Brief description of the drawings
Fig. 1 is a kind of detection of generated energy acquisition data intelligence and place based on Beidou satellite communication technology proposed by the present invention
Reason method.
Embodiment
Reference picture 1, a kind of generated energy acquisition data intelligence detection based on Beidou satellite communication technology proposed by the present invention
With processing method, comprise the following steps：
Generating threshold value and device electricity, generating threshold value are in unit time span correspondingly for S1, setting and power plant
Generated energy；Device electricity is the value after generator active power value integrates to the time.
The ammeter table code data that S2, the power plant end of real-time reception Beidou satellite transmission collect.
In practical application, for the ease of the identification of power plant data, there is corresponding numbering in each power plant in power network.Therefore
And database can be established, by generating threshold value and power grid electric data with being stored after power plant numbering binding into database, so as to
It is follow-up to search and call.
S3, the history value for reading the last ammeter table code data received in the power plant stored, and it is corresponding to read power plant
Generating threshold value, by current real-time table code value compared with history value.The comparative result of current real-time table code value and history value,
It is the foundation of subsequent treatment.Step S3 is specially：Power plant numbering in electric quantity data transmitting procedure obtains from database
The history value and corresponding generating threshold value of the last power grid electric data received in power plant to be detected, by current real-time table code
Value is compared with history value.In this step, power grid electric table code data are often received, all by it with being stored in database
The power grid electric table code data that the corresponding nearest time memory in power plant enters are compared, to avoid because time interval is led very much long
The judged result unreliability of cause.
If S4, current real-time table code value are less than history value, current real-time table code value is abandoned.Power grid electric data refer to
Power plant is by the electricity summation sent on power network, so negative growth phenomenon is not present in power grid electric data, if what is detected works as
Preceding real-time table code value is less than history value, then illustrates current real-time table code value distortion in transmitting procedure, nonsensical.
If S5, current real-time table code value are equal to history value, current real-time table code value is stored.
If S6, current real-time table code value are more than history value, when calculating the interval of current real-time table code value and history value
Between, passage time the interval and reasonable generated energy in generating threshold calculations interval time, and calculate current real-time table code value with going through
The difference of history value, then by difference compared with reasonable generated energy.In this step, interval time can be current real-time table code
The interval time lengths for receiving time and the reception time of history value of value.In present embodiment, in order to ensure reasonable generated energy
The accuracy of calculating, interval time use the interval time of the acquisition time of current real-time table code value and the acquisition time of history value
Length.In order to accurately obtain interval time, the power grid electric data of real-time reception are attached with its acquisition time in step S2.
If S7, difference are less than or equal to reasonable generated energy, current real-time table code value is stored.
If S8, difference are more than reasonable generated energy, abandon current real-time table code value and substituted with device electricity, together
When system carry out related log record automatically and alerted.
S91, when meeting condition S7, the charge value in acquisition time interval is calculated, and calculate the electricity in acquisition time interval
Value and the electricity difference of the device electricity value in the time interval, by electricity difference compared with default power threshold.This reality
Apply in mode, the calculation formula of device electricity is：
W (t) is the device electricity value calculated in formula, and p (t) is the real-time active power value of generator, and T is between the time
Every.
S92, electricity difference are less than or equal to power threshold, then the charge value that collects are judged as normal data, to electricity
Value carries out data loading processing.
S93, electricity difference are more than power threshold, then are alerted, and notice electric energy system operation maintenance personnel is manually located
Reason.
In present embodiment, by by charge value compared with device electricity value, when comparative result in the reasonable scope,
The data are then judged for normal data, carry out data loading processing；When comparative result exceeds zone of reasonableness, then alerted, by
Electric energy system operation maintenance personnel carries out artificial treatment.In this way, power network is carried out after once judging by reasonable generated energy, further through
Device electricity value carries out secondary judgement to power network, is advantageous to improve the accuracy that power network monitors in real time.
Power plant is ever-increasing by the voltameter code value sent on power network, as long as so within interval time, is generated electricity
There is electricity online in factory, and currently practical table code value all should be greater than history value, still, currently practical table code value in transmitting procedure,
The situation that distortion becomes big is likely to occur, so need to determine whether current actual value.
Reasonable generated energy is that power plant passes through the maximum value possible of the electricity sent on power network in interval time.Specific implementation
When, generating threshold value can be set to power plant by the maximum rate of the electricity sent on power network, i.e., power plant may in the unit interval
By the maximum charge value sent on power network, the unit interval may be selected 1 second, in this way, rationally generated energy can be generating threshold value and time
The product at interval.
In present embodiment, in addition to step S0：Set and the one-to-one electricity float value in power plant；In step S6,
Rationally the calculation formula of generated energy is：Reasonable generated energy=time interval × generating threshold value+electricity float value.Electricity float value
Set, be advantageous to improve the accuracy that reasonable generated energy calculates, avoid deleting undistorted power grid electric data.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
