变电站电气二次系统的设计分析

Design and Analysis on Electrical Second System of Substation

电气二次系统的设计、布置方案直接关系到整个变电站运行的稳定性和可靠性,本论文通过对变电站主结线的电气设计计算,着重讨论了变电站的电气二次系统的控制方式、以及与一次设备的连接等环节,并给出了详细了优化设计方案供实现变电站的二次系统的自动化设计参考使用,对于提高变电站电气系统的安全性及自动化水平有一定借鉴意义。

The design scheme and distribution scheme of electrical second system has influence on the whole substation＇ s stability and reliability. This paper calculated the electricity of main node line of substation firstly, discussed the control mode, connection link and so on of the electrical second system, and then the optimized design scheme was also pointed out for the automatic design. All this work is significative for enhancing the safety and automation of electrical system in substation.
