Abstract
This main objective of the project is to identify the fault occurring in the grid connected
distributed generating system and also isolates the particular affected areas. To deliver the
power to the customer in an efficient manner the impedance values are should maintain at a
constant level. If the impedance value of any one of DG’s are varies, it affects the entire grid
connected systems. This method is based on injecting two non-characteristics harmonic
currents to the grid and the appropriate harmonic voltages are developed at the Point of
Common Coupling (PCC) and impedance is calculated. Newton Raphson method is involved
for the impedance calculation. The work is carried out under the MATLAB Environment, the
results are verified theoretically and by simulation
Keywords:
fault, distributed generating systems, isolation, injection of fault, impedance.
