City center area power distribution network and load transfer method

Abstract

The invention discloses a city center area power distribution network. Buses of a first switch station bus, a second switch station bus and a third switch station bus are respectively preset with a private line connection position, every two of the private line connection positions of the first switch station bus, the second switch station bus and the third switch station bus are in circuit connection through connection wires, and a first transformer station bus, a second transformer station bus, a third transformer station bus and a fourth transformer station bus form two main configurations and two standby configurations. The power distribution network employs grid design thinking, a corresponding target wiring load transfer strategy analysis model is established, power supply capacity and reliability requirements of important users are satisfied, and transfer scheme making efficiency of regulators and operators is improved.

Description

technical field [0001] The invention relates to an urban power distribution technology, in particular to a distribution network in a city center area and a load transfer method. Background technique [0002] With the improvement of people's quality of life, some new problems are gradually exposed in the traditional distribution network planning: the busbar of the substation in the urban center tends to be saturated; the load level of equipment is high; Pipeline congestion; lagging development of distribution automation, etc. [0003] Based on the above problems, the grid planning concept of distribution network is proposed. That is to manage the distribution network with the grid as the unit, including the planning, construction, operation and maintenance of the distribution network. This management method can provide decision-making basis and reference for distribution network expansion, project reserve, reliability management, line loss management, basic ledger managemen...

Problems solved by technology

[0002] With the improvement of people's quality of life, some new problems are gradually exposed in the traditional distribution network planning: the busbar of the substation in the urban center tends to be saturated; the load level of equipment is high; Pipeline congestion; development of distribution automation lags behind, etc.

[0010] However, since the urban distribution network structure is more complex than that in general areas, in order to meet the power supply capacity and reliability requirements of important users, the connections between different
