GB/T 33199.1-2016 in English

《GB/T 33199.1-2016机械振动 旋转机械扭振 第1部分：50MW以上陆地安装的透平和燃气轮机发电机组》由TC53（全国机械振动、冲击与状态监测标准化技术委员会）归口，主管部门为国家标准化管理委员会。

Scope

This part of GB/T 33199 specifies the torsional vibration criteria for the coupled shafting of the turbogenerator set with long blades installed under normal operating conditions, especially for the avoidance of the natural frequency of torsional vibration of the coupled shafting of the turbogenerator set in grid-connected operation. Open the line frequency of the grid and the range of 2 times the line frequency. It also specifies the measures that the supplier can take if the torsional vibration natural frequency does not comply with the specified frequency range. This section is applicable to power station turbine generator sets installed on land with a rated power greater than 50 MW and a rated speed of 1 500 r/min, 1 800 r/min, 3 000 r/min, 3 600 r/min and a power station with a speed of 3 000 r/min r/min, 3 600 r/min power station gas turbine generator set. This part presents the current methods for analyzing, evaluating and measuring the natural frequency of shafting torsional vibration.
