Embodiment Construction

[0020] In the present invention, the dual-ring network topology is in physical form, without considering its logical structure. For example, using cisco's StackWise technology or Huawei 3Com's IRF and other related technologies to logically virtualize two switches into a single joint device, making it a whole in terms of management and use, thereby simplifying the logical network structure and increasing the number of devices exchange capacity and reliability. At the same time, the protocol running on the switch, such as STP protocol or various Ethernet ring network protocols such as REP, EAPS, RRPP, etc. is not considered.

[0021] The actual connection mode between the regional switches of the present invention can be a leased transmission network line of an operator or a dedicated network built by oneself.

[0022] The following is a preferred embodiment of the present invention, including the network connection and configuration of the prefecture-county integration sys...

Abstract

The invention discloses a transregional double ring network topology of an electric power dispatch automation system, which is mainly used in a transregional dispatch automation system and is characterized in that all regions are respectively provided with two exchangers of an exchanger I and an exchanger II which are respectively connected with exchangers I and exchangers II of two adjacent regions, all exchangers I in all regions form a loop, and all exchangers II form the other loop, and the two exchangers in each region are mutually connected. The invention meets the requirements for electric power dispatch automation two-network redundancy and disaster tolerance backup, and can achieve the purposes of flexible construction and cost saving.

Description

[0001] technical field [0002] The invention relates to a networking mode for a cross-regional power dispatching automation system, which can save network costs, realize network redundancy, and meet the requirements of data collection and monitoring in power dispatching. The invention belongs to the field of power dispatching automation. Background technique [0003] The domestic power grid operation implements the principle of unified scheduling and hierarchical management. The dispatching agencies are divided into five levels: national, grid, provincial, prefectural, and county. Dispatching agencies at all levels are equipped with independent dispatching automation systems. The two systems share power grid production data through data forwarding. With the development of electric power dispatching automation technology, it is difficult for the independently constructed prefectural and county dispatching automation systems to meet the needs of development. In order to rea...
