Optimization and improvement of ac resistance calculation method for multi-phase parallel-wiring cables
文献摘要：
Parallel-wiring cables are often used in multi-phase AC aircraft Electrical Power Systems(EPSs).However,it complicates the ac resistance estimation.To solve this issue,an analytical resis-tance calculation method for parallel-wiring cables in multi-phase EPS was proposed.Firstly,the existing calculation formula of proximity factor was optimized,and the calculation error was reduced from 16％ to 2％ when two conductors are close to each other.Afterwards,the superpo-sition effect on current density distribution between multi-conductors was considered based on orthogonal decomposition method,and the position of the equivalent charged points were easily determined.Finally,the ac resistance calculation formula was derived according to characteristics of parallel-wiring strategy,and the general ac resistance calculation methods of multi-phase parallel-wiring cables were presented.The proposed approach considerably enhances the applicabil-ity of ac resistance analytical calculation method for multi-conductor cables.Thanks to the accu-racy of the proposed method,it can be used in many cases to avoid case-by-case simulation work and facilitate efficient system design and analysis.
