| Abstract: | Coal mill control system of #6 unit of Huaneng Yangliuqing Power Plant has been put into operation for over ten years,the softwares and hardwares of the control system are getting older and older,and faults occur very frequent.Moreover,the old control system responds slowly and is not convenient to be operated.Face to these problems,it is necessary to upgrade the PLC control system,to change the technological process,to optimize the control logic and to renew the devices.After the development,the coal mill control system operates steadily,and completely accords with the expectant result. |
