摘要:风电机组功率特性现场测试存在效率低、条件要求高、结果不准确等问题,已成为当前行业关注的热点。为有效解决风电机组功率特性工程测试工作中存在的效率偏低等问题,提出一种基于能量传递模型的功率特性测试方法。以永磁直驱机组为研究对象,围绕永磁直驱机组能量捕捉、传递、转化过程,结合机组风能捕捉系数与桨距角、叶尖速比之间的关系,从机理角度进行定量分析,构建典型机组的能量传递模型,对比实测数据进行调整;在同类机组上进行应用验证,取得了预期的效果,验证了该方法的有效性,研究结果具有重要参考意义。
Abstract:Several problems at the power characteristics of wind turbine site test such as low efficiency, harsh conditions and unfaithful results are becoming focus in the industry. A method with energy transmitted model at PMSG-based wind turbines (WT) was proposed, which researches on process of energy capture, transmitting, conversion with relationship of wind energy capture and pitch angle, blade tip speed ratio by quantitative analysis to construct energy transmitted model of typical wind turbine. The model was verified by similar WT in same wind farm after being modulated by comparing site measured data with model output data. The energy transmitted model has become the theoretical foundation to support WT's power performance characteristic.
