Protection of seawater heat exchanger on HVDC Converter Platform

All of the power generated by the wind turbines needs to be transmitted to shore and connected to the power grid. The Converter Platforms are the core piece of the offshore power generation and have the function of converting the power, generated by the connected wind  parks, from alternating current (AC) into high voltage direct current (DC). This is then transferred with low losses to the mainland using high-voltage direct current (HVDC) transmission.

The cooling of the converters and other systems on the platform is done using water from the sea. The plate heat exchangers used are the connection to the fresh cooling water system on the platforms. These heat exchangers will be protected by a water automatic filters like the aquaBoll®.

Reference of wind farm heat exchanger protection in the North Sea wind farm 

The converter platform BorWin beta located in the North Sea, is the core piece of the offshore power generation. The cooling of the converters and other systems on the platform is done using water from the North Sea. The plate heat exchangers used are the connection to the fresh cooling water system. Therefore wind farm heat exchanger protection was required.

The BOLLFILTER automatic type 6.18 filter prevents against blockage and a decreasing heat transfer from soiling. Since the platform operates without personnel and is controlled and checked from land, a 100% redundancy is required. Only in this way, a fault-free cooling of the converter is ensured, even in extreme weather conditions.

Since this commissioning, the filters have been working flawlessly, protecting the plate heat exchangers from blockage and thereby contributing to a smooth operation of the North Sea platform.
