Embodiment

[0033] Such as figure 1 As shown, a grid fault graphic analysis and display system based on model matching, the system includes: data acquisition module 1, data collection module 2, model matching analysis module 3 and graphic display module 4, specifically:

[0034] Data acquisition module 1: This module collects the state information in each electrical compartment of the substation. The state information includes the current and voltage electrical quantity information of the transformer secondary, the opening and closing position information of the circuit breaker and the isolation switch, and converts the state information into A transmission message, where the transmission message includes an SV, a GOOSE message or a proprietary protocol message.

[0035] Data collection module 2: This module performs data collection and synchronous processing on the transmission messages in each electrical compartment of the substation, and parses the synchronously processed transmission ...

Abstract

The invention relates to a model matching-based grid fault graph analysis and display system and method. The system comprises a data acquisition module, a data collection module, a model matching analysis module and a graph display module, wherein the data acquisition module is used for acquiring state information in each electric interval of a substation and converting the state information intoa transmission message; the data collection module is used for synchronously processing the transmission message in each electric interval and analyzing the transmission message into COMTRADE-based state information; the model matching analysis module is used for establishing a substation primary topology and a primary / secondary equipment correlation model, carrying out calculation on the COMTRADE-based state information to obtain a COMTRADE-based analog quantity and a COMTRADE-based switching value in each electric interval, and matching the COMTRADE-based analog quantity and the COMTRADE-based switching value with primary equipment; the graph display module is used for displaying a primary topological graph and an analog quantity and a switching value of the primary equipment in each electric interval, and carrying out visual display after grids break down. Compared with the prior art, the system and method are beneficial for intuitionally analyzing features of grid fault events andsatisfying the requirements for automatically analyzing grid faults.

Description

technical field [0001] The invention relates to a power grid fault display and analysis application technology, in particular to a model matching-based power grid fault graphic analysis and display system and method. Background technique [0002] The power system put into operation requires long-term stable work, but it covers a wide area and operates under harsh conditions. There are countless power generation, transmission, power consumption and other equipment in the system, and various faults will inevitably occur in various equipment during operation . In the fault analysis, the staff need detailed data to analyze the cause of the fault, so the parameter monitoring of the power system becomes an important work. [0003] With the continuous development of computer and communication technology, the application of fault recording devices in power grids has become more and more common. When the power grid fails or is disturbed, it is necessary to determine the nature of t...
