The irradiation values measured on location yields an average solar irradiation for the entire analysis period of 120 kWh/m².
This irradiation value is extrapolated to the modular area of the PV plant as follows:
Irradiation value in kWh/m² x plant area in m² = 120 kWh/m² x 10 m² = 1,200 kWh
In order to subsequently calculate the nominal plant output, the irradiation value for the PV plant is multiplied by the modular efficiency:
1,200 kWh x 15 % = 1,200 kWh x 0.15 = 180 kWh
PR = 110 kWh/180 kWh = 0.61112 = 61.11 %
Slip, s = (Ns - Nr)/Ns
Ns = 120f/P
Ns = 1500 rpm
s = (1500 - 1425)/1500
s = 0.05
%s = 5%
In single phase energy meter,
Current coil is made up from thick wire having few no. of turns.
Pressure coil is made up from thin wire having more no. of turns.
Standard eqution of current for this condition,
i(t) = i(0+)*cos(wt)
i(0+) = E/R
For LC circuit,
w = 1/√(LC)
i(t) = (E/R)*cos((1/√(LC))*t) A
