摘　　要：无功功率的损失和谐波干扰是电网污染的最主要原因。电力系统的谐波干扰会使电能的生产、传输和利用效率降低,使电气设备过热,产生振动和噪声,并使绝缘老化,使用寿命缩短,谐波还会引起继电保护和自动装置误动作,使电能计量出现混乱。针对谐波对通信设备和电子设备产生严重干扰问题,提出了一种非线性放大器装置,系统采用STM32F103单片机作为核心处理器,设计了五种非线性失真放大电路:无失真电路、顶部失真电路、底部失真电路、双向失真电路、交越失真电路,以确保相关设备的安全运行。The loss of reactive power and harmonic interference are the main causes of power grid pollution.The harmonic interference of power system will reduce the efficiency of production,transmission and utilization of electric energy,overheat the electrical equipment,produce vibration and noise,aging the insulation,shorten the service life,and cause misoperation of relay protection and automatic devices,resulting in confusion of electric energy measurement.Aiming at the serious interference problem of harmonic to communication equipment and electronic equipment,this paper proposes a nonlinear amplifier device,which uses STM32F103 as the core processor,and designs five kinds of distortion circuitsno distortion circuit,top distortion circuit,bottom distortion circuit,bidirectional distortion circuit,crossover distortion circuit,so as to ensure the safe operation of related equipment.
