投系统的构想.论述了有源同期并列非同期问题.备自投动作成功时运行设备存在过载问题和串供多个变电站时线路备自投无法保证所有变电站不失压问题、母线故障备自投误动以及备自投合风电时等情况,并根据区域备自投系统构想提出改进建议,分析表明:所述几种情况均能得到有效解决,区域备自投构想对备自投未来的发展方向有一定指导意义.%Aiming at the problems found during the development of the traditional power supply automatic switching device, an idea of building a regional power supply automatic switching device system is conceived. The paper states the problems of the non-synchronous parallel of active synchronous parallel, over loading of operating device after power supply automatic switching device succeeds, and that power supply automatic switching device can not ensure that series of supplying substations do not lose voltage, power supply automatic switching device operates mistakenly when the fault of bus happens and the situation of power supply automatic switching device when containing the wind power. Then some suggestions of improvement are proposed according to the idea. Results show that problems all above could be resolved successfully and the idea of building a regional power supply automatic switching device system can guide the development of the power supply automatic switching device in the future.This work is supported by National Natural Science Foundation of China (No. 50767003).
