【摘要】 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。更多还原

【Abstract】 In order to make the stable control with hierarchy a nd distribution structure become most economical and effective, a double DS80C320 chip-microcomputers for data acquisition, GPS time service, software and hardwa re 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 ove r the network, to meet the requirement of stable control of large scale modern g rid.更多还原
