Improved low-voltage-ride-through capability of fixed-speed wind turbines using decentralised control of STATCOM with energy storage system
(INST ENGINEERING TECHNOLOGY-IETHERTFORD, 2012)
The design and implementation of a new control scheme for reactive power compensation, voltage regulation and transient stability enhancement for wind turbines equipped with fixed-speed induction generators (IGs) in large ...
Otherwise identical particles with differing, fixed speeds demix under time-reversible dynamics
(American Physical Society, 2020-06-18)
In recent years situations where elsewise identical particles demix when different degrees of freedom do not thermalize have become a research focus in nonequilibrium statistical mechanics. The majority of these models are ...
Desempenho comparativo entre compressores rotativos de parafuso com velocidade fixa e variável
(Universidade Federal de Santa MariaCentro de Tecnologia, 2014-12-06)
The use of compressed air in industries is indispensable, regardless of its size. One of the major problems occurring in the use of compressed air is a large variation in network load with various alternations of high and ...
An experimental verification of newton's second law
(2013-06-01)
We describe an experimental procedure to probe the validity of Newton's second law. The experimental arrangement allows us to accelerate a glider on an air track by means of forces that are both steady and known. We also ...

Robust STATCOM control for the stabilisation of fixed-speed wind turbines during low voltages
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
This paper presents a robust voltage control scheme for fixed-speed wind generators using a static synchronous compensator (STATCOM) controller. To enable a linear and robust control framework with structured uncertainty, ...
Un algoritmo óptimo para la aproximación de la velocidad angular utilizando encoders
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2013)
En este artículo se propone un algoritmo nuevo, el cual utiliza las señales provenientes de un encoder incremental para aproximar la velocidad de giro de un eje. Este algoritmo elimina las oscilaciones que aparecen en los ...
