为适应智能电网的建设需要,对非综合自动化变电站建设建议全部改造成IEC61850规约变电站.变电站自动化系统只在站控层和间隔层实现基于IEC61850标准的系统;监控装置、远动装置、继保子站、测控装置、电压切换装置和低压裳置全部按新建变电站配置.自动化系统的站控层采用双以太网,采用IEC61850规约;保护通信予站采用单以太网,IEC61850规约;低压保护设备、测控装置、新上高/中压保护设备采用IEC61850规约,通过双网将数据上送监控装置.未改造的采用RS-485或以太网103通信的保护设备,由各制造厂家负责升级改造.根据目前非综自站的现状,指出应考虑改造顺序、网络设备、增加交/直流馈线柜等方面问题.

It is suggested to retrofit the non-integrated automation substation based on IEC61850 to meet the needs of smart grid construction. Only the station level and bay level of substation automation system adopt IEC6185O standard and the devices of monitoring,remote control,protective substation,measuring & control,bus-switchover and low-voltage protection are configured as new substation. The station level applies dual Ethernet based on IEC61850 protocol; the protection substation applies single Ethernet based on IEC61850 protocol; the low-voltage protection, measuring & control device, newly-configured high /medium -voltage protection sends data to monitoring devices via dual net based on IEC61850 protocol;the reserved protective equipments applying RS-485 or Ethernet 103 communication are upgraded by the manufacturers. According to the current status of non-integrated automation substations, it is pointed out that the retrofitting sequence, network equipment, increased AC/DC feeder cabinets and so on should be taken into account.
