全功率变频风力发电机组惯性响应控制
|
摘要
针对频率波动时全功率变频风电机组不能对电网提供频率支撑的问题,文章将虚拟惯性调节和下垂调节相结合,利用全功率变频风电机组的惯性控制技术参与电网调频,将风机有功出力设定在低于最大功率追踪,使其有足够空间进行有功调节,以及惯性环节结束后发电机转子转速快速恢复。仿真结果证明了文章控制策略的有效性。
The permanent magnetic synchronous wind turbine connects to the power grid through the full power converter, which could transfer the alternating current into direct current and into alternating current. However the wind turbine is decoupled with grid by the power converter, and can not provide frequency support. A permanent magnetic synchronous wind turbine model is presented and used to show the impact of wind speed transients on inertial response in a variable system load. virtual inertia control and droop control have been proposed. In the module inertial gain and droop gain Setting, this paper according to the mathematical model maximum power tracking(MPPT) got the relationship between the active power with generator rotor speed, then then gain value have been figured out. This paper innovation is that the wind turbine output power is set in a certain proportion with the output of MPPT, which could make it have enough space for active regulation and recovering the generator rotor speed quickly after inertial control.
