Description
Technical field
The present invention relates to technical field of wind power generation. It is more particularly related to a kind of wind-driven generator.
Background technology
In recent years, from the view point of the protection of environment, the wind power generation plant of wind-force is utilized to attract attention. Wind power generation plant is generally of the rotor that multiple blades are installed on wheel hub. Rotor is equipped on cabin, and this cabin is located on the pylon erectting setting on land or ocean. In this wind-driven generator, blade receives wind and rotor rotates, rotor rotate to the electromotor transmission being accommodated in cabin, electromotor generates electric power.
The feature 1 of wind-power electricity generation) reproducible clear energy sources wind-power electricity generation is a kind of reproducible clear energy sources, does not consume fossil resource also free from environmental pollution, this is the advantage that heat power station is incomparable; 2) the Construction of Wind Power phase of construction period short ten MW class was less than 1 year; 3) installation scaleable can determine once to install scale according to fund state, has a Taiwan investment gold just can install an operation one; 4) reliability height is applied to wind power generating set modern high technology and makes its generating reliability be greatly improved, in, Large-scale Wind Turbines reliability brought up to 98% from the 50% of the eighties, higher than thermal power generation and unit durability up to 20 years; 5) cost low from the wind energy turbine set abroad built up, cost per kilowatt and per kilowatt time electricity price be below thermal power generation, compare with conventional energy resource generating there is competitiveness. China due to medium-and-large-sized wind power generating set all from external introduction, cost and electricity price compare thermal power generation height, but along with large medium size wind generator realizes production domesticization, industrialization, the cost of wind-power electricity generation and electricity price all will be less than thermal power generation in the near future; 6) automatization level of the simply modern medium-and-large-sized wind-driven generator of operation maintenance is significantly high, completely can when unattended duty normal operation, only need to be periodically subject to the maintenance of necessity, be absent from the overhaul problem of thermal power generation; 7) soil of Jin Zhan thermal power plant 1% such as building such as actual floor space small generation set and monitoring, power transformation etc., all the other places are still available for agriculture, herd, fishing uses; 8) generation mode variation wind-power electricity generation both can be incorporated into the power networks, complementary system can also be formed with other energy such as diesel generation, solar electrical energy generation, water generating unit, can also independent operating, therefore provide realistic feasibility for solving backwoodsman electrical problem;9) the little single wind generator pool-size that determines owing to wind energy concentration is low of single-machine capacity can not be very big, with present thermal power generation unit and nuclear power generating sets cannot compared with. Additionally wind regime is unstable, sometimes calm damaging strong wind again sometimes, and this is all the practical problem that wind-power electricity generation must solve.
At present, the automatic pitch-controlled system of Wind turbines substantially can be divided into three kinds, i.e. hydraulic variable propeller system, electric variable propeller system and centrifugal passive paddle changing system, wherein hydraulic variable propeller system is because of its easy oil leakage, controller is expensive, hydraulic oil temperature influence is big, need many defects such as periodic oil change and filter, existing market is rarely employed, electric variable propeller system has certain advantage compared with hydraulic variable propeller system, occupy staple market at present, but because its cost is too high, excessively complicated, components and parts are required extremely harsh, and pareira electricity, need frequent maintenance etc., so it neither perfect scheme, why occupying staple market is also wind-powered electricity generation industry caving-in bash, and centrifugal passive paddle changing system is because himself constructing reason, can be used only in middle-size and small-size wind turbine, and show not ideal.
