Embodiment 1

[0028] Such as figure 1 As shown, the GOOSE message implementation method of the present embodiment includes the following steps:

[0029] S1. Determine the information to be subscribed and released according to the remote signaling, telemetry, remote control and remote adjustment functions realized by the traditional electric power microcomputer experimental equipment (microcomputer device), where the information to be subscribed refers to all the switch state information or control to be received Command, the information to be issued refers to the status information or control command of the switch to be sent, so as to determine the GOOSE message subscription item Input and the data set DataSet;

[0030] In step S1, it is assumed that there are m channels of switching value state information to be received, and these m channels of switching value state information form a GOOSE message data set DataSet in sequence, and each channel of switching value state information include...

Abstract

The invention discloses a GOOSE message implementation method applied to a traditional microcomputer experiment device. The GOOSE message implementation method comprises the steps of determining information to be subscribed and issued according to functions achieved by the traditional microcomputer experiment device, determining GOOSE message subscription entries and a data set, generating reference formats of GOOSE message subscription messages and issue messages of the traditional microcomputer experiment device according to a control module name and network parameter configuration of the traditional microcomputer experiment device in an offline mode, downloading the reference formats of the messages to the traditional microcomputer experiment device for packet sending and packet decompression, performing GOOSE message decompression based on information position and a GOOSE message receiving template, performing GOOSE message packetization based on the information position and the GOOSE message receiving template, enabling the traditional microcomputer experiment device to resend GOOSE messages with the dame data set contents at set time intervals in a timed mode. The GOOSE message implementation method can meet the digitization requirements of smart power grids.

Description

technical field [0001] The invention relates to a GOOSE message realization method, in particular to a GOOSE message realization method suitable for traditional microcomputer experiment equipment. It belongs to power system protection, control and automation technology. Background technique [0002] In the power system communication network, GOOSE (Generic Object Oriented Substation Event) messages are mainly used to represent important occasions such as operating commands such as tripping and closing of circuit breakers and circuit breaker position information. The controller used in the traditional electric power microcomputer experiment equipment has low performance, and the basic message processing and communication capabilities are weak. Object-oriented, ASN.1 abstract syntax markup dynamic parsing and coding methods used to realize the IEC 61850 standard GOOSE message are difficult to implement in traditional power microcomputer experimental equipment, resulting in th...
