Remote Terminal Unit for MV/LV substation –UP2020 Lite
GSTR002
Rev. 02

4 INTRODUCTION
160
The UP2020 Lite equipment is an enhanced version of the RTU, consisting of all the functionalities and
161
hardware requirements of UP 2015 Global RTU, but integrated with furter software functionalities, detailed
162
in this specification document.
163
For this reason the UP2020 Lite specification (GSTR002) is based on the UP2015 specification
164
(GSTR001/1, rev.1) and most of its technical attachments continues to apply to UP2020 Lite.
165
Enel standardized MV remote control solution include a Remote Terminal Unit (RTU) and, optionally, as
166
many fault detectors as the Line Out switches.
167
The components and elements of a MV/LV substation that can be remote controlled include MV and LV
168
switch-disconnectors and circuit breakers. The Global Standard GSTR002 describe the standardized
169
Remote Terminal Unit (RTU), also called UP, which can be used to remote control MV/LV substations, or
170
to remote control pole mounted motorized switches. The UP is also the devices responsible to execute
171
the self-healing distributed automation, when coupled with standardized fault detectors.
172
The central Remote Control System (Center, in the remainder) of the medium voltage distribution network
173
is composed of:
174
a Central Unit;
175
a Front-end for communication with peripheral devices;
176
Working Stations;
177
etc.
178
The central unit is intended to perform the following functions:
179
validation and transmission of the commands given by the operator to the Remote Terminal Units
180
(RTU);
181
acquisition, processing, and storage of data coming from the RTUs;
182
selection of the faulty branches;
183
configuration and remote diagnostics of the RTUs;
184
Synchronization of the clocks of the RTUs.
185
This document describes the functions of the RTU devoted to medium voltage distribution network, and
186
provides, nonetheless, the construction requirements for the provision.
187
The Center is capable to use all of the communication systems available on the market (public switched
188
telephone networks, mobile networks, etc.), or those which can be implemented ad hoc (dedicated radio
189
networks), which ensure messages transit times compatible with the System requirements.
190
The RTUs are expected to carry out the following functions:
191
To communicate with the central system and ensure the forwarding to the field device of the
192
remote controls received by the Center. A field device can be:
193
oMedium Voltage Switch Disconnectors (SD), located in Secondary Substations or pole
194
mounted
195
oMedium Voltage Circuit-Breakers located in Secondary Substations or (SSCB) or pole
196
mounted
197
oReclosers
198
oLow Voltage motor-driven Circuit Breakers (LVCB) in the secondary substations
199
(switchgears in their general acceptation);
200
To detect the status of the switchgears and the diagnostics of each RTU, and make them available
201
to the Center;
202
To detect the fault signal from the fault passage indicators or protections (RGDAT/RGDM) that
203
are installed in correspondence of the switches to be monitored, and subsequently store them with
204
the date/time of occurrence, in order to make them available to the Central Unit;
205
To implement automatic procedures for the selection of the faulty branches;
206
To record field measurements (indoor temperature of the substation, currents, etc.), and make
207
them available to the Center.

The RTUs can also be used as a part of MV/MV switching substations, where they remotely control the
209
circuit breakers, and record the signals and measurements from the related protection and control panels.

Nonetheless, it has also to be possible the remote download of the firmware for one or more UE
337
(management of lists of devices). This operation may be executed either by the Center, by means of the
338
same communication devices normally used for the remote control, or from a standard PC with a modem
339
or LAN. For this purpose, a suitable software module must be provided, to be installed on a PC.
340
341
5.2.8 Functionalities based on MQTT protocol
342
UP2020 Lite must implement an MQTT Client and an MQTT Broker services. These services will be used
343
to realize a peer-to-peer automation named “DBR”, and for publishing information (statuses and measures)
344
from IoT sensors acquired by TCP ModBus.
345
While utilizing an istance of MQTT Client functionality, it will be necessary to configure at least the following
346
parameters:
347
oBroker IP Address (MQTT Server where to publish messages)
348
oMQTT or MQTT over SSL mode
349
oMQTT TCP Port to be addresses (Default MQTT = 1883, Default MQTT over SSL = 8883)
350
351
352
5.2.8.1. DBR Automation
353
UP2020 Lite must implement a new automation based on the exchange of communication between RTUs.
354
The principle of this automation is described in the attachment “Automazione DBR - DSR per UP”.
355
Any UP participating to DBR is configured with at least the IP ADDRESS of the next UP (from the
356
topological point of view) installed on the MV network, and the IP ADDRESS of the UP installed on the
357
border of the feeder. DBR allows, thanks to the communication between UPs to manage remote open and
358
remote close of other breakers, managed from remote UP.
359
The automation is fully described by the automatons specification DX1220 ed.11 (latest revision). Some
360
of the states are the trigger condition in order to publish messages to the “Next UP” or to the “Border UP”
361
using MQTT protocol. The procedures reqested at the subscription of a message is described in DX1220
362
ed.11 (latest revision) as well.
363
364
5.2.8.2. Galileo Functionality
365
UP2020 Lite must implement an application gateway for transmission to a specified central system
366
(Server/Broker different from the SCADA system), of information collected by a series of sensors installed
367
in the substation.
368
UP2020 Lite will acquire the information from the sensors by adopting TCP ModBus interface, this interface
369
can be configured via a json file imported into the software.
370
UP2020 Lite will collect such information, store it locally (circular memory with the latest 500 messages),
371
and publish it by adopting a particular topic to the configured MQTT Broker, adopting JSON payloads as
372
exemplified below (real examples of messages recognized and accepted by the MQTT server for the
373
GALILEO application):

5.3.4 Power supply
535
The UE is supplied by a 24V -15%, + 20% PSBC, which is described in Chapter 6.
536
The UE must be immunized against transient reductions of the supply voltage from 24V to 12V, for a
537
100ms time interval.
538
The UE must provide with a protection against the reverse polarity of the power supply wires.
539
The UE delivers the 24VDC power supply (by means of the pins +M and -M of the 12 socket connectors,
540
see Figure 7) to all of the switchgears in connection with it. The internal conductors of the UE (either cables
541
or patterns of the printed circuit boards), related to the power supply of the motors, must be of equivalent
542
section not less than 2mm2.
543
