摘　　要：随着特高压交直流电网的快速发展,电网送受端、交直流、调度机构上下级间的联系日趋紧密,局部故障波及全网的风险日益增大,调度实时运行控制的难度显著增加。在此背景下,分析了特高压交直流电网实时运行控制面临的挑战及需求,梳理出以往调度控制系统在支撑特高压电网运行控制方面存在的问题及不足。在此基础上,首先设计并提出特高压互联电网一体化运行监视和故障协同处置应用功能建设的总体目标、整体框架和主要模块;然后,从特高压电网运行状态同景监视、跨区故障协同诊断、多级调度故障预案联合执行、故障信息整合和多屏联动展示、源网荷优化协调、省地负荷协同控制等方面,对其关键技术进行了分析和论证;接着,结合在特高压送受端相关调控中心的工程实践,对其实际应用效果进行了介绍;最后,讨论了特高压电网调度控制领域未来可能的发展方向和关键技术。With the rapid development of UHV AC/DC power grid, the connections between power sending-side and receiving- side, AC and DC, and the upper and lower levels of the dispatch center are becoming closer and closer. The risks that local faults spread to the whole power grid are increasing, and the difficulty of dispatching real-time operation control is significantly also increasing. In this context, the paper analyzes the challenges and needs of real-time operation control of UHV AC/DC power grid, and combs out the problems and shortcomings of previous dispatching control system for supporting the operation control of UHV power grid. On this basis, the overall goal, the overall framework and the main modules of the integrated operation monitoring and fault co-processing application of the UHV interconnected power grid application function are proposed. Then, the related key technologies are analyzed and demonstrated, such as the operation status of the UHV power grid with the same monitoring of different dispatch centers, the coordination fault diagnosis of cross-regional power grid, the multi-level fault disposal joint implementation, fault information integration and multi-screen linkage display, ＂generation grid load＂ optimization coordination, provincial and prefectual power grid load coordination control and so on. Combined with the engineering practice in the relevant dispatch center of the UHV sending side and receiving side, the practical application effect is introduced. Finally, the future development directions and key technologies in the field of dispatching control of UHV power grid are discussed.
