Description
Technical field
The present invention relates to wind power plant (abbreviation wind power plant) intelligence control system fields, are based on energy more particularly to one kind
The wind power plant intelligence Yaw control method and its system of buret reason.
Background technique
Wind generating set yaw unties the mooring rope Traditional control field: since wind direction has fluctuation and randomness, when wind direction becomes
When change, cabin is needed, ceaselessly to wind, after cabin rotates to certain angle, the electricity in tower will to be caused according to wind vector
Cable torsion.Although this cable belongs to flexible cable, but also have ultimate torsional angle degree, so when reaching the limit of angle, just
It needs Wind turbines to yaw automatically to untie the mooring rope, serious electric power accident otherwise can occur.In traditional control system of wind turbines, reach
Cable reverse extreme angles when, unit must be shut down, then by control yaw module rotation cabin by flexible cable restore to
Originally straight state.However since nacelle weight is larger, yaw module is when executing cabin yaw instruction, it is impossible to speed mistake
Fastly, general rotation speed is 0.5 °/S, in superposition shutdown, opens the mechanical actions such as machine, one circle (360 °) about 12 of yaw that unties the mooring rope~
15min, if the unit frequent shutdown during strong wind in wind power plant unties the mooring rope, it will cause the loss of generated energy.
Wind power plant intelligence control system field: more next with the fast development of wind-powered electricity generation industry numerical and intelligent
More scientific research institutions begin one's study wind power plant field grade intelligence control system, for promoting the generated energy of whole field.But this
The reasons such as field is started late, and the resource of superposition scientific research institution investment is limited, cause research achievement less.It is transported in practical wind power plant
When battalion, multisystem, multi-platform cooperation are needed, but the data between these systems are not fully used, each system
Kernel control module data it is even more relatively independent, data are unable to timely sharing, though control effect can satisfy check requirements,
But do not accomplish the degree of intelligent fining, cause the avoidable loss generated energy of wind power plant sheet not obtain in time
Effectively retrieve.
Based on the above circumstances, the present invention mainly has studied wind power plant intelligence control system and power network dispatching system, wind power plant
In the case that wind power prediction system and control system of wind turbines realize data sharing, the visitors such as time scale, various dimensions are considered
Sight factor, the Wind turbines in intelligent control wind power plant yaw in advance to untie the mooring rope, and guarantees wind power plant each wind turbine before strong wind weather
The cable redundancy of group is sufficiently large, reduces since outage caused by strong wind yaws the generated energy for loss of untying the mooring rope.And this wind power plant intelligent control
System can be shut down the wasted power of unit, to the greatest extent may be used by the technologies such as the rated power that promotes Wind turbines in short term, dynamic compensation
It can be reduced the generated energy for untying the mooring rope and losing due to shutting down yaw, while effectively preventing, reducing the generation of cable fault.This hair
It is bright to be widely used in wind-powered electricity generation industry.
Summary of the invention

Major accident caused by effect.
As shown in Fig. 2, the present invention also provides a kind of wind power plant intelligence yaw control system based on energy management, including
Wind power plant intelligent control module, wind power plant wind power prediction module, dispatching of power netwoks module, Wind turbines are go the rounds data acquisition module
It is the wind power plant wind power prediction module, the running of wind generating set data acquisition module, described with Wind turbines control module
Dispatching of power netwoks module, the Wind turbines control module are electrically connected in the wind power plant intelligent control module.
Further, two Wind turbines control modules are no less than including, the Wind turbines control module and every
One Wind turbines is mating to be correspondingly arranged.
Dispatching of power netwoks module main task is to keep power generation balanced with load at any time, it is desirable that dispatches each portion of administration
Door is stringent to complete scheduler task.Dispatching of power netwoks module produces feelings according to the historical data of load variations, weather forecasting, analysis electricity consumption
Then condition and social life rule formulate electrical generation burden, operation meter to the following progress total system load prediction in 24 or 48 hours
It draws, wherein operational plan is exactly the load curve according to prediction, by economic load dispatching principle, to traditional fuel power supply, new energy electricity
Source is made rational planning for and is arranged, and each power plant electrical generation burden is distributed.
In this framework, generation schedule and the instruction of real-time peak regulation are handed down to wind power plant intelligent control mould by dispatching of power netwoks module
When block can be rationed the power supply with advance notice wind power plant, amplitude of rationing the power supply about how many equal key message.
Wind power plant intelligent control module main task is to receive, execute the instruction of dispatching of power netwoks module, coordinates wind-powered electricity generation in field
Unit carries out the control of active power and reactive power, the power target value that dynamic following dispatching of power netwoks issues.
In this framework, running of wind generating set data acquisition module obtains the generation schedule data of dispatching of power netwoks, wind in real time
The cable windup-degree of all Wind turbines in power prediction data and wind power plant, these comprehensive key messages, decision wind power plant
Electric system peak regulation is participated in when rationing the power supply, when which unit is carrying out yaw and untie the mooring rope, to guarantee unit cable before strong wind weather
Amount of redundancy is sufficiently large.
Wind power plant wind power prediction module, be according to the information-related data of wind farm meteorological, using physically simulated calculation and
Scientific statistics method carries out ultra-short term, short-term and in different time periods forecast to the wind direction and wind velocity of wind power plant, to predict outlet air
The following power of electric field, and these prediction data are transmitted to dispatching of power netwoks module and wind power plant intelligent control module, dispatching of power netwoks
Module combines numerous control targets such as these operational plans, feeds back to wind power plant intelligent control module dispatch command.In this framework
In, wind power plant intelligent control module is by prediction data, and when the small wind of decision or strong wind weather, when which unit is being carried out partially
Boat is untied the mooring rope.
Wind turbine control module is the comprehensive control system being made of a variety of components.Wind turbines yaw module
It is one of the chief component of control system of wind turbines.Since Wind turbines may be yawed constantly to a direction, machine
The cable of group overhang is possible to generate excessive kink and make cable fracture, failure, therefore, the most important work of yaw system
With being that can automatically terminate winding when cable reaches design winding value, cable is avoided to be broken and generate serious electric power accident.?
In this architecture design, the yaw that Wind turbines can receive wind power station control system untie the mooring rope instruction carry out shut down yaw untie the mooring rope.
The present invention proposes yaw intelligent control method and system based on wind power plant energy management, can be in advance to cable angle
It spends big unit to untie the mooring rope, it is ensured that unit cable angle redundancy is sufficiently large, avoids the power generation due to yawing loss of untying the mooring rope as far as possible
