Solution

The correct option is D constant real and reactive power drawn from the bus
In load flow study generators are modeled as source of complex power, loads are modeled as demand of complex power and transmission lines are modeled as $π -$ model.

Q. A 10-bus power system consists of four generator buses indexed at G1, G2, G3, G4 and six load buses indexed as L1, L2, L3, L4, L5, L6. The generator-bus G1 is considered as slack bus, and the load buses L3 and L4 are voltage controlled buses. The generator at bus G2 cannot supply the required reactive power demand, and hence it is operating at its maximum reactive power limit. The number of non-linear equations required for solving the load flow problem using Newton Raphson method in polar form is

Q. A power system consists of 300 buses out of which 20 buses are generator bus, 25 buses are ones with reactive power support and 15 buses are the ones with fixed shunt capacitors. All the other buses are load buses.It is proposed to perform a load flow analysis in the system using Newton- Raphson method. The size of the Newton Raphson Jacobian matrix is

Q. Out of the following option, the most relevant information needed to specify the real power (P) at the PV buses in a load flow analysis is

Q. A lossless transmission line with 0.3 pu reactance per phase uniformly distributed along the length of line, connecting a generator bus to a load bus, is protected upto 85% of its length by a distance relay placed at the generator bus. The generator terminal voltage is 1 pu. If no generator is at the load bus, the threshold pu current for operation of distance relay for a solid three phase to ground fault on the transmission line will be________ (upto 2 decimal places)
