Description

technical field [0001] The invention relates to the technical field of wind power generation modeling, in particular to a modular full-power wind turbine wind farm simulation system, simulation method and equipment. Background technique [0002] With the recent rapid development of clean energy represented by wind power and photovoltaic power generation, the power system is undergoing a transformation from centralized power generation to distributed power generation systems. The continuous improvement of the domestic energy demand and the sharp increase in the demand for energy, the traditional energy will not be able to meet the growing energy demand, so vigorously developing new energy including wind power will be an important development direction in the next step. [0003] Compared with double-fed wind turbines, full-power wind turbines have the characteristics of high efficiency, high power density, and high reliability. Back-to-back converters are used to feed the elec...
