摘要
发电机的灭磁方式正在由依靠断路器弧压灭磁的传统耗能型向以断路器和跨接器组成的移能型灭磁方式转移,同时,交流灭磁技术在引进机组中也获得了应用,其优异性能引起了国内励磁界的广泛关注。德国Siemens公司为广州蓄能水电厂二期工程制造的励磁装置,其设计即采用交流灭磁方式,由交流断路器和跨接器实现灭磁,并最终导致取消直流灭磁断路器,具有明显的经济性和实用性,代表了当今灭磁技术的研究和发展方向。
The de-excitation method for generators is changing from the traditional energy-consuming circuit breaker arc voltage de-excitation to the circuit breaker and jumper-based energy-transfer de-excitation. The AC de-excitation technology is adopted in some of the imported units, and it draws much concern of domestic technical personnel. The excitation system of Guangzhou Pumped Storage Power Station Phase Ⅱ, made by Siemens Company, is designed with the AC de-excitation method and de excitation is realized by means of AC circuit breakers and jumpers, which results in the cancellation of DC de-excitation circuit breaker. Its significant economic efficiency and practicability represent the trend of the research and development of de excitation technology.
