摘要
文章主要介绍电厂给水泵小汽机TSI监视系统的组成,提出一种能够更好避免汽机振动误动和拒动的具体方案,提高了小汽机轴承振动保护可靠性。同时,对给水泵小汽机的交流、直流润滑油泵保护进行了优化,增强了给水泵小汽机在应对DCS系统故障时保证润滑油系统运行正常的能力。
This paper mainly introduces the composition of feed water pump micro-turbine's TSI monitor system in power plant,puts forward a concrete solution which can better avoid the act-error or act-refused in turbine vibration protection, and improves the reliability of the turbine vibration protection. At the same time, the protection of AC and DC lubricating oil pump of the turbine is further optimized, which enhances the ability of feed water pump micro-turbine to ensure the normal operation of lubricating oil system when dealing with DCS system failure.
