Electrical Distribution Architecture and Load Curves Analysis of Audiovisual System

Abstract

This paper presents an in-depth investigation of the load curve of Tunisian television as well as the power system distribution architecture. The proposed system is based on six transformers, three diesel generators and a park of batteries. The load curves analysis and the energy consumption are discussed. This is an effective tool for carrying out the studies and planning necessary to reduce the electrical energy consumption. In order to classify the loads, the electrical energy consumption is divided in two ways: 1) sensitive loads and 2) normal loads. Real-time measurements of consumption, during four seasons were carried out. As analysis results of sensitive and normal loads, it is recommended to use led lamps for lighting, to integrate a renewable energy production system and to set up an intelligent manager of loads.
