Power distribution network frame optimization method based on energy internet

Abstract

The invention relates to the technical field of power grid erection, and discloses a power distribution network frame optimization method based on energy internet. The method comprises the following steps: A, field investigation of a power grid erection site; B, acquisition of power grid erection original data; C, power grid erection simulation for building a simulation experiment; D, verifying the feasibility of the power grid erection construction mode; E, designing of a power grid erection construction scheme; F, optimization design of a power grid erection scheme; and G, erecting of a power grid. According to the power distribution network frame optimization method based on the energy internet, specialized attention needs to be given from model selection of power distribution network lines, configuration of electrical equipment and determination of a wiring mode by using scientific optimization technologies and optimization measures, the modification strength of the power distribution network is improved, a high-quality and high-efficiency running power distribution network structure is built, and meanwhile, the power grid rack can meet the faster and faster power supply demand, so the safety, reliability and economical efficiency of the power grid are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of grid erection, in particular to an energy internet-based distribution grid optimization method. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network. It includes three units of power transformation, power transmission and power distribution. The task of the power grid is to transmit and distribute electric energy and change the voltage. The transmission line is realized by using a transformer to boost the electric energy generated by the generator, and then connecting it to the transmission line through circuit breakers and other control equipment. Structural forms, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, e...
