Power distribution network integrated terminal equipment

Abstract

The invention discloses a power distribution network integrated terminal device, which comprises a virtual switch, an external interface and a plurality of container systems; each container system is electrically connected with the virtual switch, and the virtual switch is electrically connected with the external interface; the container system comprises a collection container system, a basic service container system, an operation and maintenance container system, a protection container system and a control container system; the operation and maintenance container system realizes power distribution network operation and maintenance service; the protection container system realizes power distribution network protection service; and the control container system realizes power distribution network control service. According to the scheme, strong coupling of software and hardware is decoupled in a software definition mode, protection, control and operation and maintenance service functions can be integrated, equipment investment, deployment and operation and maintenance requirements are reduced, terminal computing resources of the power distribution network are flexibly configured, terminal functions are flexibly deployed, the diversified service requirements of the power distribution network are met, the number of power distribution network terminal equipment is reduced, and the operation reliability and the operation and maintenance efficiency of a power distribution network automation system are improved.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a distribution network integrated terminal device. Background technique [0002] With the mass access of distributed new energy, electric vehicles, and elastic loads on the side of the distribution network, the wide range of access points, the volatility of renewable energy output, and the randomness of load power consumption have brought great challenges to the distribution network. Higher requirements are put forward in terms of protection, control, and operation and maintenance. [0003] The existing distribution network usually adopts traditional schemes when realizing protection, control, and operation and maintenance functions, that is, protection, control, and operation and maintenance functions are realized by using protection equipment, control equipment, and operation and maintenance equipment respectively. They are independent of each other, resulting in informati...

Problems solved by technology

[0003] The existing distribution network usually adopts traditional schemes when realizing protection, control, and operation and maintenance functions, that is, protection, control, and operation and maintenance functions are realized by using protection equipment, control equipment, and operation and maintenance equipment respectively. Independent of each other, resulting in isolated islands of information and difficulty in operation and maintenance, and also reduces the overall reliability of the distribution network automation system

[0004] At present, the protection equipment, control equipment, and operation and maintenance equipment of the distribution network are all systemized and constructed separately. The interoperability between the equipment is poor, and there are problems of repeated investment, information islands, and heavy operation and maintenance workload; It is impossible to share data between them, the relevant cooperation is insufficient, the operation of the system cannot be tracked, and there are even problems such as protection mismatch. It is difficult to meet the requirements of massive equipment access and complex operation modes in the distribution network under the new situation.
