Abstract

The invention provides a software and hardware integrated new energy power generation automatic grid-connected switch control system and method, and belongs to the technical field of grid-connected switch control. The software and hardware integrated new energy power generation automatic grid-connected switch control system comprise a hardware grid-connected control part and a software grid-connected control part. The software and hardware integrated new energy power generation automatic grid-connected switch control system has the beneficial effects that grid-connected control of a new energypower generation system is effectively achieved under the condition of three-phase unbalance and harmonic of a three-phase power grid voltage.

Description

technical field [0001] The invention relates to the technical field of grid-connected switch control, in particular to an automatic grid-connected switch control system and method combining software and hardware for new energy power generation. Background technique [0002] With the development of the world and China's economy, the consumption of energy will increase sharply, so that our country will face the double pressure of environment and resources for a long time in the future. The academic and industrial circles will focus on clean and renewable solar energy and wind energy. A large number of technical research and relevant national policies are promoting the development and utilization of these energy sources. New energy power generation has the characteristics of great intermittency and uncontrollability. The large-scale centralized connection of wind farms to the grid mainly includes direct grid connection, step-down grid connection, quasi-synchronous grid connecti...
