摘要
提出了一种新型的整流发电机供电系统区域间限流保护方案及限流器电路。给出了适用于限流器分析的整流发电机的简化模型。建立了该型限流器的数学模型,得到了整流发电机电源参数对FCL承受的最大电压和最大电流的影响关系,通过MATLAB仿真验证了简化模型和所推导结论的正确性。研制出小功率实验样机,完成了三相整流同步发电机直流侧突然短路故障时限流的动态模拟实验。实验结果表明该限流器设计合理,限流效果明显。
A new FCL（Fault Current Limiter） protection scheme is proposed, which is between two commutation generator power supply system regions and a simplified model of commutation generator that is applied in analysis of FCL. A mathematical model is established for this kind of FCL. At the same time, this work has obtained the maximal voltage and maximal current stood by FCL. The simplified model and the results derived from it has been proved to be correct by simulation tool（matlab）. A low power prototype has been worked out, and current limitation dynamic simulation experiment is finished for three-phase synchronous sudden short machine at DC side, and the experimental results testify the rationality of FCL design. The current limitation effect is clear.
