摘要
变电站中自动化设备的大量应用及电力设备自动化程度的提高,推动了变电站向智能化方向发展,提高了电网智能化控制水平。当前智能变电站实际运行过程中,继电保护技术方面存在一定不足,继电保护二次回路设计与传统变电站之间存在差异。根据智能220 kV输变电项目,构建了继电保护二次回路,提高了智能变电站中继电保护的适应性和智能变电站的运行稳定性,为智能变电站的设计奠定了理论依据。
The application of automation equipment in substation and the improvement of automation degree of power equipment promote the development of intelligent substation and improve the intelligent control level of power grid.In the actual operation process of intelligent substation,there are some deficiencies in relay protection technology,and there are differences between the secondary circuit design of relay protection and traditional substation.According to the intelligent 220 kV power transmission and transformation project,the secondary circuit of relay protection is constructed,which improves the adaptability of relay protection and the operation stability of intelligent substation,and improves the theoretical basis for the design of intelligent substation.
