What is Power plant: Definition and 119 Discussions

A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid.
Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current.
The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Clean energy sources include nuclear power, and an increasing use of renewables such as solar, wind, wave, geothermal, and hydroelectric.

    Risk of operation in power plant

    Recently the commissioning part of our company started a new project in a gas turbine power plant with six individual power generation units, each 160 MW. Each power unit includes one auxiliary medium voltage switchgear to supply internal consumptions. Also common switchgear is considered for...

    Power Plant Efficiency & Heat Dissipation Calculations

    [SOLVED] Power plant Hi! Here i have a problem : A power plant generates 400 MW of electric power.It has an effieciency of 40%. a) At what rate does it dissipate heat? b)If the waste heat is carried away by a river, and the temperature rise of the river must not exceed 3°C, what flow rate is...

    Steam Power Plant: Solve Home Work Task

    Hi guys been given the following as some home work, haven't got a clue really its a bit confusing! Steam ar 40 bar and 400C enters the high pressure turbine of a steam power plant at a rate of 20kg/s and explands to a pressure of 3 bar at which point it is just dry saturated. at this point...

    Efficiency Analysis of a Steam Power Plant with Reheat and Feed Heater

    Hi guys, very similar to my other thread apart from this is work from Thermofluids 2! Steam ar 40 bar and 400C enters the high pressure turbine of a steam power plant at a rate of 20kg/s and explands to a pressure of 3 bar at which point it is just dry saturated. at this point part of the...

    Solar Power Plant Idea for Review

    Hi to everyone, For a while (which is only a few weeks) I have been thinking about a solar power plant with additional features. Here is a brief outline. Take an arid area close to the sea (Sahara, Saudia Arabia, parts of Australia etc.) Focus sunlight via computer controlled mirrors to a...

    Working in a nuclear power plant

    Australia is going to move to nuclear power over the next decade. I would like to work in this area but don't have a degree. I have a particular interest in physics and have done a year of university maths/physics befor giving up. At the time I was getting average scores and had no prospect of...

    Nuclear power plant at 34% efficiency - rising temperature of water

    A nuclear power plant generates 500MW at 34 percent efficiency. The waste heat goes into the connecticut river with an average flow of 3x10 to the 4th kg/s. How much does the water temperature rise? (it requires 4.8x10 to the 3 to raise the temperature of 1kg of water 1K

    Can a nuke power plant just blow up?

    Ok, I was watching the movie "Resident Evil: The Apocalypse" the other day. The big evil "Umbrella Corporation" nukes a city to kill the T virus (which is what makes the people turn into zombies ) The cover up for the city getting vaporized is too just say that the local nuclear power plant...

    Practical size limit to nuclear power plant?

    Assuming the current anti-nuclear public/political climate remains in place and no new nuclear plant sites would be allowed (nor within a reasonable timeframe) why not just simply increase the existing capacity? For a hydro plant it makes sense there is only so much water that can be...

    Calculating Coal Usage for a 1000 MW Steam Power Plant

    At a steam power plant, steam engines work in pairs; the rejected heat from the first is the heat input to the second. The operating temperatures of the first are 670 C and 440 C. The operating temperatures of the second are 440 C and 290 C. Assume both engines work at 60% of their Carnot...

    Creating a nuclear power plant

    How long does it take for a nuclear power plant to be built and to have its first reactor come on line? Let's start the time line at basically when the permit is requested and end it when the first reactor goes fully online. What kind of time period are we looking at there in the best case...

    What is the significance of pursuing reversibility in power plant processes?

    Carnot Cycle is the ideal heat engine cycle with maximum efficiency. We use Rankine Cycle as the working cycle for steam power plant which has significantly lower efficiency that Carnot Cycle. My question is why we don't adopt Carnot Cycle as ideal Steam Power Plant cycle? Thanks in advance!

    How long is nuclear power plant waste really dangerous?

    I know that some of the isotopes have extremely long half-lifes. However, isn't it true that generally speaking, a longer half life correlates to a lower rate of radioactivity? So wouldn't the most dangerous elements be those with short half-lifes? Isn't most of the danger from waste therefore...

    Government has decided to build a power plant nextdoor

    Here's an interresting poll for you all. The government has decided to build a power plant nextdoor. You have no way to convince them to put it elsewhere (just assume you drew the short straw). You also don't have the means to move away for at least 10 years. They do give you the choice...
