Vertical axis wind turbine tip-speed ratio is low, and aerodynamic noise is low at various speeds, even reaches quiet effect under the slow-speed of revolution, is applicable to be arranged on to the high residential belt of noise requirements and the intensive region of population activity.
The basic principle of fan design:
When designing wind-driven generator, the parameter of employing, by directly having influence on the utilization ratio of wind-driven generator, enterprise's manufacture cost and customer using cost, also directly affects the developing in wind-driven generator market and captures.The basic principle of wind generator design is as follows:
(1), important spare part design principle is that the inefficacy of single part can not cause whole device to destroy;
(2), all important component can bear whole foreseeable various load;
(3), in equipment inspection and maintenance time interval, wind generating unit there will not be serious deterioration, considers the feasibility checked related components;
(4), every not measurable component in blower fan, should ensure that these component have enough durability at whole life period.
The external condition of wind generator design: under normal circumstances, when wind generator design, should consider the impact on wind-driven generator such as the external condition of built wind field, wind regime.
Wind-driven generator is subject to the restriction of environment (wind regime and other environment) and electric (electrical network) condition, may affect the load of blower fan, durability and operation conditions.For ensureing suitable safety and reliability level, in design, environment, electric parameter should be considered.
External condition can be divided into again normal and extreme two kinds of conditions, normal external condition is general relevant with operating conditions with long term structural load, and extreme external condition represents rareness but may be very crucial outside design condition, the design load situation of blower fan is combined by these external conditions and wind-driven generator operating mode.
Wind-driven generator class requirement: in the design, needs the external condition considered to depend on the expectation place that wind-driven generator is installed and venue type.The grade wind speed of wind-driven generator and turbulivity define.It is the environmental conditions standing average extreme wind speeds in the 10min of hub height chance upper 50 year one with reference to wind speed.Mean wind velocity is the assembly average of wind speed momentary value, generally refers to the wind speed mean annual value within many years.20 years working life of wind generator design.
Other environmetal impact: climatic factor can affect overall performance and the Security of wind-driven generator, should consider following environmental conditions when designing: the factors such as normal and extreme temperature range, humidity, air density, solar irradiation and rain, hail, snow, icing, thunder and lightning and salt fog.
The impact of load aspect: following kind of load should be considered during wind generator design: (1) inertial force and gravitational load, it is produced by effects such as vibration, rotation, gravity; (2) aerodynamic load, it is the various Static and dynamic load being interacted by fixing on air flowing and wind-driven generator and motion component and produced.(3) performance load, it is produced by the operation and control of wind-driven generator, comprises the starting of blower fan and the mechanical braking of stopping and transient load etc.(4) other load, as wake flow load, impulsive load, icing load etc.
