集成化变电站辅助系统的智能终端设计

由于集成化智能变电站的逐步应用推广,变电站运行的自动化水平日益提高。变电站辅助控制系统作为变电站的一部分,为变电站正常运行提供了必要的保障,其智能化水平也需要相应提高。文中针对变电站辅助系统的应用,设计了一种智能终端,通过对变电站开关量、模拟量的采集以及RS485、CAN总线的通讯实现了变电站温湿度、气体等运行状态的监控;通过开关量的输出或者RS485、CAN总线的通讯对现场空调、除湿机、灯光等设备进行控制;通过网络通讯实现信息的综合、上传及联动,实现了变电站的在线监测和可靠控制。

Intelligent terminal design of integrated substation auxiliary system

Due to the gradual application and promotion of integrated intelligent substations,the auto-mation level of substation operation is increasing.As a part of the substation,the substation auxiliary control system provides the necessary guarantee for the normal operation of the substation,and its intelligent level needs to be improved accordingly.In this paper,an intelligent terminal is designed for the application of substation auxiliary system.Through the monitoring of the switch quantity and analog quantity of the substation and the communication of RS485 and CAN bus,the monitoring of the operating temperature of the substation temperature,humidity and gas is realized.Through the output of the switch or RS485,CAN bus communication to control the on-site air conditioner,dehumidifier,lighting and other equipment.Through the network communication to achieve the integration,upload and linkage of information,the online monitoring and reliable control of the substation are realized.
