This discussion aims to show how the world's investment in power generation is. In Brazil, the current investment is made more in photovoltaic and wind power.
Hi everyone,
I am working on a project on digsilent, and i would like to know how i can run this optimal power flow analysis.
Resistances in transmission system are negligible, so 1.0pu voltage assumption holds. However, in distribution system, resistances are not negligible. Please provide information about some simple ACOPF relaxation method. Thanks.
Could you please send examples along with the frequency , size of the inductor and charge and type of charge
because I want to compare my derived formulas for the Q factor .
A constant AC voltage is desired from a variable supply voltage. The constant output gives known benefits such as energy savings and prolonged lifespan of equipment.
How to calculate the cost of a solar power plant? what are the components used in calculation?Please also comment on the losses which are considered in solar power generation?
Thank You.
We know that ground vibration resulting from blasting operation can be measured using Geophone. But how about measuring vibration of an electric pole?
data or orientation are welcome
I can use both of these electric generators because of importance of efficiency in power generating i don't know which type is better. the dimensions and working conditions are similar.
I want to make a simulation model for the three phase voltage source inverter using PWAM Scheme. The magnitude of the input DC source varies according to requirement with the inverter switching. I have to understand the switching pattern for it. I have gone through the literature available for it, but bit confusion about it. If some one has done some work on it, can just provide me the model? I need 230 V output with 50 Hz Frequency.
I am currently doing a literature review on this topic.
How to calculate reactive power consumption by star connected capacitor bank at the output of three phase inverter? Is it 3*V^2/Xc ? what should I take V as line voltage or phase voltage?
Can i design grid synchronizing inverter without PLL..can you suggest me any other or alternative methods of designing grid synchronizing inverter. The main area of focus is in Renewable energy grid integration.
Hello, Can anyone tell me why we have a greater electric consumption in a reciprocating Freon compressor when we increase the evaporation temperature?
Both the tests let us know about the core losses and copper losses in single phase transformer, then why is sumpner's test preferred over "open circuit and short circuit test" ?
Currently, thin films from nanoparticles are widely used in solar cells. What are the other properties that can be improved to improve solar cell efficiency?
I am not talking only about air pollution. I am asking any type of pollution from hydro power plant.
Is it possible, considering fluid mechanical problems and temperatures in the selection of materials? Do you know of any cases? Is it feasible economically?
I am currently working on the development of a control module, using the PSpice tool, in which we developed a driver circuit - the problem I face is that I am not able to simulate the relay part in the simulation.
Could anyone please lend their expertise in this field?
Are there any devices designed for this purpose?
Is there any possibility to covert an anergic form of heat energy into useful work?
Does anybody know of an authoritative source for ‘parasitic electricity consumption’ in buildings?
