摘要
2005年随着灵宝背靠背直流输电系统的投入运行,我国在运的高压直流输电系统已达到6条,总输送容量12360MW。2005年总输送电量约612．11亿kW·h,直流输电已经成为跨区电网间电力交换的主要方式。主要对三峡外送葛洲坝—南桥、龙泉—政平、江陵—鹅城超高压直流输电系统2005年的运行情况进行了分析,列举了2005年直流系统中出现的较大设备事故和可靠性指标数据以及一些反事故措施,并提出有关建议。论述直流输电系统运行情况,供电力系统设计和运行维护参考。
In 2005 Ling-Bao Back-to-back HVDC transmission system have put into service, at present in China there are total six HVDC transmission projects in service, and the total transmission capacity is 12.36 GW. In year 2005 delivered energy is 61.211TW. h, so HVDC transmission has become the main power exchange means among grids. In this paper the operation of the Three Gorges output HVDC transmission system （C, ezhouba-Nanqiao, Longquan-Zhengping, Jiangling-Echeng） in 2005 is described. Some important equipment damages, reliability datas and corresponding countermeasures are analyzed. At last some suggestions are proposed. The evaluate will be referred by other power system designs ,operation and maintence.
