Site selection method for power grid energy saving and consumption reduction in industrial park residential area

Abstract

The invention discloses an energy-saving and consumption-reducing power station site selecting method for a power grid in a residential district of an industrial park and belongs to the technical field of power transmission and distribution engineering. The energy-saving and consumption-reducing power station site selecting method for the power grid in the residential district of the industrial park comprises the steps that the virtual load centers of two point loads are obtained in pair according to the annual power consumption of all point loads in the industrial park, and convergence is conducted step by step till the load center of the industrial park is approached; then, the site of a power station is selected compressively according to an urban construction plan and social production and development by avoiding geographical limitation. By the adoption of the energy-saving and consumption-reducing power station site selecting method for the power grid in the residential district of the industrial park, the overall wire diameter of the power grid in the industrial park can be smallest, power grid construction investment is lowest, and operating line loss is smallest; the virtual load centers are obtained based on a selected conductor cross section computational formula and accord with the power scientific law. The method is used for selecting the site of the power station in the residential district of the industrial park and can also be used for selecting the site of a step-down substation of a power distribution network in a social power grid.

Description

technical field [0001] Transmission and distribution engineering. Background technique [0002] The power supply from the social grid to the residential area of ​​the industrial park is supplied to the power station in the residential area of ​​the industrial park with the rated distribution network voltage. The power station in the residential area of ​​the industrial park is reduced to a line voltage of 380V and a phase voltage of 220V, and then passed through the residential area of ​​the industrial park. The power grid in the park is sent to each point load in the park. Power grid line transmission must have road loss, which accounts for 5-10% of the total power supply. The scientific allocation of power stations in the residential area of ​​the industrial park can firstly save the investment in the construction of the power grid lines in the park, and more importantly, the power loss of the power grid in the park can be significantly saved, and the reduction of the roa...

Problems solved by technology

Site selection is based on power factors. Although it is already known that the power station should be built in the load center of the load surface (industrial park residential area), due to the lack of applied mathematical means in today's "big data era", the geographical center of the park is often used instead of the load center, resulting in The power grid in the park has a large road loss
