| Abstract: | Application of PLC in technological innovation of the feeding coal system in the thermoelectric power station is expounded, and gives the hardware component and the design method of control software. The new system settled many problems in the traditional system controlled by relay and contact device, improved the anti - disturbance ability of feeding coal system, reduced the failure rate. It makes the operation security and reliability, and realizes the all right cycle of economic efficiency and the social efficiency. |
| Keywords: | PLC feeding coal system order control |
