This book was released on 2014 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thesis presented on addressing the modeling requirements for short circuit contributions from Type 3 wind turbine generators. This research can be used by electric utilities for transmission level protective relay coordinating using the ASPEN OneLiner software. This thesis will discuss four different short circuit modeling approaches which can be used for interconnected groups of Type 3 wind turbine generators and their implementation into a short circuit software model. These approaches' fault current outputs will be compared with the fault current results from the traditional full detail model approach. This research also sheds light on the protection practices the transmission utility can use to protect their transmission lines when interconnected with a wind turbine generating facility. The distance and differential schemes presented in this document are validated through the OneLiner software.

Available in PDF, EPUB and Kindle. Book excerpt: Short circuit study needs to be performed at the planning stage before connecting large generators with the electric grid. This study will reveal the impact of new generation on the fault levels of the grid. The fault levels will determine the rating of nearby equipment and setting of relays. However, a short circuit model of synchronous generator is well documented, such models are not adequately known for Wind Turbine Generators (WTGs). This dissertation describes detailed time domain models of all types of WTGs, commonly classified as Type 1, Type 2, type 3, and Type 4. MOdels of Type 1, 2, and 3 are validated using field data. Using these models, short circuit models are developed. Simulation and short circuit modeling of Type 2 WTG and wind farms having this type of WTGs are validated using actual field data from Mountain wind farm located in Wyoming, USA. Some insight into the selection of circuit breakers in the wind farm is also offered. A simple yet accurate equivalencing procedure for large wind farms is also proposed. This analysis also applies to Type 1 WTG. Simulation and short circuit modeling of Type 3 WTG and wind farms having this type of WTGs are developed. This model assumes that the rotor circuit is crowbarred during fault. The model is validated using actual field data from Three Buttes wind farm in Wyoming, USA. Valuable insight about the status of crowbar during faults is achieved through this model.

Available in PDF, EPUB and Kindle. Book excerpt: Protection of both the wind plant and the interconnecting transmission system during short-circuit faults is imperative for maintaining system structural integrity and reliability. The circuit breakers and protective relays used to protect the power system during such events are designed based upon calculations of the current that will flow in the circuit during the fault. Sequence-network models of various power-system components, such as synchronous generators, transformers, transmission lines, etc., are often used to perform these calculations. However, there are no such models widely accepted for certain types of wind-turbine generators used in modern wind plants. The problem with developing sequence-network models of wind plants is that several different wind-turbine generator designs exist; yet, each exhibit very different short-circuit behavior. Therefore, a "one size fits all" approach is not appropriate for modeling wind plants, as has been the case for conventional power plants based on synchronous-generator technology. Further, many of the newer wind-turbine designs contain proprietary controls that affect the short-circuit behavior, and wind-turbine manufacturers are often not willing to disclose these controls. Thus, protection engineers do not have a standard or other well-established model for calculating short-circuit currents in power systems with wind plants. Therefore, the research described in this dissertation involves the development of such models for calculating short-circuit currents from wind-turbine generators. The focus of this dissertation is on the four existing wind-turbine generator designs (identified as Types 1 -- 4). Only AC-transmission-interconnected wind-turbine generators are considered in this dissertation. The primary objective of this research is the development of sequence-network models, which are frequency-domain analysis tools, for each wind-turbine generator design. The time-domain behavior of each wind-turbine generator is thoroughly analyzed through transient simulations, experimental tests on scaled wind-turbine generator test beds, and solutions to the system dynamic equations. These time-domain analyses are used to support the development of the sequence-network models.
Download or read book Short circuit Modeling of a Wind Power Plant written by E. Muljadi and published by . This book was released on 2011 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important aspect of wind power plant (WPP) impact studies is to evaluate short-circuit current (SCC) contribution of the plant into the transmission network under different fault conditions. This information is needed to size the circuit breakers, to establish the proper system protection, and to choose the transient suppressor in the circuits within the WPP. This task can be challenging to protection engineers due to the topology differences between different types of wind turbine generators (WTGs) and the conventional generating units. This paper investigates the short-circuit behavior of a WPP for different types of wind turbines.

Book excerpt: In this thesis, the line protection elements and their supervisory elements are analyzed in context of Type 3 (Doubly Fed Induction Generator based) grid integrated wind turbine systems. The underlying converter and controller design algorithms and topologies are discussed. A detailed controller for the Type 3 wind turbine system is designed and integrated to the grid using the Real Time Digital Simulator (RTDS). An alternative to the conventional Phase Locked Loop (PLL) for tracking of rotor frequency is designed and implemented. A comparative analysis of the performance of an averaged model and the corresponding switching model is presented. After completing the Wind Turbine (WT) model design, the averaged model is used to model an aggregate 10-generator equivalent model tied to a 230kV grid via a 22kV collector. This model is a great asset to understand dynamics, and the unfaulted and faulted behavior of aggregated and single-turbine Type 3 WT systems. The model is then utilized to analyze the response of conventional protection schemes (Line current Differential and Mho Distance elements) and their respective supervisory elements of modern commercial protection relays in real time by hardware-in-the-loop simulation using the RTDS. Differences in the behavior of these elements compared to conventional power systems is noted. Fault are analyzed from the relay's perspective and the reasons for the observed behavior are presented. Challenges associated with sequence components and relay sensitivity are discussed and alternate practices to circumvent these issues are recommended.

Book excerpt: An important aspect of wind power plant (WPP) impact studies is to evaluate the short-circuit (SC) current contribution of the plant into the transmission network under various fault conditions such as single, two, and three-phase faults in different network locations. This task can be challenging to protection engineers due to the topology differences between different types of wind turbine generators (WTGs) and conventional generating units. This paper presents simulation results for SC current contribution for WTGs obtained through transient simulation. The obtained waveforms are analyzed to explain the behavior, such as peak values and rate of decay, of the WTG.
Download or read book Design Modeling and Analysis of a New Protection Scheme for Type 4 Wind Turbines written by Shashidhar Reddy Sathu and published by . This book was released on 2016 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: The short circuit behavior of the early generation wind turbines depends solely on the physical characteristics of the machine. The conventional protection schemes can be applied to provide protection to these wind farms. But the full converter based Type 4 Wind turbine generators have complex fault current characteristics which are governed by the converter controls. The control response of the WTG's during fault is not similar to that of synchronous generators. The use of relay with conventional protection schemes may cause misoperation. In this thesis an attempt is made to explain the complex converter controls and operation and various grid codes that the wind farms are expected to follow. A new protection scheme is designed based on the system operation and tested with simulation fault responses of Type 4 wind turbine in real time digital simulator. This thesis also explains the reasons that cause misoperation for using convention protection schemes.
