Investigation on Full-Converter-Based Wind Power Plant Behavior During Short-Circuits

Transmission Line Protection Performance in the Presence of Wind Power Plants: Study on the Busbar Capacitance Modeling During Relay Testing Procedures

“…Among traditional renewable sources, wind power plants (WPPs) have been widely used in several countries, as in Brazil, where major part of the Northeast region electric power demand has been supplied by wind turbines. It has boosted researches on protection, electromagnetic transients, control, and power electronics in the presence of WPPs (Chavez et al, 2019;Costa et al, 2019;Blaabjerg and Ma, 2013). Regarding the protection of transmission lines that connect WPPs to the grid, two main challenging scenarios are often reported: 1) converter-interfaced wind power generation units result in unconventional transient and short-circuit behaviors (Chavez et al, 2019;Costa et al, 2019); 2) weak terminals are usually verified at the WPP side due to the power transformers that elevate voltages to the desired high levels at the power network side (Costa et al, 2019).…”

As these features can influence the performance of existing protection functions (Chavez et al, 2019), relays testing procedures are of great importance when wind power integration is taken into account.…”
