兆瓦级双馈风力发电系统低电压穿越实现措施及效果验证
|
摘要
针对双馈风力发电系统在电网电压发生跌落故障时影响风电机组稳定运行甚至产生解列这一情况,采用了基于动态刹车电阻DBR回路方案来解决这一技术难题。对WT2000型兆瓦级双馈风力发电系统低电压穿越功能模块进行了介绍,利用Matlab/Simulink进行了系统仿真,并在WT2000型兆瓦级双馈风力发电系统上进行了实地测量。结果表明,在电网电压发生跌落时,能在短时间内响应故障启动泄容装置,使系统维持安全工作状态,符合GB/T 19963-2011《风电场接入电力系统技术规定》国家标准。
The stable operation of the wind turbines of the doubly fed wind power generation(DFIG)system can be affected when the grid voltage drop occurs.On the basis of previous studies' results,we propose a circuit based on the dynamic braking resistor(DBR)to solve the low voltage ride-through(LVRT)problem.We first introduce the low voltage ride through function module of WT2000 MW class DFIG system.Then we carry out system simulations by using the Matlab/Simulink,and perform field measurements on a WT2000 MW class DFIG system.The results show that the system can respond to the fault and activate discharge devices in short time so as to maintain the safe working condition when the voltage drop occurs.The proposal conforms to the national standard of GB/T 19963-2011"Technical Requirements of Wind Farm Access Power System".
