Load flow analysis
Load flow analysis is a study or numerical calculation of the power flow of power in steady-state conditions in any electrical system. It is used to determine the flow of power (real and reactive), voltage, or current in a system under any load condition…
Nodal Matrix
The nodal matrix or simply known as admittance matrix, generally in engineering term it is called Y Matrix or Y bus, since it involve matrices so it is also referred as a n into n order matrix that represents a power system with n number of buses. It sho…
Types of Buses
A bus is a type of system of communication that transfers data between the components inside a computer or between two or more computers. With multiple hardware connections, the earlier buses were parallel electrical wires but the term "bus" is now used …
Question

A synchronous generator has 4 poles and a synchronous reactance of 5 ohms. The operating frequency is 60 Hz. The stator windings are connected in Y and the voltage between the lines is Vl= 15 kV. The generator line current is 1 kA with a power factor of 0.9 (lagging). Find:
a) The amplitude of the excitation voltage (induced voltage Eaf. ).
b) The actual power delivered by the generator.
c) The reactive power supplied by the generator.
