摘　　要：台风天气对变频空调的运行带来了挑战:一方面,在空调开启之前,室外风机可能会受到台风的影响,导致其正转或反转,从而可能引起风机启动失败;另一方面,空调运行过程中,突如其来的台风可能会导致室外风机的负载转矩剧烈变化,可能触发速度控制故障并导致停机。针对变频空调在台风天气下室外直流风机的运行问题,提出了一种基于磁链观测器的初始速度检测方法,使系统能够根据初始速度进入对应启动模式;创新了在初始反转条件下的启动控制方法,以提高直流风机的启动成功率;改进了速度环控制器,以增强对台风负载转矩扰动的抵抗力。在由变频空调与台风模拟器组成的实验平台上验证了抗台风控制策略的有效性。Typhoon weather poses challenges to the operation of inverter air conditioners.On one hand,before the air conditioner is turned on,the outdoor fan may be affected by the typhoon,causing it to rotate forward or backward,which could lead to fan startup failure.On the other hand,a sudden typhoon during operation can cause drastic changes in the load torque of the outdoor fan,potentially triggering a speed-control fault and shutdown.For the issue of the operation of the outdoor direct-current(DC)fan of an inverter air conditioner during typhoon weather,an initial speed detection method based on a flux observer is proposed,which allows the system to enter different startup modes according to different initial speeds.An innovative startup control method under initial reverse rotation conditions is developed to improve the success rate of DC fan startups.The speed loop controller is improved to enhance resistance to typhoon load disturbances.The effectiveness of the anti-typhoon control strategy is verified through experiment platform consisting of inverter air conditioner and typhoon simulator.
