摘要 坚强智能电网建设要求继电保护提高自身性能的同时,也需要加强与安稳控制的优化协调。提出面向区域电网安全稳定的层次化保护控制系统的概念,该系统在传统保护配置的基础上,设置基于信息共享的站域保护控制和广域保护控制。介绍了层次化保护控制系统的架构及功能配置,对比分析了其与现有保护、广域保护的性能,给出应用功能示例。研究结果表明,所提出的层次化保护控制系统可作为今后智能变电站建设的应用方案推广实施。 A strong smart grid requires relay protection not only to improve its performance, but enhance the optimization and coordination with stability control system as well. A new concept of hierarchical protection &control system oriented to regional grid security and stability was proposed. On the basis of conventional protection configuration, the substation-area protection & control unit and wide-area protection & control unit based on information sharing were set up. Then, the framework and function deployment of hierarchical protection & control system, as well as its application examples were introduced. Through the comparison with the existed protection scheme and wide-area protection scheme, its performance was also analyzed. The results have shown that the proposed hierarchical protection & control system can be promoted and applied in smart substation construction as application scheme.
