分布式稳控装置中前置机的设计与实现

Design and Implementation of Front-End Computer System in Distributed Stability Control Device

为实现最为经济有效的分层分布式稳定控制方式,以华中电网为例在前置机采用双 DS80C320 单片机数据采集、GPS授时和软硬件纠错等技术,使其具有多路同步采集、快速并行数据交换和全网采样时间同步等特点,能满足现代大规模电网的稳定控制要求。

In order to make the stable control with hierarchy and distribution structure become most economical and effective, a double DS80C320 chip-microcomputers for data acquisition, GPS time service, software and hardware error correction and so on are utilized in front-end computer system, which actually applied in Central China power grid. It makes the system with multipath synchro acquisition, fast concurrent data exchange and synchronous time all over the network, to meet the requirement of stable control of large scale modern grid.
