摘　　要：静态励磁系统因其工作原理将引起电源波形畸变,从而影响电源下级用电设备的正常工作和励磁系统自身输出功率。介绍了6500MVA短路发电机静态励磁系统原理,在Matlab/Simulink环境下建立了静态励磁系统仿真模型,模拟了短路发电机在空载升压和短路试验时不同供电电源下静态励磁系统对电源的影响和静态励磁系统的输出特性,通过仿真分析提出满足短路发电机正常运行的电源参数。利用实验室已有条件在短路发电机空载升压时进行两种不同供电电源下静态励磁系统对电源系统影响的对比,验证了仿真计算结果。Static excitation system may distort the power supply waveform for its rectifier unit,which will affect normal operation of lower level electrical equipment and the output power of the excitation system itself.This paper briefly introduces the principle of static excitation system for 6500 MVA short-circuit generator.The simulation model of static excitation system is established in the environment of Matlab/Simulink,which is used to simulate the influence of static excitation system on power supply during the short-circuit generator’s no-load boost and short-circuit test.Output characteristic of the excitation system is also simulated.Through the simulation analysis,power supply parameters that meet the normal operation of the short-circuit generator are proposed.Using the existing conditions in the laboratory to compare the impact of the static excitation system on the power supply system under two different power supplies when the short-circuit generator is no-load boosting,the simulation calculation results are verified.
