This document discusses solutions from Siemens for monitoring and improving power distribution networks. It summarizes Siemens' offerings for network monitoring, power quality recording, and fault detection. It then describes the SICAM FCM product which monitors distribution network components to provide accurate data on network conditions. It lists the benefits of SICAM FCM such as fault localization, selective fault information, reduced restoration times, and reliable measurement values for operation management and planning.

1. Siemens

2. More transparency in the distribution Network
The key to continuously improving power supply is essentially in depth
knowledge of the relevant conditions of the local network. This is achieved
through the use of all available sources connected to the system.
Siemens offers a complete portfolio for network monitoring, power quality
recording, fault recording, phasor measurement and system software
application.
Power quality and measurements supports power supply utilities and
consumers with solutions required for the precise measurement, recording
and reporting of the necessary distribution network data used to
continuously determine, adapt and improve the power quality.
Description

3. SICAM FCM the finger on the pulse of your distribution Network
SICAM FCM (Feeder Condition Monitor) is a short circuit and ground fault
indicator with direction indication which uses protection algorithms and latest
low power sensor technology according to IEC 60044, yielding top results,
particularly in isolated or compensated distribution networks.
SICAM FCM offers comprehensive measured values to monitor the load of
distribution network components thus providing accurate data on the network
condition. Live values, e.g. of a transformer operated at overload, allow
countermeasures to be taken in time such as load shedding or reducing the
feedback power in the affected network segment.
In order to correctly evaluate the condition of the distribution network,
SICAM FCM provides all relevant data via a Modbus RTU interface.

9. Ensuring power quality in a phase of energy transition
Increasing power feed-in from renewable resources poses new challenges for
municipalities and distribution system operators
The stable supply of electric power is any grid operator’s top priority. To avoid
fluctuations in power quality and prevent disturbances, grid monitoring, control, and
automation systems need to be adapted and optimized across all voltage levels.
Maintaining control of distributed power producers
Ensuring grid stability is becoming increasingly complex
The vast number of small distributed power producers calls for new strategies to
ensure consistent power quality. Identifying, locating, and eliminating disturbances
and faults as well as the flexible, quick balancing of power production and load
consumption require integrated hardware and software solutions that work smoothly
together.
Application

10. Intelligent technologies for stable grids
Automation solutions and remote control technology enhance the reliability of
distribution grids
Despite every effort, grid disturbances and faults can never be entirely eliminated.
This is why control room personnel must be enabled to work quickly and effectively
to resolve problems in a targeted manner. Comprehensive automation and remote-
control solutions optimize these capabilities.
Efficient grid expansion
A combination of robust technology and digital innovations leads to increased
efficiency
Maintaining or even increasing grid performance is becoming ever more challenging.
With growing efforts, expenses grow as well. Innovative technologies and smart data
usage can help municipalities and DSOs to master these challenges and to increase
their competitiveness.
