Power supply is one of the major problems of the banking industry of many emerging economies, such as Nigeria, particularly as the banks strive to modernize and offer quality services, such as electronic banking. This paper proposed a PV/Diesel hybrid power generation system suitable for banking. The study is based on simulation and optimization of hybrid system of a bank located in two differe...

Abstract This research focuses on the design optimization of an off‐grid hybrid energy system including photovoltaic (PV) and diesel generator considering storage (ESS). For this aim, techno‐enviro‐economic feasibility assessment PV/diesel, PV/diesel/battery, PV/diesel/pumped hydro (PHS) systems is investigated in a multi‐objective framework. Levelized cost (LCOE) total pollutant emission (TPE)...

This paper presents a standalone hybrid power generation system based on low speed wind energy conversion system (WECS) using a variable speed permanent magnet synchronous generator (PMSG) with battery storage and diesel generator (DG). Different types of power management strategies are presents for minimal use of DG. For each PMS, mathematical model is developed based on the power balance (bet...

An energy-storage flywheel consists of a large inertia wheel sharing a common shaft with a motor generator (MG) set and with magnetic bearings to support the entire rotating assembly. Flywheels mounted on a special slug car are charged from the local utility grid and from regenerative-braking events. Usage of these power sources reduces fuel consumption and the related NOx emission by the locom...

Fungsi mesin tersebut sebagai penggerak generator untuk menghasilkan listrik bagi kebutuhan di kapal. Diesel auxiliary memiliki komponen penting antara lain : pompa bahan bakar, turbocharger, air starting motor, intercooler, dan sebagainya. dari diesel a...

In recent years, need to increase the convenience of trips in railway vehicles causes that train operators and manufacturers focus on reducing the noise level which is sensed by passengers. In this paper, first the state of modeling acoustic noise in cab train is discussed and natural frequencies and acoustic mode shapes are derived and then formulation of acoustic pressure in the cab will be o...
