The conventional telecontrol data storage and processing method is to store directly according to the type of collected information. Although this method is simple to store, the telecontrol system needs to perform secondary processing or judgment on the data when using the data, such as single-point remote credit 0, 1 means, while 0 means both quantile and no data in the system, which is not conducive to the distinction of data characteristics

[0027] void DealYXByInclusion(CIED*pIED, CIEDLink*pLink, CRCB*pRCB, PRIM_DATA*prims, const int leaf_cnt, ST_UINT8*Inclusion, const int item_cnt, ST_UINT8*EntryID)
[0028] This function realizes the parsing report according to the Inclusion method. The function passes the IED model information of the 61850 device, device connection, report, data parameters, Inclusion and other parameters into the function, and searches for the position where the bit is 1 in the Inclusion according to the uploaded report, then its The position indicates which signal in the data set has displacement information, and the position information can be set to the IED model of the 61850 device.
[0031] This function implements report parsing according to the index path. The function passes the IED model information, device connection, report, and data parameters of the 61850 device into the function, and matches the index path in the report with the index path in the device model one by one. To find out the corresponding remote signaling point, the location information can be set to the IED model of the 61850 device.
[0032] 2. Design single-point and double-point conversion functions and their inverse functions to realize the conversion between double-point remote signaling and single-point remote signaling.
[0041] This function realizes the conversion between double-point remote signaling and single-point remote signaling.
[0042] 3. Design a data quality maintenance module, which is used to maintain the quality of collected and processed remote signaling and telemetry data.

Abstract
The invention relates to a data acquisition and processing method for a substation remote-action system. Acquired and processed data are analyzed and reported according to the combination of Inclusion and an index path. Analyzed telemetry data are is stored in a floating point format. Analyzed remote signalling data are stored in two-point remote signalling. Acquired and stored data are maintained by a separate function module. The data format is converted according to needs. The modification of a part of the quality is allowed. According to the invention, the forwarding accuracy of the telemetry data is ensured; the storage format of the data in the system is unified; the chaos of single-point and two-point co-storage of the remote signalling data is avoided; the data quality is maintained by the separate module; the forwarded data are processed according needs; and the compatibility and the remote-action performance of the system are improved.
Description
technical field [0001] The invention relates to a substation telecontrol system, in particular to a data collection and processing method for a substation telecontrol system. Background technique [0002] Substation telecontrol system, as an important branch of the State Grid power stationautomation system, plays a connecting role in the entire automation system. The basic function of the substation telecontrol system is to realize the collection, storage, processing and forwarding of data in the substation to the dispatching master station. Therefore, a good data collection and processing method can not only improve the data processing efficiency, but also reduce the system load and improve the reliability of the system. It can not only solve the application requirements of the current IEC61850 standard smart substation, but also be compatible with the data collection, processing and forwarding of the previous conventional substation. [0003] The current method of data a...
