摘　　要：依据某型燃气轮机动态试车性能数据,应用VBA平台编制稳态性能处理程序,提出数据特征点的提取方法、参数速率计算方法和升降状态判断方法,在提取出特征点的基础上,通过分析动态过程得到某次燃气轮机试车性能参数变化率的变化最大值,并对单次试车性能参数阶跃段和平稳段进行了比较。The steady performance calculation program of a gas turbine was built based on VBA platform according to its dynamic performance test data.The picked up method of data characteristic point,parameter change rate calculation method and up-down state detect method were proposed.The rule and maximum value of performance parameter change rate were obtained using dynamic analysis.The parameter steady phase and dump phase was contracted for a test.
