摘要
本文采用 Riccati 多项式传递矩阵法对引进的日立公司250MW 汽轮发电机组转子轴承系统稳定性进行了计算,将得到的复特征值与用同一方法计算的国产200MW 机组的结果做了比较,分析了日立250MW 机组的稳定性优于国产200MW 机组的原因,并对国产200MW 机组的改进作了探讨。
In this paper,the stability of rotor-bearing system of HITACHI 250MW turbine generator imported from Japan is calculated using Riccati polynomial transfer matrix method.The complex characteristic values calculated are compared with the one of 200MW turbine generator made in China by use of the same calculating method.The reason why HITACHI 250MW turbine generator is better than 200MW turbine generator made in China in the vibrational stability is analyzed and some improvement for the turbine generator made in our country is discussed.
