Critical analysis of the barriers and benefits of implementing a power quality programme framework: Case study Libyan distribution networks

The purpose of this paper is to explore the obstructions faced by Libyan distribution networks in implementing a power quality programme (PQP). It is also to state the benefits, which would accrue by implementing a PQP, which would make a major impact on Libyan distribution networks (LDNs), and which could be applied and adapted internationally. In order to achieve these objectives, an extensive literature review was conducted to understand the barriers and benefits of implementing a PQP, followed by a power quality survey questionnaire and interviews. Data were collected from LDNs, both from departments and individual staff members. Both SPSS 15.1 and Nvivo 9 were used in performing the analysis. The results revealed that no PQP exists. Out of 16 barriers, 12 were statistically significant different since the P value <;0.05), which indicated that Libya distribution systems have already surmounted a few of the barriers to implementing a PQP effectively. The qualitative analysis results also showed that lack of implementing power quality programme, was due to some difficulties, which still exist and made the process of implementation very complicated and its progress very slow. The overall benefits of PQP implementation, which would have a positive impact on LDNs, are 11 benefits. The findings of this paper are applied to build a PQP framework guideline to be implemented in LDNs. The PQP framework is consisted three essential phases. Phase one designed to increase the awareness level. Phase two is involved in preparation of PQP, which contains seven crucial requirements. Phase three is designed to prevent the outstanding problems from phase 1 and 2 of not reoccurring again to determine both the weaknesses and obstacles facing the implementation. The progress of this framework and moving through from phase to other will be depended on the level of awareness, knowledge, skills gained respectively after each phase performed.
