Description
Technical field
The present invention relates to a kind of method of monitoring the supply voltage quality of resident.
Background technology
At present, mainly voltage monitoring instrument is relied on to the monitoring of resident's quality of voltage, and voltage monitoring instrument optionally can only be arranged on few places, be difficult to comprehensive covering, accurately cannot grasp the supply voltage quality of resident.Whether the supply voltage of each resident is qualified unknown.Although kilowatt meter reading-out system achieves remote meter reading at present, but local communication is adopted to the concentrator of full carrier networking, because of the restriction by carrier communication, be only limitted to freeze day to show code to the collection of electric energy meter information, accurately cannot grasp the supply voltage quality of each resident.
Summary of the invention
The object of the present invention is to provide the method for the supply voltage quality of a kind of comprehensive monitoring resident, administering for low-voltage provides guidance.
The method of the supply voltage quality of this monitoring resident provided by the invention, comprises the steps:
1). to day frozen acquisition: only adopt forward active energy indicating value, cancel the collection of oppositely meritorious and forward and reverse reactive energy indicating value;
2). to real-time data acquisition: the collection increasing voltage real time data, setting gathers frequency, carries out data acquisition by this collection frequency, and real time data timing is removed;
3). electric energy meter curve is formed: the data comprising timing point in the curve of electric energy meter;
4). curve markers: the data of timing acquiring are saved in history curve as this markers;
5). setting concentrator is to the retention time of voltage curve.
Described concentrator is no less than a week to voltage curve retention time.Step 2) the collection frequency that sets is some every day 7,11,15,19, real time data zero crossing is removed.Step 2) finding that certain block ammeter exists the magnitude of voltage lower than lower limit, gather frequency setting value and rise.The data of 7 points, 11 points, 15 points, 19 these four time points are comprised in electric energy meter curve described in step 3).Comprise the data of four time points in described curve, in the real time data that gather, be saved in history curve using 7 as markers at 7 o'clock to 11 o'clock; The real time data gathered to 15 after 11, is saved in history curve using 11 as markers; The real time data gathered to 19 after 15, is saved in history curve using 15 as markers; The real time data gathered to 23 after 19, is saved in history curve using 19 as markers.
The number of times gathered due to the voltage data of the inventive method to every block electric energy meter is very limited, again day frozen acquisition is cancelled to the collection of oppositely meritorious and forward and reverse reactive energy indicating value simultaneously, ammeter information acquisition platform can be gathered and freeze day to show code, the voltage of electric energy meter can be gathered again.Achieve the monitoring to all resident's quality of voltage, by the analysis software of main website, the ammeter of voltage out-of-limit can be retrieved, avoid the limitation that voltage monitoring instrument is layouted, can administer for low-voltage and guidance is provided.The present invention relies on the hardware of existing acquiring electric energy information system, without the need to increasing extras, only need modify to program part and carrying out remote upgrade.
Embodiment
Implementation condition: need the acquiring electric energy information system of relying on prior art, this system has all standing, the full feature gathered, and can carry out remote meter reading, this system is formed by main website, concentrator, electric energy meter networking.Concentrator carries out data acquisition by power carrier (PLC) to electric energy meter, is then kept in concentrator.Concentrator again timing passes to main website (or main website timing goes to copy the data of concentrator preservation) the data of these ammeters.
To inventive method be followed to the collection of electric energy meter data, carry out in accordance with the following steps:
1). to day frozen acquisition: only adopt forward active energy indicating value, cancel the collection of oppositely meritorious and forward and reverse reactive energy indicating value;
2). to real-time data acquisition: the collection increasing voltage real time data, every day timing acquiring several times, general every day in 7 points, 11 points, 15 points, 19 collection, one day totally four times, the removing of real time data zero crossing;
3) if. step 2) be the data gathering 7 o'clock, 11 o'clock, 15 o'clock, 19 o'clock every day, the data of these four time points should be comprised in the curve of electric energy meter;
4). the data of timing acquiring are saved in history curve as this markers.When platform district table is haggled over many, the successful time span of every block table data acquisition is very large, is unified curve markers, does following regulation:
7---11 real time datas gathered, are saved in history curve using 7 as markers;
11---15 real time datas gathered, are saved in history curve using 11 as markers;
15---19 real time datas gathered, are saved in history curve using 15 as markers;
19---23 real time datas gathered, are saved in history curve using 19 as markers;
5). the retention time of setting voltage curve is generally no less than a week;
6) if. finding that certain block ammeter exists lower than the magnitude of voltage of lower limit, will rise to the collection density of its voltage curve, within such as one day, gather 24 point data, every integral point collection is once.
The number of times gathered due to the voltage data of the inventive method to every block electric energy meter is very limited, again day frozen acquisition is cancelled to the collection of oppositely meritorious and forward and reverse reactive energy indicating value simultaneously, ammeter information acquisition platform can be gathered and freeze day to show code, the voltage of electric energy meter can be gathered again, that is original meter-reading function of this system can be kept, the supply voltage quality of resident can be monitored again, by the analysis software of main website, the ammeter of voltage out-of-limit can be retrieved, thus find low-voltage user.
In practical operation, only concentrator software need be revised, by the inventive method programming supplement in former control program.
Below the partial data that the Zhuzhou company resident in 28 days April in 2015 inquired in collection main website self-defined report shows representative point voltage, in table one.
Table one: platform district household representative point voltage acquisition form
Above-mentioned table one can find voltage out-of-limit user through simple sequence, as:
Wang Haiming: 11 point voltages are 173.2,19 point voltages is 166.5
Wang Xinyun: 11 point voltages are 185.2
Chen Shengdian: 11 point voltages are that 191.8 users such as these low-voltages such as grade are found very soon.
