摘　　要：本文对小水电出口附近存在电压偏高问题进行了分析,根据单机无穷大系统的特点提出了一种既能治理丰水期线路小水电出口附近电压偏高,又能治理枯水期线路后段电压偏低的方法,并对其进行分析,最后通过仿真、挂网运行验证这种治理方法的可行性。结果表明,文中提出采用馈线自动调压设备反向调压的治理方法不仅投资小见效快,而且简单实用、可靠性高,馈线自动调压设备在含有小水电乃至其他含有分布式电源出口附近电压偏高的线路都非常具有推广应用价值。In this paper,the problem of high voltage in the distribution network with small hydropoweris analyzed.According to the characteristics of the single infinite system,a method is proposed that can not only control the high voltage near the exit of small hydropower in the wet season,but also control the low voltage at the rear end of the dry period.Finally,the feasibility of this method is verified by simulation and network operation.It is shown by the result that the automatic feeder voltage regulator reverse voltage regulation method is not only effective,but also simple,practical and reliable.Automatic feeder voltage regulatoris very useful for promotion and application in lines with high voltage near the distributed power sources.
