摘　　要：发电机组励磁调节系统有完善的控制、保护和限制功能,在进行其保护、限制功能单元的参数设定时要全面、综合考虑发电机变压器组、系统运行方式要求和发变组相关保护定值的配合,以保证励磁系统的安全可靠优化运行。为此对励磁调节系统保护、限制功能单元参数设定应注意的问题进行了分析,并对参数设定原则进行了探讨和说明。The excitation control system of generator sets has perfect control ,protection and limit functions. When setting the parameters of the protection and limit, should synthetically consider the coordination of generator-transformer sets ,system operative specification and the relative protective set points of generatortransformer sets to guarantee the operation of excitation system against safety, reliability and optimization. Therefore, this paper analyzes the considerable problems in setting the parameters of protection and limit function units of excitation system,and discusses the principle of parameters setting.
