Introduction of China National Control Center;中国电网概况 Overview of Power Grid in China ;中国电网的发展历史 Development of Power Grid in China;输电线路电压等级的发展 Evolving of Voltage Level on Transmission Lines;总装机 Total 438.8GW 火电 Thermal 327.3GW 水电 Hydro 103.8GW 核电 Nuclear 6.8GW 其它 Others 0.9GW;中国目前最大单机容量The Largest Generator Units in China;截至2004年底，国网公司所属220kV以上电压等级线路总长达17.7252万公里。 By the end of 2004, the total length of transmission lines at 220kV and above within SGCC is about 177,252km. 其中330kV和500kV电压等级线路5.0176万公里。 Among them, 50,176km lines at 330kV and 500kV. 2005年9月26日，中国第一条750千伏交流线路（140.7km）开始运行。 On Sept. 26th, 2005, the first 750kV AC transmission line, which is 140.7km long, was commissioned.;装机迅速发展 稳定水平不断提高Installed Generating Capacity Increases Rapidly with Improved Power System Stability;跨区送电情况 Inter-regional Power Transmission ;最近三年全国日发电量曲线 Daily Generation Curves of China in Recent 3 Years;2005年电网最高用电负荷The Peak Load in 2005;三峡水电厂由国调直接调度，是目前中国最大的水电厂。现有14台机组，总装机容量9800MW。全部建成后装机容量将达到18200MW。 Three gorges hydro-power plant, the largest hydro-power plant in China, is dispatched by NCC directly. With 14 sets of generation units, its total generating capacity is 9800MW at present, and will reach 18200MW when the whole project is finished. 三峡的建设促进了全国联网和电网建设的大发展 The Three Gorges Project promotes the growth of interconnection among regional grids in China, as well the power grid construction.;;中国电力调度机构 Power Control Centers in China;国调NCC;国家电网公司调度管理采取“统一调度，分级管理”的模式，有效的保证了中国电网的安全稳定运行。近年来电网负荷每年以10％以上的增长率迅速提高，但国家电网公司自1997年来未发生过稳定破坏事故。 The mode of unified dispatching and hierarchy administration is adopted for the dispatching administration in SGCC to ensure the security and stability of power system operation in China. Although the load experienced increase of 10% or above annually since 1997, system collapse hasn’t occurred within SGCC.;国调中心机构设置 Organization of NCC;国调中心员工学历、年龄结构 Status of the employees in NCC;国调直接调度的设备The Devices Dispatched Dir
