摘要
介绍了核电站选择自励无刷励磁系统的主要原因;分析了无刷励磁系统的构成和功能,重点阐述了其起励和强励的特点,并对转子一点接地保护及其他励磁回路的保护作了应用分析;最后,对灭磁方式及特点进行了说明。研究表明,自励无刷励磁系统适合于大容量的机组,在核电机组中将有着广泛的应用。
This paper discussed the main reason for choosing the self-shunt brushless excitation system in a nuclear power station,introduced the structure and the function of the brushless excitation system,emphasized on the characteristics of flashing excitation and boosting excitation,analyzed the rotor’s one-point earth protection and other protections for excitation circuits,and finally described the de-excitation method and its characteristics.It has been researched that the self-shunt brushless excitation system is suitable for units with high capacity,and therefore has a broad application in nuclear power stations.
