Brief description of the drawings
Fig. 1 is a kind of generated energy acquisition data intelligence inspection based on the big-dipper satellite communication technology that the present invention proposesSurvey and processing method.
Detailed description of the invention
With reference to Fig. 1, a kind of generated energy acquisition data intelligence based on the big-dipper satellite communication technology that the present invention proposesDetect and processing method, comprise the following steps:
S1, setting and power plant generate electricity one to one threshold value and integration electric weight, generating threshold value is the unit intervalGenerated energy in length; Integration electric weight is that generator active power value is carried out the value after integration to the time.
The ammeter table code data collecting is held by S2, the power plant that receives in real time big-dipper satellite transmission.
In practical application, for the ease of the identification of power plant data, in electrical network, all there is corresponding volume in each power plantNumber. So, can building database, will generating threshold value and electrical network electric quantity data and power plant numbering binding after depositStorage, in database, is searched and is called so that follow-up.
S3, read the history value of the last ammeter table code data receiving in power plant of storage, and read generatingThe generating threshold value that factory is corresponding, compares current real-time table code value and history lists code value. Current real-time table codeThe comparative result of value and history lists code value is the foundation of subsequent treatment. Step S3 is specially: according to electric weight numberObtain the last electrical network electric weight receiving in power plant to be detected according to the power plant numbering in transmitting procedure from databaseThe history lists code value of data and corresponding generating threshold value, carry out current real-time table code value and history lists code valueRelatively. In this step, electrical network voltameter code data of every reception, all right by what store in itself and databaseThe electrical network voltameter code data that the nearest time memory in power plant of answering enters compares, to avoid due between the timeEvery the judged result unreliability causing too for a long time.
If the current real-time table code value of S4 is less than history lists code value, abandon current real-time table code value. Electrical networkElectric quantity data refers to that power plant is by the electric weight summation of sending on electrical network, so electrical network electric quantity data does not exist negative increasingLong phenomenon, if the current instantaneous value detecting is less than history value, illustrates that current instantaneous value is in transmitting procedureMiddle distortion, nonsensical.
If the current real-time table code value of S5 equals history lists code value, store current real-time table code value.
If the current real-time table code value of S6 is greater than history lists code value, calculate current instantaneous value and history valueInterval time, by the reasonable generated energy in the time interval and generating threshold calculations interval time, and calculate and work asThe difference of front instantaneous value and history value, then compares difference and reasonable generated energy. In this step,Interval can be length interval time of the time of reception of current instantaneous value and the time of reception of history value. ThisIn embodiment, for the accuracy that ensures that reasonable generated energy calculates, adopt current instantaneous value interval timeLength interval time of the acquisition time of acquisition time and history value. For accurate interval time, the step of obtainingThe electrical network electric quantity data receiving in real time in rapid S2 is all attached with its acquisition time.
If S7 difference is less than or equal to reasonable generated energy, store current real-time table code value.
If S8 difference is greater than reasonable generated energy, abandon current instantaneous value and also substitute with integration electric weight,Simultaneity factor is automatically carried out related log record and is carried out alarm.
S91, while satisfying condition S7, calculate the charge value in acquisition time interval, and calculate between acquisition timeEvery the electric weight difference of interior charge value and the integration charge value in this time interval, by electric weight difference with defaultPower threshold comparison. In present embodiment, the computing formula of integration electric weight is:
The integration charge value of W in formula (t) for calculating, the real-time active power value that p (t) is generator, TFor the time interval.
S92, electric weight difference are less than or equal to power threshold, judge that the charge value collecting is normal data,Charge value is carried out to data loading processing.
S93, electric weight difference are greater than electric weight threshold, carry out alarm, and notice electric flux system O&M personnel carry out peopleWork processing.
In present embodiment, by charge value and integration charge value are compared, when comparative result is rationallyIn scope, judge that these data are normal data, carry out data loading processing; When comparative result exceeds rationallyScope, carries out alarm, and by electric flux system O&M, personnel carry out artificial treatment. So, by rationally sending outElectric weight carries out secondary judgement by integration charge value to electrical network again after electrical network is once judged, is conducive toImprove the accuracy of electrical network Real-Time Monitoring.
Power plant is ever-increasing by the voltameter code value sending on electrical network, so as long as within interval time,There is electric weight online in power plant, and current actual table code value all should be greater than history value, still, and current actual table code valueIn transmitting procedure, also may occur that distortion becomes large situation, so need to enter one to current actual valueStep judgement.
Rationally generated energy is in interval time, and power plant is by the maximum possible value of the electric weight that send on electrical network. ToolWhen body is implemented, generating threshold value can be made as to power plant by the maximum rate of the electric weight that send on electrical network, i.e. unitIn time, power plant may be by the maximum charge value sending on electrical network, and the unit interval can be selected 1 second, so,Rationally generated energy can be generating threshold value and the product in the time interval.
In present embodiment, also comprise step S0: arrange and power plant electric weight float value one to one; StepIn rapid S6, rationally the computing formula of generated energy is: rationally generated energy=time interval × generating threshold value+electric weightFloat value. The setting of electric weight float value, is conducive to improve the accuracy that reasonable generated energy calculates, and avoids deletingUndistorted electrical network electric quantity data.
The above, be only preferably detailed description of the invention of the present invention, but not office of protection scope of the present inventionBe limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in, according to thisThe technical scheme of invention and inventive concept thereof are equal to replaces or changes, and all should be encompassed in protection of the present inventionWithin scope.
