Abstract

The invention discloses a bypass system for improving SVG reliability. The bypass system comprises an SVG power unit automatic bypass unit, a one-to-two unit and an electromechanical combined controlbypass contactor unit. The SVG power unit automatic bypass unit, the one-to-two unit and the electromechanical combined control bypass contactor unit are connected in parallel. According to the bypasssystem for improving SVG reliability, no shutdown is needed under a fault, fault link bypass shielding can be automatically completed, and the continuous operation time of equipment is greatly prolonged; and the control circuit is greatly simplified, the bypass reliability is improved, and the engineering practical value is improved.

Description

technical field

[0001] The invention relates to the field of power quality management, in particular to a bypass system for improving the reliability of SVG. Background technique

[0002] Static Var Generator, described in English as: Static Var Generator, referred to as SVG. Also known as high-voltage dynamic reactive power compensation generator, or static synchronous compensator. It refers to a device for dynamic reactive power compensation by a self-commutated power semiconductor bridge converter. SVG is currently the best solution in the field of reactive power control. Compared with traditional condensers, capacitor reactors, and traditional SVC mainly represented by thyristor-controlled reactors TCR, SVG has incomparable advantages.

[0003] Since these products require long-term, continuous and stable work, and most of the equipment is scattered in complex areas such as coastal areas, mountainous areas, grasslands, and Gobi, most of the on-site traffic conditions ...
