智能变电站二次设备的状态检监测技术研究

Study on the state inspection monitoring technology of the secondary equipment in intelligent substation

智能变电站分为过程层、间隔层、站控层。过程层包含由一次设备和智能组件构成的智能设备、合并单元和智能终端,完成变电站电能变换、传输及其测量、控制、保护、计量、状态监测等相关功能。智能变电站的二次设备是对一次设备进行监察、测量、控制、保护、调节的辅助设备。文章首先介绍了智能变电站二次设备的运用,提出了二次设备状态监测的必要性,探讨了计算机技术运用于二次设备监测和在线监测技术的推广运用。

Intelligent substation is divided into the process level,bay level and station level.The process layer contains a smart device composed by the primary equipment and intelligent components,merging unit and intelligent terminals,which completes the power conversion,transmission,measurement,control,protection,measurement,condition monitoring and other corresponding function of the substation.The secondary equipment in intelligent substation is a auxiliary device to monitor,measure,control,protect and adjust the primary equipment.This paper firstly introduces the application of the secondary equipment in intelligent substation,proposes the necessity of monitoring them,and discusses the computer technology be applied in the secondary equipment monitoring and the promotion and application of on-line monitoring technique.
