To investigate the subsynchronous oscillation (SSO) problem of the steam turbine generators near the rectifier station of Guizhou-Guangdong Ⅱ±500 kV DC transmission link, the unit interaction factor (UIF) analysis and the time domain simulation methods are adopted.
针对贵广二回直流输电系统可能引起整流站附近汽轮发电机组次同步振荡的问题,采用机组作用系数法和时域仿真方法进行了分析。
Based on a finite element analysis,we discuss the composite effect and the connection breaking mode,focusing on the performance change of the composite effect in adopting high strength steel.
随着高层钢框架结构梁柱构件逐渐向高强材料、组合受力方向发展,在梁柱组合节点中,钢材强度对节点性能和混凝土楼板组合作用的发挥有显著影响。
In the design of the steel frame connection,when the concrete strength is increased,the composite effect of the concrete slab on the mechanical performance of the connection becomes more and more significant.
在多高层钢框架梁柱节点中,随着混凝土强度的提高,混凝土楼板的组合作用对节点力学性能的影响变得更加突出。
