Title:
REACTIVE POWER COMPENSATION METHOD AND APPARATUS, PHOTOVOLTAIC GRID-CONNECTED INVERTER, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/006681
Kind Code:
A1
Abstract:
A reactive power compensation method and apparatus, a photovoltaic grid-connected inverter, and a computer storage medium. The method comprises: when the photovoltaic grid-connected inverter is in an active power output mode, acquiring first output state information of a photovoltaic cell (101); determining whether the first output state information satisfies a first switching condition (102); when the first output state information satisfies the first switching condition, switching the photovoltaic grid-connected inverter from the active power output mode to a reactive power compensation mode (103); when the photovoltaic grid-connected inverter is in the reactive power compensation mode, acquiring second output state information of the photovoltaic cell (104); determining whether the second output state information satisfies a second switching condition (105); and when the second output state information satisfies the second switching condition, switching the photovoltaic grid-connected inverter from the reactive power compensation mode to the active power output mode (106).
