摘要
Abstract
In impulse voltage,equalizing the voltage of the various thyritors is the key. With the number of the thyristors in the ultra high voltage direct current (UHVDC) valve increasing, the bias of voltage enduring by various thyristors is more apparent. This paper put forward the equivalent simplified method of HVDC valve with many conductors and complex circuit network. Several voltage balancing schemes of HVDC converter valve were advised, such as installing the equal voltage capacitor, choosing the scattered shielding system and concentrating all of the satural reactors in the whole valve, and the adverse effect and advantage of the schemes were analyzed. In the real valve tower, the distribution and concentration of the satural reactor arrangement scheme were formed, and the voltage of the first and last thyristor were measured, which means the concentration of the satural reactor adduces the better voltage distribution.关键词
