IEC61850 standard-based data online monitoring method and system, terminal and medium

Abstract

The invention discloses an IEC61850 standard-based data online monitoring method, which comprises the following steps of: according to an IEC61850 standard, establishing an initial online monitoring model by taking an equipment type, a state monitoring type and a logic node of intelligent electronic equipment to be monitored as nodes; establishing a mapping relation corresponding to the unified state monitoring model to obtain a target online monitoring model, wherein the mapping relation comprises logic nodes of the online monitoring model, DOI nodes and remote units of the logic nodes respectively correspond to monitoring points of the unified state monitoring model and remote units associated with measurement and monitoring points; collecting monitoring data of the intelligent electronic equipment to be monitored, and matching the monitoring data with the logic nodes of the target online monitoring model to generate a corresponding data point file; and transmitting the data point file to a management information large area where the unified state monitoring model is located through cross-security-area transmission, and accessing the data point file periodically to the unified state monitoring model. The method provided by the invention meets the requirement of cross-regional data interaction, and is low in cost and easy to implement.

Description

technical field [0001] The invention relates to the field of power system information technology, in particular to an IEC61850-based data online monitoring method, system, terminal and medium. Background technique [0002] At present, according to the requirements of the safety protection specification for the secondary system of the power grid, the power grid company has established multiple protection measures such as security zones, private networks, dedicated isolation, and encryption authentication to address the data business needs of the upper and lower levels, network vertical and horizontal interconnection, and data communication issues. The mechanism has built the foundation of the power safety protection system. In order to meet the requirements of safety protection regulations, the power grid company proposes to place the on-line monitoring system of substation equipment and transmission line equipment in the non-control area of ​​the production control area, and...

Problems solved by technology

In order to achieve seamless integration with the online monitoring model, the existing technology is usually: the unified status monitoring model extends its original model from the perspective of remote data transmission, but due to the complex structure of cross-security data interaction deployment, this method It cannot meet the high concurrency and fast data transmission requirements of cross-safety zone data interaction; at the same time, each functional processing unit across security zones is deployed independently, and the coupling between them is poor, which will affect the transmission efficiency of data interaction, and once In case of equipment failure, it is difficult to troubleshoot, which further increases the difficulty and cost of later maintenance work
