Principle of safety of the wind turbine
When building a wind farm, the issue of network connection delays is a critical point. The creation of a delivery station by the manufacturer is not always simultaneous to the connection to the source station of the network or even to its construction. Therefore, putting a wind turbine into “hibernation” can present a risk for equipment. Without voltage or heat, condensation develops in the mast and can impair the proper functioning of electrical equipment.
It is therefore appropriate to couple the wind turbine to a generator to power the auxiliaries. The testing of these auxiliaries is then possible or even recommended (mandatory in Spain, Germany and the countries of Northern Europe) before connection. The load bank simulates a load (at least 30% of the capacity of the turbine) and avoids the problems of premature wear on the one hand and on the other hand to test the different equipment.
The types of wind load bench applications
- Load bank to test the wind turbine in charge and validate the protocol before connection (emergency stop, etc.)
- Load bench to simulate the generator of the wind turbine
- “Test type” bench for factory testing of new wind turbine models
