摘　　要：针对当前火电厂电动机耗能过大、节能减排效果不足等问题,提出了一种基于永磁性变频调速技术的变频调速装置,新装置通过电机气隙进行控制,进而实现了降低电机的功率消耗的目的。研究结果表明,在加入装置后电机的整体负载开始出现下降,功率消耗降低。在电机上加入变频调速装置后电机的输出功率明显降低,电机的运行寿命得到提升。由此可见,在加入变频调速装置后火电厂发电机的运行功率降低,电机的运行耗能减少,此次研究为该行业提供了参考。Aiming at the current problems of excessive energy consumption and insufficient energy-saving and emission reduction effect of electric motors in thermal power plants,a frequency conversion speed control device based on permanent magnetic frequency conversion speed control technology is proposed,and the new device is controlled through the air gap of the motor,which in turn achieves the purpose of reducing the power consumption of the motor.The results of the study show that the overall load of the motor starts to show a decrease afer the addition of the device and the power consumption is reduced.The output power of the motor is significantly reduced and the operating life of the motor is improved affer the addition of the frequency conversion speed control device to the motor.It can be seen that the operating power of the generator in thermal power plants is reduced after adding the frequency conversion speed control device and the operating energy consumption of the motor is reduced,and this study provides a new idea for research in this direction.
