摘要:
 为更完善、更准确地研究发电机并网运行下,发电机非正常运行时的机网动态问题,建立了控-场-路-网耦合的单机-双回线-无穷大系统联合仿真模型,实现了励磁控制系统—发电机二维瞬态电磁场—外电路—电网的全面耦合。并以某动模实验电机为基础,通过对发电机定子绕组匝间短路故障的仿真与实验结果对比,验证了仿真模型的正确性。与此同时,为验证该模型在大型发电机组中的应用效果,另以一台核电半速汽轮发电机为例进行了定子绕组匝间短路故障仿真,并将仿真结果与传统的恒定励磁电压法建模的仿真结果比较,分析结果表明所建的控-场-路-网联合仿真模型能更准确、更真实有效地反映发电机非正常运行时机网协调运行的动态过渡过程。
Abstract:
 To investigate the non-normal operation state of synchronous generator in detail,connectingwith the power grid,a co-simulation model of one generator-double circuit transmission lines-infinite bussystem is established based on control-field-circuit-network coupling. It implemented the couplings of ex-citation control system,
wo-dimension transient electromagnetic field,external circuit and power grid inthe model. Taking a laboratory's generator as an example,and comparing the simulation results of the in-ter-turn short circuit of the armature winding with experimental data,the correctness of the model wasvalidated. Meanwhile,in order to test the application effect of the model in large generator,taking a nu-clear power half speed turbine generator as an example,the simulation of inter-turn short circuit of the ar-mature winding was presented. Through comparing the simulation results of the method proposed in thepaper with those of the traditional constant excitation voltage method,it shows that the control-field-cir-cuit-network co-simulation model proposed in this paper is more accurate,realistic and effective in reflec-ting the generator-network dynamic transition process of the generator in non normal operation than tradi-tional methods.
