| 摘 要： | 受到大负荷扰动后,船舶电站的参数将发生较大变化.从发电柴油机、电力负荷、发电机及励磁调节系统方面建立柴油机瞬时转速的动态模型,并从气缸做功和负载方面对瞬时转速变化方面进行分析.依据发电柴油机的不同负荷类型,分别从恒定阻抗法、电动机机电暂态过程动态特性、负荷的静态特性三方面进行归类计算,提高了负荷的动态和静态仿真性能,励磁系统则采用三阶实用模型.最后利用Matlab/SIMULINK进行了系统的静态、暂态和动态稳定性分析.

| Abstract: | The parameter of the marine diesel power station will vary largely after suffering great disturbance. This paper designs and builds the instantaneous speed model based on marine power station diesel system, load static and dynamic state calculation, the generator and excitation regulating system mathematical model. Analyze the instantaneous speed different from the cylinder work and load aspect. Building the diesel simulation real-time algorithm by volumetric method, calculating the power station load throu... |
