Available in PDF, EPUB and Kindle. Book excerpt: This monograph describes the synthesis and use of biologically-inspired artificial hydrocarbon networks (AHNs) for approximation models associated with machine learning and a novel computational algorithm with which to exploit them. The reader is first introduced to various kinds of algorithms designed to deal with approximation problems and then, via some conventional ideas of organic chemistry, to the creation and characterization of artificial organic networks and AHNs in particular. The advantages of using organic networks are discussed with the rules to be followed to adapt the network to its objectives. Graph theory is used as the basis of the necessary formalism. Simulated and experimental examples of the use of fuzzy logic and genetic algorithms with organic neural networks are presented and a number of modeling problems suitable for treatment by AHNs are described: · approximation; · inference; · clustering; · control; · classification; and · audio-signal filtering. The text finishes with a consideration of directions in which AHNs could be implemented and developed in future. A complete LabVIEWTM toolkit, downloadable from the book’s page at springer.com enables readers to design and implement organic neural networks of their own. The novel approach to creating networks suitable for machine learning systems demonstrated in Artificial Organic Networks will be of interest to academic researchers and graduate students working in areas associated with computational intelligence, intelligent control, systems approximation and complex networks.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "After decades of development, the wind energy industry is now supplying 10 to 20% of power in electric utilities. At present Doubly-Fed Induction Generators (DFIG) are one of the most widely used generators in wind farms. The research of this thesis advances the methods of controlling DFIGs by presenting: (i)a non-mechanical (sensorless) method of determining accurate rotor speed and rotor position which are essential in implementing decoupled P-Q control; (ii)a method of autonomous frequency control whereby an islanded wind farm does not have to shut down but continues to operate as standby ready to assist the utility grid in fast restoration; (iii) a method of mitigating the problem of power imbalance at the initial period of islanding by using pitch control to spill excess wind power.The thesis also examines what economical adaptation is required to make the Doubly-Fed Induction Generator, which has the advanced controllers designed for wind power application, marketable as Doubly-Fed Induction Motor. Research is based on theoretical analysis, validated by digital simulation. A prototype DFIG 5hp experimental platform, which has been built and tested, provides experimental verification to claims." --

This book was released on 2017 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Doubly-Fed Induction Generators (DFIG) are widely used nowadays for renewable energy generation. Control techniques need to be developed to match the growing DFIG wind turbine sizes and capacity. This requires better modeling verification tools of the DFIG which also bring other benefits. They can help to better increase their reliability, as well as improving the efficiency of the power output. This research mainly demonstrates the verification of DFIG electric models by identifying the parameters of operating DFIGs. The 4th order and 2nd order DFIG electric models were derived and specifically used for the parameter identification process. In order to provide the measurement input data for the parameter identification algorithm, a customized DFIG simulation model was built in MATLAB SIMULINK. By applying the Model Reference Adaptive Control (MRAC) algorithm, the electric parameters of the DFIG models have been identified with high accuracy and short convergence time. The proposed MRAC algorithm also performs well on identifying the parameters when the rotational speed changes. In the field, the measurement data can be taken from Phasor Measurement Units (PMU) to achieve the on-line identification. This identification technique can be used as an ad-hoc function block as well, that can cooperate with other DFIG control techniques, as well as provide reference information indicating the real-time operation condition of the wind- turbines.

Download or read book Variable Frequency Operation of Stand-alone Doubly Fed Induction Generator Connected to the DC System written by Manish Niraula and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research focuses on the stand-alone operation of doubly fed induction generator (DFIG) with variable stator frequency. In stand-alone configuration, the stator side is connected to a three phase diode rectifier and a stand-alone electrical load. The dc output voltage regulation is achieved by applying stator flux oriented control scheme in synchronous reference frame. The losses that occur in the power electronics components depend on the current flowing through the switches and so in the power rating of the converter. WECS based on DFIG are designed for variable speed operation. So, the main objective of the DFIG control strategy is to regulate the generator speed so that maximum amount of wind energy is extracted for the given speed of the wind. But the generator cannot be run in full speed range if the converter rating used is smaller than the rated power of the turbine. Thus, the speed range of the DFIG is determined by the converter rating and hence the slip is limited using variable frequency operation of DFIG to reduce the converter rating and extend the speed range of operation. The dc-link capacitor voltage is regulated to a constant rated value and so the stator voltage amplitude is also constant. The flux-frequency product being constant, a variation in stator flux magnitude results in a frequency variation. So, the stator frequency can be scheduled in such a way that the output power is maximized. Some simulation tests have been run during this work to find the optimal stator frequency for a fixed range of speed and used as a look up table to improve the power conversion efficiency of the whole generator system.
