| Summary: | The project of fault studies in power system network solar system incorporated is conducted at llkV bus bar to determine the effect of fault by finding out the characteristic of voltage versus time waveform of the grid-connected PV system, 11 kV bus bar and three phase load during fault condition by using Matlab/Simulink. Furthermore, to determine which type of fault that cause most severe damage to this system. Other than that, since the main supply of this system is from PV, one of the objectives is to obtain the behavior of PV module by generating the I-V and P-V characteristics curve based on BPSX510 parameter. Besides that, the grid-connected PV system model with 415Vrms output voltage was model. PV system is interfaced to the distribution network through boost converter, two level three phase inverter and the output voltage is step-up using 0.415/11 kV Dllyn transformer. Then, this distribution network is used to supply 415Vrms load through llk/0.415 kV YNdl step-down transformer. The type of fault that is being conducted to the 1 lkV bus bar such as singleline to ground fault, double line to ground fault and line-line fault. The output voltage at grid-connected, llkV distribution network and load was measured and analyzed. The fault that cause severe damage to system is the double line to ground fault. |
