国产化高压变频器在天然气长输管线高陵压气站的应用

Application of Domestic Medium Voltage VFDs in Gaoling Compressor Station of Long Distance Gas Pipeline

近年来,国内天然气长输管线中的大功率高压变频器一直被国外品牌垄断,这对于国内设备制造业的技术发展和能源安全极为不利。为打破这种垄断,在能源局和中石油的大力支持下,上海广电电气(集团)股份有限公司成功研发和生产了首台20 MW级大功率高压变频器。通过对此系列大功率高压变频器的原理、特点和未来发展趋势的论述以及在首个国产化高陵压气站成功应用的介绍,表明国内变频器厂家已具备自主研发和生产大功率高压变频器的能力,从而打破了国外品牌长期垄断的局面,为客户带来非常可观的经济效益和社会效益。

In the long distance gas pipeline,the application of high power medium voltage VFD is monopolized bya few foreign companies recently,which is challenge to the domestic industry and national energy security. With thesupport of national energy administration and China national petroleum corporation,Shanghai Guangdian ElectricGroup Co.,Ltd. successfully developed the first set of 20 MW high power medium voltage VFD to break the monopoly.The principle,characteristics and future development of the series high power medium voltage VFD were discussedand the first application in Gaoling compressor station was introduced and this indicates that the domesticmanufacturer has the ability to develop and produce the high power medium voltage VFD to break the long？termmonopoly by foreign companies,bring considerable economic and social benefit
