This paper presents the methodology and its correspondent software conceived by Daimon Engineering to propose the medium voltage distribution system work plan of CELESC. To accomplish this job, a specially designed computer program has been created to take into account several technical variables, according to the type of problem (overcapacity of conductors and voltage drops). As a result of this...
The distribution system is the final connection between the power system and consumers. If the load shedding is necessary to ensure that operating restrictions, usually this load shedding will occur in the distribution system. This paper analyzes the load shedding in medium voltage performed in the event of reduced availability of the supply system (generation and / or transmission) that may occur...
This paper aims to present and discuss the use of a power flow methodology based on Gauss Elimination Method to evaluate the performance of distribution network taking into account the neutral conductor absence at specific sections, and a development of a methodology based on genetic algorithm (GA) capable of evaluating alternative solutions in different bars of the feeder, in order to propose appropriate...
The main objective of this paper is to present the results of a new model aimed at the load forecast of a region divided by grids, using a methodology based on Gaussian filter and image dilation algorithms, which provides the load growth of each cell in the studied area, separated by their consumer classes. For that matter, the history of each grid's energy and power and the global growing rate for...
This paper aims the development of calculation models in order to make for the impact evaluation of disturbing loads. The disturbing loads considered are: induction motor, x-ray device, welding machine and electric arc furnace. On the induction motor case, it was developed an evolutionary algorithm to obtain its equivalent circuit parameters through the nameplate data.
This paper aims to present a methodology for the calculation of technical losses per segment of a power distribution system. One of the most important data is the billed energy of each customer. After this calculation, it is achieved the energy supplied by each feeder. This calculated energy is, then, compared with the measured energy. As a result of this comparison, it is possible to correct the...
The degree of complexity and the large volume of information normally associated with electrical distribution networks pose the most significant challenges for the engineers and/or operators dealing with such networks. Yet, despite the complexity of these systems, similar patterns of behavior can be identified among the same type of equipment, thus allowing a significant reduction in the number of...
In the last few years the Brazilian Electrical Energy Regulation Entity — ANEEL — has passed new resolutions regarding the quality of the electrical energy supply.
