摘要
水力资源是中国重要的能源资源,随着我国电压等级的提高,大容量、大尺寸、高可靠性水电机组将以应用,目前百万千瓦级水电机组以单位造价和发电成本低的优点已得到广泛共识,并对其新技术、新结构、新材料等进行研究。文章着重分析了百万千瓦水电机组的绝缘问题,针对机组本身价值较高,非正常停机损失大及保护、设计、运行等方面的新特点,提出了机组绝缘的新要求。
Hydraulic energy resource is an important resource of our nation, and the large capacity, large size and high reliable hydraulic power units will be applied along with the increase of voltage levels, I000MW units have some obvious advantages with low unit cost and generation cost, and some study has been prosecuted on its new technology, new structure and new materials. The paper detailed analyzes the isolation problem of I000MW units, and proposes new requirement on units isolation aiming at the problem of higher price of units, large loss of abnormal outages, and some new character on protection, design and operation.
