Discussion Overview

The discussion revolves around the concept of power generation, specifically focusing on the time it takes for a generator with a capacity of 100MW to produce energy. Participants explore the distinction between power (MW) and energy (MWh), as well as operational aspects of generators.

Discussion Character

  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Some participants express confusion about the meaning of a generator's capacity of 100MW, questioning how long it takes to generate that amount of power.
  • One participant clarifies that MW is a rate of energy generation, indicating that a generator producing 100MW will generate 100MWh of energy in one hour if fully loaded.
  • Another participant inquires about the time it typically takes for a generator of that size to reach full power after being activated.
  • A participant provides a conversion of 100MW to joules, emphasizing the energy output in terms of joules per second and per year.

Areas of Agreement / Disagreement

There is no consensus on the specific time it takes for a generator to reach full power, and multiple viewpoints regarding the understanding of power versus energy remain present.

Contextual Notes

Participants have not fully addressed assumptions regarding generator startup times or operational conditions that may affect power generation.

Hi all...people always tell that the machine has a generating capacity of say 100MW..now... my doubt is..in how much time it generates those 100MW..that is in a day or in an hour something like that?

This may be a basic doubt...i don't know..but i can't help it...


Thanx

Assuming it is loaded with a 100MW consumer, the generator will produce 100MW at any given time. In one hour, it will have generated 100MWh or megawatthours of energy..for which the user will be charged...if it is a commercial generator.
 
To put it another way, MW is a rate of energy generation, not a quantity of energy generated.

How much time does it usually take for a generator that size to turn on to full power when activated?

Thanx

100MW = 100,000,000 Million Joules per SECOND

Equivalent to 3.1556926 * 10^15 joules per YEAR
 
thanx for the info guys
