摘　　要：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。Interconnected power system needs powerful function to process different information for power system protection.Multi^information processing technology based on digital signal processing (DSP) is becoming a powerful tool and key link forprocessing complex protection information in interconnected power system. The power data language (PDL) and itsapplication procedure are presented. In addition, the paper analyzes the features of multiple complex protection information inInterconnected powel system, and sets up a multiple protection information database (MPIDB) system based on the complex.nonlinear and large^scale interconnected power system according to the basic rules of integrating protection and sharinginformation. The structure of MPIDB is also pointed out. Computer simulation results indicate that integrated protection withMPIDB has more powerful efficacy compared with traditional protection without MPIDB.This project is supported by National Natural Science Foundation of China (No. 79670012).
