Siemens SICAM FCG Gateway for short circuit indicators

The SICAM Fault Collector Gateway (FCG) device receives both the load current values and distribution line faults via the SICAM Fault Sensor Indicator (FSI). The device sends status data and event information to the control center using IEC 60870-5-104 or to the Siemens FLiC service via XMPP. The SICAM FSI device transmits detected fault information to the Siemens SICAM FCG Gateway using short-range radio (SRR) communication over distances up to 100 meters.

SICAM FCG provides 6 binary inputs and 3 binary outputs. The system allows users to configure and diagnose SICAM FCG locally through a Web GUI connection on a PC or laptop, or remotely using GPRS. The device features a plastic enclosure, and engineers recommend installing the SICAM FCG within a metal cabinet to enhance protection. The Global System for Mobile Communications (GSM) and short-range radio antenna are mounted outside the metallic cabinet. SICAM FSI firmware and parameters can be updated from the SICAM FCG. SICAM FCG Web GUI allows you to configure the parameters, display error and event log, upgrade of firmware, and download the configuration.

Functions

Binary interfaces

• On the terminal block L, all the 3 binary inputs are independent and have a fixed threshold of 8 V. On the terminal block P, 2 binary inputs have a common root (P8, P9, and P10), 1 binary input (P11, P12) is independent.
  These binary inputs have selectable thresholds of DC 19 V, DC 88 V, or DC 176 V.
  Therefore an optimal adjustment to the pickup voltage can be made in the case of increased interference level.
  The binary outputs are designed as relay contacts. The terminal block P has 2 relay outputs Normally open (NO) and one relay output change over (CO). The relays can switch voltages up to AC/DC 250 V and currents up to AC/DC 5 A.

Communication

• SICAM FCG is a gateway device on the communication network between the SICAM FSIs and the control center. It provides interfaces and supports communication protocols to the SICAM FSIs (via short-range radio) and to the control center (via mobile networks). The gateway contains an interworking function for the communication exchanged between SICAM FSIs and the control center.
  The various device communication interfaces and protocols are available for the communication between the SICAM FCG and the control center.
  SICAM FCG has an Ethernet interface which supports the device parameterization and the monitoring.
  The communication interface supports the device parameterization and the transmission of messages and measured values. The system securely transmits information in telegrams.

GSM module

• The module supports 4 frequency bands: 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz.
  The system communicates with the control center using IEC 60870-5-104 over an IPSec tunnel via GSM.You can execute the configuration and local diagnostic remotely via GSM. The communication to the Siemens FLiC service is based on XMPP and GSM.

Short-range radio module

• The short-range radio module communicates directly with SICAM FSI via a radio link in the license-free 2400-MHz band and up to 100 meters. The SICAM FSI device transmits overhead distribution line faults and status changes to SICAM FCG using the short-range radio module

Time synchronization

In operation, the device needs the date and time for all time-relevant processes. This ensures a uniform time basis and a time stamp for the communication with peripheral devices. The device executes the following time synchronization methods according to the defined parameter settings:

• External time synchronization via Network Time Protocol (NTP) (recommended, see 7.3.1 time synchronization).
• Internal time synchronization via Real-Time Clock (RTC) (if there is no external time synchronization).

Siemens SICAM FCG Gateway Applications

Unplanned outages

Keeping your grids up and running 

Using sophisticated tools and solutions for fast grid restoration

Unplanned outages cannot always be avoided. Flexible solutions for local and remote monitoring enable the fast and efficient restoration of cable grids and overhead lines.

Operational savings

Optimizing business operations 

Comprehensive and efficient ways for municipalities and DSOs to get the most out of their efforts.

Utilities can efficiently meet the growing power demand from industries and households. With modern technologies and innovative solutions such as optimized voltage and capacity management, self-healing grids, and by avoiding losses of any kind.

Fault localization

Fault reporting – fast, flexible, and direct 

The Fault localization in the cloud – the cloud-based service for fault detection by Siemens

Control room systems previously formed the basis for fast and efficient fault management. Fault localization in the cloud is a new, cloud-based service, which makes it possible to send fault information – including the fault location – directly to the maintenance crews, without the need for a grid control center.

Today power system operation is becoming more and more dynamic – which requires flexible, tailored solutions for reliable operation and efficient project management. The comprehensive SICAM portfolio offers network operators and utilities everything they need for future-proof substation automation – anywhere in the world. To explore the SICAM portfolio Click Here!
