Description
Technical field
The present invention relates to power prediction technical field, particularly a kind of side for improving numerical weather forecast downloading reliability
Method.
Background technology
Domestic at present is short-term（It is 0 ~ 72 hour following）The power prediction system mostly physical model based on numerical weather forecast
Prediction calculating is carried out, precision of prediction is influenced by numerical weather forecast precision.For specified wind field or photovoltaic plant, weather
Reporting services quotient periodically issues the primary weather prognosis data 3 to 7 days following daily, wherein the forecast precision first day following is most
Height, forecast precision several days subsequent can be declined.Power prediction system is daily periodically from the server of weather forecast service quotient
It is upper to obtain newest weather prognosis data, and the prediction of photovoltaic plant short term power or wind power plant short term power are calculated on this basis
Prediction result is sent to higher level traffic department, carries out the examination of precision of prediction so that power grid can by prediction data, daily timing
The operation of safety economy.
Weather forecast service quotient usually opens FTP service on the server of oneself, and power prediction system is downloaded by FTP
Mode obtain numerical weather forecast.Using single FTP downloading modes, it sometimes appear that weather prognosis data failed download
Failure, power prediction system can not obtain newest numerical weather forecast on time, can only choose the data downloaded before and be transported
Calculation is handled.This precision that will influence power prediction result.
Invention content
It is an object of the present invention to provide a kind of methods for improving numerical weather forecast downloading reliability, reduce Numerical Weather
The influence that failure brings short term power forecasting system is downloaded in forecast, so as to improve precision of prediction.
The technical solution that the present invention takes is specially：A kind of method for improving numerical weather forecast downloading reliability, power

FTP service, the data server of weather forecast service quotient are uploaded to numerical value day daily periodically by weather prognosis data by FTP
In gas forecast download server specified data storage file.This specified data storage file, that is, passive acquisition modes are corresponding
Data storage file.
Data transfer mode of the present invention includes public mailbox transfer mode：One public mailbox, weather forecast are set
The weather prognosis data of same day publication are sent to public mailbox by the timing daily of the server of service provider, and numerical weather forecast is downloaded
Server extracts newest weather prognosis data from public mailbox, preserves into corresponding data storage file.Above-mentioned public postal
Case can be apply on the internet, account and password in weather forecast service quotient server and numerical weather forecast download service
Disclosed any E-mail address between device.Numerical weather forecast download server daily download time can be set in weather forecast
After service provider's server data transmission timing time.
Preferably, weather prognosis data of the present invention are text file, and each data storage file is based on date setting number
According to file directory, the weather prognosis data obtained daily are stored in respectively under the data file content on corresponding corresponding date.It can be straight
The index using the date as data file content is connect to preserve the meteorological data obtained daily.Certainly other forms are alternatively
Data file, and text file is more convenient the direct application of power budget system.
In the present invention, power prediction system includes power prediction computing module；In step S3, power prediction computing module follows
Ring retrieves the corresponding data storage file of each data transfer mode successively, until retrieving the corresponding data of first current date
Weather prognosis data are not empty data storage file under file directory, then are corresponded to based on current date in the data storage file
Weather prognosis data under data file content carry out power prediction calculating.
Further, step S3 further include setting retrieval duration or retrieval cycle-index, when meet set retrieval duration or
When retrieving cycle-index, in the corresponding data storage file of all data transfer modes, the corresponding data file mesh of current date
Weather prognosis data under record are all empty, then the weather prognosis data for choosing the previous day in any data storage file carry out power
Prediction calculates.
Advantageous effect
Since the present invention employs between the data server of weather forecast service quotient and numerical weather forecast download server
A variety of independent data access and transmission mode so that when one of which access mode breaks down, its other party can be passed through
Formula obtains weather prognosis data.Solving the download failure of factor value weather forecast in the prior art leads to short term power prediction result
The problem of precision reduces, so as to ensure the reliability service of short term power forecasting system.
