Smart substation signal generator that integrates network traffic and grid business data

Abstract

The invention discloses an intelligent substation signal generating device fusing network traffic and grid service data. A CPU (Central Processing Unit) module is used for generating network traffic configuration data and a control command, outputting the network traffic configuration data and the control command to a network traffic generating module to generate grid service data, and controlling the grid service data to be sent or not sent to a data fusion module. The network traffic generating module is used for outputting network traffic data to the data fusion module according to the network traffic configuration data under the control of the control command. The data fusion module is used for fusing the grid service data and the network traffic data and outputting the fused data to a code sending module to output the fused data to the outside. By organically fusing the grid service data and the network traffic data, the device can output two types of data signals to a network system of a process layer and a station control layer of an intelligent substation to test the behaviors of the network system of the intelligent substation and network equipment under different traffic, thereby solving the problem that network test equipment and relay protection test equipment adopted in the practical network testing process cannot effectively coordinate the overall network traffic.

Description

technical field [0001] The invention relates to the field of intelligent substations, in particular to an intelligent substation signal generating device for integrating network flow and power grid business data. Background technique [0002] The smart substation adopts a three-layer and two-network network architecture. Secondary equipment such as relay protection devices, measurement and control devices, and metering devices rely on the secondary network to work. transmission. At present, the network switching equipment of the smart substation is tested by a network tester. During the network load capacity test, general network traffic data such as IP, UDP, and ARP can be output. Functional tests of secondary equipment such as relay protection devices, measurement and control devices, and metering devices are generally tested by relay protection testers, which output power grid business data such as SV and GOOSE, and the two test processes are carried out independently. ...

AI Technical Summary

Problems solved by technology

[0003] The above actual situation has the following direct safety hazards: (1) The work of the secondary equipment of the smart substation is heavily dependent on the network, and the general network traffic data such as IP, UDP, and ARP in the network load capacity test are different from the actual message environment of the smart substation. Large differences, unable to simulate the real secondary equipment network message environment in power grid operation

(2) The network load capacity test is disconnected from the secondary equipment function test. How to effectively test the action behavior of the secondary equipment on the network under the network load cannot be ignored in the safe operation of the smart substation. The above network tester and relay When the protection tester works at the same time, there is a difficulty in reasonably coordinating network traffic and power grid business data traffic
