摘要
随着风电并网规模不断增大,主动配电网的动态电压稳定性和动态供电质量问题日益突出。永磁直驱风机的动态特性与电网交互作用对电力系统稳定存在重要影响,风电场中越来越多的开关器件给风机并网控制策略的验证带来了新的挑战。基于RT-LAB平台采用FPGA实时仿真器,搭建了永磁直驱风机的硬件在环仿真平台,实现了永磁直驱风机的亚微秒步长实时仿真,为直驱风机的控制策略验证及优化提供了一种快速有效的验证方法。仿真结果证明了小步长硬件在环仿真方法的有效性。
With the increasing scale of new energy grid,active power distribution network dynamic voltage stability and dynamic power supply quality control and other issues become increasingly prominent,the interaction between the dynamic characteristics of the permanent magnet direct-drive permanent magnet synchronous generator and the power grid has important influence on the stability of the power system.More and more switching devices in the wind farm have brought new challenges to the control strategy of the fan.Based on the RT-LAB platform,this paper implements the real-time simulation of the sub-microsecond step of the permanent magnet direct drive fan by using FPGA real-time simulator,which provides a fast and effective verification method for the verification and optimization of direct drive fans.Finally,the simulation results demonstrate the effectiveness of the small step hardware in-loop simulation method.
