Short-Circuit Incipient Faults Detection from Single Phase PWM Inverter using Artificial Neural Network

Indian Journal of Science and Technology, 2017
Solar Photovoltaic (PV) system consists of three main parts which are PV array, PV inverter and utility grid. From the three, PV inverter is considered the weakest link in the solar PV system. Insulated Gate Bipolar Transistor (IGBT) is the most critical component in an inverter and is often blamed for the failure of inverters.

COMPARISON OF SINGLE PHASE SHORT CIRCUIT MODELLING BY USING OF ATPDRAW SOFTWARE AND IEC PROCEDURES [PDF]

Proceedings CIRED24
Increasing trends of energy consumption and urban constraints in construction of new transmission/distribution substations are indications of bigger short circuit currents on busbars and overhead lines (OHL). OHLs are commonly equipped with Optical Power Ground Wire (OPGW), which has its limitations based on short circuit withstand heat impulse—heat ...
