Electric energy distribution system and a distribution method based on an intelligent electric room

Abstract

The invention provides an electric energy distribution system and a distribution method based on an intelligent electric room. The electric energy distribution system comprises a distributed photovoltaic power station, a factory photovoltaic power station, a step-up transformer, an intelligent electric room and a grid-connected cabinet. A switch electric cabinet, a metering electric cabinet and asummary electric cabinet are arranged in that intelligent electric room; The distributed photovoltaic power station comprises a plurality of residential roof photovoltaic power stations; The distributed photovoltaic power station, the booster transformer, the switch cabinet and the metering cabinet are electrically connected in turn, and the factory photovoltaic power station, the metering cabinetand the grid-connected cabinet are electrically connected with the aggregation cabinet; The summary cabinet is used for summarizing and monitoring the power generation quantity, and distributing andtransferring the power quantity to the grid-connected cabinet; The grid-connected cabinet is used for controlling the transmission of electric energy to the electric equipment or the utility grid of the factory according to the electric situation of the electric equipment of the factory. The distribution system and the distribution method can make the electricity of the photovoltaic power stationon the roof of the residents around the factory be more fully utilized, and can reduce the electricity cost of the factory at the same time.

Description

technical field [0001] The invention relates to the technical field of electric power grids, in particular to an electric energy distribution system and distribution method based on an intelligent electric room. Background technique [0002] The electricity consumption of factories in industrial areas is of a commercial nature and consumes a lot of electricity, so the electricity bills are relatively expensive. In order to reduce these expenses, many factories will choose to install photovoltaic power stations on the roof to reduce electricity consumption. However, under normal circumstances, photovoltaic The power generation of the power station often cannot meet the needs of the factory building. This is because the power generation of the photovoltaic power station is affected by the weather, the structure of the roof, and also affected by the surrounding obstacles to varying degrees. Although the power generation of the factory building is greatly reduced. The power cons...

[0002] The electricity consumption of factories in industrial areas is of a commercial nature and consumes a lot of electricity, so the electricity bills are relatively expensive. In order to reduce these expenses, many factories will choose to install photovoltaic power stations on the roof to reduce electricity consumption. However, under normal circumstances, photovoltaic The power generation of the power station often cannot meet the needs of the factory building. This is because the power generation of the photovoltaic power station is affected by the weather, the structure of the roof, and also affected by the surrounding obstacles to varying degrees. Although the power generation of the factory building is greatly reduced. The power consumption of the public grid, but generally for the factory building, the power is still not enough in many cases

[0003] With the general trend of energy saving and emission reduction, more and more ordinary families will install photovoltaic power stations on their roofs, because it can not only play the role of sunshade and heat insulation, but also generate electricity for their own use. Since the electricity consumption of ordinary families is not large, Often there will be excess electricity, and these excess electricity will enter the public grid, which shows that the electricity of these photovoltaic power plants cannot be fully utilized
