摘要
目前,普遍采用数字电液调节系统(DEH)对汽轮机组进行控制,以保证机组运行的安全性、可靠性和灵活性。由于原DEH系统的上位机备件已无法买到,为确保机组的安全稳定运行,需要对机组进行DEH上位机的升级改造。对DEH升级改造后的系统调试与准备工作做了介绍和说明,对类似升级过程和系统日常维护具有参考意义。
To ensure safety,reliability and flexibility,steam turbine usually controlled by DEH( digital electro-hydraulic control system). Due to the existing upper computer of DEH is already off the market,the upper computer needs an upgrade. Introduce and explain the post-improvement debugging and preparation,which could be refed by similar project.
