摘　　要：模拟原动系统的调速系统实现数字控制后,对原动系统的模型可以进行更精准的设置,但是模拟原动系统的仿真准确度仍没有得到定量的分析和研究。结合层次分析法和规范系数法,采用了一种定量评估模拟原动系统模型仿真准确度的方法,通过对甩负荷曲线的分时段对比分析,来得到模拟原动系统模型的仿真准确度数据。分析结果表明,该方法在评估模拟原动系统模型的仿真准确度时,能全面考虑曲线间的数值相似度和变化趋势相似度,使原动系统模型的仿真准确度评估兼具合理性和实用性。Speed regulation system of prime mover system simulator was digitally controlled.Models of prime mover system simulator could be set more precisely.But simulation accuracy of prime mover system simulator was not analyzed and researched quantitatively.By use of analytic hierarchy process（ahp） method and standard coefficient method,a method to quantitatively assess the simulation accuracy of models of prime mover system simulator was adopted.Through the compare and analysis of load rejection curves in different period,simulation accuracy data of prime mover system simulator were got.The analysis results show that when simulation accuracy of models of prime mover system simulator is assessed,the proposed method can comprehensively take the numerical similarity and trend similarity between simulation results and measured curve into account.The proposed method makes the assessment on accuracy of models of prime mover system simulator more reasonable and practical.
