[Problem of calculating the electricity production of a hydroelectric power station]

Active power production this month = difference in meter active power reading x (PT transformation ratio) x (CT transformation ratio)

= (2834-1317) x 380 /100 x 1000/5

Reactive energy production this month = difference in meter reactive power reading x (transformation ratio PT) x (transformation ratio CT)

Real Cosφ = active power/apparent power

=(2834-1317) / Sqrt [(2834- 1317)x(2834-1317)+ (434-103)x(434 - 103)]

[Active energy/reactive energy = active power/reactive power time shift]

Since the output active power and reactive power are both positive, the power plant generates not only There is merit and there is no merit.

[Hydroelectric power station door tables all have directions. We assume above that the electrical energy sent by the power plant is positive, that is, the electrical energy of the power generation state of the plant is positive. ]
