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 veryusefulforpromotionandapplicationinlineswithhighvoltagenearthedistributedpowersources.
