Example 4: Collect Unsolicited Write
(Synchrophasor) Data
The SEL-2032 is capable of collecting synchrophasor data from SEL IEDs
such as the SEL-311 series relays, most of the SEL-351 series relays, the
SEL-421 and SEL-451, and metering devices such as the SEL-734 at user-
defined discrete data rates. The SEL-2032 receives synchrophasor data as
Unsolicited Write (UW) Messages within the SEL Fast Message protocol.
This protocol is described in Section 9: Protocols.
Perform the following configuration steps to automatically collect
synchrophasor data as fast as 60 messages per minute from an SEL-311C and
make this data available to a DNP3 LAN/WAN master:
Step 1. Configure the SEL-311C Phasor Measurement Unit (PMU)
settings.
➢ Enter Access Level 2 on the SEL-311C and issue the
command SET G EPMU to edit Global settings.
➢ Configure the SEL-311C PMU settings as in Table 3 .6.
In this example, the SEL-311C is configured to transmit
all available synchrophasors to the Port 3 USER region
of the SEL-2032.
➢ Enter Y to save the global configuration changes at the
final prompt.
