DIRECT POWER CONTROL OF DFIG IN A WIND TURBINE TO IMPROVE DYNAMIC RESPONSE Objective________________________________________ This paper presents a direct power control (DPC) strategy for a doubly-fed induction generator (DFIG)-based wind energy generation system. The strategy is based on the direct control of stator active and reactive power by selecting appropriate voltage vectors on the rotor side. The proposed direct power control (DPC) method produces a fast and robust power response without

Electrical Components of Shop Unit Electrical for HVACs Southern Technical College Abstract A working overview of our Goodman Package Units located in the lab. The overview will show comprehensive knowledge of the electrical and electronic components associated with our lab equipment. Electrical for HVACs The electrical systems of an air conditioning unit are easier to understand if a technician breaks the complex schematic into individual circuits. This will provide an efficient method

Siemens is a leading technology business and one of the largest electrical and electronics engineering companies in the world. In the UK, it employs over 20,000 people and is in the top three electrical and electronics companies in the world. It has been a pioneer in innovation since 1843 when Siemens installed the first street light in Godalming, Surrey. In 2006, Siemens UK invested over £74.4 million on research and development. The company designs and manufactures products and services for

Proximate Cause’ is defined as “The active, efficient cause that sets in motion a chain of events, which brings about a result, without the intervention of any new or independent force” Life itself is full of events, sometimes occurring independently of each other or as a result of another. The principle, proximate cause identifies for insurance purposes, which event is the probable cause of a particular event, leading to a loss and whether this event is insured. Usually, the first and last

earlier life, I never thought I would come to US for my master of engineering, work as an electrical engineer at Force10networks (it was acquired by DELL recently), and now pursue an MBA. My past accomplishments that have prepared me for the W.P. Carey MBA include teaching mathematics in Taiwan, coming to US to improve myself, earning my engineering masters at the University of Arizona, and working as electrical design engineer at force10networks. Before I came to US, I had taught mathematics

ABSTRACT The mechanical properties of composite materials are strongly dependent on micro structural parameters of the system. The evolution of microstructure depends largely on the cooling rate during phase change. Though the microstructure evolution depends on many process parameters, the final structure is decided by cooling conditions during solidifications. The mould material has a decided effect on the structure formation. The use of end chills during casting not only favours directional solidification

Experiment 7 – October 9, 2012 RLC Resonance Purpose Study resonance in a series resistor-inductor-capacitor (RLC) circuit by examining the current through the circuit as a function of the frequency of the applied voltage. Theory The amplitude of the AC current (I0) in series RLC circuit depends on the amplitude of the applied voltage (V0) and the impedance (Z). Where XL =ωL (inductive reactance), XC = 1/ωC (capacitave reactance), R (resistance), angular frequency ω = 2πf (f is linear

LDRs and Thermistors LDRs are light dependent resistors that are often used in circuits where it is necessary to detect the presence or the level of light. A light dependent resistor is a component that is sensitive to light; therefore when light falls upon it the resistance changes. The value of resistance of the LDR is subject to change over many orders of magnitude when the value of the resistance falls as the level of light increases. It is fairly simple to understand the basics of how an
