摘要

500kV藏中联网工程投运后，西藏电网与西南主网联为一体，解决了长期困扰西藏地区的缺电问题。然而，联网初期由于长链式交流通道稳定水平低和柴拉直流与交流通道交互等因素的影响，西藏电网产生了新的安全稳定问题。本文针对藏中联网工程投运后存在的典型安全问题进行分析，如柴拉直流与交流通道交互影响、西藏电网负荷特性对藏中孤网的影响，及500/220kV电磁环网的影响，讨论其安全稳定控制策略。

Abstract

After the 500kV Central-Tibet interconnection project was put into operation

the Tibet Power Grid and the Southwest Power Grid were integrated to solve the problem of power shortages that have long plagued Tibet. However

due to the low level of stability of long-chain AC channels and the interaction of Chaila HVDC and AC channels

the Tibet Power Grid has created new security and stability problems. This paper analyzes the typical security problems existing after the operation of the Central-Tibet interconnection project

such as the impact of the interaction between the Chaila HVDC and AC channels

the impact of the load characteristics of the Tibet Power Grid on the isolated network in Tibet

and the impact of the 500/220kV electromagnetic ring network. And discuss its security and stability control strategy.
