Abstract

This work studies the cost benefits derivable from network reconfiguration and shunt compensation of a Nigerian 33 kV distribution network. The approach adopted requires that the base case power flow analysis of the distribution network was first carried out, after which a shunt capacitor was used for compensation. The introduction of a tie-line in the network and a combination of capacitor and tie-line on same network were also carried out. The costs analysis of compensation and reconfiguration was carried out to understand their financial worthiness. The results obtained showed that the payback period (PP) for the introduction of compensation only, reconfiguration only and combination of compensation and reconfiguration are 1286.89 hr, 328.58 hr and 1043.31 hr, respectively. Though, reconfiguration only gives the least PP, a combination of compensation and reconfiguration has a long time cost benefit. At time above 5147.57 hr, it generates more profit than others.

33kv配电网重构与并联补偿的经济性研究
本文研究了尼日利亚某33kv配电网的网络重构和分流补偿的成本效益。所采用的方法要求首先对配电网进行基本情况潮流分析,然后使用并联电容器进行补偿。在网络中引入了联络线,并在同一网络中进行了电容器与联络线的组合。对薪酬和重组进行了成本分析,以了解其财务价值。结果表明,仅引入薪酬、仅重组和薪酬与重组相结合的投资回收期分别为1286.89、328.58和1043.31小时。虽然重新配置只能获得最小的PP,但补偿和重新配置的组合具有长期的成本效益。当时间高于5147.57小时时,它比其他公司产生更多的利润。
