In recent years, the interest in the use of regenerative energies has increased considerably, which helped to alleviate the energy crisis and to protect the environment. However, the over-rapid development of wind power also leads to some problems in China, for example, several large-scale off-grid accidents caused by quality problems of wind turbines. Since converter is a core component of wind power turbine, improving converter control strategy can prevent such accidents. Therefore, this paper explores and analyzes the converter control strategy and its influences on power grid and wind turbines, including grid power and voltage fluctuation, small signal stability, transient stability, LVRT (low voltage ride through), shaft damping, and shaft transient stress. This paper attempts to determine the content and method for quality inspection of converter and proposes a test platform to carry out flexible, efficient and reliable quality test.
