| 摘 要： | 燃油经济性好是变速柴油发电机组的一大优势,而柴油机运行转速与燃油消耗率密切相关。以变速柴油发电机组为研究对象,建立了变速柴油发电机组的数学模型,以燃油消耗率最低为准则,用数学模型寻优和试验数据寻优两种方法开展了变速柴油发电机组的最佳运行转速研究;并进行了变速柴油发电机组油耗试验。试验结果表明:在最佳运行转速曲线上运行的变速柴油发电机组的燃油消耗率小于恒速模式下运行时的燃油消耗率;试验数据寻优得到的最佳运行转速曲线的节油性更好。

| Abstract: | Good fuel economy is a great advantage of variable-speed gensets, and the speed of diesel engine is closely related to fuel consumption. To study the variable-speed diesel gensets, mathematical model of variable-speed diesel genset was built up. With the methods of mathematical model calculation and test data optimization, the research on optimum speed of variable-speed gensets was conducted. Moreover, the fuel consumption test of variable-speed diesel gensets was carried out. The test results indicate that the fuel consumption rate of variable-speed diesel gensets running at optimum speed is lower than that of running at constant speed, and optimum speed curve got from test data optimization is more fuel-efficient. |
