Introduction of the Direct Drive Wind Power Generation System

Abstract:

With the development of economy, the energy demand is becoming bigger and bigger, the development of wind energy is one of the main ways to solve energy crisis. In terms of energy utilization, high power wind power connected to the grid is currently one of the most effective ways of wind energy utilization. The wind power generation system connected to the grid plays the role of the changing wind energy into mechanical energy by wind turbines, and then converts mechanical energy into electrical energy by a generator. Because CSCF wind turbine works with the gearbox, which is low efficiency, noise and mechanical loss. And it has not been able to meet the needs of the times. Therefore, the direct drive wind power technology capable of tracking the maximal power point of wind power at rated wind speed has become one of the hot spots in the present research. This paper introduces the converter of the direct drive wind power system and analyzes the working principle of the direct driven permanent magnet synchronous wind power system.
