Abstract
Aiming at the problems of complicated maintenance,no automatic reset to the working state,no timing function,no human-machine interface,no remote control function and no automatic sewage discharge function of the gas tank of the original medium-pressure compressor air system in Yantan Hydropower Station,the upgrading and transformation have been carried out.The author introduces the transformation in detail from eight aspects:the reason of equipment upgrading and transformation,the first application of domestic PLC with completely independent intellectual property rights,the realization of simple operation of gas tank maintenance,the optimization and implementation of redundant control function,the addition of time synchronization,communication with monitoring,remote control and new functions of automatic sewage discharge of gas tank,and expounds the problems encountered in the transformation process and the solutions.The results show that the transformation has achieved good results,the equipment runs reliably,and the labor intensity of operation and maintenance personnel is reduced.The transformation experience can provide reference for the subsequent transformation of low-pressure compressor air system and similar auxiliary equipment.关键词
