variable pitch control
Research on the Intelligent Controller Design Method of the Vertical Wind Turbine
In the twenty-first century, the environmental pollution and depletion of fossil energy have become major problems of threating to human’s progress and development. Therefore, people pay attention to discover and develop sustainable use of new energy more and more. The use of wind energy which are distributed widely, reserved largely, cheap and non-polluting is received [...]
Research and Design of CSCF Wind Power Generation Variable Pitch System
In our country, power supply of some remote area is difficult or more complex and power failure often occurs. In a situation of power failure, to ensure successful boating oars of wind generating set must have a good variable pitch system. In a situation of normal electricity supply in the system, the control of blades [...]
Research on the Variable-pitch Control System and Servo Unit for Wind Turbine
With the worldwide extent of industrialization and urbanization, energy and environmental issues has become the exigent problem for human survival and development. Wind energy, as one of the renewable energy, is becoming the most promising energy. On one side, because wind energy has characteristics of low density, randomness and instability, the output power of the [...]
Research on Intelligent Sliding Mode Variable Structure Control of Variable Speed Wind Turbine
Because of the decrease and pollution of traditional nature resource of energy, the exploitation of new energy appears more emergent. Wind power is provided with cleanness, pollution-free and sustainable use, so it gets more and more attention. Wind power generation is the main form of use of wind, it plays an important role in changing [...]
Study on Fuzzy Control for Variable-Speed Variable Pitch Doubly-Fed Wind Turbine
Human economic and social development are inseparable from energy supply. Reserves of conventional energy is not only limited, but large-scale use can also cause environment pollution. In order to solve the problem of contradiction between population and environment, we should establish new energy strategy and develop recycling economy. As an inexhaustible and renewable energy, wind [...]
Research on Constant Speed Control Method of Two-leaf Semi-rotary Structural VAWT
Energy and the environment have become the pressing issues to be solved which threaten human survival and development. Conventional fossil energy is extremely limited and it pollutes our living environment. Therefore, the development and utilization of renewable resources has attracted great attention around the world. Wind is from solar energy and its security, low-cost and [...]
Research and Development on Real-time Simulation Control System of VSCF Wind Power Generation
Because of continually normal energy sources diminishing and seriously environment pollution,it is paid more and more attention to by governments all around the world as its renewable and clean characteristic. Due to a lot of requirements, such as high dependability of electricity system, build up a simulation model for wind turbine power generator system is [...]
Active Power Smoothing Control of Wind Generation System
Wind power is a clean and renewable energy. The fluctuations of wind power often occur as the stochastic feature of wind speed. With the increase of the wind power capacity in power grid, the change of power and frequency in power system will exceed the limit range when the fluctuation of the wind speed is [...]
