Introduction
We supply new Control systems for existing LW15/75 and LW18/80 control cabinets.
Our WES80 Control cabinets are supplied with two IGBT back-to-back AC/DC/AC converters. The three- phase alternating current produced by the generator is transformed to a direct current (AC/DC conversion). This direct current is then converted back into an alternating current (DC/AC conversion). The last AC/DC conversion generates an AC current that fits perfectly into the public electricity grid.
Benefits of a new control cabinet
- Lower flicker values, making it easier to supply power into the power grid.
- Will drive the turbine better when the turbine has difficulties to start-up when the gearbox and generator are cold.
- Supplies the turbine with an electric braking system.
- Supplies the turbine with remote monitoring system via internet – PC and/or smart phone.
- Guaranteed availability of spare parts and components.
- Guarantees a higher production.
