A Novel Procedure for Quick Design of Off-Grid PV Water Pumping Systems for Irrigation
(Elektronika ir Elektrotechnika, 2021-03)
It is known that meteorological variables from meteorological online services can be used for the design of photovoltaic (PV) water pumping systems for irrigation. The software LORENTZ COMPASS in such a manner uses as ...
Voltage regulation in LV distribution networks with PV generation and battery storage
(Journal of ELECTRICAL ENGINEERING, 2021-12-22)
High penetration of photovoltaic (PV) generation in low voltage (LV) distribution networks can leads some power quality problems. One of the most important issues in this regard is the impermissible voltage deviation in ...
Experimental Investigation of Phase Equilibria in the Bi-Cu-Ge System
(Materials Research, 2021-01)
Phase diagram of the Bi-Ce-Ge ternary system has been investigated experimentally and thermodynamically extrapolated by using Pandat software. Experimental results were obtained using differential thermal analysis (DTA), ...
Thermodynamic Description of the Cu-Ge-In System: Experiment and Modeling
(Journal of Phase Equilibria and Diffusion, 2021-11)
In this work the ternary Cu-Ge-In system has been experimentally examined and analytically studied by using the CALPHAD method. The Cu-Ge-In system is interesting due to the possible application in the electro industry and ...
Influence of Temperature and Operation Time on the Fatigue Strength and Microstructure of Welded Joints of A-387Gr.B Steel
(Materials Science, 2021-11)
The main aim of our paper is to analyze the influence of temperature and service time on the fracture resistance of welded joint constituents for new and exploited low-alloyed A-387Gr.B steel (Cr–Mo type) under the action ...
Evaluation of heating efficiency and thermal comfort in special purpose vehicle cabins
(Thermal Science, 2021)
The paper presents the integrated application of two methods during testing HVAC system efficiency in the cabins of HUMMER М1151A1 and OAR 1RL-128D off-road vehicles. Spatial measurements of change in air temperature per ...
