Specifically, the detection of PQDIF data formats is primarily directed to the channel labels in PQDIF files, sequence label and sequence
Train value is detected, therefore the data source record firstly the need of parsing PQDIF files and observation note are detected to PQDIF files
Record.
As an example, the parsing of PQDIF files is realized on .NET platforms, by using by Electrotek
Class and function in the pqdcom4.dll dynamic link libraries of Concepts companies exploitation complete the parsing work of PQDIF files.
Pqdcom4.dll is freely downloaded on IEEE websites, pqdcom4.dll is added in project and shown by " addition is quoted "
For PQDCOM4Lib.The parsing of PQDIF files needs the relation ability between data source record and observational record in dependency logic structure
It can complete, so mainly parsing data source record and observational record, analysis program is mainly by using in PQDCOM4Lib
What the function in PQDCOM4Class classes was realized.But those skilled in that art understand that the invention is not limited in this compiling is flat
Platform, or this compiling function.
The analytic method flow of data source record is as shown in Figure 1.It comprises the following steps：
Step 1：The passage that data source is recorded, which is first obtained, when parsing data source record defines number.
Step 2：If channel number is not 0, call function parses each passage successively, is parsing the process of each passage
In, if important leaf node, then be assigned to variable storage according to step 3；If not leaf node then calls accordingly
Function further parses.
Step 3：According to the obtained channel information leaf node value of parsing, by the tagPhaseID in data source record,
TagQuantityMeasuredID, tagQuantityCharacteristicID field information are stored in tableChannels tables
In (channel definition table) and return, for being used during sense channel.
IEEE P1159.3 standards are determined corresponding to each logical channel by three kinds of label (as shown in table 1) combinations of definitions
Power quality index type.Three indexs are the first three items index in accompanying drawing 3.

| tagQuantityTypeID | ID_QT_VALUELOG |
| tagQuantityMeasuredID | ID_QM_VOLTAGE |
If each channel labels value of the correspondence illustrated in table 1 is respectively ID_PHASE_AN, ID_QT_VALUELOG and ID_
QM_VOLTAGE, you can it is stable state A phase voltage virtual values to determine this passage.
Step 4：According to the obtained sequence value information leaf node value of parsing, by tagValueTypeID (sequential value identifies,
Such as maximum, minimum value, average value), tagQuantityUnitsID (measured value unit),
TagQuantityCharacteristicID characteristic quantities (such as instantaneous, spike, virtual value) field information deposit record tables
In (sequential value table) and return, used when being detected for sequential value.
The channel labels and sequence label parsing observation note that can be obtained after data source record is parsed according to parsing
Record, Fig. 2 are the method flow diagram parsed to observational record.
As shown in Figure 10, electric energy quality monitoring data detection method of the invention includes channel labels detection, sequence signature
One or more in detection and sequential value error detection, it is example that the order in figure, which performs relation, does not represent step
Successively, the restriction whetheing there is, but can only perform it is therein one or more, detection execution sequence can also change.
Channel labels detection can be divided into the detection of channel labels missing, the unnecessary label detection of passage and the inspection of channel labels mistake
Survey.
Whether channel labels missing detection mainly detection PQDIF files, which have, lacks defined in standard channel definition table
Standard channel label, the relevant information of the standard channel label of missing is provided if having.
Fig. 4 is the flow chart of channel labels missing detection.It comprises the following steps：
Step 1：Read PQDIF files.
Step 2：Data source record to PQDIF files parses, and successfully resolved and data source record are not sky, then turn
Enter step 3.
Step 3：The channel labels in parsing data source record are obtained, are recorded as channel definition table tableChannels.
Step 4：The standard channel definition table tblChannelStandard to prestore is obtained from database.
Explanation：The detection of PQDIF data formats is needed first to select the PQDIF standard criterions of reference, from the foregoing, it can be understood that due to
The definition of IEEE P1159.3 standards is more early, has been difficult to fully meet demand of the grid company to power quality analysis, therefore often
IEEE P1159.3 standard criterions can be expanded, so in order to adapt to the demand of each grid company, the reference of PQDIF detections institute
Standard criterion can be selected by configuration file.The standard criterion of PQDIF detections institute reference can be stored in xml document,
Each field definition information of one embodiment Plays channel definition table is as shown in Figure 3.
Step 5：TableChannels tables are traveled through, are compared with channel labels in tblChannelStandard tables, such as
Channel labels in fruit tableChannels tables are present in tblChannelStandard tables, then exist
The standard channel label record of comparison is removed in tblChannelStandard tables；If it does not exist, then continue to travel through, until
TableChannels ends of list (EOL).
Step 6：Remaining standard channel label record is PQDIF missing documents in tblChannelStanderd tables
Channel labels, generation form return to user.
Fig. 5 is the unnecessary label overhaul flow chart of passage.It comprises the following steps：
Step 1：Read PQDIF files.
Step 2：Data source record to PQDIF files parses, and successfully resolved and data source record are not sky, then turn
Enter step 3.
Step 3：The channel labels after parsing data source record are obtained, are recorded as channel definition table tableChannels.
Step 4：Standard channel definition table tblChannelStandard is obtained from xml document.
Step 5：TblChannelStandard tables are traveled through, are compared with channel labels in tableChannels tables.If
The channel labels of comparison meet the label of channel definition table, and the channel labels are removed from tableChannels tables；It is if last
There is remaining record in tableChannels tables, then the remaining record in tableChannels tables is that the PQDIF files are unnecessary
Channel labels.
Step 6：Remaining channel label generation form in tableChannels tables is returned into user.
Fig. 6 is channel errors label overhaul flow chart, the detection of channel errors label and the execution of above two detection method
Step is similar.
Unlike, channel labels mistake refers to that the channel labels in PQDIF files neither completely include standard definition
Channel labels defined in table also have unnecessary channel labels, and the flow of channel labels error detection detects with unnecessary channel labels
Similar, difference is that two tables have residue after the completion of tableChannels tables and tableChannelStandard tables compare
Record, the remaining record in tableChannels tables is particularly likely that the channel labels of mistake, now by tableChannels
The remaining record in remaining record and tableChannelStandard tables in table is listed, and generation form returns to user.
In addition, for the channel labels of mistake, can be with the similar standard channel mark in standard of comparison channel definition table
Label, the result as channel labels error detection return.
Sequence signature detection is primarily directed to the sequence label missing detection under passage and sequence unit error detection.Sequence
Tag misses detect the standard sequence label firstly the need of the Acquisition channel from standard channel definition table, then by parsing PQDIF
The data source record of file obtains the sequence label of respective channel, and the two is compared to the sequence mark for determining whether missing
Label.The flow of sequence unit error detection is substantially similar with the detection of channel sequence tag misses, the difference is that sequence unit mistake
Detection be judge respective channel correspond to sequence unit it is whether wrong.

Step 5：Record tables are traveled through, is compared with recordStandard tables, judges the sequence label in record
Whether not exclusively include in recordStandard.
If the sequence label in record tables is present in recordStandard tables, in recordStandard tables
Remove corresponding standard sequence label；If it does not exist, then continue to travel through, until record ends of list (EOL).recordStandard
Remaining standard sequence label is the sequence label lacked in record tables in table.
Step 6：Record generation form in recordStandard tables is returned into user.

Step 5：Record tables are traveled through, is compared with recordStandard tables, judges the sequence unit in record
It is whether wrong.
Step 6：Provide the exact unit of sequence under respective channel.
Step 7：Generation form returns to user.
Sequential value error detection is to do quick detection, sequential value mistake to the sample sequence in PQDIF file observational records
Detect firstly the need of the sequential value average by parsing each sequence in data source record and observational record acquisition respective channel, then from
The upper lower limit value of sequential value under respective channel is obtained in standard scale, the last equal value sequence of ergodic sequence value, obtains sequential value average
Number not in the range of upper lower limit value, if the ratio of sample sequence exceeds standard model shared by number beyond upper lower limit value scope
Enclose, then it is assumed that the sequential value mistake of the sampling, it is on the contrary then correct.
