Gateways are an important part in Substation Automation Systems (SAS).These are hardened communication devices which collect metering, status, events and fault report data from any protection device inside substation. The gateway sends this information upstream to a Control center, and transfers commands issued from the control center to devices inside the substation.
Heyuan’s intelligent gateway ASDU-LS perform the communication interface between the electrical substation and the area dispatch centers (SCADA) to transmit substation indications and measurements to SCADA, and dispatch SCADA’ commands to the substation control system. Also provides invaluable information for planning, management, maintenance and fault response via secure remote access.
