基于多Agent技术的自适应过电流保护的研究

传统的过电流保护的整定值是按离线最严重的情况进行的,而且在运行中基本保持不变,无法随电力系统变化而变化,因此该整定值在某些状态下并不是最佳的。在对传统过电流保护的缺点进行理论分析的基础上,提出了根据电力系统运行方式变化和故障状态的变化及配电网的其他变化而实时调节或修正过电流保护整定值的自适应过电流保护方案,并在部分过电流保护中安装方向元件。根据MAS具有自主性、社会性、适应性等特点,将多Agent技术应用于自适应过电流保护中去。建立了一个基于MAS的自适应过电流保护系统,通过各个Agent之间的协作,使得自适应过电流保护能够自动智能地适应电力系统的各种变化。

Research on adaptive overcurrent protection based on multi-agent

Traditional overcurrent protection settings are calculated in the worst condition and the settings will not change with power system operation mode.For the problems in the traditional overcurrent protection,the settings were not optimal in some conditions.Based on the theory analysis of traditional overcurrent protection disadvantage, this paper presents one new self - adapting overcurrent protection method to adjust the settings according to the different condition and fault and directional element is equipped in some overcurrent protection.A better adaptive overcurrent protection system is established with multi - agent system(MAS).With the merits of MAS,the adaptive over-current system can adapt the change of power system better.
