Description
Technical field
The utility model belongs to a kind of automated control technology, particularly relates to a kind of wind power generation automation control circuit.
Background technology
Wind energy, as a kind of clean regenerative resource, is more and more subject to the attention of countries in the world.The first half of the year in 1979, the U.S., on the Blue Mountains mountain of the North Carolina state, has built up again the windmill of a maximum in the world generating.Wind energy, as a kind of clean regenerative resource, is more and more subject to the attention of countries in the world.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 × 109MW, and wherein available wind energy is 2 × 107MW, than the water energy total amount that the earth can develop also large 10 times.Wind is utilized by people very early--mainly to be drawn water by windmill, flour milling etc., and now, people are interested is how to utilize wind to generate electricity.Utilize the trial of wind power generation, just start as far back as the beginning of this century.The '30s, Denmark, Sweden, the Soviet Union and the U.S. apply the rotor technology of aircraft industry, successfully have developed some small wind-driven generators.This small-sized wind power generator, extensively use on windy island and remote rural area, the power cost that it obtains is more much lower than the cost of electricity-generating of compact internal combustion engine.But, energy output is at that time lower, mostly below 5 kilowatts.Wind turbine generator, can divide wind wheel (comprising tail vane), generator and steel tower three part substantially.(larger wind power plants there is no tail vane, generally only has small-sized (comprising domestic type) just can have tail vane).
Utility model content
The purpose of this utility model is to solve the problem, and proposes a kind of wind power generation automatic control system, the feature that this wind power generation automatic control system has design science, rational in infrastructure, renewable, pollution-free, energy is large, prospect is wide.
The purpose of this utility model is achieved through the following technical solutions: wind power generation automatic control system, it is characterized in that: be provided with generator, double bond frequency converter, master control system, become slurry control system, described generator passes through double bond frequency converter and box type transformer at rotor output, Medium Voltage Switchgear, grid power transmission connects, described master control system is by data cable and double bond frequency converter, become slurry control system, Medium Voltage Switchgear control connection, rotor-side converter is provided with in described double bond frequency converter, net side converter, filter, soft initiator, fuse, contactor, circuit breaker, overvoltage crowbar, described generator passes through the contactor in double bond frequency converter at rotor output, circuit breaker, box type transformer, Medium Voltage Switchgear is connected with grid power transmission, described fuse passes through soft initiator, filter, net side converter, the rotor-end of rotor-side converter and generator forms control circuit.
Further, the described slurry control system that becomes adopts change oar drive motors to be realized the adjustment of blade angle by the rotation of gear drive gear ring.
Blower fan of the present utility model is applicable to this project wind energy turbine set and uses, and energy output is higher than other similar blower fan, and economic benefit is obvious; There is extremely strong low voltage ride-through capability; Due to the minimizing of drivetrain components, improve reliability and the availability of wind-driven generator unit; The minimizing of mechanical transmission component reduces the noise of wind turbine generator; The raising of reliability reduces the operation expense of wind turbine generator; Owing to decreasing number of components, greatly shortened the production cycle of complete machine; Adopt total power frequency conversion, online power quality is excellent; Converter plant adopts the mature technology through checking, and harmonic component is low; Engine room structure design have employed human oriented design scheme, facilitates operations staff's maintenance and inspection as much as possible, adds the servomechanism that climbs in the design, become especially light when operations staff is scaled a ladder in maintenance process; Unit has good wind field environmental suitability, is applicable to long-term sand and dust, low-temperature working environment; Unit is equipped with automatic lubricating system, for the bearing, gear ring etc. of unit provide lasting lubrication, reduces manual maintenance amount, and meanwhile, the lubricant grease avoiding each drive disk assembly can not get supplementing and enhance faster wear for a long time; Bidder's direct-driving type wind power generation unit operation is reliable and stable.Take into account meteorological for scene with environmental condition, 20 years overall design life-spans.
