摘要
随着电力电子技术的不断发展,特别是大功率晶闸管元件的成功使用,使得晶闸管变流装置的应用日益广泛,然而由于电力电子设备为非线性正弦负载,给电力系统带来了谐波问题,使电网中的谐波电流大大增加,形成电网公害。因而谐波治理就成为普遍关注的技术问题。对相控晶闸管装置谐波源进行了分析,指出了其危害并提出了相应谐波治理的方法。
Along with the unceasing development of electric power electronic technology, specially the successful use of high efficiency thyristor part, Causes the application of the thyristor variable current installment to be widespread day by day. However,because the electric power electronic device is the non- linear sine load, the overtone question is brought to the electrical power system and the harmonic current big increase in the electrical network,form the electrical network environmental damage. Thus the overtone government becomes the universal attentioned technical question. This article has analysed the overtone source of the paraphrase controlled thyristor device to carry, pointed out the harmfulness, and proposed the corresponding overtone government method.
