天广交直流输电系统对广东电网影响研究

Researches of Tian-Guang AC and DC hybrid transmission system influence upon Guangdong network

分析了 2 0 0 3年南方电网各运行方式下 ,天广交直流混合输电系统中广东电网潮流分布特点 ,提出了广东电网潮流控制原则和运行要求。在潮流分析的基础上 ,研究了夏大及冬大正常方式下天广交直流系统输送功率极限及影响天广通道广东入口断面极限功率的主要因素。

This paper analyzes the characteristic of power flow of the Tian-Guang AC and DC hybrid transmission system at each operating modes of Southern China network in 2003. The controlling principle of power flow and the demand to operation of Guangdong network are presented. Based on the analysis of power flow, the power limit of the hybrid system and the main factors influencing the limit power of the Guangdong entry section of Tian-Guang channel are studied.
