面向智能电网的变电站状态监测系统改造研究

为应对我国“十二五”期间大规模变电站智能改造，以及相应产生的传统变电站状态监测系统的智能化改造需求，文章以500kV传统变电站为例，从系统结构、主通信网络、通信标准、站控层及间隔层软硬件、诊断方法等方面进行分析，给出了升级改造的实现方法，指出下一步研究方向。该改造能为实现智能电网的信息化、自动化和互动化奠定良好的基础。

Research on Transformation of Substation Condition Monitoring System of Smart Grid

To meet the needs of intelligent transformation of the traditional substation condition monitoring system during the 12th five-year plan period of China, taking the traditional 500 kV substation for an example, this paper analyzes the existing substation condition monitoring system from aspects of system architecture, main communication network, communication standard, hardware and software of process level and bay level, and fusion diagnosis methods. And then an implementation of the transformation is given and the future research direction is put forward. The transformation will be helpful to lay a good foundation for achieving informatization, automation and interaction of smart grid.
