摘要
当前永磁同步风力发电机组控制机制多为固定形式,控制的局限较多,导致最终得出的平均运行频率下降,为此提出基于变频器容量的永磁同步风力发电机组控制方法。根据当前测定,先进行坐标变换,采用动态的形式,打破控制局限,设置恒功率因数动态矢量控制机制,然后以此为基础构建基于变频器容量的永磁同步风力发电机组控制模型,采用补偿处理的方式实现机组控制。测试结果表明,针对选定的6:00~8:00、8:30~12:30、13:00~16:00、16:30~20:30以及21:00~24:00五个时段,在变频器容量10 kW和15 kW背景下的平均运行频率均可以达到50 Hz以上。这说明此次设计的永磁同步风力发电机组控制方法更为高效、稳定、安全,在复杂条件下仍可以实现多维控制,灵敏度和针对性较高。
At present,the control mechanism of permanent magnet synchronous wind turbine is mostly fixed form,which has many control limitations,resulting in the decrease of the final average operating frequency.Therefore,the design of permanent magnet synchronous wind turbine control method based on the capacity of frequency converter is proposed.According to the current measurement,coordinate transformation is first carried out,dynamic form is adopted,control limitation is broken,constant power factor dynamic vector control mechanism is set up,based on this,the control model of frequency converter capacity permanent magnet synchronous wind turbine unit is constructed,and compensation processing is adopted to achieve unit control.The test results show that:For the selected five periods of 6:00~8:00,8:30~12:30,13:00~16:00,16:30~20:30 and 21:00~24:00,respectively,under the background of the frequency converter capacity of 10 kW and 15 kW,the final measured average operating frequency can reach more than 50 Hz.It shows that the control method of permanent magnet synchronous wind turbine is more efficient,stable and safe,and can still realize multi-dimensional control under complex conditions,with high sensitivity and pertinence.
