电网谐波控制优化研究

On Optimization of Power Net Harmonic Control

IGBT等高速全控电力电子元器件在PWM整流器装置上的使用,在供电系统中会产生较大的谐波干扰。谐波产生对控制系统通讯和设备本身造成严重损害,尤其是电网中的高次谐波,对连接在电网上的电气设备都会带来多余的损耗,甚至会对电源模块、滤波器、阻容吸收模块和无功功率补偿装置等造成损坏,所以谐波治理成为企业降低成本、保证设备稳定运行的一个重要环节。

Application of IGBT and high speed full control electronic parts to PWM rectifier device induces a mass of har -monic wave on the power net and disturbance , heavily harmful to the communication of control system and equipment , even for power supply module , filter, RC absorb module and SVC equipment .So the treatment of harmonic wave becomes the key link for reducing the cost of enterprise production and warranty of production equipment running stably .
