中文摘要: |
光控励磁系统是一种新型同步发电机无刷励磁控制系统,它是在普通无刷励磁控制系统中用可控器件(SCR或IGBT)取代不可控的二极管整流,并通过光电耦合形式实现对励磁电流的直接控制。在MATLAB/Simulink环境下,对光控励磁系统进行了建模、分析和仿真.结果表明:光控励磁系统对于提高同步发电机的响应速度,改善电力系统的暂态和稳态性能有明显效果。 |
英文摘要: |
The paper presents a novel bmshless excitation control system of the synchronization generator-optical control excitation system. It substitutes controllable devices( SCR or IGBT) for uncontrollable diode on brusliless excitation control system, and directly controls excitation current by photoelectric coupler. Mathematical model, analysis and simulation are given on the software MATLAB/Simulink. The results prove that the optical control excitation system can pnjmote the response ratio and improve the steady - state and transient state characteristic of the power system. |
