STUDIES ON START UP CONTROL STRATEGY OF WIND TURBINES BASED ON MAXIMUM TORQUE

针对变速恒频风力发电机组的开机控制问题,提出一种在不同风况下可实现机组快速启动的最大转矩开机控制策略,并通过理论分析与仿真实验对控制规律进行简化。仿真实验表明,最大转矩开机控制策略能满足机组快速启动的控制目标,线性化后的控制规律易于工程实现,并适用于风速在较大范围变化时的快速开机控制。

Considering the start up control problem of VSCF wind turbines, a strategy based on maximum torque was devised, which can realize generator speed＇ s rising and synchronization quickly in different wind conditions, and simplify the control strategy by the theoretical analysis and the simulation experiments. The simulation results showed that the control strategy can meet the control target of starting up quickly, it is easy to engineering realization and is also appropriate for starting up quickly when the wind speed changes in wide range.
