微机网络型全自动电站监控系统的结构及其控制原理

本文介绍一种舰船用微机网络型全自动电站监控系统的自动控制原理及方法,该系统实现了不同种类电源供电自动联锁;船电和岸电不断电自动切换;有故障机组或过载时,备用机组自动投入和报警;轻载时,备用机组自动停机;同时还可在配电控制室遥控机组自动起动投入或自动解列停机;另外,还实现了各机组热工参数越限声光报警及大负荷设备起动询问联锁功能;最后,依据系统的结构特点,说明系统是如何采取措施提高其可靠性。

The Structure And Control Principle of Microcomputer Network Type Monitor/Control System of Complete Automatic Power Plant

In this paper the control principle and method of a marine microcomputer network type monitor/control system of complete automatic power plant have been described. The system can carry out the automatic interlock of different kinds of power suppllies and automatic non-blackout cut-over of electricity between ship and shore. Whenever any generator set fails of overloading, the standby set starts up and switches on automatically, and the system alarms. While on light load the standby set shuts down automatically. The operations of start-up, switch-on, release and shut-down could also be remotely controlled in distribution control room, The functions of parameter measurement, visual and audible alarm on over-limit and inquiring interlock on high-power load starting are achieved. Finally, the measures for improving system reliability depending on the structural features are illustrated.
