Due to unreliability of power supply from national grid, high cost diesel and maintenance generators being an alternate for there is need adopt a renewable energy source efficient reliable supply. Savings associated with conversion stand-alone generator powered system PV/Diesel hybrid storage in batteries Bayero University Kano Library using HOMER software was presented this study. The economic...

The production of fatty acid methyl esters (FAMEs) from waste activated bleaching earth (ABE) discarded by the crude oil refining industry using lipase from Candida cylindracea was investigated in a 50-L pilot plant. Diesel oil or kerosene was used as an organic solvent for the transesterification of triglycerides embedded in the waste ABE. When 1% (w/w) lipase was added to waste ABE, the FAME ...

The demand in the technology requirements for diesel engines is growing keeping hybrid vehicles in mind. In future the diesel engine no longer drives the wheels directly; as a result the engine can be engaged at a limited number of operating points, thus, offering an opportunity to optimise the fuel efficiency and performance at those operating points. The extent to which this optimisation is p...

Diesel engine has been used as the primary mover in vehicles for a long time. It is known that around 25%–30% of fuel energy wasted exhaust gas from diesel engines. In this study, turbine power generation system including 1.8 kW 60,000 r/min high-speed permanent magnet generator and micro turbine, which coupled to designed modeled investigate its potential recovering engine. Computational model...

This paper presents the design and performance of a compact dilution sampler (CDS) for characterizing fine particle emissions from stationary sources. The sampler is described, along with the methodology adopted for its use. Dilution sampling has a number of advantages, including source emissions that are measured under conditions simulating stack gas entry and mixing in the ambient atmosphere....

Modeling of a wind diesel integrated system (WDIS) is done to perform under varied wind and load conditions on MATLAB Simulink platform. This hybrid system is design in such a way that uunder low wind conditions, a diesel generator feeds the required power to the load. A load flow controller is designed for WDIS to control the load flow depending on the load condition. The power controller redu...

The photovoltaic-diesel-battery (PDB) hybrid system is proposed previously to satisfy power requirements in some remote areas locating out of national power grid. However, to dispatch the uses of different components in PDB hybrid system remains a problem. In this paper, mathematical model of the PDB hybrid system is transformed into an MIMO linear statespace form, and model predictive control ...

Hybrid energy systems such solar and wind energy in combination with diesel generator can be applied successfully in areas where grid connection is not available or considered uneconomical. Their costs can be minimized through proper equipment sizing and load matching. This study represents the cost analysis of various models of hybrid systems for powering a remote area telecom tower located at...
