Available in PDF, EPUB and Kindle. Book excerpt: The increasing share of renewable energy resources in electricity generation requires reassessment of protection systems. This is due to the fact that renewables are often electronically coupled to the grid and their behavior under transient conditions is different from the behavior of power plants generating power using classical synchronous generators. The behavior of electronically coupled generators depends on the controllers of their converters, and in principle, their precise simulation under short-circuit conditions is possible using dynamic or transient tools which allow detailed modeling of controllers. However, protection and short-circuit software packages used by practicing engineers depend on steady-state solution engines built in phasor domain. The main objective of this thesis is to develop steady-state phasor models of wind and solar parks that provide their current contribution under steady-state short-circuit conditions. The steady-state models are developed for type-III and type-IV wind turbine generators. Negative sequence control and park controller options are also considered. The Type-IV model can also be used for modeling solar plants since both sources are connected via full converters. The steady-state models are validated using a detailed time-domain model that is developed in EMTP-RV software with the feedback of a leading European manufacturer of wind turbines. The phasor models take into account the behavior of converter conrollers and various control strategies associated with it. For large-scale wind parks connected to high voltage networks, the point of control is located at the point of interconnection of the park. The control strategies act on voltage, reactive power or power factor. In addition to these three control modes, a fault ride through mode is also available to support voltage during fault conditions. A current limiter protects the converters against overcurrent, and operates with P- or Q-priority. This limiter is indispensable but introduces a non-linear behavior. The phasor models take into account the natural negative sequence response of the wind turbine generator with two levels of precision if the controllers are not set to regulate negative sequence : simplified and detailed. Higher precision requires more details about the controller, such as the gains of the inner loop proportional-integral controller.

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.

This book was released on 2010 with total page 8 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2020-03-05 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are a number of books in the market about wind energy, turbine controllers, modelling and different aspects of integration of Wind Farm Power Plants ( WPP) to grids. But none of these books meets the expectations of design and field engineers/technicians to address directly the setting and design philosophy of different Intelligent Electronic Devices (IED) of WPP networks. This book provides practical applications of numerical relays for protection and control of different parts of onshore & offshore WPP network namely wind turbine generator, collector feeder and EHV interconnection transmission line to grid. In addition required changes to existing special protection system (SPS) and run-back scheme by adding a new WPP are discussed. The topology and characteristics of WPP networks are different from convectional one for both onshore and offshore WPP. In addition the fault current contribution from wind farm generators are low (1.1-1.2 pu). These causes significant challenge for setting and design of IEDs of WPP in order to meet the common industry practice requirement with respect to reliability, sensitivity, stability, security and grading coordination. The author believes that this book may be unique with respect to addressing these challenges and provision of the mitigation techniques to rectify the deficiencies of existing industry practice which otherwise have not been discussed for real systems in any other book. The content of this book have been successfully applied in the field for various WPPs projects and consequently can be used as a practical guideline for implementation for future projects. The content of the book covers Principal of Operation of WPP , Modelling of different com ponents of WPP, Short Circuit current and voltage characteristics of different type of wind turbine generators, Setting and Design of Protection systems of WPP Network , Design of Control systems of WPP, Lightening and Overvoltage Protection of WPP and Analysis of Disturbance on the WPP networks
