Embodiment Construction
[0022] The technical solution of the present invention will be described in further detail below in combination with specific examples according to the drawings in the description.
[0023] figure 1 Shown is the association relationship of the relevant data tables used in the implementation method of the data identification of the present invention. Obtain in-station equipment information and mutual connection relationships from the equipment library, and analyze the out-station topology structure through the real-time status of each switch and switch. According to the measurement relationship of the equipment, the telemetry and telesignalling data related to each equipment are obtained, and the bad data is identified through the mutual comparison of the quantity measurement. The specific implementation steps are as follows:

The invention provides a data identification realization method based on an SSD model. The method specifically comprises the following steps: (1), realizing a topology analysis of the real-time online state of a primary device of a transformer station by use of the primary device, a connecting point of the primary device, a connection relation of the primary device and measuring point information in an LN node which are defined in the SSD model; (2), performing data initialization to obtain a component related to a detection device for measurement, and performing completeness checking on the model in the station; (3), performing the topology analysis on the real-time online state of the primary device in the whole station; (4), based on the real-time topology analysis in the station, performing data rationality and failure detection on main transformer-correlated data and switch knife positions; and (5), performing failure data detection and alarming, i.e., marking a measuring quality position with a suspicious state to be suspicious and giving an alarm, and marking a measuring quality position with recovery of a suspicious state to be normal and prompting the recovery of the suspicious state.
Description
technical field [0001] The invention belongs to the technical field of power system substation automation, and in particular relates to a method for realizing data identification based on an SSD model. Background technique [0002] As the degree of automation of the power grid becomes higher and higher, the operation of the power system relies more and more on data. Accurate measurement data is the premise and condition for the safe and stable operation of the power system. However, due to reasons such as unreasonable layout, poor channel transmission, or lax management and operation of the real-time measurement system, the accuracy of data collected at the station end is reduced, and bad data must be detected and identified for real-time measurement data. The detection and identification of bad data based on real-time topology analysis in the station is one of the important functions of power system state estimation. Safe and stable operation is of great significance. Co...
