Energy station grounding grid in high-soil-resistivity region and resistance reduction optimization method of energy station grounding grid

Abstract

The invention discloses an energy station grounding grid in a high-soil-resistivity region and a resistance reduction optimization method of the energy station grounding grid. The energy station grounding grid comprises a composite grounding grid. The composite grounding grid comprises a horizontal grounding grid and a vertical grounding grid arranged on the outer edge of the horizontal groundinggrid. The horizontal grounding grid comprises horizontal grounding conductors, the horizontal grounding conductors are arranged at unequal intervals, the vertical grounding grid comprises vertical grounding conductors, each vertical grounding conductor comprises an electrode and a pole tube, the periphery of each electrode is filled with backfill, and the upper end and the lower end of each pole tube are provided with a water absorption hole and an ion release hole used for ion exchange respectively. With application of the grounding scheme of the horizontal grounding grid and the electric iongrounding electrode, better voltage-sharing and current-dispersing effects are achieved, the grounding resistance is effectively reduced, the technical and economic indexes are optimized, the construction difficulty is reduced, the construction period is shortened, and the safe and reliable operation of the smart energy station is met.

Description

technical field [0001] The patent of the present invention relates to the field of electric power technology, in particular to an energy station grounding grid in areas with high soil resistivity and an optimization method for reducing resistance thereof. Background technique [0002] The smart energy station includes three parts: substation, data center station, and integrated energy station. It integrates the functions of substation, data center station, and integrated energy station (including energy storage station, electric vehicle charging station, and distributed photovoltaic). The integrated energy station is equipped with energy storage equipment, which can "cut peaks and fill valleys" to a certain extent, optimize the load curve, and relieve the operating pressure caused by the excessive peak-valley difference in the area. The data center needs to consume a lot of electric energy, and the construction of the same station with the substation can meet the power suppl...

Problems solved by technology

[0005] The patent of the present invention is to overcome the fact that the conventional composite grounding grid in the prior art cannot meet the grounding resistance requirements in areas with high soil resistivity, is not economical, effective and reliable enough, and the grounding short circuit fault on the side of the high-voltage substation will destroy the normal operation of communication equipment and cause personnel damage. To solve the technical problem of damage, provide a grounding grid for energy stations in areas with high soil resistivity and its resistance reduction optimization method. The grounding scheme of horizontal grounding grid + ionized grounding electrode is used to achieve better voltage equalization and flow effects, effectively The grounding resistance is greatly reduced, the technical and economic indicators are optimized, the construction difficulty and construction period are reduced, and the safe and reliable operation of the smart energy station is met.
