Software Development for Comprehensive Analysis of Losses in Electric Power Distribution Networks

Abstract

Losses in electric power distribution lines pose a significant challenge for energy distributors. These losses not only affect the network’s efficiency but also have economic and environmental impacts. There are two main types of losses: technical and non-technical. Technical losses occur due to the resistance of cables and transformers, while non-technical losses are related to factors such as fraud, measurement errors, and improper connections. To mitigate these losses, adopting effective strategies is essential. One approach is to invest in advanced technologies, such as real-time monitoring systems and automation. Additionally, preventive maintenance and the replacement of worn equipment are crucial for reducing technical losses. Recently, the electricity distributor Cooperativa de Eletrificação Centro Jacuí LTDA, from the state of Rio Grande do Sul, developed proprietary software specifically designed to analyze the behavior of low-voltage (LV) networks. This software allows for the assessment of transformer loads, monitoring voltage levels, and simulating the integration of distributed generation (DG). It also considers network behavior throughout the day, accounting for various load levels. Furthermore, the software assists in evaluating the impact of transformer and cable replacements, as well as determining the distance of consumer units from the transformer.
