EFFICIENT LINKING OF INDIVIDUAL WIND TURBINES OR WIND FARMS
There are two aspects to onshore wind power. Firstly medium voltage grids have to absorb fluctuating feed-in volumes from individual wind turbines. If the load is too high, voltage regulated distribution transformers stabilize the line voltage. Secondly there are huge wind farms with a capacity of up to one gigawatt and more, which have to be efficiently integrated into the grid. In the collector stations which link the turbines to form generator clusters, the tap-changers switch on a very frequent basis and over a wide voltage range to compensate for the fluctuating amounts of power. Many wind farms are also installed in locations highly sensitive to pollution. These need transformers which are hermetically sealed or which use environmentally-friendly and flame-retardant isolating fluids. What's more, wind power is often generated at great distances from most consumers. The existing grid infrastructure is subject to frequent switching operations, making high-voltage direct current (HVDC) transmission a real alternative.
RELIABLE TECHNOLOGY FOR MAXIMUM EFFICIENCY
REINHAUSEN helps you to efficiently link wind farms and individual wind turbines to the energy supply network. With our vacuum tap-changers,we enable 300,000 tap-change operations without maintenance – representing decades of smooth operation. Tap-changers are also available for transformers with alternative isolating fluids which are particularly environmentally-friendly and flame-retardant. VACUTAP® tap-changers are the best solution for hermetic transformers and are also suited to HVDC inverter-transformers, in both thyristor-based equipment and self-managed systems with bipolar, switchable power semiconductors. GRIDCON® Transformer, the voltage regulated distribution transformer, keeps the voltage stable in the distribution and medium-voltage grid. REINHAUSEN measurement technology helps you to assess the condition of the transformer as a basis for condition-based maintenance. Composite isolators from POWER COMPOSITES® satisfy the strict requirements in HVDC inverters. The excellent mechanical and electrical properties of our ROTAFIL composite materials have been proven over the years as generator couplings in wind turbines. And no matter where your wind farm is, our global service is available around the clock.
