The agriculture sector nowadays relies mostly on conventional energy sources and traditional irrigation ways. Considering some factors such as high costs of fossil fuels and providing new power lines, especially to remote locations and where grid electricity is either inaccessible or expensive, a solar PV powered irrigation system can be a practical choice for irrigating crop fields. In this paper, a PV-powered dc water pump system design for irrigation is presented. A comprehensive comparison between Direct Current (DC) and an Alternative Current (AC) motors powered by PV is carried out in terms of power, current, water discharge and cost. Dominant factors of the system such as the effect of solar radiation on motor power, current, and water discharge are considered in this study. The optimum tilt angle for Duhok city is considered to perform this study. The specifications of PV, DC and AC motors are tested in Matlab Simulink to show the performance of the system components. The results show that DC motor is preferred over AC in term of system complexity, cost and power consumption. In contrast, water discharge of AC pump is slightly higher than the DC pump for the same time. However, overall results demonstrate the superiority of DC motor over AC.

Operating Modes

As the largest unit capacity of nuclear power plant at present, the flow conduit of circulating water pump in EPR1750 nuclear power plant is a volute conduit, which is a cast-in-situ conceret structure with complexly gradual change cavity. Therefore, the hydraulic efficiency of circulating water pump is not only related with the design of pump leaves, but also closely related to the design of volute and the complicated spatial type of intake and outtake conduits. With the pump leaves and the intake and outtake conduits of conceret volute as the research model, based on computational fluid dynamics (CFD)and the three dimensional Reynolds averaged Navier-Stokes equations, an analytic model suitable for computation is established to simulate the three-dimensional steady flow in the whole pumping system under different operating modes. By use of the commercial fluid-computation softer ANSYS, the distribution of basic physic quantities in the fluid field inside the pump and the conduits is obtained. The analysis and prediction of the performance of pump system are made, and the spatial type design of intake and outtake conduits is evaluated. The calculation results can be referenced to improve the design of pump systems in the similar projects.

Commutation Torque Ripple

Brushless dc motor still suffers from commutation torque ripple, which primarily depends on transient line current in the commutation interval. In order to control the incoming and outgoing phase currents to change at the same rate during commutation, this paper presents a novel high boost ratio DC-DC circuit topology in the front end of the inverter. With a suitable closed loop control scheme, the proposed high boost ratio DC-DC converter is operated with two different duty ratios one during commutation period and the other during non commutation period. The cause of commutation ripple is analyzed, and the way to adjust the duty ratio for obtaining the desired dc link voltage is introduced in detail. Finally, simulation and experimental results show that, compared with the existing dc–dc converter topologies, the proposed method can obtain the desired voltage much faster and minimize commutation torque ripple more efficiently

Exchange Membrane

Direct Current (DC) motors can be directly powered by Proton Exchange Membrane Fuel Cell (PEMFC) Stacks, to obtain plants with little maintenance and good reliability. To obtain a suitable efficiency working plant, it’s necessary to correctly match the load in order to operate in proximity to the best power line of the FC stacks generator. Otherwise by a proper field current regulation of a separately excited DC motor directly powered by a FC stacks generator, it is possible to extract from the generator itself the correct power for every temperature level. The present interest for this problem has advised the Authors to perform an experimental investigation, whose results are reported in this paper, about a centrifugal water pump powered as above c/o the machines laboratory of the Mechanical Department of the University of Palermo.

Make an analysis and points out that the engineering conditions of variable speed working condition of water pump in line with the proportionality law are as follows: non-back-pressure system, all parallel pumps changing speed synchronously (including a single variable speed pump system) and fixed pipeline characteristic curve. Energy saving effect analysis of variable speed pumps should be based on the energy consumption comparison of the pump variable speed control to other flow control methods in conditions of achieving the same flow, but not to the design working condition.
