摘要:: 风电市场已然是竞价上网的平价时代，在市场大环境的影响下，电机的精准设计成为了亟待攻克的热点。在双馈风力发电机的设计过程中，转子电流值计算的精确性不仅关乎电机成本问题，也对转子侧变流器的选择有重要影响。本文针对双馈风力发电机设计过程中转子电流的精确计算，提出了一种基于集肤效应及有限元仿真的解析及仿真方法。该方法可在误差允许范围内精确计算各工况下的转子电流值，为后续的精准化优化设计及转子侧控制策略的制定提供一定的指导作用，并通过与试验值对比，验证了其可行性。

Abstract:: The wind power market has become an era of parity for bidding on the grid, and under the influence of the market environment, the precise design of generators has become a hot spot to be overcome. In the design process of doubly fed wind turbine, the accuracy of rotor current calculation is not only related to the motor cost, but also has an important impact on the selection of rotor side converter. This paper proposed a method based on skin effect and finite element simulation for the accurate calculation of rotor current in the design process of doubly fed wind turbine. This method can accurately calculate the rotor current values under various working conditions within the allowable error range, which provides certain guidance for the subsequent accurate optimization design and the formulation of rotor side control strategy, and verifies its feasibility by comparing with the test value.
