摘要
在功能方面,发电机励磁系统设置了完善的励磁电流、发电机电压和发电机过励等有关的限制保护单位等。发变组保护则主要起到保护的作用,设置了励磁绕组过负荷以及发电机过电压等。为促进机组完好运行,需要对两者的参数数值进行整定,以机组的设备参数、运行的方式和条件作为基础,最终对励磁调节器以及发变组的参数进行优化。因此,将主要从励磁系统与发变组保护的基本概念以及发变组保护与励磁系统配合问题的研究这两个方面进行阐述。为优化两者间的配合,保障机组良好运行提供合理的参考意见。
In the aspect of function, the generator excitation system is set up to improve the excitation current, generator voltage and generator over excitation and other related units to limit the protection. The generator transformer protection is mainly used to protect the system, and the excitation winding overload and generator overvohage are set up. In order to promote the unit to perform well, need pararneters on both numerical setting, the equipment parameters, unit operation mode and conditions as the basis for the final excitation regulator and optimize the parameters of the generator. Therefore, this paper will focus on the basic concepts of the excitation system and the generator transformer protection and the research on the coordination between the generator transformer group protection and the excitation system in two aspects. In order to optimize the cooperation between the two ones, providing a reasonable reference to ensure the good operation of the unit.
