【摘要】 无论是在工业化国家还是在发展中国家 ,供电质量 ,尤其是电压质量正变得日益重要。供电质量低将使产品质量降低 ,严重时还可能导致某些重要的生产过程中断 ,从而造成严重的经济损失。随着越来越多电子设备的使用 ,对电压质量的要求也越来越高。解决供电系统中的谐波及电压突变等问题 ,提高供电质量已迫在眉睫。文章讨论了电能质量的主要问题 ,并介绍了采用基于绝缘栅双极晶体管 ( IGBT)变换器的电能质量调节器装置改善电能质量的情况更多还原

【Abstract】 The quality of electrical energy supply, especially voltage quality, is becoming more and more important in both industrialized and developing countries. An insufficient supply quality can lead to an inadequate quality of products, interruption of important industrial processes and therefore to economic losses. The amount of equipment and industrial processes which are sensitive to insufficient voltage quality, such as harmonics and sags, is increasing. This paper describes the main power quality problems and their solution with IGBT converter based power conditioning equipment.更多还原
