Embodiment Construction
[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the specific embodiments and the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concepts of the present invention.
[0041] like figure 1 As shown, the valve tower is connected to the controlled capacitor as a separate bypass for the capacitor. According to the difference of voltage level and transmission capacity, different numbers of IGCT valve components are used to assemble to meet the needs of different capacitance compensation capacity.
[0042] combine figure 2 , IGCT valve components can be connected in series with different stages of IGCT val...

The invention relates to an IGCT valve tower structure of an extra-high voltage direct current transmission capacitor strong compensation device and an installation method. The IGCT valve tower structure comprises a plurality of IGCT valve assemblies and supporting insulators. The IGCT valve assembly is provided with an independent closed cabin body and can be supported by supporting insulators and longitudinally arranged to form multiple layers of valve towers, two or more rows of valve towers are arranged in parallel, and the overall stability of the valve towers is enhanced; the interior of the valve tower is formed by connecting a plurality of IGCT valve assemblies in series, the wire inlet and outlet ends on the two sides are connected in a spiral ascending or descending mode through a through-flow row, the wire inlet and outlet ends of the IGCT valve tower structure are merged into a part of capacitor loops for reactive compensation in an alternating current system, and the capacitor switching number is controlled. Modularized design of assemblies is convenient to assemble, the whole valve tower is of a three-dimensional layered supporting structure, and space and occupied area are greatly saved. The used components and IGCT valve assemblies are high in protection level and pollution resistance level, can be directly used in the outdoor environment, save the construction cost and reduce the occupied area, and are suitable for transformation of existing projects.
Description
technical field [0001] The invention relates to the field of ultra-high voltage direct current power transmission, in particular to an IGCT valve tower structure and an installation method of an ultra-high voltage direct current power transmission capacitor reinforcement device. Background technique [0002] In AC systems, a combination of capacitors and reactors is often used for reactive power compensation. Under normal operating conditions, this compensation method is fixed compensation. Although it has the advantage of a wide range of compensation capacity, it has the disadvantage that the compensation capacity is not easy to adjust. [0003] In order to realize the adjustment, it is necessary to control part of the capacitor switching to meet the structural form of the capacitor reinforcement device for fast reactive power dynamic adjustment of the system. SUMMARY OF THE INVENTION [0004] In view of the problems existing in the prior art, the present invention prov...
