systems all over the world. Large wind farms are going to be connected to electrical networks which have been
series compensated to guarantee the safe and stable transmission of bulk power. However a series compensated
power system may encounter with a very important problem known as subsynchronous resonance (SSR). Flexible ac
transmission systems (FACTS) controllers are widely applied to mitigate subsynchronous oscillations.,2017-06-25 13:55:32,下载2次
06547878.rar - This study presents wind turbine converter stability analysis of wind farms in frequency domain. The interaction
between the wind turbine control system and the wind farm structure in wind farms is deeply investigated. Two wind farms
(i.e. Horns Rev II and Karnice) are taken into consideration in this study. It is shown that wind farm components, such as
long high-voltage alternating current cables and park transformers, can introduce significant low-frequency series resonances
seen from the wind turbine terminals that can affect wind turbine control system operation and overall wind farm stability,2017-06-25 13:54:37,下载1次

05448528.rar - s a clean renewable energy, wind energy draws more
and more attention around the world. In case of high wind speed
or low speed but substantial installed wind power capacity, wind
turbine generators (WTGs) will take the place of traditional
power plant partly. Under the circumstance, the transient
stability will change. Therefore, in this article, the synthetical
dynamic model of WTG is introduced first, and on the basis of it,
the article focus on the comparison of transient stability

05955931.rar - This paper proposes a Flexible D-STATCOM (Distribution STATIC Compensator) and its new
controller system, in IEEE 13-bus industrial distribution system, that be able to both mitigate all types of series
faults (open-circuit or open conductor faults) and operate as a Distributed Generation (DG), when it supplies power
to sensitive loads while the main utility source is disconnected (i.e. it is under islanded operating condition). Thus
D-STATCOM operates same as a Flexible DG (FDG) and consequently, it is called Flexible D-STATCOM (FDSTATCOM). In this paper, the 12-pulse FD-STATCOM configuration with IGBT is designed and the graphic based
models of the FD-STATCOM are developed using the PSCAD/EMTDC electromagnetic transient simulation
program. The reliability and robustness of the control schemes in the system response to the voltage disturbances
caused by series faults and islanded operating condition are obviously proved in the simulation results.,2017-06-25 13:33:19,下载9次

frequency (0.2 Hz to 2.0 Hz) oscillations. This type of
instability can endanger system security and limit power

4587a386.rar - Transformer is one of the costliest apparatus in an
electrical power supply network which play vital role in an
electrical power system. It is expected that all transformers
installed in a substation must function optimally under normal
as well transient conditions. Their satisfactory performance of
transformers can be ensured by making use of latest trends in
condition based monitoring. This helps not only in providing
interruption free electricity supply but also help in enhancing
attain prolonged residual life and hence capital management of
the utilities. Forecasting transformer costs by its manufacturer
and industrial companies has always been an area of interest

gain scheduled proportional-integral (FGSPI) controller as the
supplementary controller for load frequency control (LFC) of
two-area interconnected power system with reheat type thermal
unit of equal capacity in each area. The dynamic response has
been studied for 1% step load perturbation in area-1. The
proposed FGSPI controller is compared against conventional
proportional-integral (PI) controller and state feedback linear
quadratic regulator (LQR) controller using settling times,
overshoots and undershoots of the tie-line power and frequency
deviations as performance indices. Comparative analysis
indicates that the proposed intelligent controller gives better
performance than conventional controllers.,2017-06-25 13:25:04,下载4次
