交流灭磁技术在大型抽水蓄能机组中的应用

Application of AC de-excitation technology to large-scale pumped storage power generator

交流灭磁技术在抽水蓄能机组中的应用是一个较新的课题。简要说明交流灭磁技术的特点,详细介绍德国SIEMENS公司生产的3WN16型交流灭磁开关,以及由交流灭磁开关和线性灭磁电阻跨接器组成的SIEMENS交流灭磁系统及其在广州抽水蓄能电厂B厂4×300MW机组中的应用情况,最后进一步明确交流灭磁技术的应用前景。

The study and application of AC de-excitation technology in pumped storage po wer station is a quite new subject.This paper briefly introduces the features o f AC de-excitation technology,the SIEMENS3WN16AC de-excitation circuit bre aker in de-tail,and the SIEMENS AC de-excitation system composed of AC de-ex citation circuit breaker and linear de-excitation resistance crowbar.Based on its operation in Guangzhou Pumped Storage Power Station,it affirms the applica tion foreground of AC de-excitation technology.
