dc.description.abstract | This thesis presents an assessment of voltage sags when faults are happened in the 115 kV
transmission line of the Provincial Electricity Authority (PEA) when distributed generation (DG) is installed
in the system. The computer program PSCAD/EMTDC (Power Systems Computer Aided Design / Electromagnetic Transient in DC system) version 4.2 is applied to provide electrical parameters for the modeling and simulation and to analyze the fault occurred which resulted in voltage sag.
Test results from PSCAD/EMTDC show the values of voltage sag when 5 types of fault are occurred (Single Line to Ground Fault, Double Line to Ground Fault, Three Phase to Ground Fault, Line to Fault and Three Phase Fault). For all cases, the value of root mean square voltage before fault is 100% or 1.0 pu. It can be seen that for both radial line and closed circuit, when DG are installed in the system, the value of phase to ground RMS residual voltage and phase to phase RMS residual voltage at the bus of Bang-pa-in 2 substation are more than the values in case of the system without DG. | en_US |
