Configure Ports – C37.118 Synchrophasor Protocol
Purpose and Background
The purpose of this section is to provide specific details of how to configure the 1133A to respond
correctly to C37.118 commands with synchrophasor data. PSCSV does not allow you to receive
or record actual C37.118 data. Use a specific “C37.118” application for that. PSCSV can view
C37.118-
type
phasor data, however certain elements are missing or added that support PSCSV
protocol that do not comply with the C37.118 specification.
7.8.1
Setup
To set up the 1133A to communicate using C37.118, you will need to configure the port being used
for C37.118, and set up some values used by C37.118. This will normally take two or three steps,
which are outlined below.
Basic Steps in Configuring C37.118 Synchrophasors
◦
Use PSCSV to configure the desired 1133A port for C37.118 protocol.
◦
Use PSCSV to configure PMU-1, PMU-2, or PMU-3 Ghost.
◦
Start your PDC application, or C37.118 software.
Details
1. Connect to the 1133A using PSCSV software with permission to configure.
2. From the left panel in the Configure Ports window, select the desired port with which you
wish to communicate – Communications Port 1, 2 or Ethernet. Select PMU-1, PMU-2 or
PMU-3 Ghost; under Protocol select either TCP or one of the UDP modes.
3. For example, under PMU-1 C37.118 Protocol, choose TCP, and if desired choose the port
number. Choosing one of the UDP modes provides additional settings (grayed out).
4. Next, you will need to configure each of the PMU’s. These are listed as PMU-1 C37.118,
PMU-2 C37.118 and PMU-3 C37.118 Ghost. PMU-1 and PMU-2 are separate but identical
in setup, however PMU-3 Ghost is really a pre-configured subset of Basic Data from PMU-1
or PMU-2. Data possibilities for Ghost PMU are explained on page 60.
7.8.2
PMU Setup Terms and Definitions
The definitions for the terms found in the PMU-1 and PMU-2 setup window are shown in
Figure 7.10. Open the window by selecting Connection
>
Configure
>
Communication Ports,
or by clicking the Configure Ports button and selecting PMU-1 or PMU-2.
Active
means that PMU-1 or PMU-2 is poised and ready to send data - set to ON if you want
it to be active. Set to OFF if you want it to be inactive (or unresponsive).
Station
(or STN) is the station name, in 16 bytes in ASCII format, given to either of the two
virtual PMUs. This field helps to identify the location of the equipment.
