Dynamic Stability Characteristics and Control Strategies of the UHV System in Initial Operation Period

This paper analyzes the new situation faced by operation and control of the ultra high voltage (UHV) system when it was put into operation. This UHV system consists of North China power grid and Central China power grid. They are interconnected by UHV AC tie lines, and both of them have an installed generation capacity of over 100 GW. Additionally, this paper studies the dynamic characteristics of the UHV system and provides effective operation and control measures for dynamic stability problems with the UHV system in its early operation period. The results from the above analysis and study play an important guiding role in planning, designing, operating and controlling the UHV AC interconnected power grids.
