摘　　要：相对广泛采用的以A/D+MCU作为电参数测量方式所设计的无功补偿器,设计了一种以ATT7022+MCU作为电参数测量方式、基于TCR的电动机动态无功补偿器。该控制器能够利用ATT7022计算无功功率,实时获取触发角,并发出触发脉冲控制晶闸管导通,达到无功补偿的目的。实验结果表明所研制的控制器能够动态补偿无功功率,提高电动机运行的功率因数。Compared with prevailing reactive power compensation controller based on A/D and MCU measurement and control, a dynamic controller using. ATT7022 with MCU as electrical parameter measurement is designed based on TCR. AT/7022 is used to calculate the reactive power and get the firing angle. Then the trigger pulse is emitted to control thyristor conduction for the purpose of reactive power compensation. The experiment shows the designed controller could dynamically compensate reactive power and improve the power factor of electric motors.
