Title

TECHNICAL ISSUES FOR PV SYSTEM CONNECTED GRID

Abstract

: Technical issue pertaining to the LLLG (Line-Line-Line-Ground) fault in a photovoltaic (PV) connected grid system. A specific reference is made to a 100-kW PV array that is connected to a 25-kV grid. The system includes components such as a 5-kHz DC-DC boost converter, a 10-kvar capacitor bank, and a 100-kVA 260V/25kV three-phase coupling transformer. The grid itself consists of a 25-kV distribution feeder and a 120 kV equivalent transmission system. The LLLG fault, which refers to a three-phase line-to-line-to-line-to-ground fault, is a critical concern in PV grid-connected systems. This fault can lead to abnormal conditions such as voltage imbalances, increased harmonic content, and potential damage to the system components. Therefore, understanding and mitigating the LLLG fault is essential for the reliable operation of PV grids.Several research studies and industry reports have addressed the LLLG fault issue in PV-connected grids. These references provide insights into fault detection techniques, fault current analysis, and protective measures to prevent or minimize the impact of LLLG faults. By incorporating advanced fault detection algorithms, protective relays, and appropriate grounding strategies, the adverse effects of LLLG faults can be mitigated, ensuring the stability and resilience of the PV grid system.
