ABB公司生产的TURBOTURN汽轮机控制系统用于控制双抽非再热汽轮机的转速和功率,通过控制阀门开度来实现。该控制系统可用SLD自动控制或用“加/减速度或负荷”按钮手动控制汽机转速;可用SLD自动控制或用“加/减速度或负荷”按钮手动控制或用功率控制器控制负荷。甩掉100％负荷后,该控制系统由负荷控制变为速度控制。进行了甩50%,100%额定负荷的试验,结果表明:该控制系统的动态特性满足设计要求。
ABB’s TURBOTURN turbine control system is used to control the speed and power of a double-pumped non-reheat turbine by controlling the valve opening. The control system can be controlled automatically with SLD or with the “Acceleration / Deceleration or Load” button; the SLD can be controlled automatically or manually with the “Acc / Dec or Load” button or with the power controller. After getting rid of 100% load, the control system changes from load control to speed control. The test of 50% and 100% rated load rejection was carried out. The results show that the dynamic characteristics of the control system meet the design requirements.
