基于多代理技术的智能电网继电保护在线整定系统

Protective relaying on-line coordination and calculation system of smart grid based on MAS

基于多代理技术,研究并设计了智能电网继电保护在线整定系统。该系统按分层分区模式设计,充分利用多代理的智能化特点和并行计算优势,实现了定值的在线整定和在线更新,提高了保护性能。并通过使用阻抗矩阵确定定值修改范围、使用基础定值和预整定定值、使用GPS统一定值更新时间及代理自检等方法,保证了系统具有良好的实时性、同步性和抗故障能力。

Based on the MAS, this paper studies and designs the protective relaying on-line coordination and calculation system of smart grid. The system, which is designed based on the layering partitioning, makes full use of the intellectualized characteristic of MAS and advantages of parallel computation, achieves the on-line setting calculation and setting updating and improves the protective value. It adopts the methods of fixing on the setting modification range by the node impedance matrix, applying the basic setting and pre-setting, applying the GPS to unite the updated time, and doing the agent self-criticism, which make sure the system has a good real-time, synchronization and anti-failure capacity.
