Abstract

The invention provides an inter-station communication method for stability devices. The method comprises the steps: building tunnel communication connection between a first stability device and a second stability device based on a VPLS network, wherein the first stability device transmits a GOOSE message through PE router multicast, the GOOSE message comprises a VLAN and a VLAN ID where the firststability device is located, and removing the VLAN information after receiving the GOOSE message and judging that the first stability device is located according to the VLAN ID, and forwarding the GOOSE message from which the VLAN information is removed to the second stabilizing device in the corresponding VLAN. According to the scheme, tunnel communication based on the IEC61850 stability device is achieved by deploying a VPLS network, point-to-multipoint communication of the stability devices is achieved, information closed loop can be avoided, delay caused by message forwarding is reduced, and safety and reliability of data transmission can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of substation communication, in particular to a method and system for inter-station communication of a stabilization device. Background technique [0002] As a key component of the second line of defense of the power grid, the stabilization device reduces the scope of the accident, avoids the development of cascading failures, and ensures the stable operation of the system through measures such as machine cutting and load shedding. The second edition of IEC61850 extends the communication within substations to between substations, providing a new solution for realizing wide-area, fast and orderly coordination between stable devices. As the scale of the grid continues to expand, especially the inter-regional grid interconnection promotes grid connectivity and increases the risk of large-scale blackouts caused by cascading failures. By analyzing the major power outages that have occurred at home and abroad in ...
