摘要
风力机的并网控制要求安全可靠.它是在风动力作用下,由计算机控制软并网,然后主接触延时接通,实现正常发电运行.根据风资源的不稳定特点,为有效地利用风能并提高风力机效率,可采取不同的并网控制方式.
The control of cutting-in network in wind turbine must be safe and reliable. Under the cut-in wind speed, the computer controls soft-cut-in network while the main contactor is delayed in action, then the wind turbine is getting into normal performance as generator. According to the distinguishing feature of unstable wind speed, the different control methods of cutting-in network can be used in order to utilize wind energy more effectively i. e. to improve wind turbine efficiency.
