摘要: |
电网调度自动化信息交互涵盖变电站过程层、间隔层、站控层、变电站与调控主站之间、主站与主站之间等环节,各环节不同应用间的信息通信标准具有各自的信息品质码。完整地解读了IEC系列标准与国内电力行业标准关于信息品质的规定。从调控数据交互信息品质应用角度考虑,介绍了IEC 62361-2标准内容,梳理了IEC系列标准(IEC61850、IEC60870-5-104、IEC60870-6、IEC61970等)及国内电力行业标准(DL476)关于信息品质码的基本原理。结合智能电网调度控制系统对基础数据的应用,提出了数据交互合成信息品质处理原则,详细分析了调控数据交互过程中不同通信规约之间信息品质映射规则。最后基于信息品质应用创新性地提出了一种基于取代服务的调控信息验收核对方法。 |

Abstract: |
Information interaction of power dispatching automation covers the process level, the bay level, the station level, the loop between the substation and the main control station, loop between two main stations, etc. The information communication standard of each section of different applications has its own quality code. It perfectly interprets the IEC series of standards and the domestic power industry standards on the code of information quality. It analyzes the basic principles of IEC series standard (IEC 61850, IEC60870-5-104, IEC60870-6, IEC 61970, etc.) based on IEC 62361-2 and domestic electric power industry standard (DL476) on information quality code from the perspective of interactive information quality of control data. Based on the application of basic data by intelligent power grid dispatch and control system, the principle of data interactive compound information quality processing is put forward. The rules of information quality mapping between different communication protocols in interactive process of control data are analyzed in detail. Finally, based on the application of information quality, a new method of checking the information is proposed based on the substitution of service. This work is supported by Science and Technology Project of State Grid Corporation of China “Research and Application for Wide-area Operation and Maintenance Techniques of Substation Automatic Equipment”. |
