KWh calculation

Question

If I like to obtain the energy consumed (KWh) in three phase circuit with load under a particular time period. Then how would i will be able to that.

Answer 1

The energy consumed in a three-phase circuit can be determined from the active power values over time. If the active power is constant during the observation period, the energy is simply the product of power and time. However, if the active power varies, the energy is obtained by summing the contributions of power at each time step multiplied by the sampling interval. This method ensures accurate estimation of energy consumption for both steady and time-varying load conditions.

Answer 2

I propose using a three-phase meter component and then an integrator at its output. The output of the integrator would be the total energy in Ws, so then you can just scale it to kWh.

Comments

So it will start as soon as the simulation will start. But i want it to start at specific time, with a switching pulse.

can you upload the screenshot if possible of circuit diagram of possible.

I don't have a circuit built, but you can use a resetting input of the integrator component to reset the value to zero at any specific time. See more details about integrator resetting here: https://www.typhoon-hil.com/documentation/typhoon-hil-software-manual/References/accumulator_integrator.html

Thanks for support. I done that.
