| 摘 要： | 随着我国高参数和大容量机组的快速发展,特别是超临界超长机组的急剧增多,机组自身的安全性,直接影响各大电网的安全性和稳定性。超临界汽轮机转子由于转动惯量大,转子飞升时间常数小,所以对它进行超速保护尤为重要。重点分析超临界汽轮机的超速保护系统的特点。

| Abstract: | Nowadays,the number large capacity units with high parameter,especially with supercritical parameter and thin long shafts has been increased rapidly in electric networks.The safety of these units will have great impact on the safety steady of the network.As the inertia moment of supercritical steam turbine is large,and the time constant of rotor speedup is small,the overspeed protection system is very important for unit itself.The main characteristics of the overspeed protection system of supercritical steam turbines are analyzed. |
