In rural power grid especially mountainous areas

the problem of low voltage of is more common and prominent

that affects the normal production and life of residents. This paper introduces low voltage governance measures of rural power grid by the compensation capacitor combination completed together with the automatic wide voltage regulator. The compensation capacitor which is arranged on the two sides of voltage regulator

is used to compensate the load reactive power and to enhance the two side voltage.Then

the voltage regulator is used to adjust the voltage to the qualified range. The result of field application shows that this method is effective and feasible. This method has achieved the dual effect of energy saving and low voltage control.
