Abstract This research reports on the application of transfer function in performance assessment of power distribution facilities of utility companies: Shell and PHCN. It involves taking input-output data from transformers over a 1-year period and developing transfer functions of the bimonthly transformation processes for the period. The results indicate that the distribution facility of Shell had higher coefficients of performance (COP) than PHCN facilities. The average efficiencies of Shell's distribution facility were well within 90–98 percent recommended by the IEC while that of PHCN's facility were below. Generally, there were correlation between coefficient of performance and efficiency, but in some cases a high efficiency corresponded to low COP, a paradox confirming the superiority of COP as a metric for performance assessment.

基于传递函数的配电设施性能评估：配电变压器案例研究

摘要 本研究报告了传递函数在公用事业公司：壳牌和 PHCN 配电设施绩效评估中的应用。它涉及从变压器获取 1 年期间的输入-输出数据，并开发该期间双月转换过程的传递函数。结果表明，壳牌的配送设施比 PHCN 设施具有更高的性能系数 (COP)。壳牌配送设施的平均效率完全在 IEC 推荐的 90-98% 之内，而 PHCN 设施的平均效率则低于此水平。一般来说，性能系数和效率之间存在相关性，但在某些情况下，高效率对应于低 COP，这一悖论证实了 COP 作为绩效评估指标的优越性。
