Abstract

An improved system for a substation relaying and control wide area network based on a SONET or T carrier (Small Site) communication concept. In the WAN, every device (190-340, 410 and 480) at the substation or plant can be networked. This design concept offers many benefits including: every secondary signal, such as control, alarm, and indications signals, can be digitized; SCADA equipment can be interfaced or replaced in the WAN; metering equipment can be interfaced to the SONET protocol without actual secondary values at inputs to control house meter; panel device(s) footprint reducing the control housing dimensions; stub-up conduit quantity for the power equipment can be reduced thereby reducing labor and material costs; reliability and security can be increased; fault monitoring will be simplified; surveillance can be more practical; and site to site communication can be approached with leased satellite space as optional communications.
