“…As active power, reactive power, and voltage magnitude-phase state exist in every device, the characteristics of a variety of grid-connected devices, such as VSCs, SGs, and induction machines, can generally be described and modeled from this perspective. Take the wind turbine model as an example, differ to the wind turbine models for power system stability analysis in time-domain [32][33][34], this modeling method can intuitively reflect the physical relation between the power balancing and states. In this way, the essential difference in characteristics among different devices can be recognized.…”

Power balance, including active and reactive power, between the system supply and the demand from induction motor loads is a potentially necessary condition for system stable operation. Motion of system states depends on the balancing of active and reactive powers. Therefore, this paper proposes an induction machine model in electromechanical timescale from a power balancing viewpoint, in which the induction motor load is modeled as a voltage vector driven by power balancing between the system supply and the demand from induction motor load, so as to describe the dynamic characteristics of induction motor loads in a physical way for power system dynamic analysis. Then a voltage magnitude-phase dynamic analysis with the proposed induction machine model is constructed. Based on the voltage magnitude-phase dynamic analysis, the characteristics of grid-connected induction motor loads are explored, and the instability mechanisms of grid-connected induction motor loads induced by a large disturbance are discussed. It is shown that the dynamic behavior of grid-connected induction motor loads can be described as the dynamic process of the terminal voltage vector driven by coupled active and reactive power balancing in different timescales. In this way, the dynamic behavior of induction motor loads in terms of voltage magnitude-phase dynamics and its physical characteristics are clearly illustrated. Time-domain simulation results are presented to validate the above analyses.

“…It is mainly commanded by an active and a reactive current signal provided by the control system. Moreover, the corresponding IEC Standard divides the Type 3 generic model into two types depending on the Fault Ride-Through (FRT) solution adopted [5]: (i) Type 3A, with no protection system to avoid the disconnection of the wind turbine under voltage dips [27]; (ii) Type 3B, including a crowbar protection system to avoid over-currents under voltage dips, thus preventing power converter damage. In the generic Type 3B model, this crowbar system multiplies the current references of the generator by zero for a certain period of time, when the variation of the voltage goes beyond a certain limit [18].…”

“…However, conventional electromagnetic transients simulation (EMTS) models proposed by wind turbine manufacturers fail to satisfy the current needs demanded by Transmission System Operators (TSO) for these power system stability analyses; mainly due to the models being complex, highly detailed and generally confidential. In fact, these manufacturer models usually simulate the behavior of all of the internal components of the wind turbine, and hence, a large number of parameters is required to achieve accurate simulations, as well as high computational time costs or even specific software for their simulations [4,5]. Therefore, it would be desirable to propose efficient and flexible simulation models that respond to TSO requirements [5,6].…”

Generic Type 3 Wind Turbine Model Based on IEC 61400-27-1: Parameter Analysis and Transient Response under Voltage Dips

et al. 2017

This paper analyzes the response under voltage dips of a Type 3 wind turbine topology based on IEC 61400-27-1. The evolution of both active power and rotational speed is discussed in detail when some of the most relevant control parameters, included in the mechanical, active power and pitch control models, are modified. Extensive results are also included to explore the influence of these parameters on the model dynamic response. This work thus provides an extensive analysis of the generic Type 3 wind turbine model and provides an estimation of parameters not previously discussed in the specific literature. Indeed, the International Standard IEC 61400-27-1, recently published in February 2015, defines these generic dynamic simulation models for wind turbines, but does not provide values for the parameters to simulate the response of these models. Thus, there is a pressing need to establish correlations between IEC generic models and specific wind turbine manufacturer models to estimate suitable parameters for simulation purposes. Extensive results and simulations are also included in the paper.

“…The increment in size of modern wind turbines (WT) and the new growth in offshore developments represent a challenge with regards to the economic viability of wind energy in terms of reliability and availability and, hence, the operation and maintenance (O&M) activities they involve [1,2]. Traditionally, a combination of preventive and corrective maintenance strategies has been implemented [3].…”

Abstract:The goal of the present paper is to achieve the diagnosis of an in-service 1.5 MW wind turbine equipped with a doubly-fed induction generator through current signature and vibration analyses. Real data from operating machines have rarely been analysed in the scientific literature through current signature analysis supported by vibrations. The wind turbine under study was originally misdiagnosed by the operator, where a healthy component was replaced and the actual failure continued progressing. The chronological evolution of both the electrical current and vibration spectra is presented to conduct an in-depth tracking of the fault. The diagnosis is achieved through spectral analysis of the stator currents, where fault frequency components related to rotor mechanical unbalance are identified. This is confirmed by the vibration analysis, which provides insightful information on the health of the drive train. These results can be implemented in condition monitoring strategies, which is of great interest to optimise operation and maintenance costs of wind farms.
