In many countries, non-technical losses and theft of electricity are serious problems for electricity companies. The development of cost-effective algorithms to deal with these types of non-technical losses aims to reduce trading losses. This article presents a strategy for detecting non-technical losses using an arduino UNO control board that establishes a reliable region to monitor the measured variance and a practical scheme for determining and reducing non-technical losses in the electrical network by detecting the suspicious area where incorrect meter readings and electricity thefts occur. After the detection of the non-technical losses, a path finding procedure based on different algorithms is able to locate the consumption point with the non-technical loss. In addition, an information system application displays the targeted consumption point. The numerical results demonstrate the selectivity and efficiency of the proposed methodology applied for the monitoring of a real distribution network.
DR Congo with the National Program for Space and Technological Research (PNRST), is the subject of improvement of structure of satellite own the himself.
The problem is to simulate and model the structure from the point of view viscoplasticity, vibration and cryogenic behavior at very high altitudes. Sizing will be facilitated by the following approach:
1. cracking among the modes of ruin of structures;
2. the mechanics of fracture among models dealing with the cracking of structures; 3. finite element methods among numerical methods applicable in fracture mechanics.
Global warming is making our rivers become non-navigable during the dry season, following a considerable decline; pushing the population to lock up. It seemed interesting to us to try to overcome this insufficiency by initiating the calculation of a hydroplane leading to a prototype. In this article, we will have to calculate the conditions of resistance of the structure of the hydroplane in maximum load, using the relations of the nonlinear elasticity and the plasticity in fracture mechanics, based on the finite element methods.
We designed a system consisting of two propellers. The first propeller works with the natural wind speed, the second propeller depends on the compressor compressed air that will be started when there is excessive decrease in the natural wind speed. When the wind resumes its normal speed, an optical encoder will give instructions to the microprocessor to stop the motor-compressor.
