常规变电站500 kV二次系统智能化改造方案的探讨

摘要

针对常规变电站500 kV二次系统智能化改造过程中面临的技术问题，引入中间转发智能设备实现不同二次系统之间的信息交互，对变电站500 kV二次系统智能化的改造方案与实施过程进行深入探讨，提出500 kV纵向改造调试方案和横向改造调试方案，通过分析各改造方案的特点和应用条件，提出了相应的建议。%In view of the technique problems in the intellectualized reconstruction of conventional substation 500 kV secondary system,mediating IED was introduced to realize information interchange between two different secondary systems. Modification program and implementing process of 500 kV secondary system reconstruction are profoundly discussed in this thesis. Based upon the analysis about the characteristics and application conditions of reconstruction schemes,some recommendations are presented.
