IEEE2008_2.rar - This paper proposes a wind speed estimation based
sensorless maximum wind power tracking control for variable-
speed wind turbine generators (WTGs). A specific design of
the proposed control algorithm for a wind turbine equipped with
a doubly fed induction generator (DFIG) is presented.,2012-02-14 18:27:00,下载117次
viewcontent.rar - Wind turbine generators (WTGs) are usually
equipped with mechanical sensors to measure wind speed and
turbine shaft rotating speed for system monitoring, control, and
protection. The use of these sensors increases the cost and
hardware complexity and reduces the reliability of the WTG
system. This paper proposes a novel real-time speed estimation
algorithm for wind turbines equipped with doubly-fed induction
generators (DFIGs).,2012-02-14 18:24:41,下载33次
modeling-of-upqc.rar - Unified power quality conditioners (UPQCs) allow the mitigation of voltage and current
disturbances that could affect sensitive electrical loads while compensating the load reactive power.
This paper deals with unified power quality conditioner (UPQC), which aims at the integration of
series-active and shunt-active power filters.,2012-02-14 18:21:54,下载290次
srfc.rar - This paper presents a new synchronous-referenceframe
(SRF)-based control method to compensate power-quality
(PQ) problems through a three-phase four-wire unified PQ conditioner
(UPQC) under unbalanced and distorted load conditions.
The proposed UPQC system can improve the power quality at the
point of common coupling on power distribution systems under
unbalanced and distorted load conditions.,2012-02-14 18:20:05,下载116次
hp-upqc.rar - An ideal AC power transmission is pure sinusoidal, both its voltage and its current. With
the increasing production of modern industry, more and more power electronic equipments
are used and cause serious current distortion because of open and close of power electronic
devices. Harmonic, a measurement of distorted degree of voltage or current, reflects the
deviation from sinusoidal wave.,2012-02-14 18:18:00,下载67次
thesis_new_final.rar - The need for renewable energy sources is on the rise because of the acute energy crisis in the
world today. India plans to produce 20 Gigawatts Solar power by the year 2020, whereas we
have only realized less than half a Gigawatt of our potential as of March 2010. Solar energy is a
vital untapped resource in a tropical country like ours. The main hindrance for the penetration
and reach of solar PV systems is their low efficiency and high capital cost. In this thesis, we
examine a schematic to extract maximum obtainable solar power from a PV module and use the
energy for a DC application.,2012-02-14 17:58:00,下载81次
