WDST型调速器为双微机电液调速器 ,DKST型为伺服电机控制的全可编程调速器 ;这两种调速器均为长江控制设备研究所产品 ,已在三门峡水电厂的 7台机组 (单机容量为 5 0MW和 70MW)中运行多年。通过运行实践和现场试验并经对比分析证明 ,这两种类型的调速器均能满足水电厂的运行需要 ;但从高可靠性运行及调整维护工作的要求看 ,以DKST 15 0型调速器更具优越性。
The WDST governor is a dual-microcomputer electro-hydraulic governor and the DKST is a fully programmable governor controlled by a servo motor. Both governors are manufactured by the Changjiang Control Equipment Institute and have been installed in the Sanmenxia Hydropower Plant at 7 Taiwan units (stand-alone capacity of 50MW and 70MW) run for many years. Through the operation practice and field test and the comparative analysis proved that both types of governor can meet the operational requirements of hydropower plants; but from the requirements of high reliability operation and adjustment and maintenance work, the DKST 15 0 speed More advantages of the device.
