| 摘 要： | 提出利用静止同步补偿器(static synchronous compensator,STATCOM)快速补偿无功功率以增强双馈式风电机组和直驱式风电机组的低电压穿越能力.首先阐述了风电机组的动态模型,然后给出了STATCOM控制模型,最后将STATCOM装置应用到合风电场的电力系统中,比较加装STATCOM前后母线56和母线12的电压以及风电机组输出功率的变化情况.仿真结果表明,STATCOM能有效地帮助风电机组在电网发生故障后恢复机端电压和故障点电压,并防止风电机组输出功率振荡,使风电场在故障发生后能保持连续运行,增强了风电机组的低电压穿越能力. |

| Abstract: | It is proposed to enhance LVRT of double fed wind turbine and direct-drive wind turbine by fast compensation reactive power of static synchronous compensator(STATCOM).The paper first expounds dynamic model of wind power units,then it introduces STATCOM control model and finally applies STATCOM in power system with wind farm and compares voltages and output power of bus 56 and bus 12 before and after installation of STATCOM.The simulation result shows that STATCOM can help recover generator terminal voltage and fault point voltage after grid faults and prevent oscillation of wind power units so that wind farm can continue operating after fault and LVRT can be enhanced. |
| Keywords: | double fed wind power unit direct-drive wind power unit LVRT STATCOM wind farm |
