High-voltage converter station and alternating-current filter arrangement structure

Abstract

The invention relates to a high-voltage converter station and alternating-current filter arrangement structure. The high-voltage converter station and alternating-current filter arrangement structure comprises a supporting frame, a fence, an alternating-current filter group, a grounding switch and a group bus; the alternating-current filter group is arranged in the internal area of the fence, the alternating-current filter group does not need to be operated generally, and after the alternating-current filter group is arranged in the fence, the fence plays a role in protection. In addition, the group bus is located in the external area of the fence, the alternating-current filter group is located in the internal area of the fence, that is, no electrified body exists above the alternating-current filter, and the worker does not need to consider whether the electrified body exists above when located in the internal area of the fence. When the worker works outside the fence, the electrified body above needs to be considered. Besides, the distance S between the top surface of the grounding switch and the group bus is not less than 8.5 m, and the distance is in accordance with an electrical safety distance range, so that the equipment can still be overhauled and maintained under the condition that the group bus is electrified, the power failure loss can be greatly reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power transmission and distribution, in particular to an arrangement structure of a high-voltage converter station and an AC filter. Background technique [0002] As a key component of the UHV DC transmission system, the high-voltage converter station undertakes the functions of rectification and inverter. The high-voltage converter station includes converters, converter transformers, smoothing reactors, AC filters, DC filters and control and protection equipment. Among them, the main function of the AC filter, which is an important part of the high-voltage converter station, is to provide reactive power and filter out AC harmonics. In addition, AC filter banks and shunt capacitors are key equipment in UHV converter stations, which have the functions of harmonic suppression and reactive power compensation. The area of ​​the AC filter field accounts for about 30% of the area of ​​the entire high-voltage ...
