China‘s smart grid: Making the energy of the future possible today.
Future power grids will have information and communication capabilities which will enable them to meet the demand for electricity more efficiently, more reliably and more flexibly. As the biggest power consumer in the world, China is investing massively in the transformation of its grid into a modern smart grid – and in doing so relies on our thermal management technology for electrical enclosures.
Moving forward – with Pfannenberg solutions.
Huge ultra-high voltage transmission routes transmit the wind energy from the North West and water energy from Central China to the mega cities on the country’s coast. Digital transformer stations play a vital role in the development of the intelligent transport network. Their gas-insulated switching systems, voltage and current converters are fitted with smart electrical enclosures which contain components for communicating with the control centre, amongst other features. The fittings for these electrical enclosures include specially developed cooling units from Pfannenberg.
Smart electrical enclosures – smart thermal management.
Specially equipped type DTI 8161 cooling units are responsible for providing thermal management for the electric components in the smart electrical enclosures. To enable them to be integrated into the communication system of the control centre, they have an intelligent control system and an RS 485 interface for serial high-speed data transfer. Integrated self-diagnosis minimises the need for maintenance, which the unit communicates to the centre if necessary. Long air ducting enables a perfect airflow through the electrical enclosure and eliminates hot spots. The robust cooling units are supplied in stainless steel housing and, thanks to a condenser with especially wide fin spacing, deliver highly effective protection against severely contaminated and aggressive ambient air. Since the smart electrical enclosures are generally located outdoors and are exposed to temperature and weather fluctuations, the cooling units have integrated heating. This means that the interior of the electrical enclosure can be protected against corrosion, even in winter and in a humid climate and that temperature can be maintained continuously at a level ideal for the electronic components.
Maximum control centre availability.
The digital transformer stations in the expanding smart grid in China are equipped with communication- enabled control centres. These are supplied in the form of fully equipped containers. The cooling of its sophisticated electronics is done by powerful outdoor-proof cooling units with the respective communications interfaces.
The internet of energy.
Creating intelligent, communication-enabled and flexible power grids is regarded as one of the greatest technical challenges of our time. As a leading company in the field of industrial thermal management, we offer solutions for that already today. Across the world, we support the development of smart grids with our innovations – on the way to a global internet of energy.
