Different Factors Affecting Short Circuit Behavior of a Wind Power Plant

Distributed Wind Controls: A Research Roadmap for Microgrids, Infrastructure Resilience, and Controls Launchpad (MIRACL)

“…After self-start, to further energize other components in the grid such as induction motors, transformers, and AC lines, the turbine must provide the needed voltage support (inrush current during the start). It was shown previously that Type 3 DFIG-based wind plants have the ability to support large short-circuit currents, and thereby also large inrush current (Muljadi et al 2010).…”

Fault characteristics of full power inverted sources and its short‐circuit current calculation model

“…Among the existing researches, literatures [3, 4] just simulated and compared of the fault features of different kinds of wind farms without theoretical explanation. Besides, the literature [5] analysed the effect of connection mode of transformers on zero sequence current under asymmetric faults. Literatures [6, 7] assumed that inverters of renewable energy sources have limited overcurrent ability, thus current limiter is implemented which will affect the magnitude of fault current.…”

Review of Dynamic and Transient Modeling of Power Electronic Converters for Converter Dominated Power Systems

“…Additionally, numerous types of EMT models exist, each appropriate for specific stability issues. Examples of specific stability issues which become present in converter-dominated power systems (CDPS), where converter-based generation exists at both distribution and transmission levels, includes but is not limited to: a high rate of change of frequency due to low inertia [2], [6], [7], limited fault current contribution impacting protection coordination [2], [8]- [10], bi-directional power flow impacting damping of inter-area modes and transient stability margins [11]- [13], harmonic instability due to converter inner control loops [13], [14], interactions between multiple grid-connected converters [13], [15], [16], and lower frequency oscillations introduced by the phase-locked loop (PLL), particularly in weak grids with short circuit ratios less than 2 [13], [17]. An excellent review of these converterbased generation stability issues is provided in [2], [13], [14], [18].…”
