Here, Y phase is shorted,
Equation of 3-phase power = √3*VL*IL*cosφ
IL = P/(√3*VL*cosφ)
= 12.55 A
Phase impedance = Vp/Ip
= 21.16 ohm
cosφ = 0.8, So φ = 37 degree.
Here Impedance of Y phase is shorted,
So, Neutral point and Y phase at same potential,
Three line voltages are given by,
Vry = 460∟0°
Vyb = 460∟120°
Vbr = 460∟-120°
Here N and Y phase at same potential,
Ir = (460∟-120°)/(21.16∟37°)
= -21.7∟83° A
Ib = (-460∟120°)/(21.16∟37°)
= 21.7∟-157° A
Ib = -(Ir + Iy)
= -21.7∟83° + 21.7∟-157°
= 37.6∟53° A
As per the key statistics data of IEA With electricity consumption reached to 1,164 TWh in the country till November 2019, India ranked third among the top ten electricity consuming countries across the globe.
In DC microgrid system,
Efficiency α 1/Pin
For 1 kW loss injecting power is 20 kW
For 1.5 kW loss injecting power will be proportional to 30 kW
Efficiency will be reduced 0.025
For small turbine starts generating power 12.6 kph (3.5 m/s) is the typical cut-in speed.
At 36–54 kph (10–15 m/s) produces maximum generation power.
At 90 kph (25 m/s) maximum, the turbine is stopped or braked.
