The technical code, performance features, main structure features, and features of the auxiliary systems of the THDF 108/53 turbogenerator produced by Shanghai Electric Group Company Ltd. according to the technology introduced from Siemens are recommendated. The recommendations are however also focussed upon the variable frequency start-up mode and the system structure of the F class gas turbine generator. The THDF 108/53 type generator is a turbogenerator selected to be fitted to the F class tandem compound gas turbine generating unit and distinguished for its excellent performance and its conformity with the requirements of both the international and local standards.
本论文就高海拔地区高压发电机定子端部绕组防晕问题进行了理论分析探讨及试验研究.通过采用高介电性绝缘材料对模拟定子绕组端部相间区域等进行处理,相间起晕电压提高到30kV以上,并总结出一套有效可行的端部防晕技术方案.该方案应用于修理电机和新产品电机时能使高压发电机在高海拔(200米以上)环境中运行时达到特殊的防晕要求.
The failure analysis for main leads of 300?MW water hydrogen turbine generator is presented. The testing and finite element techniques were applied into the analysis of static and dynamic responses of the main leads. Results show the cause of crack failure, which is that micro cracks, caused by vibrating deformation of hanging weight attaching to the main leads, propagates and leads to macro crack to be leaking hydrogen, due to the resonance of main leads when its working frequency tends natural one, that is 48.429?Hz~50?Hz. The improvement design was proposed finally and new design could avoid the resonance to happen.
