The technical scheme that realizes above-mentioned purpose is: a kind of collecting method that is used for the quality of power supply; This method be from based on image data the database of PQView and with this data importing in a quality of power supply intelligent information system; The event data and the steady state data that should comprise the table storage that branch is different based on the database of PQView wherein, adopt various tasks to import event data and steady state data; Each data that import a day; Event data concluding time and steady state data concluding time keep one to two day delay in the time of importing data and the table, and the mode of importing comprises automated manner and manual mode, wherein:
Described automated manner adopts the form of windows service, and service is carried out data acquisition and calculating according to configuration file automatically;
When gathering, having only the part monitoring point that data are arranged, the data of a part of check point are to join afterwards based in the database of PQView, at this moment, adopt manual mode to gather this part data again, and repeat computational data;
When using manual mode to carry out data acquisition and calculate, the date of system prompt source data and calculated date, the from date that user's input is recomputated, Close Date, and select to participate in again the monitoring point of calculating.
The above-mentioned collecting method that is used for the quality of power supply, wherein, in the described automated manner, the content of institute's configuration file comprises two parts, wherein:
The time range that database IP address, database-name, the service of part definition quality of power supply intelligent information system starts, the collection period and the double counting fate of harmonic data;
Another part configuration information is to based on the table of the database of PQView, confirm the table under the image data through the configuration of this part information, and the content that defines comprises the database table that will import.
The above-mentioned collecting method that is used for the quality of power supply wherein, when using manual mode to carry out data acquisition and calculate, when selecting to participate in the monitoring point of calculating again, can be selected several monitoring points simultaneously.
The invention has the beneficial effects as follows: the present invention periodically will be based on the data importing in the database of PQView in a quality of power supply intelligent information system; Through automatically and the mode that manually combines collected this based on the data in the database of PQView, for people provide the scientific decision foundation to the improvement of the quality of power supply.
Embodiment
To be described further the present invention below.
A kind of collecting method that is used for the quality of power supply; This method be from based on image data the database of PQView and with this data importing in a quality of power supply intelligent information system; The event data and the steady state data that should comprise the table storage that branch is different based on the database of PQView; The present invention adopts various tasks to import event data and steady state data, imports one day data at every turn, and event data concluding time and steady state data concluding time keep one to two day delay in the time of importing data and the table; The mode that imports comprises automated manner and manual mode, wherein:
Automated manner adopts the form of windows service; Service is carried out data acquisition and calculating according to configuration file automatically; In the automated manner; The content of institute's configuration file comprises two parts, wherein: the time range that database I P address, database-name, the service of part definition quality of power supply intelligent information system starts, the collection period and the double counting fate of harmonic data; Another part configuration information is to based on the table of the database of PQView, confirm the table under the image data through the configuration of this part information, and the content that defines comprises the database table that will import;
Automatically gathering with calculating is according to gathering based on the time in the database of PQView; The content time of gathering moves after gradually; When gathering, having only the part monitoring point that data are arranged, the data of a part of check point are to join afterwards based in the database of PQView, at this moment; Adopt manual mode to gather this part data again, and repeat computational data;
