Analysis of faults on series compensated EHV transmission line in the presence of wind generation

The transient components are introduced in the extra high voltage (EHV) transmission lines during the faulty conditions. The transients may damage the power system equipments as well as may also lead to the mal-operation of the equipments utilized for a specific application in the power network. These transient components are intensified in the presence of distributed generation (DG) sources such as wind and solar power generation. Further, these transients may affect the functioning of series compensation of the lines in the presence of renewable energy sources. The analysis of faults on the series compensated EHV transmission lines in the presence of DG sources may help to design suitable series compensation as well as the generator sizes. This paper addresses the effect of power system faults on the voltage and current waveforms in the presence of wind generation and series compensated EHV transmission lines. The detailed simulation study of transmission line faults with and without series compensation in the presence of 3 MW wind power generation has been carried out in MATLAB/Simulink environment. The simulation results show the impacts of faults on the system voltages and load currents with and without series compensation of the lines in the presence of wind power generation.
