Integrated
Substation
Functions
In order to design an integrated substation, you must start by defining the jobs
that you wish the integrated substation system to perform. The list below
summarizes the most popular functional categories that integrated systems
perform:
➤ Remote status and measurement data collection and control
for SCADA. Collecting data from the IEDs and additional
inputs for display to operators through a SCADA system.
Coordinating controls from SCADA with local permissives.
➤ Local HMI (Human Machine Interface). Display of local
status and measurement and control often used for local
maintenance operation or backup local operation in the event of
a SCADA failure.
➤ Time synchronization. Synchronizing the time clocks of the
IEDs so that time referenced data can be compared between
IEDs.
➤ Distributed automation. Basic station automation and control
performed in IEDs rather than a central automation processing
platform like an RTU or PLC (Programmable Logic
Controller). This may also include dedicated control such as
capacitor bank control.
➤ Engineering and maintenance information management.
The collection, storage, and communication of historical, event,
and collected data that are used for fault analysis, maintenance
scheduling, system planning, and other engineering tasks. For
example, fault records and circuit breaker monitoring reports
are collected by protective relays and made available for
engineering through the system.
Integration With the SEL-2032
The SEL-2032 combined with SEL relays, non-SEL IEDs, and SEL software
solutions forms a comprehensive approach to substation integration. If we
consider the five basic functional categories listed in Integrated Substation
Functions on page 1.5 and construct a system out of conventional
components, we start with the system shown in Figure 1.3. In Figure 1.4 we
use a multidrop network to connect the IEDs to the RTU and provide basic
control and SCADA monitoring functions.
