直驱永磁同步风力发电实验系统的构建与实验

摘要

风能是一种清洁的可再生能源,风力发电是风能利用的主要形式,已成为专业教学研究体系的新兴综合性学科.风力发电实验系统采用变速恒频直驱型永磁同步发电机风力发电系统方案构建,系统运用西门子PLC、工业变频器、异步电动机、永磁同步发电机、DSP、BOOST升压及三相逆变配合各类传感器实现设备功能,并用上位PC机组态软件实现系统监控.在此实用的综合平台可便利地开展风力发电实验与测试项目,有助于学生与使用者掌握风电基本系统控制原理与实验测试技术.%Wind energy is a kind of clean and reproducible energy, and wind power generation, the main form of wind energy utilization,has become a new integrated subject in the professional teaching research system. An experimental wind power system is constructed according to the VSCF direct-driven PMSG wind power system scheme,which achieves its equipment function by the Siemens PLC, an industrial converter, an asynchronous motor, the PMSG, DSP, BOOST and three phase inverter and a variety of sensors, and the host PC monitors system by configuration software. Bases on the practical integrated platform, wind power experiment and test project can be developed expediently, which can help students and users to grasp the basic system control principle and the experimental test technology of wind power.
