If you’ve been following my blog series, you may have noticed a common thread: data drives effective decision-making. Whether you are acting on sustainability, energy efficiency, electrical resilience, safety, or any other aspect of improving operations, data is the feedstock of analytics. And the analytic tools that convert data into actionable insights are getting smarter. In a previous ...
It often involves gaining the ability “to do more with less”, and invariably means being able to deploy more powerful simulation, modelling and analysis as early in the process as possible: to focus on potential problems and key issues including durability, noise, vibration and cost right back in product planning and concept design phases. ...
Static frequency converter is changing fixed grid power through AC to DC to AC by inner electronic parts and components, the multifunctional inverter converts the mains (50 Hertz or 60 Hertz, 120V, 240V, 400V) through conversion circuit and transforms into the required voltage and frequency power source, the output power source can ...
In conventional power supplies, the mains is rectified (that means the negative parts of the main cycle are flipped over to become positive). ...
This paper deals with the analysis, design and simulation of power factor corrected (PFC), low crest factor (CF) electronic ballast for a compact fluorescent lamp (CFL). The proposed electronic ballast employs a Cuk buck-boost AC-DC converter as a power factor regulator (PFR) operating in discontinuous conduction mode (DCM). ...
This problem may be formulated using global optimisation methods in order to generate sets of design parameters to be analysed by programs that simulate the neutron interactions in the reactor core. This problem is highly multimodal, requiring techniques that overcome local optima, which can be done by promoting a greater populational diversity. ...
The switched–mode power supplies are widely used in very low voltage and high–power applications where large conversion ratios are required. ...
This paper introduces a model for simulating restoration of bulk power systems following such disruptions. The model allows analysts to simulate disruption of a bulk power system by designating system components as damaged or non–functional. ...
It optimises the inverter losses by adapting the switching sequence of electronic switches according to the power factor. Numerical simulation in Simulink was used to validate the proposed approach. The results show the effectiveness of the proposed method, which can be easily adapted to any other machine, without much complexity.Keywords: adaptive space–vector ...
In this paper, a system is proposed which includes the modification of a conventional pressure reduction station with the addition of a turbo expander and a gas turbine for power recovery and generation. The next step is investigating the effect of heat exchanger on proposed combined heat and power system. The objective of the simulation is first ...

Nuclear power plants for hydrogen production are investigated in the aspect of nuclear safety. ...
The influence of reference temperature on exergy and exergoeconomic performance parameters of a thermal plant was investigated. The plant was simulated using HYSYS (2003) process simulator software and the exergy and exergoeconomic analyses were done using Microsoft EXCEL spreadsheet. ...
The proposed power circuit that can perform multilevel inverter operation consists of three cascaded two level inverters with asymmetric DC link voltages and results in hexagonal voltage space vector structure in lower modulation region and a 12–sided polygonal space vector structure in the higher modulation region. ...
Economic load dispatch (ELD) and economic emission dispatch (EED) have been applied to obtain generation scheduling of thermal power plants at optimum fuel cost and emissions. Due to limited availability of quality coal, issue of environmental emissions and high prices of coal, installation of renewable energy systems are suggested in power grid. ...
The objective of this paper is to perform the exergy and exergo–economic analysis of Isfahan steam power plant. A simulation program is used for modelling the Isfahan steam power plant in Iran. ...
High–frequency transformer isolated DC–to–DC converters are widely used for power conversion in alternate energy and other applications. In such applications, it is important for the converter to operate with wide variations in input voltage. ...
In this present analysis, the numerical simulation methods are applied to calculate the solution for stochastic point–kinetic equations with sinusoidal reactivity in dynamical system of nuclear reactor. ...
It includes the modelling of proton electrolyte membrane fuel cell and the power conditioning unit interfacing the fuel cell to the utility grid with proper power flow control. ...
In this paper, a small wind turbine emulator (WTE) using separately excited DC motor is modelled, designed, simulated, implemented and tested. A 1 HP separately excited DC motor is used to emulate the characteristics of the rotor of small wind turbine. ...
