摘　　要：龟石水电站机组技术改造后由原来的4×3 000 kW扩容至4×3 600 kW,通过对待励磁变压器的校核计算,认为不需要更换。论述了对可控硅元件、快速熔断器、起励回路的技术参数的计算、选型和灭磁方案的选择。The installed capacity of Guishi Hydropower Station will become 4~3600kW from original 4x3000kW af- ter technical renovation. According to the results of recheck calculation of excitation transformer, it was not required to replace the excitation system. An introduction was made on the parameter calculation and selection of silicon con- trolled elements, fast fuse, excitation circuit and de-excitation scheme.
