Diesel engines have been a mainstay within many industries since the early 1900s. Exposure to diesel particulate matter (DPM) is a major issue in many industrial workplaces given the potential for serious health impacts to exposed workers; including the potential for lung cancer and adverse irritant and cardiovascular effects. Personal respiratory protective devices are an accepted safety measu...

A stand-alone microgrid usually contains a set of distributed generation resources, energy storage system and loads that can be used to supply electricity of remote areas. These areas are small in terms of population and industry. Connection of these areas to the national distribution network due to the high costs of constructing transmission lines is not economical. Optimal utilization and eco...

This paper presents a standalone hybrid power system using wind/PV/diesel/Battery energy system with Matlab/Simulink environment. PV & Wind are the primary power sources of the system and battery is used as a backup for long run application. Here we have also compare the performance of PV/Wind/Battery connected system with PV/Wind/Diesel connected hybrid power system. The most frequently used r...

Executive Summary When the procedure " Calculation of Railway Noise 1995 " (CRN) [Ref 1] was devised, the list of stock that was included was aimed at representing the majority of typical vehicles operating on the railway at that time. However, since 1995 the nature of the rolling stock fleet has changed considerably and there are many types of vehicle currently in operation that are not includ...

This paper examines through a thermodynamic analysis the feasibility of using waste heat from marine Diesel engines to drive an ammonia-water absorption refrigeration system. An energy balance of a diesel engine shows that sufficient waste heat is provided. The results illustrate that higher performance of the system is obtained at high generator and evaporator temperatures and also at low cond...

In this paper, a distributed generation including diesel generators, wind turbines, and microturbines are introduced, and their mathematical model is described using the Taylor expansion method. With the goal of computational complexity eliminating, the reduced order model (ROM) of microgrid components is considered. The results of the ‌‌studies indicate that the microgrid frequency is unstable...

Ideally, diesel hybrid autonomous power systems would operate with high penetration of renewable energy sources such as wind and photovoltaic to minimize fuel consumption. However, since these are inherently intermittent and fluctuating, the grid-forming diesel engine generator sets are usually required to operate with larger amounts of spinning reserve, often at low loading conditions what ten...

Off-grid settlements require efficient, reliable and cost-effective renewable energy as alternative to the power supplied by diesel generator. Techno-economic analysis is required to find the optimum renewable energy system in the long run. This paper reviews the application of genetic algorithms in optimization of hybrid system consisting of pico hydro system, solar photovoltaic modules, diese...
