600MW直接空冷机组轴振动保护系统的改进

Improvement of Shaft Vibration Protecting System for 600 MW Direct Air-cooling Turbine Units

为了解决国产600 MW直接空冷机组在汽轮机轴振动测量及保护方面存在的问题,对轴振动传感器进行了安装位置、保护逻辑等方面的改进,提高了轴振动测量的准确性及汽轮机轴振动保护的可靠性,也为国产600 MW直接空冷机组相关问题的解决,提供了一些可借鉴的经验。

To solve the problem in measurement and protection of shaft vibration of turbine units for the domestic 600 MW direct air-cooling turbine units, this paper provided the improvement in the location and protection logic to the shaft vibration transducer. This improvement increases the accuracy in the shaft vibration measurement, and the reliability in the shaft vibration protection. Furthermore, this perfection offers the experience to tackle the related issue in the domestic 600 MW direct air-cooling turbine units.
