Design and Application of a Control System For DC Motors Over Power Line
(IEEE, 2014) Çolak, Alperen Mustafa; Garip, İlhan; Demirbaş, Şevki
Communicating high frequency control signals over a power lines is well known and getting popular day by day. This technique is known as power line communication ( PLC) and mostly used to control the loads in short distance. In this study, authors present to control a DC motor over a power line. For this purpose, a transmitter and receiver have been used on the power line. High frequency control signals are sent by the transmitter and received by the receiver at other side of the line. In this way, DC motors is run and stop. This whole system is controlled by a microprocessor PIC16F877A at 33 kHz. Experimental results show that the proposed system is successful and can be applicable for controlling of other loads.
Modeling of Photovoltaic Solar Array Under Different Levels of Partial Shadow Conditions
(IEEE, 2014) Humada, Ali Mahmood; Samsuri, Fahmi B.; Hojabri, Mojgan; Mohamed, Mortaza B.; Bin Sulaiman, Mohd Herwan; Dakheel, Taha Hamad
Different methods of configuration have been formulated regarding photovoltaic solar power by employing several techniques. This has been done because of the varying conditions so that the loss of power can be minimized. The main factor which decreases energy output of the photovoltaic PV solar systems is partial shadowing. The way the energy output of partially shadowed arrays varies with the system configuration used, has been studied extensively. A huge degree of disorder still exists, particularly with respect to the best modularity grade for these systems. There are two distinct sub-divisions in the systems implemented in the reconfiguration mechanism: reconfigurable solar arrays, and a switching matrix to do a reconfiguration. Using different methods, the proportions of shadowing obstructions were noted to allow for calculation of the likely shadowing losses. The outcomes of this paper on modeling and monitoring are used to evaluate the photovoltaic system with respect to shadowing losses with different levels and their reliance on the system configuration are selected. It has been found that power loss because of varying conditions is majorly due to the decrease in radiance occurring on the photovoltaic array and can be avoided through selecting the suitable configuration and connection. The simulation results show that the output characteristics of the simulator presented better results with that proposed model.
