本文主要应用Matlab/Simulink对大型发电机失磁故障的几种情况进行了仿真研究.包括在完全失磁情况下和部分失磁情况下大型发电机系统的机端定子电流,机端定子电压,励磁电流,励磁电压,输出有功功率波形的变化情况.失磁故障是一种常见的发电机故障类型,对系统有着较大危害,因此,对失磁故障的研究有着重要意义.本文首先模拟整个输电系统,应用mat lab建立一个单机无穷大模型,包括发电机、励磁系统、变压器、无功电源、线路负载、无穷大系统,输电线路等,然后在系统稳定之后,仿真出完全失磁情况和部分失磁情况,并对失磁情况进行了分析,得到了波形变化趋势的理论解释,并得到了有功功率和定子电流定子电压之间关系的简单规律.

Several kind condition of the malfunction applying Matlab/Simulink mainly losing magnetism to large-scale generator has carried out the main body of a book simulating studying.Electric current ,machine hold stater voltage ,encourage the magnetoelectricity stream ,the excitation voltage including that systematic large-scale generator machine holds a stater under preparing a part under complete loss magnetism situation losing magnetism condition,output has performed meritorious service power wave form change condition.Losing the magnetism malfunction is one kind of common generator malfunction type ,has bigger damage to system ,has importance therefore,to the go into losing the magnetism malfunction.Entire transmission system the main body of a book is simulated first,the lab applying a mat builds a single infinity model,include generator ,excitation system ,transformer ,idle work power source ,circuit loads ,infinity system ,transmission line etc.,simulate out after and then system is stable,losing magnetism condition and the part completely losing magnetism condition,condition has carried out analysis on to losing magnetism and ,the theory having got the wave form change trend has made an explanation ,has got and the simple law having performed meritorious service concerning between power and stater electric current stater voltage.
