核电百万千瓦级汽轮发电机组输出电流大，运行可靠性要求高，所用离相封闭母线均采用强迫冷却方式冷却，以增强母线散热效果，避免出现母线过热问题。因国内至今未能掌握可用于工程应用的强迫风冷离相母线热平衡计算技术，使得该设备一直长期依赖进口。该研究从工程应用角度出发，设定合理边界条件，建立数学模型，完成热平衡计算程序编制，并通过仿真及国外工程数据进行验证，证明该计算软件完全可应用于工程实际。

The rated current of the half-speed generator used in nuclear power plant is higher than that of normal plant,and higher safety requirement too. So the IPB is cooled by forced air in nuclear power plant to reinforce cooling effect and to avoid the overheated problem.But the technology of heated balance of forced air cooling IPB still not be mastered in domestic corporation to this day.In this document,the author set reasonable boundary condition,and establish the math model,and completed the research on the heated balance procedure and make the test means based on applied in the project.
