Siemens SICAM A8000 Series Automation and remote terminal units

Siemens SICAM A8000 RTU series is a modular device range for telecontrol and automation applications in all areas of energy supply. This A8000 remote terminal units series was developed to fulfill the requirements of a broad field of applications. The most important features are: Suitable for rough ambient conditions thanks to mechanically stable modules and an extended temperature range from -40 to +70 degree C. High voltage strength up to 5kV (IEC 60255) for use directly in substations.

A8000 remote terminal units fulfill tomorrow’s cyber security requirements with BDEW White Paper conformity, integrated crypto chip and IPSec encryption. Integrated communications interfaces incl. GPRS on board. Automation functions (IEC 61131-3), e.g. for controlling a regulated distribution transformer or for load control. Space-saving design with a module width of 30mm (without display for CP) Scalable by combining individual I/O modules. Long product life cycle and high investment security by using standards as IEC 61850.

Siemens SICAM A8000 Series Applications

Precisely tailored to the application. Individual tasks and application scenarios require modules that can be freely combined in nearly any way. Thanks to the different performance levels of the processor modules and the universal expansion modules, the SICAM A8000 RTU series is nearly continuously scalable and can be expanded at any time.

• Simple gateway function

Power Quality

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.

Power Generation

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.

Grid Resilience

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.

Benefits:

• Platform modularity for versatile application options and reduced inventory.
• Extended temperature range of -40?C to +70?C for rough ambient conditions.
• Highest EMC stability up to 5 kV (IEC 60255).for direct use in substations.
• Integrated short-circuit indicator functionality for use in cable network monitoring.
• Use of international standards such as IEC 61850 for high investment security.
• Integrated crypto chip and IPSec encryption to fulfill the high cyber security requirements.
• Multitude of interfaces and integrated GPRS module for simple adaptation to existing communication infrastructures.
• Integrated web parameterization tool for simple engineering.
• Plug-and-Play functionality of the modules for time and cost savings.

The SICAM A8000 RTU series supports a smart 3-stage approach for grid optimization:

1. Monitoring: The first stage focuses on the monitoring of stations to enable rapid fault localization and high availability.
2. Telecontrol: The second stage involves switchgear telecontrol in addition to monitoring, thus minimizing downtime. Thanks to this application, fault isolation and power supply restoration of de-energized network sections are no longer difficult tasks for power supply utilities.
3. Load flow control: In the third stage, the effects of decentralized power feed-ins are managed via automation. Network losses can be significantly reduced this way.
