Embodiment Construction

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific implementations of the present invention are now described. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention, that is, the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0028] Taking the AC filter field of a UHV converter station as an example, the converter station has 11 filter groups and 5 groups of shunt capacitors. If the improved "Tian"-shaped layout structure is adopted, it includes G101-AC filter group, G102-parallel capacitor group, G201-grounding switch 1, G...

Abstract

The invention relates to the technical field of AC distribution networks, and discloses an alternating current filter field arrangement structure with optimized arrangement. An alternating-current filter area power distribution device is arranged in a double-layer wire mode, the upper layer comprises an alternating-current filter first large-group bus and an alternating-current filter second large-group bus, the lower layer comprises an alternating-current filter small-group bus, and the alternating-current filter small-group bus is connected with the alternating-current filter first large-group bus through a down lead. The filter power distribution device is connected with an alternating current filter group bus through a down lead, and the alternating current filter group and the parallel capacitor group are connected with the filter power distribution device through the equipment connecting wires. According to the invention, the equipment type selection is optimized, and a three-column type common static contact isolating switch is adopted, so that the arrangement structure is improved, the lengths of two improved large-group bus frameworks shaped like a Chinese character of tian are shortened. The two rows of frameworks are combined into the same row for arrangement, and a second large-group incoming line of the alternating current filter extends into the center of the alternating current filter field through an GIS device to be connected with a second large-group bus.

Description

technical field [0001] The invention relates to the technical field of AC power distribution networks, in particular to an optimally arranged AC filter field layout structure. Background technique [0002] In the UHV converter station, according to the requirements of system reactive power balance and suppression of AC side harmonics, there are multiple sets of AC filter banks and parallel capacitor banks, which are one of the important components of the ±800kV UHV converter station. The AC filter site It accounts for about 30% to 40% of the entire converter station site. The layout of the AC filter site will directly affect the size of the general layout of the converter station, and is related to many key elements of the project, such as project investment, equipment and personnel safety, operation and maintenance. Therefore, reasonable optimization and research on filter site layout has very important engineering value and research significance for reducing the total are...
