Photovoltaic power station reactive voltage control method

The invention discloses a photovoltaic power station reactive voltage control method, and belongs to the technical field of electric power system control. According to the photovoltaic power station reactive voltage control method, a reactive distribution method of a photovoltaic power station is provided according to a photovoltaic power station reactive set value and photovoltaic power station grid connection point bus voltage. Reactive capability of a photovoltaic inverter and rapidity of adjustment of a dynamic reactive power compensation device can be both fully utilized so that rapid and continuous reactive coordinated control of the photovoltaic inverter and the dynamic reactive power compensation device can be actually realized, and thus the reactive voltage requirement of a power grid for the photovoltaic power station can be met.
