power systems loss

Authored by: SALWA ALI AHMED    MOHAMMED ABD EL LATIF BADR    ABLA SOLIMAN ATIA Abstract - Reducing the losses of power distribution systems (technical and nontechnical losses) is an absolutely necessary objective in the sound management of any electrical utility and a major stake for the countries concerned and the lenders. The paper describes the context of losses in power distribution systems and deals more specifically with the corresponding diagnostics and implementation of losses reduction plan. Maneuvers include three main measures, these are: minimization of overload, voltage drop and losses, which are the main role in this paper.

The developed methodology is implemented in spread sheets format, which is simple and user friendly. It requires minimum set of input data, while giving reasonably accurate results. The approach is tested on a real TNB distribution network and the results are reasonably accurate. Additionally, the spread sheet developed based on the methodology could also be used to perform various energy auditing exercises.

Loss reduction does not only mean putting up necessary equipments or upgrading existing configurations in order to achieve such goal. Careful planning and strategic actions must always be taken into consideration in order to be more effective in doing the job. We all know that reducing losses means money savings but it also goes in hand that reducing losses will also mean spending money for capital cost in installing necessary equipments. In order to be more accurate, specific targets should be set before doing any actions. Determining the extent of losses should first be achieved before going to the next step in loss reduction. Where to focus the utility’s energy is very vital in doing this program since with this they can be efficient enough not to waste the company’s time and money. A popular Art of War principle is very applicable to this kind task and that is “To divide and conquer”. Because facing the problem head on will only bring more problems to the table, a good strategy in...
