摘要
针对目前船舶柴油发电机组普遍采用低阶数学模型,在大扰动下分析计算时会造成误差偏大的缺陷。在分析船舶柴油发电机组系统构成的基础上,建立同步发电机、柴油机及调速系统和励磁系统的七阶非线性数学模型,采用隐式梯形积分法并用C#编程求解发电机组的非线性数学模型。在求解模型的基础上,画出船舶柴油发电机组在大扰动下的转速和电压变化仿真曲线,分析比较该曲线的各项指标,结果表明各项性能指标均在规范要求范围内,进一步验证了该数学模型的有效性。
In view of the low order mathematical model of the marine diesel generator, it will cause big error in the analysis under large disturbance. Based on the analysis of the marine diesel generator. The seven order nonlinear mathematical model of synchronous generator, diesel engine, speed regulation system and excitation system is established and solved. At the same time, simulation curve of speed and voltage are drawn. Then, we analysis and comparison of the indicators of the curve, the results show that the nonlinear mathematical model fulfills specification requirements.
