Reduction and generation method of action report of protection device at scheduling port

Abstract

The invention provides a reduction and generation method of an action report of a relay protection device at a scheduling port, which is applied to a power network relay protection and failure information management system. The method comprises the following steps: normalizing output information of a relay protection device on a station port, and sending the information by classification; establishing a communication specification between a master station and a slave station to guarantee integral data transmission; and outputting corresponding action report at the scheduling port of the master station according to the device type to realize reduction and generation of the device report at the scheduling port. The method in the invention helps realize that the action report is basically consistent with the report form and the content printed on the spot by the relay protection device in an information display layer of a master station system. The method is completed and practical; and the method helps perfect the information content sent by the relay protection device, solve the long-standing functional problems of the domestic relay protection and failure information management system such as scattered information, shortage of the content and the like, meanwhile formally realize long pass of the relay protection action report, is beneficial to relay protection professional staffs to carry out protection action analysis, and improve the integral practicability level of the system.

Description

technical field [0001] The invention is applied in the field of electric power automation of electric power system, and particularly relates to the direction of power grid relay protection and fault information management system. Background technique [0002] When the power system fails or is disturbed, the microcomputer relay protection device will record relevant data and information. The traditional way for the power grid dispatcher to obtain these data is: the relay protection device at the plant station outputs a paper-based action report through a printer, and then provides the report to the dispatcher by telephone and fax. The disadvantage of this method is that the data obtained by the dispatching end is slow, and this data cannot be integrated with the data obtained by other systems for comprehensive analysis of power grid faults. With the increasing level of power system automation, many domestic power grid companies have actively carried out the construction and ...

AI Technical Summary

Problems solved by technology

[0003] During the construction of the power grid relay protection and fault information management system, the incomplete and non-standard remote transmission information of the products of various protection manufacturers has become the primary problem restricting the construction of the system

In the system construction, due to the unclear positioning of the protection information remote transmission function, and the traditional protection communication protocol cannot effectively support the transmission of protection information, when the protection device operates, only a few key information can be transmitted remotely, and the master station receives The received data is extremely limited, and the content of the action report formed at the master station is far from that printed on the spot by the protection device, which brings inconvenience to the analysis of power grid faults at the dispatcher end, and eventually leads to the construction of a domestic relay protection fault information management system Less practical

In a sense, the original information access method has affected the practical level and implementation effect of the power grid relay protection and fault information management system to a certain extent.
