“…Although the effect of grid-following controls on the incumbent protection system has been studied for a number of protection mechanisms (Martinez et al 2011;Walling, Gursoy, and English 2012;IEEE PES 2013;Farantatos et al 2013;Fischer and Mendonca 2012;Howard 2013;Howard, Liang, and Harley 2014;Karaagac et al 2015;Kocar et al 2014;, and it has been determined that high penetrations of renewable generation result in potential incorrect operation of traditional protection mechanisms (EPRI 2014; EPRI 2017a; EPRI 2017b; EPRI 2017c; Seguin et al 2016), the effect of grid-forming inverters on protection is fundamentally different than that of grid-following inverters and has not been extensively studied. The short-circuit currents from grid-forming inverters can be equivalent to synchronous generation but are normally constrained to 4-6 p.u.…”

“…Main share of WTGs are variable-speed WTGs, especially type 3 and type 4. Therefore, these two types have been widely analysed in the literature [4], [5]. WTGs, as well as other distributed generation units, might affect operation of overcurrent relays (OCRs).…”

This paper discussed different short-circuit impedance models for type 3 and type 4 wind turbine generators. IEC and IEEE-PES models are either simplified or they require additional data. The proposed model is given by a non-linear dependency of the short-circuit impedance and voltage on the medium voltage side of the unit transformer. Furthermore, the proposed model, as well as the constant impedance-based model were used for timing coordination of overcurrent relays in a radial 6-bus network. The obtained results show that the constant impedance-based model overestimates short-circuit currents. Consequently, selectivity of individual overcurrent relays might be questionable.

“…These EMT-type models can emulate the time-domain fault response of an actual WTG. Taking these detailed models as references, phasor domain models were developed and an iterative algorithm to integrate these models into protection tools based on steady-state solvers was proposed [7][8][9]. The phasor models reproduce the steady-state short circuit behavior of detailed models.…”

A challenge faced by protection and planning engineers is the development and validation of accurate wind turbine generator (WTG) models to study the impact of increased wind integration on system protection. This paper is on the experimental validation of a generic electromagnetic transient-type (EMT-type) model of aggregated WTGs or wind parks suitable for transient studies.The phasor domain equivalent of the generic model, suitable for protection tools based on steady-state solvers, is also considered. The model has been validated using two sets of actual relay records for the fault response of two wind parks consisting of Type-III WTGs and connected to 115 kV and 230 kV transmission systems. The objective is to show that the generic model can reproduce the actual fault response in simulations, and protection engineers can obtain accurate models of wind parks using fault records. A distinctive characteristic of a WTG is its substantially different negative sequence fault current contribution compared to a synchronous generator. The paper shows that the generic model provides enough options to reproduce the negative sequence behavior and hence is suitable for fault studies involving negative sequence-based protection.
