摘要
随着风力发电的快速发展,双馈式发电机的市场占有率越来越高。针对双馈式发电机的工作和结构特点,分析求解出电机发生断条故障时的易解数学模型。使用该模型在Simulink环境下进行仿真,通过分析断条故障特征,提取故障信号,对该模型进行了验证。该模型仿真结果与理论分析相吻合,有助于风力发电机的实时故障监测。
With the rapid development of wind power generation, the high market share of doubly-fed generators is getting. According to the characteristics in the work and the structure of the doubly-fed generator, this paper analyzes mathematical model which is easy to solve for the generator rotor broken-bar fault, makes a simulation based on Simulink, and extracts fault signals by analyzing the characteristics of the rotor broken-bar fault. The results show the feasibility of the model and coincide with theoretical analysis, contributing to the real-time fault monitoring of the wind generator.
