中文摘要：
为了使风电机组/风电场与电网之间能够和谐稳定高效的运行,笔者在通过对电网电压骤升时风电机组的暂态分析,提出了采用静止同步补偿器STATCOM实现双馈风电机组高电压穿越的方案。在电网电压骤升的情况下,通过STATCOM控制策略吸收电网容性无功并补偿感性无功支撑系统运行不脱网。在MATLAB/Simulink仿真平台上搭建仿真模型并进行仿真,仿真结果表明,当电网电压骤升时STATCOM不仅能确保风电机组不脱网运行还能及时向故障电网提供一定的感性无功,协助电网电压快速恢复。
英文摘要：
In order to efficient and stable operation of the wind turbine generators（wind farms）integrated with power system, this paper comes up with the high voltage ride-through of DFIG based on STATCOM by analyzing wind generators transient on the grid voltage swells. When the grid voltages swells, the control system of STAT- COM absorb grid capacitive reactive power and inductive reactive power compensation to keep the DFIG continuous working. A simulation model is established in MATLAB/Simulink, analysis the results prove the STATCOM not only insure wind generators keep working but also inductive reactive power for help grid fast recovery.
