一、概况乌溪江水电厂为高水头引流式电站,装有混流式机组42500千瓦四台。调速器采用东方电机厂生产的DT-100型电液调速器,主要技术参数如下: 机械柜型号DT-100,主配压伐直径100毫米;最大工作油压25kg/cm~2; 电气柜型号ZDT,频率调整范围42～52赫,残留不平衡度0～10％。电液调速器由电气部分和机械部分组成。电气部分由测频回路、信号综合回路、相敏整流回路、电子管放大器、反馈及控制部分等组成;机械部分主要为承担电气、机械连接的电液转换器及液压放大、功率传输等部分。其原理方框图见图一。
I. Overview WuXiJiang Hydropower Plant is a high-head drainage station, equipped with four mixed-flow units of 42,500 kilowatts. The governor adopts the DT-100 type electro-hydraulic governor produced by Dongfang Electric Machinery Factory. The main technical parameters are as follows: The mechanical cabinet type DT-100, the main compaction cutting diameter 100mm; The maximum working pressure 25kg / cm ~ 2; Electric Cabinet model ZDT, the frequency adjustment range of 42 ~ 52 He, residual imbalance of 0 to 10%. Electro-hydraulic governor by the electrical and mechanical parts. The electrical part is composed of frequency measurement loop, signal synthesis loop, phase sensitive rectification loop, tube amplifier, feedback and control part, etc .; the mechanical part is mainly responsible for electrical and mechanical connection of electro-hydraulic converter and hydraulic amplification, power transmission and other parts. The principle of block diagram shown in Figure one.
