【摘要】 电力系统电磁环境非常恶劣,因而电力系统所应用的电力电子装置的电磁兼容问题越来越受到重视。电能质量调节装置动态电压调节器(DVR)就是一种应用于输配电系统的电力电子装置。文中分析了DVR的电磁干扰源和耦合通道,介绍了DVR避免干扰和抑制干扰的几种方法。这些方法经实践证明是可行和有效的,而且对应用于电力系统中的其他电力电子装置的电磁兼容设计也具有借鉴作用。更多还原

【Abstract】 With the more and more power electronic devices applied to the power system, the EMC problems of these devices are becoming obviously important. The dynamic voltage regulator (DVR), one of the power quality conditioners, is a type of power electronic devices used in power transmission &. distribution system. This paper presents the electromagnetic interference and coupling passage in DVR and several methods to avoid interference and restraining interference are introduced. The technology and methods presented are proved feasible and effective in practical, which are also useful to the electromagnetic compatibility (EMC) design of other power electronic devices as applied in power systems.更多还原
