摘　　要：国内125 MW机组增容改造的同时,大多同步实施调速系统改造,以提高机组调节系统的控制水平。详细介绍了某电厂2台125 MW机组调节系统改造时对各种方案选择进行的分析对比,最终选择上海新华控制工程有限公司高压纯电调方案,改造后,运行情况良好。To most 125 MW units in China, their capacity-increasing retrofits are always performed together with retrofits of speed regulation systems to improve the control level of the unit＇s regulation system. After analyzing and comparing the various schemes for regulation system retrofit of two 125 MW units, the scheme of high pressure pure electro-hydraulic regulation proposed by Shanghai Xinhua Control Engineering Co. , Ltd. was selected. The unit operates normally after the retrofit.
