The invention provides a voltage regulation method, system and device for a power distribution area. The method comprises the following steps: acquiring voltage information of a photovoltaic inverter of each node of the power distribution area according to a preset period; performing voltage qualification rate analysis on the power distribution transformer area by using the voltage qualification interval to generate the voltage qualification rate of the transformer area; identifying the photovoltaic inverter with serious over-high voltage according to the serious over-high voltage threshold value; for the photovoltaic inverter with serious over-high voltage, executing an over-voltage processing flow of a single photovoltaic inverter; aiming at an overvoltage photovoltaic inverter, executing a transformer area overvoltage processing flow; aiming at the low-voltage photovoltaic inverter, executing a transformer area low-voltage processing flow; and after the adjustment is completed, when the voltage information
