Endeavor in efficiency and security, we buildup a system of standard procedures. Decompose the operation business into independent tasks, then establish standard business procedures for every task in details. E.g. switching operation, combined monitoring, and joint fault dispose, etc. * Overview of SGCC and the Integration of Large Wind Power 国家电网概况及大规模风电并网运行情况 National Electric Power Dispatching and Control center State Grid Corporation of China September , 2013 国家电力调度控制中心 中国国家电网公司 2013.09 2. Integration and Operation of Large Wind Power 大规模风电并网运行 Overview of SGCC 国网概况 3. Problems We Have Interests in 下一步工作展望 19 Overview of SGCC 国网概况 SGCC’s core business is to build and operate power grids, the service area covers 26 of 31 provinces, takes 88% of China’s territory, SGCC is the biggest utility company worldwide. 作为世界上最大的公用事业企业，国家电网主营业务是建设和运行26个省级电网，经营范围覆盖了国土面积的88%。 (unit GW) The steady growth of China’s national economy leads to the continuous increase of electricity demand and installed capacity at a fast speed. By the end of 2012, total installed capacity and gross generation reached 882GW and 3876TWh respectively. The first is thermal power, takes 74% and the second is hydro power, takes 19%.The wind power increased fast and exceeded 56GW, takes 6.3%. Installed Capacity 装机容量 得益于中国经济的稳定增长，社会用电需求和发电装机容量快速增长。2012年底，国网经营区域内发电装机容量达到8.82亿千瓦时，其中火电占74%，水电19%，风电装机5636万千瓦，占6.3%。2012年总发电量38761亿千瓦时。 Load Level 负荷水平 西藏电网 East China 华东 North East 东北 SCG 南方电网 C/L 112GW/52GW C/L 123GW/66GW C/L 248GW/149GW Installed Capacity and Peak Load 201GW/188GW C/L 243GW/215GW Tibet 西藏 North China 华北 North West 西北 Central China 华中 By the end of August 2013, installed capacity in SGCC was up to 927GW, and max peak load reached 654GW. 截至2013年8月底，国网经营区域内发电装机容量达到9.27亿千瓦，最大负荷达6.54亿千瓦。 * Dec., 1987 ±100kV DC Nov., 2011 ±400kV DC Sep., 1989 ±500 kV DC Feb., 2011 ±660 kV DC Jul., 2010 ±800 kV DC Jan., 1954 220kV AC Jun., 1972 330kV AC Dec., 1981 500 kV AC Jan., 2009 1000 kV AC Sep.,
