6 FAQs about [Short-circuit torque of solar generator set]

What is the short circuit current in power systems?

INTRODUCTION The short circuit current in power systems is still dominated by classical synchronous generators of conventional large scale coal or nuclear power plants. As a result of the everincreasing share of renewable energy sources the short circuit current in the future will differ from the status quo.

How will short circuit current change in the future?

As a result of the everincreasing share of renewable energy sources the short circuit current in the future will differ from the status quo. The fast control of the power electronics in wind and photovoltaic power conversion systems has the capability to control the current injection during balanced as well as unbalanced grid faults.

How does grid integration affect short circuit capacity?

The grid integration of renewable energies is more and more influencing the short circuit capacity (SCC) of power systems all over the world. The behavior of renewable energy sources, e.g. wind or solar energy, is different from that of classical synchronous generators during symmetrical or unsymmetrical short circuits.

Why are PV inverters able to supply more short circuit current?

In principle the PV inverters are able to supply more short circuit current during fault scenarios than only 1 p.u. reactive current due to current reserve margin of the inverter system. The control is able to limit the current injection during faults to the nominal but also to an overload current limitation of the generation system.

Who are the authors of a short-circuit analysis of an isolated generator?

Ch. G. Kaloudas, P. N. Papadopoulos, T. A. Papadopoulos, A. G. Marinopoulos, G. K. Papagiannis, “Short-Circuit Analysis of an Isolated Generator and Comparative Study of IEC, ANSI and Dynamic Simulation,” presented at the MedPower 10 Conf., Agia Napa, Cyprus, 2010.

How are short-circuit currents calculated?

Abstract— The calculation of short-circuit currents is mostly based on the methodology of the international standards IEC-60909 and ANSI / IEEE C37.010.1979. This methodology, although it utilizes simple procedures and various assumptions, usually provides satisfactory results.
