船舶电站发电机组并联的结构稳定性探讨

Research on the Structural Stability of the Parallel Diesel-generator Sets in Ship Power

根据两台柴油机交流发电机组并联运行稳定性的微分方程式 ,运用数学方法的等价定理 ,将两个微分方程组转换成一个二阶非线性微分方程 ,再通过非线性自振荡的渐近方法 ,解出二阶非线性微分方程的近似解 ,从而判定发电机组并联完全对称系统的结构稳定性。

Based on the differential equation of the stability of two diesel generator sets operating in parallel and using the equivalent theorem of mathematical methods, the paper changes the two differential equations into a second order nonlinear differential equation and then gets its approach solution by nonlinear self oscillating asymptotic method, which can be used to decide the structural stability of the diesel generator sets operating in parallel in the dead symmetry.
