The invention discloses a large-scale photovoltaic power station reactive voltage sequential coordination control technology, and belongs to the technical field of automation of a power system. Reactive voltage triple regulation and control systems are established according to priorities, the previous two reactive adjustment systems, based on voltages of the output end of each photovoltaic generating unit, regulate and control output reactive power, including a reactive investment capability of each photovoltaic generating unit and coupling reactive investment capabilities between the generating units, so as to stablize voltages of each unit end and realize an equalization state, and the third reactive adjustment system, based on a static var generator (SVG), makes up a deficiency of reactive output of a photovoltaic power station itself. According to the invention, voltage level of a grid-connected point can be improved, consistency of end voltages of each photovoltaic generating unit is maintained, the capability of resisting external interference is enhanced, the safety and stability of network operation of a large-scale concentrated photovoltaic power station are improved, and at the same time, investment of the SVG is reduced.
