概述了电网数据语言 ,同时分析了互联电网中多元保护信息的特征 ;面对复杂的非线性的大规模互联电网 ,电力系统保护的任务日益艰巨 ,因此实现多种继电保护集成与集中处理、共享各类信息是建立多元保护信息数据库的重要依据。文中研究了互联电网中基于数字信号处理 ( DSP)的多元保护信息数据库 ( MPIDB)的设计过程 ,并建立了相应的结构体系。计算机仿真表明在互联电网中使用 MPIDB,其效能、效率和效益均比传统保护好
In the face of complex non-linear large-scale interconnected power grids, the task of power system protection is becoming more and more arduous. Therefore, a variety of relay protection integration and centralized processing are realized, Sharing various types of information is an important basis for establishing a multi-factor protection information database. In this paper, the design process of MPIDB based on Digital Signal Processing (DSP) in interconnected power grid is studied and a corresponding structural system is established. Computer simulations show that using MPIDB in interconnected power grids is more efficient, effective and effective than traditional protection
