| Abstract: | The application of programmable logic controller (PLC)in water supply system of thermal power plant is introduced. The LSS software is used to compile the PLC control program. The controller acquires the state signals of various devices, optimizes the control of eight pump groups, communicates with the supervisory computer, sequentially controls the on or off of pump motors and realizes fault alarm. The use of PLC can save not only the electric energy but also the water resource. |
