【摘要】：构建了永磁偏置型故障限流器PMFCL的经济性分析模型,包括材料成本和运行成本两部分。材料成本取决于PMFCL的关键结构参数,基于等效磁路法导出了PMFCL 4个关键结构参数与电感和、电感比以及饱和深度比这3个独立电磁变量间的函数关系;运行成本由铁芯损耗和绕组铜耗组成,并给出了各自的计算方法。针对500 k V PMFCL经济性分析实例,分析了电磁变量对PMFCL经济性的影响,并建立其经济性优化模型,求得了PMFCL的最优成本和对应的结构参数。结果表明,在高压大容量应用场合,PMFCL具有较好的经济性优势。Ansoft Maxwell二维有限元仿真验证了经济性优化模型的合理性。
[Abstract]:The economic analysis model of permanent magnet bias fault current limiter (PMFCL) is constructed, which includes material cost and operation cost.The material cost depends on the key structural parameters of PMFCL. Based on the equivalent magnetic circuit method, the functional relationships between the four key structural parameters of PMFCL and the inductance sum, the inductance ratio and the saturation depth ratio are derived.The operation cost is composed of core loss and winding copper loss, and their calculation methods are given.Based on the example of 500kV PMFCL economic analysis, the influence of electromagnetic variables on PMFCL economy is analyzed, and its economic optimization model is established. The optimal cost and corresponding structural parameters of PMFCL are obtained.The results show that PMFCL has a good economic advantage in high voltage and large capacity applications. Ansoft Maxwell two-dimensional finite element simulation verifies the rationality of the economic optimization model.
