Embodiment 1

[0097] A relay protection information modeling method based on secondary big data platform:

[0098] Step 1. Obtain all plant-equipment-signal information from the big data platform. All plant stations are recorded as sta1, sta2...staN, all devices are recorded as dev1, dev2...devN, and all signals are recorded as sig1, sig2 ...sigN.

[0099] Step 2. Correlate all the acquired plant, equipment and signal information locally, and form a complete hierarchical structure locally, such as figure 1 shown.

[0100] Step 3: Classify all signal points according to their names of alarm levels and signal types. For individual signals that fail to complete the typical classification, operators are allowed to manually specify or input information.

[0101] Step 4: Acquire all signal data and wave recording files in real time, and display them according to the pre-modeling. It also supports providing data sources for various advanced functions, and prompting relevant personnel through i...

Embodiment 2

[0193] like Figure 4 As shown, the modeling method includes a configuration data module, a model association tool, a real-time data communication module, and a data processing module on the local platform.

[0194] The layout of the actual site is shown in the figure. The local platform is connected to the big data platform, and the big data platform is connected to systems such as credit guarantee, wave recording, and secondary monitoring, collecting a large amount of information and data of secondary equipment. However, its content is disordered and chaotic to the outside world, and it is difficult to directly apply to fault analysis and processing. Therefore, the present invention is also suitable for processing the data corresponding to no model in the communication of other platforms.

[0195] Through the communication with the external big data platform and its own data processing, the present invention can first obtain a large amount of power grid operation data and s...

Abstract

The invention provides a relay protection information modeling method and system based on a secondary big data platform, and the method comprises the following steps: S01, endowing a plurality of stations in a region with physical IDs, obtaining all stations, equipment and signal information in the region from the big data platform, recording all stations as sta1, sta2,..., staN, recording all equipment as dev1, dev2,..., devN, and recording all signals as sig1, sig2,..., sigN; s02, associating all the acquired plant station, equipment and signal information locally, and forming a complete hierarchical structure on a local platform; s03, classifying alarm levels and signal categories of all signal point locations according to names; s04, all signal data and recording files in the big data platform are acquired in real time, and warning and classification are performed according to preset warning levels and signal classification; and S05, sorting the fault information in the fault time period.

Description

technical field [0001] The invention relates to the technical field of power grid relay protection, in particular to a relay protection information modeling method and system based on a secondary equipment big data platform. Background technique [0002] With the rapid development of my country's economy, the scale of my country's power grid is also expanding. In terms of monitoring, operation and maintenance of secondary equipment for relay protection, the types and numbers of various data platforms are increasing. Among them, the modeling of most substations is based on SCD. Each platform can rely on the signal points defined in the SCD model file for data transmission and model correspondence. [0003] However, in the actual application process, it is necessary to ensure that the models of the receiver and the sender are consistent during the data transmission process. For this reason, it is necessary to introduce the SCD version of the management and control platform, ...
