Figure 4. Tap changer control and power transformer thermal overload protection using REU615 with the standard configuration B
Figure 4 illustrates tap changer control and power transformer
thermal overload protection using REU615 with the standard
configuration B. The tap changer position information is
received as a mA signal from the tap changer operation
mechanism. The position value is sent to the transformer
differential protection function of RET615 using GOOSE
messaging. The analog GOOSE messaging enables the tap
changer control of the two parallel running power transformers.
The RTD inputs complement the thermal overload protection by
measuring the oil and ambient temperature of the power
transformer.
5. Supported ABB solutions
The 615 series protection relays together with the Substation
Management Unit COM600S constitute a genuine IEC 61850
solution for reliable power distribution in utility and industrial
power systems. To facilitate the system engineering, ABB's
relays are supplied with connectivity packages. The
connectivity packages include a compilation of software and
relay-specific information, including single-line diagram
templates and a full relay data model. The data model includes
event and parameter lists. With the connectivity packages, the
relays can be readily configured using PCM600 and integrated
with COM600S or the network control and management
system MicroSCADA Pro.
The 615 series relays offer native support for IEC 61850 Edition
2 also including binary and analog horizontal GOOSE
messaging. In addition, process bus with the sending of
sampled values of analog currents and voltages and the
receiving of sampled values of voltages is supported.
Compared to traditional hard-wired, inter-device signaling,
peer-to-peer communication over a switched Ethernet LAN
offers an advanced and versatile platform for power system
protection. Among the distinctive features of the protection
system approach, enabled by the full implementation of the IEC
61850 substation automation standard, are fast
communication capability, continuous supervision of the
protection and communication system's integrity, and an
inherent flexibility regarding reconfiguration and upgrades.This
