PTN carried multi-form wireless networking method for power distribution and utilization services

Abstract

The invention discloses a PTN carried multi-form wireless networking method for power distribution and utilization services. The method includes the following steps: constructing a PTN station at an access node, and forming an access layer; carrying out hybrid networking using the access layer and MSTP; carrying out service docking between service circuits related to power distribution and utilization projects through an interface board; in a PTN access layer of a GE ring, configuring SDH to an E1 mode and PTN to an FE mode; configuring the PTN equipment of a sink node in accordance with the MSTP manner, converting the FE service of the GE ring into an E1 system through the service board of the node, and transferring the service through an aggregation layer; making part of the PTN nodes ofthe aggregation layer use an independent networking mode, and making the PTN equipment construct a GE ring of GE / 10 separately; building a special channel for each power service in a PTN layer; carrying out service docking between the service circuits of MSTP and PTN through the GE / 10 GE group roadside of PTN; and grouping services in the entire network, and forming a PTN network constructed allwith PTN equipment in the convergence layer and in the access layer. The networking method can reduce the cost of network communication and bring great economic benefit on the basis of ensuring the security of network communication.

Description

technical field [0001] The present invention relates to the technical field related to smart grids, in particular to a PTN bearing multi-modal wireless networking method for power distribution services. Background technique [0002] The distribution grid is a very important part of the smart grid and a key link in the construction of the smart grid. The distribution network shoulders important missions such as distribution automation, power quality monitoring, and distribution operation monitoring, and the smart grid is directly oriented to the public users, carrying services such as power consumption information collection, self-service payment terminals, and smart filling. Affect the reliability of power supply to the society and the quality of electricity consumption of public life. The characteristics of the grid structure, electrical performance, and business attributes of the distribution grid determine the complexity and diversity of its intelligent construction. At...

Problems solved by technology

However, it needs to go through the public network. Based on security considerations, a firewall needs to be set up.

The APN private line method needs to set up a dedicated line from the router in the GGSN computer room of the operator to the access router of the enterprise network. The security of the dedicated line is relatively high, and there is no need to face malicious attacks on the WAN, and there is no need to configure a firewall. The communication bandwidth between them is guaranteed, but the disadvantage is that the cost is higher and the construction period may be longer

[0005] Therefore, in the process of implementing the present application, the inventor found that the existing technology cannot realize low-cost network construction on the basis of ensuring communication security, that is, the comprehensive effect of communication security and low cost cannot be achieved
