At no load the solar cell will be operating in open circuit condition.
If there is internal shunting resistance it will slightly load the solar cell.
This shunt resistance must be high enough such that it will not cause an appreciable loss of the photo voltaic power.
In Fast-decoupled method,
Order of B' = No. of PV buses = 5
Order of B'' = No. of PQ buses = 3
1. e = 4.44fφ*Turns
2. V/f ≈ e/f ∝ φ ∝ B
3. Eddy Current loss, Pe ∝ B²f² ∝ f² (as B is constant if V/f is constant)
4. Hysteresis loss, Ph ∝ B^1.6*f ∝ f
If V/f is constant, B is constant, mmf required to create B is constant, Im is constant.
When neutral disconnected, lamps are in series connection,
So, for series connection current is same for both Lamp,
So, Resistance of 100 W Lamp is more compared to 150 W Lamp.
Hence after neutral connection disconnect 100 W Lamp is more brighter than the 150 W Lamp.
M = k√(L₁L₂)
M = 135 mH
L_eq for opposite connection of coils = L₁ + L₂ - 2M
L_eq = 900 + 100 - 2*135
L_eq = 730 mH
