水轮发电机失磁动态过程仿真

Simulation of Dynamic Processes for Hydro-Generator Under Loss of Excitation

随着仿真技术在电力系统应用中的不断发展,其研究重点逐渐从系统操作、正常运行过渡到故障处理与非正常运行.结合国家电力公司实验室建设项目——大型水电站仿真培训系统研制,重点研究了大型水轮发电机失磁后的异常运行.分析了同步发电机失磁后的物理过程,建立了全系统详细的数学模型,并用Fortran语言编写了仿真程序,详细、逼真地模拟了水轮发电机在不同失磁故障下的动态过程.

With the development of simulation technique for power system, the research emphasis has changed from system operation and normal running to recovery processing and abnormal running. Based on laboratory constructing project of the State Power Corporation-the development of large scale hydropower station operation training simulator, the abnormal operation of the hydro-generator after loss of excitation has been studied. The theoretic analysis has been made for physical processes of hydro-generator after lose of excitation; accurate mathematical models of hydro-generation system have been built and their digital simulative software have been programmed; dynamic processes of hydro-generotor under different fied-loss faults have been simulated in detail and vividly.
