So, the thought for the simulation design was put forward based on energy margin and temperature margin, the arithmetic of simulation design of CICC configuration was deduced, and the model of the simulation was built.
而工程上CICC导体的设计是一个多次尝试和优化的烦琐过程,为此,提出了基于稳定性裕度、温度裕度的导体设计思想,推导了关于CICC导体结构矩阵参数的算法,建立了导体数值模拟的基本设计模型,同时进行了仿真设计,并将数值模拟设计情况与工程设计值进行了比较和分析,结果证明二者吻合的较好。
In order to effectively monitor and control the turbine\'s thermal stress in the process of startup,shutdown and load changing,and for the purpose of reducing the equipment life loss,Siemens introduced the concept of the steam turbine temperature margin.
为了有效合理地监视和控制汽轮机在启动、停机以及负荷变化过程的热应力,减少设备寿命损耗,德国西门子公司生产的汽轮机引入温度裕量的概念。
Furthermore the temperature margins are introduced to confirm whether the thermal stress is overrange.
西门子1000MW超超临界汽轮机采用温度测量来确定高压主汽门、高压调门及高压外缸的部件温差,采用简化的仿真计算确定高、中压转子的部件温差,以温差表征相应部件热应力的大小,并通过温度裕量的计算确定热应力是否超限。
