摘要
阐述了对具有低电抗与电阻(X/R)比值支路的电力系统使用补偿技术和快速分解(FDLF)②法进行潮流计算的综合研究。对串联和并联两种补偿方案都作了分析处理。方法是,通过观察和试算来确定上述二方案最理想的参数,在最佳状态下,即使一些支路的X/R比值非常低,两种方案所需要的收敛迭代次数也是相同的。使用这种补偿技术可以简便而有效地解决(潮流计算中的)许多种问题:无论是辐射支路还是环状支路,是配电支路还是三绕组变压器支路,是低压敷设电缆支路还是带串联补偿的高压架空线路支路中的问题都能解决。而且,这种补偿技术的有效性并不受病态支路的数量所限制。
This paper presents a comprehensive study of compensation techniques used with the fast decoupled load flow (FDLF) method for power systems having branches of low reactance to resistance (X/R)ratios. Both series and parallel compensation schemes have been dealt with. The approach has been to use an enlpirical investigation to determine the optimal parameters for both schemes, Under optimal conditions the two schemes need the same numbers of interations for convergence, even if the X/R ratios of some branches are exceptionally bad. The technique can be easily and efficiently used for a variety of problems;no matter whether the branches are radial or looped,distribution lines or three-winding transformers,and L. V. underground cables or H. V. overhead lines with series compensation. Moreover, thevalidity of the technique is not limited by the number of ill-conditioned branches.
