Growing challenges
The energy market is changing. The previously unidirectional power flows from the high voltage to the low voltage network have changed with the legally promoted and ever increasing decentralised generation and supply of energy. To ensure network stability, simple network monitoring is often no longer sufficient. As it is almost impossible to expand the networks at reasonable cost and time, they have to be adapted to the new challenges in a different way.
Intelligent supply networks as a way out
Modern telecontrol and substation automation technology allows intelligent supply networks to be set up. The combination of novel communication infrastructures with high safety standards means that effective and efficient network management can be realised. At the same time, expenses for commissioning and maintenance of a system should not be ignored, especially in times of growing cost pressure.
Makes efficient, tailor-made solutions possible: the series5
It is precisely here that it is the strength of the universal configuration tool SAE setIT, which allows intuitive, convenient and therefore fast configuration and commissioning of the systems. The Lacroix SAE hardware components of the series5 – FW-5, FW-50 and the FW-5000 – are in the same way optimally adapted to the requirements of the new focus on feed-in management and local network automation. These products together form a tried-and-tested, reliable basis for building high-quality, economical solutions which, most importantly, meet requirements.
Decentralized Energy Resources
The climate targets of the German government require considerable adjustments, not least in existing infrastructure. Depending on the respective plant output, decentralized energy resources (DER) operators must create the technical prerequisites for monitoring and controlling their plants. SAE provides efficient, configurable telecontrol solutions for this purpose.
Secondary Unit Substations
Distributed feed-in of renewable energy sources makes monitoring and automation of local network stations increasingly urgent. Firstly, to ensure stable networks with reliable voltage and frequency bands. Secondly, to avoid costly equipment overloading. SAE offers economical solutions which can be implemented within a short time.
Control Energy
Positive and negative control energy are used to secure the general power supply. This is procured by the large transmission system operators. In certain control areas, the operators of small regenerative plants are becoming increasingly important. Modern control technology enables them to be networked into virtual power plants with sufficiently high power potentials.
Protection Technology
Short cables, small impedances, high level of interlinking, multiple feeds – the protection of such structures while maintaining network stability is a challenge. The compact, modular combination protection device SG-50 offers a solution to this – with sophisticated protective functions and many different possibilities for use.
