dhb Aeron Speed Women's Bib Shorts - RadialAn evolution of dhb's popular Aeron Speed Women's bib shorts, this newer version brings aero gains to your everyday kit. dhb Aeron Speed is dhb's answer to 'Everyday Aero'.Taking key learnings from dhb’s Pro level range, Aeron Lab, Aeron Speed is the balance of aero gains and comfort. It fits close to the skin but doesn’t require you to be built like the pros. These dhb Aeron Speed bib shorts are an updated version from the brand. Taking full advantage of the feedback taken from dhb’s 2018 season with UCI Continental Team, Canyon Eisberg, these bib shorts benefit from input from the pros but retain the ethos of the Aeron collection- all-day comfort.The shorts use Wind-Tunnel tested fabrics from industry leaders, Shoeller on the outer leg. The textured fabric creates a disruptive area where it has the most impact when in contact with the wind and air, increasing aerodynamics.

The need to diversify power generation sources, increase security of supply, incorporate sustainability in energy sources and reducing fuel usage and emissions has significantly led to the integration of variable renewable energy sources such as wind to power grids globally. Kenya, for instance, targets to increase wind power generation to 2,000 MW by 2031. However, increased integration of wind power into a grid necessitates the need to update unit commitment and operating reserve algorithms since wind power is highly variable, intermittent and non-dispatchable. In this book, the effects of increased wind power generation on the power system spinning reserve resource requirements were analyzed. Simulations for this research were conducted in MATLAB/Simulink environment. Monte Carlo Simulations were performed by use of the Unit Commitment formulation method and a probabilistic approach so as to analyze the amount of spinning reserve resource required and the optimal cost of operation for a model having three different levels of wind power generation: 20MW, 40MW and 60MW. Finally, the spinning reserve resource requirements were quantified for the three different levels of wind power

The theoretical work describes how the dynamic characteristics of slender bridges under wind action can be improved through the use of controlled actuators. First, models for the aerodynamic forces are introduced that are based on linear time-invariant transfer elements. Rational function approximations of the aerodynamic transfer functions allow for force representations with state-space models. Two matrix-based rational function approaches are applied. Their suitability is limited for bridge cross sections. For an evaluation of the approximation quality, several parameter studies are conducted. In the next step, a cable-stayed bridge is introduced as an example of a slender bridge structure. Two different spatial discretisations with element-wise and global shape functions are applied for modelling this bridge. The aeroelastic system as the combination of aerodynamic forces and the bridge structure is described in terms of a state-space model. Stability and transfer behaviour, the most important characteristics of the aeroelastic system, are theoretically investigated. Emphasis is laid on the effect of the rational function approximations on the quality of the results. Reaction wheels, control moment gyroscopes, and aerodynamically effective flaps are employed as actuators. The state-space model of the aeroelastic system is extended in order to incorporate these devices. When the actuator motions are controlled in a closed loop, the system response to disturbances can be attenuated. A particular focus of the work is on finding fundamental limits for the stabilisation of the actuator-extended aeroelastic systems. Furthermore, the performance of the controlled system in a turbulent wind field is compared for the different types of actuators. In the last steps, the effect of state observers is investigated, a disturbance feedforward is analysed, and the feasibility of an integral control is explored.

The aim of this book is to provide insight into the development of an integrated modeling method for wind turbines using various software packages. A Wind Turbine (WT) can be regarded as a Wind Energy Conversion System (WECS) consisting of electrical, mechanical, aerodynamic, power electronic, and control components. Thus a full-scale model of a WT system should incorporate various phenomena such as electrical, mechanical, and aerodynamic effects, especially when the WT is connected to the grid. In this book, after a review of basic WT concepts and software tools, a simulation structure is proposed for studying WTs. It integrates the mechanical and electrical components of a WECS by utilizing commonly used software tools. Based on the simulation structure, a model for a three-bladed WT with a doubly-fed induction generator is developed that is used to investigate the impact of voltage sag on the wind turbine tower vibration. A similar simulation structure is used to model a two-bladed WT with an induction generator. The model is utilized to study the impact of the aeroelastic phenomena tower shadow and yaw error on the power quality of wind power systems.

Due to the environmental and economical concerns, it is expected that a huge number of wind farms are going to be connected with the existing networks in the near future. However, the wind being intermittent sources of power, cannot meet the load demand all of the time. Wherever intermittent power sources reach high levels of grid penetration, energy storage becomes one option to provide reliable energy supplies. Therefore, this book deals with different approaches to stabilize a grid-connected wind farm.Among the various energy storage devices SMES is one of the options to provide reliable and fast response energy to the grid. These devices can help to make renewable energy more smooth and reliable, though the power output cannot be controlled by the grid operators. They can also balance micro grids to achieve a good match between generation and load demand. Also, it can significantly improve the load availability, a key requirement for any power system. The energy storage, therefore, is a desired feature to incorporate with renewable power systems, particularly in stand alone power plants. Thus this book investigates different methods to use SMES for stabilizing windfarm.

Bending Curvature: Design Research and Experime...

ggf. zzgl. Versand

Bending is a phenomenon that occurs with great frequency due to the presence of natural forces like gravity, wind. It occurs whenever an element is subjected to an external load applied perpendicularly to its longitudinal axis. Every known element, independently of its stiffness, exhibits certain amount of bending. This research explores this phenomenon not as a failure mode to provide tolerance for, but as a tool to design with. The design research presented here emerged from a combination of digital explorations and analogue experiments with bending rods. The aim was to create a model that would incorporate the interaction between bending rods, the transfer of forces and the repercussion on the geometry. Experimentation starts with understanding the behaviour of a single element in its simplex situation and simulating this behaviour in a computational environment. Complexity is increased when multiple rods are in play with bending in various planes as their curvature is negotiated with that of their neighbours and thus a process of self organization with multiple parameters is present until equilibrium was attained.

This paper focuses on calculating the most economically efficient ways of limiting CO2 emissions using technologies available in Europe. The emission scenarios incorporate nuclear power plants and mixes of coal power plants with on-shore wind farms, off-shore wind farms and hydroelectric power plants, all equal in terms of CO2 emission reduction within the set time horizon, with technology differences and natural resources accounting for different final calculated costs of electrical energy production. With little to no chances of Poland adapting both an ambitious renewable scheme and a nuclear scheme, a renewable/coal mix should be chosen, due to its higher economic efficiency. For questions, different time horizons, studies incorporating forestation (actually more profitable than carbon credits) or Life Cycle Assessments, please contact me at jhwisniewski@gmail.com
