Available in PDF, EPUB and Kindle. Book excerpt: Industrial facilities connected to power transmission systems typically draw large amount of power and have complex dynamic responses to system disturbances. Traditional load modeling approaches cannot establish adequate dynamic models especially for future industrial facilities in power systems planning studies. In this thesis, a new concept, the template-based load modeling technique along with template scaling and model equivalence algorithms, is proposed to address this issue. This method requires minimal user input and can be implemented in a database program for a wide variety of industrial facilities. Oil refinery facilities are used as an example to illustrate the proposed technique. Variable frequency drives (VFDs) are increasingly used in industrial facilities, however, dynamic models for motor drive systems suitable for power systems dynamic studies are not available. Voltage sags occur when power systems experience short-circuit faults, which is typically the starting point of power systems dynamic simulation. VFDs will trip when they experience a relatively large voltage sag (>20% - 30% voltage drop). As a result, there is no need to include VFDs in dynamic studies. Based on the finding, a simple procedure to determine if a VFD needs to be included for dynamic studies is proposed in this thesis. When VFDs experience mild voltage disturbances and are able to ride through, the equivalent dynamic model for motor drive systems is proposed. These models are created by the linearization approach, voltage dependence and frequency dependence are both considered. Dynamic models for VSI and cascaded inverter drives and their induction motor loads are developed. Aggregation algorithms for motor drive systems are proposed to achieve load equivalence facility wide. A generic dynamic load model structure covering all types of commonly used loads including motor drive systems is proposed for industrial facilities. A procedure is provided on how to obtain the final load model, which is tailored from the generic structure based on load types practically involved in an industrial facility of interest.

This book was released on 2010-06-30 with total page 601 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been growing interest in industrial systems, especially in robotic manipulators and mobile robot systems. As the cost of robots goes down and become more compact, the number of industrial applications of robotic systems increases. Moreover, there is need to design industrial systems with intelligence, autonomous decision making capabilities, and self-diagnosing properties. Intelligent Industrial Systems: Modeling, Automation and Adaptive Behavior analyzes current trends in industrial systems design, such as intelligent, industrial, and mobile robotics, complex electromechanical systems, fault diagnosis and avoidance of critical conditions, optimization, and adaptive behavior. This book discusses examples from major areas of research for engineers and researchers, providing an extensive background on robotics and industrial systems with intelligence, autonomy, and adaptive behavior giving emphasis to industrial systems design.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this thesis is to introduce widespread dynamic load models to the United States Eastern Interconnection 2030 power grid model to help improve its accuracy and capabilities. Currently, all loads in the system are represented by static load models that are unable to capture load phenomenon associated with induction motors. Chapter 1 will provide a general introduction to load modeling by discussing popular static and dynamic load models available. This chapter will also introduce the simulation test case used in Chapter 2 to Chapter 4. In Chapter 2, the complex load model parameters are developed and applied to 28,500 loads in the Eastern Interconnection model and the impact to frequency response is discussed. Buses with large differences in frequency nadir when static or dynamic load models are applied to the system and a bus with a representative response are presented for reference. Snapshots from a movie illustrate the frequency map distribution for the Eastern Interconnection. Chapter 3 is a sensitivity study of the complex load model for certain parameters. The induction motor, constant power, discharge lighting, and static load components of the complex load model are studied. The study metrics are the frequency nadir, settling frequency, and rate of change of frequency for the system average response and a single bus. Chapter 4 validates the developed model for real events recorded by the FNET/Grideye system. The accuracy of the dynamic load model is compared to the current static load model. Chapter 5 discusses the process to develop load models for a utility in the Eastern Interconnection using a bottom-up approach. The developed models are studied for several cases and validated.
