在分析掌握冷却塔风机主要故障发生机理的基础上,设计了一种基于WinCC组态软件及S7-200 PLC的冷却塔风机重点部位运行状态的监控系统,在设计过程中,运用了PC ACCESS完成S7-200系列PLC与WinCC的通信。生产实践证明,此监测系统明显提高了风机故障监控的可靠性,能够有效地减少风机重大事故的发生,具有良好的推广应用价值。
Based on the analysis of the mechanism of the main failure of the cooling tower fan, a monitoring system based on the WinCC configuration software and the S7-200 PLC cooling fan tower fan operating status was designed. During the design process, PC ACCESS was used to complete S7-200 series PLC and WinCC communication. Production practice has proved that this monitoring system significantly improves the reliability of fan fault monitoring, can effectively reduce the occurrence of major wind turbine accidents, has a good value for the promotion.
