| 摘要: |
| 从功能配置、系统结构、内部数据的交互方式、与外部系统的协同模式、通信组网方案等多个角度进行研究，提出了包含站域层、区域电网层、广域电网层的多层次广域保护控制体系架构。针对不同层级电网关注的问题，提出了不同层级电网的保护控制功能配置方案。按照数据分类、分层处理的原则，给出了广域保护控制系统内各设备之间的数据交互方式，提出了广域保护控制系统与调度监控系统之间的交互模式。结合广域保护控制系统结构，给出了包括区域保护控制通信网络、广域保护控制通信网络的两层组网方案。所述广域保护控制体系架构中的区域保护控制系统已经 |

| Abstract: |
| The multi-level wide-area protection system scheme including substation level, regional-area level and wide-area level is proposed. Aiming to the different concerns, the protection & control schemes for the power grid in different levels are discussed. The data exchanged between the IEDs in the wide-area protection system is analyzed based on the system structure, and the collaborative mode between wide-area protection system and dispatch & monitoring system is also researched to optimize the protection & control schemes dynamically. The corresponding communication protocols are proposed for data exchange. In this system structure, the communication network for wide-area protection system is divided into several regional-area protection & control communication networks and wide-area protection & control communication network, which are distributed in two levels. The regional-area protection & control system is applied in Guangzhou power grid as one part of wide-area protection system, the feasibility and rationality of the technologies proposed are verified, which provides reference for the further research and application of the wide-area protection system. |
