摘　　要：本文介绍了发电机空载阶跃试验的基本原理、试验方法以及合格标准,对试验及仿真涉及的参数,如发电机组惯性时间常数Tj、直轴瞬态开路时间常数Td'o、电压调节器放大器增益KA及调节器PID增益K进行分析论述,提出了参数获取和处理应注意的问题.利用PSD-BPA暂态程序,结合工程实例对发电机空载阶跃试验仿真参数进行不同取值下的仿真试验,对仿真结果波形进行对比分析,得出各参数对仿真结果的上升时间、振荡次数、调节时间以及超调量的影响.This thesis introduces the basic principles, experimental methods and eligibility criteria of generators no load step experiment, analyses and demonstrates the parameters involved in experiment and simulation, such as generator unit inertia time constant Tj, direct-axis transient open circuit time constant Td′o , voltage regulator amplifier gain KA and regulator (PID) gain K, and puts forward problems to be considered in parameter acquisition and processing. By utilizing the PSD-BPA transient process and combining engineering projects, the thesis conducts simulation experiments of no load step experiment simulation parameters of generators under the different values, and makes a comparable analysis of waveform of simulation results, thus concludes the influence of each parameter on rise time, number of oscillations, accommodation time and overshot of simulation results.
