Abstract
The invention relates to a wind power mass data communication method based on a network, comprising the following steps: classifying the data from the angle of the data transmission in a wind power station into second-level data and minute-level data; transmitting and monitoring the second-level data in real time by adopting the change of the commonly used networking protocol; and transmitting the data document formed by the minute-level data through a network manner at regular time; and defining a document named method of the minute-level document as a format of type-address -time. dat, thus the profile of the carried information can visually reflected. The method of the invention is used for defining a document format, thus being capable of transmitting the mass data, and automatically expanding the mass data. The method of the invention can satisfy the requirements of data types, time frequency and instantaneity and the like of the wind power information transmission, and automatically adapt to satisfy the requirement of the mass transmission.
Description
Technical field
The invention belongs to power system communication, relate in particular to a kind of based on network wind-powered electricity generation mass data means of communication.
Background technology
Along with the development of electric power system new forms of energy, the mode of power scheduling also changes taking place.For wind-powered electricity generation, the data such as meritorious, idle, electric current that only insert similar conventional power generation usage factory can not satisfy the requirement of lexical analysis, system need insert more comprehensively information of wind-powered electricity generation, comprise separate unit blower fan information, anemometer tower information, booster stations information, also will comprise calibration curve informations such as wind power prediction.The data type of these information, time frequency, real-time require to have nothing in common with each other; Simultaneously, because the blower fan quantity of each wind energy turbine set does not wait from hundreds of to thousands of, every typhoon machine need be gathered meritorious, idle, operating state equivalent, and therefore for system, data volume is a magnanimity, constantly increases along with the construction of wind energy turbine set.
For the collection of wind-powered electricity generation information, also do not have a kind of method preferably above-mentioned all types of data can be put into different categories at present and adapt to the transmission requirement of wind-powered electricity generation data, and the wind-powered electricity generation mass data is inserted the scale that adapts to wind energy turbine set.
Summary of the invention
Goal of the invention of the present invention is:
1, solves the transmission of wind-powered electricity generation different types of data.
2, solve the wind-powered electricity generation mass data transfers, and can adapt to the scale of wind energy turbine set automatically.
To achieve the above object of the invention, the present invention realizes by the following technical solutions:
(1) the wind energy turbine set data is classified according to transmission of angle,, require to classify, be divided into second a level and minute level data with reference to application function from real-time;
(2) the conventional according to this network stipulations transmission of using of second progression is as the IEC104 stipulations;
(3) minute level data form data file, regularly transmit by network mode;
(4) magnanimity blower fan data are minute level data, the title of defined file and form, and can expand automatically.
In the present invention, disclosed a kind of method of data being classified from transmission of angle.Wind-powered electricity generation information is divided into second level data and minute level data from the real-time angle with data, adopts different communication modes; The requirement of comparable data type is defined as single-point information and calibration curve information the file of different-format.
Second level data comprise: booster stations information, be mainly the information of wind energy turbine set point of presence, need to change transmit, monitoring in real time; Typical case's blower fan information.Adopt the IEC104 stipulations second when progression is reportedly defeated.
Through classification, minute level data are transmitted according to the mode of file, and minute level data kind is from the one point data to the curve data, and the time interval is not waited from 5 minutes by 1 day.
Minute level data comprise: the state of all blower fans, meritorious, idle; Mean wind speed, the wind direction of the differing heights that anemometer tower is set, temperature, air pressure; The ultrashort phase prediction curve of wind energy turbine set power; Next day wind power prediction curve etc.
For example, minute level data transmittal and routing form can be per state that transmitted all blower fans in 5 minutes, meritorious, idle; Mean wind speed, the wind direction of 3 height of per 5 minutes transmission anemometer towers, temperature, air pressure; The per 15 minutes ultrashort phase prediction curves of transmission wind energy turbine set power; Transmit wind power prediction curve next day every day.Minute progression adopts file mode when reportedly defeated, passes through Network Transmission.
The method of a kind of file designation and formal definition is provided in the present invention.The file designation form is: type _ address _ time .dat, time fills in by this type time granularity type, as: anemometer tower _ bridge east first wind energy turbine set _ 201010180015.dat is the anemometer tower data that bridge east first wind energy turbine set was issued 0: 15 on the 18th October in 2010, and title can reflect the overview of the information of taking intuitively.The attribute that the first row definition of data need transmit since the attribute of second row according to first row, is inserted the property value of concrete each data object, and along with the increase of anemometer tower quantity, the number of data object can expand downwards always, need not to define once more.File with reference to this method definition can transmit mass data, and can expand automatically.
The beneficial effect that the present invention reached: the invention solves the problem of wind-powered electricity generation data polymorphic type, magnanimity transmission, and method is simple and effective, easy to implement, has satisfied the demand of lexical analysis.
