摘要
指出目前国内外有载调压都是根据改变变压器两侧线圈的有效变比进行调压,利用此方法进行调压时,输出的电压具有级差,而国内的配电变压器大多是无载调压变压器。因此,要在配电网中实现有载调压,需要更换国内大部分配电变压器。针对以上两点,提出一种基于电力电子技术的新型的有载调压变压器,它结合了传统有载调压方法和交流电压调节器两者的优点,又无需对现有的配电变压器进行更新,是一种很有发展前途的电压调节设备。并利用Matlab仿真软件对其进行仿真,验证了其调压的有效性。
At present, load voltage regulation is conducted by adjusting the transformer＇s effective turns ratio both at home and abroad. By this method, there is level difference in the output voltage. However, most of the domestic distribution transformers are no-load voltage regulating transformers. Therefore, in order to realize load voltage regulation in distribution network, most of domestic distribution transformers need to be changed. To solve the problem, a new load voltage regulating transformer is developed based on power electronic technology. Combined with the advantages of traditional load voltage regulating method and alternating voltage regulator, this load voltage regulating transformer is a promising voltage regulating equipment without updating the present distribution transformer. Its effectiveness of regulating vohage has been tested by using simulation software.
