| 中文摘要 | 根据风力机运行特性及最大风能跟踪原理,基于PSCAD/EMTDC设计了一套由永磁式同步电机与AC-DC-AC脉宽调制(PWM)变流器组成的风电机组软件仿真平台。文中建立了机组各部分模型,并介绍了具体功能的实现。整流侧控制定子q轴电流调节电磁转矩,实现最大风能跟踪;逆变侧实现了对有功、无功的独立控制。通过仿真风电机组在电网低压及不平衡故障下的工作特性,给出了电网异常状况下机组持续运行能力对变流器装置的要求。仿真结果表明,该风电机组不但可以优化风能吸收特性,而且具有良好的低电压穿越特性,在电网不平衡故障下可保持运行,并在故障消除后迅速返回正常工作状态。; According to the characteristics of wind turbine and the maximum power point tracking theory,a simulation platform composed of a permanent magnet synchronous generator and an AC-DC-AC converter is designed,based on PSCAD/EMTDC.Component models are formed and the implementation of system functions is addressed.The magnetic torque is controlled by regulating quadrature stator current to optimize the wind energy absorption.And the inverter regulates real and reactive power independently.The present paper also simulates system performance during various system faults,considering requirements for the conversion system to improve system-fault endurance.Simulations prove that this system can optimize the wind energy absorption according to various wind speeds.It also has appropriate LVRT capability,and great endurance to unbalance faults. |
