摘要/Abstract

摘要： 中国能源资源与生产力逆向分布，能源基地距离负荷中心1 000~4 000 km，必须实施能源大范围优化配置，才能保障能源供应。“十三五”期间，特高压步入加速发展的快车道，国家电网（不含南网）将形成“三送端（西北、东北、西南）、一受端（华北—华中—华东）”的规划电网格局，将出现交直流并列运行、多直流集中馈入受端等特征。直流输送容量的提升和大容量特高压变压器的应用使电网安全稳定性面临新的挑战，多回直流集中送电“三华”负荷中心也对送端电网的频率稳定水平提出了更高的要求。依托国家电网仿真中心，从短路电流、静态安全性、暂态稳定性、动态稳定性、电压稳定性等方面进行安全校核，结果表明，通过构建“强交强直”电网格局、采用交直流协调控制策略、适时解开1 000/500 kV电磁环网等对策，可有效解决国网“十三五”规划电网面临的主要安全稳定问题。

Abstract: Due to the inverse distribution of energy resources and productivity in China, the energy bases and the load centers are about 1 000 to 4 000 kilometers apart from each other, which needs a wide range of optimal energy allocation to ensure energy supplies. During the 13th Five-Year period of power grid planning, UHV will have entered a rapid development period. The planned national grid (excluding Southern power grid), which has a structure of three sending ends(i.e. the Northwest, Northeast and Southwest power grids) and one receiving end(North China-Central China-East China UHV synchronous power grid) will take shape and features AC/DC hybrid power and multi-infeed HVDC systems. The power stability will face new challenges due to the upgrade of DC transmission capacity and the application of large capacity UHV transformers. Higher requirements on the frequency stability of sending power grids are put forward owing to the concentrated multiple HVDC transmission to the load centers. The security assessment in aspects of short circuit current, static security, transient stability, dynamic stability and voltage stability made by the State Grid Simulation Center indicates that the main security and stability issues faced by the 13th Five-Year power grid planning will be effectively solved by the following countermeasures including the construction of strong AC and strong DC power grid structure, the adoption of AC/DC coordination control strategy and the timely breakup of 1 000/500-kV electromagnetic looped networks.

Key words: 13th Five-Year period, evaluation of planning, UHV power grid, security and stability
