Innovative Energy-Recovery Unit for the LED-Lighting System of Heavy-Duty Vehicles

In this work, the development of an energy recovery control unit to be incorporated in the light-emitting diodes (LEDs) lighting systems of heavy-duty vehicles is presented. This innovative industrial product adopts modern power electronics technology to improve existing trucks’ LED lighting system by eliminating the so far inevitable power consumption by the conventional central control unit of the majority of these vehicles, which is obligatory for the uninterruptable operation of their lighting system. The main idea of this innovative product is its capability to virtually increase the lighting system power consumption without actually consuming this amount of energy, thus facilitating the central control unit requirements regarding these vehicles in an energy-conscious way. Under this light, a mature power converter’s topology is employed to draw the proper amounts of power from the vehicle’s batteries supply, to the level that the central control unit recognizes, and return this energy back to the batteries. The tests results of the developed industrial product highlight the energy saving potential of the proposed energy recovery scheme, while the Life Cycle Cost Analysis (LCCA) results confirm its techno-economical and environmental profit for the truck applications under study.

Simulation of Self-Healing in Samawa City Distribution System

Self-healing is the ability of a distribution system to automatically restore power after permanent faults. This paper investigates the impact of outages in the distribution network elements following the occurrence of a fault. The work aims to restore maximum available power to consumers in the affected areas, after the isolation of faulted parts, by optimal procedure of switching operations. In this work, CYMDIST software was used for the simulation and analyses of a distribution network in Samawa City. MATLAB 2017b/Simulink was used to implement self-healing, through the simulation of smart protection system that is controlled remotely by a central control unit. The results of implementing the proposed self-healing system on Samawa a New 11 kV network show a maximum power restoration with a minimum number of switching operations that have been achieved after fault isolation without violating constraints.

Design and Simulation of Automatic Temperature Control and Alert System Based PIC16F887

In this research, the design and simulation of an automatic system for temperature control using embeddedsystem in order to automatically control of multi appliances depend on the temperature value. The appliances will becontrolled are ventilation, cooling, heating and alert. This is an order to avoid or reduce to human intervention andincrease system reliability. An important feature of this automation process is to reduce or eliminate the possibility ofrelying on the human factor operator for industries, warehouses and laboratories, and to improve working andperformance environments. The system in this paper used the microcontroller PIC16F887 as the central control unit,LM35 temperature sensor as a temperature source,16x2 liquid crystal display (LCD) as indicator to display thedifferent system working status an addition to some of drivers, relay and light emitting diodes (LED) as indicators todisplay the corresponding working appliance driver. The implementation and simulation of the system work has beenachieved by using Proteus professional software v8.0 and mikroc pro for pic v.6.6.1 software to write the equivalentprogram and generate. Hex file for system working.

Raspberry PI 3B + microcomputer as a central control unit in intelligent building automation management systems

This article aims to show the possible savings in electricity costs in smart building installations with the use of new version of Raspberry Pi 3 model B + as the control unit in intelligent building automation systems. It presents a comparison of the consumption of electricity in two units used in the central control systems, i.e. a small Windows-based computer and a Raspberry microcomputer. The power consumption of these units was measured during the rest period and during standard operations in the intelligent installation system. The conducted measurements proved that the use of the new updated version of Raspberry Pi 3 model B + as the central control unit in intelligent building management systems is more economical and energy-saving.
