SICAM A8000 Series

The SICAM A8000 series is a modular device range for telecontrol and automation applications in all areas of energy supply. This device 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 °C. High voltage strength up to 5kV (IEC 60255) for use directly in substations. Fulfills 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. The SICAM A8000 series also offers the 3-stage smart functions: 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.

Applications

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 series is nearly continuously scalable and can be expanded at any time.

 

Example 1: High performance and many interfaces for complex tasks

  • Automation tasks in power distribution and transmission, micro-grids
  • Control functions in hydroelectric power stations, including the turbines themselves
  • Control and communication in railway power supply
  • As a communication gateway for various networks and protocols

Example 2: Everything in view with the compact solution on site

  • For use in distribution automation
  • Optimized for use in MV switchgear
  • Load-flow control available

Example 3: Space-saving design with no display and a slim CP module

  • Grid connection for solar and wind farms
  • Control and monitoring of electricity and gas distribution stations
  • 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.

Transparency

More data, increased transparency 

 

Modern electrical grid components deliver, process, and analyze data 

 

One consequence of digitalizing power grids is the steadily growing volume of captured data. These vast quantities of data harbor valuable information that describes the state of the grid, enables advanced computational analysis of changes, and can improve the performance and extend the service life of assets. The hardware and software from Siemens needed for this fulfills all the requirements.

CAPEX savings

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.

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.

OPEX savings

Optimizing business operations 

 

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

 

The growing demand for power from industries and households can be fulfilled simply. With modern technologies and innovative solutions such as optimized voltage and capacity management, self-healing grids, and by avoiding losses of any kind.

Microgrid Controller

SICAM Microgrid Controller 

 

Maximum security in operating microgrids 

 

Microgrids are a reliable alternative when autonomous power supply is needed, such as on islands, or when optimizations are required for higher level grids or supply costs. With grid-connected operation, microgrids enable energy to be reliably provided from renewable sources, at both high-peak and low-peak times. They can also influence reactive power and help save money by regulating the maximum power demand or infeed. Microgrids offer high reliability and improved energy quality. And they have a further advantage: Microgrids can operate independently of the higher-level grid.
