电网调度自动化系统信息品质分析新方法及其应用
A new method of information quality analysis of power grid dispatching automation system and its application
摘要
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.关键词
