Coursework: Operation and control of Doubly-Fed Induction Generator Wind Turbine (DFIG-WT)
Wind turbines are playing a major role in renewable power generation in the UK. The electrical generator system is one of the core parts in a wind turbine. Using information gathered from a minimum of 8 different sources/references (e.g. books, journal papers, company websites, etc...), write a report that identifies the operating principles, characteristics and application of the DFIG-WT. Use any appropriate/available software (e.g. MATLAB) wherever applicable within your report. Your report should discuss the following points (aided with solid graphs, plots, tables, and numerical data):• Introduction to the structure and operation of a generic wind turbine system.• The major types of electrical generator used in wind turbines and their typical ratings.• The operational principles of Permanent Magnet Synchronous Generator (PMSG).• The operational principles of Double-Fed Induction Generator (DFIG).• Provide comments and concise explanations on the strengths and weaknesses of PMSG and DFIG in terms industrial implementations.• Operation of the DFIG-WT in super-synchronous and sub-synchronous modes as well as the point of zero slip.• Fault ride through capability of DFIG-WTs and its operation under AC faults.
The report should be limited to 2500-3000 words. The report should provide evidence of the following:• Professional presentation and structure of information• Evidence of background reading and correct use of relevant reference material, sources used should be identified in the manner shown in IEEE journals• Technical description and critical evaluation of the power electronics and its application• Relevance and accuracy of arguments• Relevant conclusions
Calculate a value for RC1 to achieve a mid-band voltage gain of approximately -10. Determine the bias conditions for the transistor (i.e. collector voltage, base voltage, emitter voltage, collector current and emitter current)
Calculate: Critical frequency for the input low pass network, and the output low pass network, estimate the values for Cbe, Cjc, Cbc, and Cje. Concider the resistance of the signal sourceRs to be equal to the 1 ohm resister in series with the source.
Design a diode voltage regulator to supply 1.5V to a 150-ohm load. Use two diodes specified to have a 0.7-V drop at a current of 10mA. The diodes are to be connected to a +5-V supply through a resistor R.
Water is being heated in a vertical piston-cylinder device. The piston has a mass of 15 kg and a cross-sectional area of 120 cm^2. If local atmospheric pressure is 99.5 kPa, determine the temperature at which the water will start boiling.
An electron describes periodic oscillations in the direction of the axis "z" with amplitude of 1 nm (nano meters) around a ring, if the ring has a total charge of 100e with a radius of 50 nm (nano meters) . Determine load osilacion and maximum spe..
Given an analog signal with a maximum positive voltage of 3 volts and an 10-bit analog to digital converter, what will be the quantized value of an input voltage of 1.70 volts
For each proposed approach, describe the predictive model that will be built, how the model will be used by the business, and how using the model will help address the original business problem
If the receiver equivalent noise bandwidth is 65 MHz, and the signal to strength at the antenna connection to the RF band pass filter is 7pW (710-12W), calculate the signal to noise ratio in dB at the receiver output to the demodulator.
Find an average value of the periodic.
Apply the law of conservation of mass to an element in a polar coordinate system and obtain the continuity equation for a steady, two-dimensional, incompressible flow.
A concrete table column-support with the profile shown in the accompanying figure is to carry a load of approximately 500 lb.
The NF (dB) is defined as 10log(SNRin/SNRout) - in the unit of dB. If we are given the values of SNRin and SNRout in dB unit, how do we calculate NF (dB) in terms of dB, and how do we calculate NF in term of a pure ratio
