A distribution method of electric energy distribution system based on intelligent electric room

Abstract

The invention provides a distribution method of an electric energy distribution system based on an intelligent electric room. The electric energy distribution system includes a distributed photovoltaic power station, a factory photovoltaic power station, a step-up transformer, an intelligent electric room, and a grid-connected cabinet; There are switch cabinets, metering cabinets and summary cabinets; the distributed photovoltaic power station includes several residential rooftop photovoltaic power stations; the distributed photovoltaic power station, step-up transformer, switch cabinet, and metering cabinet are electrically connected in sequence. The photovoltaic power station, metering cabinet, and grid-connected cabinet of the factory mentioned above are all electrically connected to the summarizing cabinet; Control the transmission of electric energy to the factory's electrical equipment or the public grid according to the power consumption of the factory's electrical equipment. The distribution system and distribution method can make full use of the electricity of the photovoltaic power stations on the rooftops of the residents around the factory, and at the same time reduce the electricity cost of the factory.

Description

technical field [0001] The invention relates to the technical field of electric power grids, in particular to a distribution method of an electric energy distribution system 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 con...

[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
