Research on a New Method to Achieve LVRT for Wind Farms by Short-circuit Test

摘要

With global warming, more and more people begin to pay close attention to the development of new energy, especially wind power. To promote the healthy development of the wind power industry, countries are required to wind farms with a function of low voltage ride through. The research object of this paper is the capacity for 49.5MW wind farm, using German power system simulation software DIgSILENT/Power Factory to build wind farm model, proposed a new method to achieve LVRT for wind farms by short-circuit test. By comparing the simulation results with the test results, we can verify that the method can achieve the desired requirements.
