海洋钻井平台主空压机控制系统改造
|
摘要
为解决"勘探四号"半潜式海洋钻井平台主空压机控制设备老化、控制设备备件断货、故障率高和自动化程度较低等问题,探讨了主空压机的工艺流程、控制设备组成、控制系统要求和提高控制系统可靠性的方法,并基于西门子S7-200 PLC和MCGS触摸屏进行程序设计和编程,对原控制系统进行改造,有效地解决了空压机的原有故障,节约了空压机整机换新的成本,可为类似空压机的故障解决和控制系统改造及设计提供参考。
In order to solve the problem of control equipment aging,out of store,low degree of automation and high failure rate of center air compressor of semi-submersible platform Kan Tan Ⅳ,the process flow,control equipment component,control system requirement and the method of improving control system′s stability were introduced,and programming based on the SIEMENS S7-200 and MCGS configuration interface for this center air compressor was designed. The original control system was reformed,the original fault of this air compressor was effectively solved,and the cost of renewing whole air compressor was saved. It can offer a reference for troubleshooting and control system reform and design of similar air compressor.
