摘要

针对空间天气干扰下地磁感应电流对电力系统电力变压器保护系统的影响进行了研究。所提出的系统的主要元件是一个高压半导体键。该保护系统由最少数量的半导体元件组成，并通过在光电晶闸管基座上实现的最简单的电源方案来实现。提出了一种完全阻断或限制低强度地磁感应电流的电力变压器保护系统。

Special Aspects of Neutral Grounding System of Power Transformers with Photothyristors During Space Weather Disturbances

Identified the protective system of power transformer of electric power system from the influence of geomagnetically induced currents during space weather disturbances. The main element of the system that has been suggested is a high voltage semiconductor key. The protective system consist a minimum quantity of semiconductor elements and fulfilled by the most simple power scheme which is implemented on the photo-thyristor base. Protective system of power transformer which was suggested allow fully block or limit to a low level intensity of geomagnetically induced currents.
