Design of Intelligent Speed Control System for Hydroelectric Turbine Generator
Hydro generator intelligent speed control system is mainly composed of control core(programmable controller),prime mover,hydro generator,detection sensors,feedback device.The main working principle of the intelligent speed control system is to use the programmable logic controller(PLC)to receive the signals detected by various sensors,such as speed,voltage and switching,etc.,and then send control commands to the executive element(i.e.,the motor)to drive the device to operate normally after the pre-written program is calculated and processed.Using the S7-1200 series PLC manufactured by Siemens as the control core,control programs such as startup,shutdown and emergency shutdown can be realized automatically.Through the design of schematic diagram,system function diagram and PLC control program,a complete set of program is developed to introduce the control scheme of hydro generator intelligent speed control system in detail.
