变电站综合自动化系统测控装置设计

Design of the synthetic automatic system for Substation

针对我国电力事业的飞速发展和实时信息量的日益增多,本文提出多总线体系结构,上层(以太网)主要处理集控站内的人机操作界面,下层(现场总线)主要处理受控站内无人值守信息。用西门子S7-400型分布式控制系统建立了变电站综合自动化系统,其仿真结果表明,该系统具有快速响应和灵活调节的特性。

In this paper, according to the rapid developing of our power cause and increasing daily of the real time message, the multi-bus structure is proposed to coordinate supervise layer （internet） with supervisor layer （field-bus）. Supervise layer is to process the operator order and back field data in supervisor room, and supervisee layer is to control automatically the running-state in process devices. The result obtained from the system simulation with Siemens S7-400 demonstrates that the proposed system have quick respondent performance and flexible regulating feature.
