【摘要】 用仿真方法分析测功法甩负荷试验已有算法误差较大的原因，提出一种改进算法，所换算的名义飞升转速在整个动态过程都有很高的精度，对漏汽情况下测功法甩负荷试验的相关问题进行讨论，并提出对试验测试方面的要求更多还原

【Abstract】 The causes for larger algorithmic error existing in load-rejection test using dynamometer are analyzed by meansof simulation. an improved algorithm is proposed. the converted nominal runaway speed in the whole dynamic processhas very high accuracy The related problems of load-rejection’test using dynamometer under steam leakage condition arediscussed and the requirements for testing and measuring are put forward as well.更多还原
