Research on Target Framework of Pearl River Delta Power Grids
摘要
Abstract
Pearl River Delta power grids have characteristics of high load density,multi-DC feed-in and complicated framework structure,and there are problems such as excessive short-circuit current,AC/DC interaction,insufficient risk control ability,and so on.Therefore,the paper proposes to construct the target framework of Pearl River Delta power grids by taking a form of partition interconnection.Specific construction of the target framework includes 500 kV AC weak connection,1 000 kV ultra-high voltage AC and asynchronous interconnection.It also analyzes influence of partition scale and connection types on safety performance of Pearl River Delta power grids by simulating and results indicate asynchronous interconnection has advantage in fault isolation and promoting controllability of the system.关键词
