摘要
云南电网2013年除已有楚穗直流外、溪洛渡直流、糯扎渡直流陆续投运,届时将形成多回直流同时运行,同时形成交强直弱的模式交直流混合运行模式。在研究云南多回交直流混联电网送出存在的问题基础上,提出了云南与外网纯直流联网的构想,并通过直流联网和交直混合联网的对比分析计算,讨论了直流联网的可行性。
In Yunnan power system, the xiluodu DC system and nuozhadu ultral DC transimission system is going to be on operated, in addition with the chusui uhral DC transimission system. At that time, there will be multi - DC system being operated at the same time. Strong DC system and weak AC system situation will be formed. It is a new challenge for the dispatch and operation of yunnan power system. This paper propose a DC transmission connected with external system mode, based on the AC - DC hybrid power sys- tem transmission problem. The possibility of interconnection with external system by DC transmission system is discussed through the comparison between DC system interconnection and AC -DC hybrid interconnection.
