This paper presents a short-circuit analysis of grid-connected photovoltaic (PV) power plants, which contain several Voltage Source Converters (VSCs) that regulate and convert the power from DC to AC networks. A different methodology has been adopted in this paper for short-circuit calculation.
Inverter power switch short-circuit protection is fully integrated. A desaturation detection circuit is embedded in both the high- and low-side output stages and monitors the IGBT collector-to-emitter voltage by means of an external high voltage diode.
This traditional equivalent has failed to represent the power converters' control mode in the studied system . The IEC 60909 standard established that converter-based generating units can be modeled as current sources for short-circuit calculation , , .
In particular, in the calculation following the IEC 60909 standard, each PV inverter is modeling as current source that inject purely reactive current with the full capacity, . The obtained results are shown in Fig. 7 for comparison.
Short-circuit protection on low- and medium-power inverterized motor drives is becoming essential to comply with safety standards. However, the implementation of such a feature can
