Boost for power station

Sensonics has completed the retrofitting of two static digital excitation systems at Cruachan power station in Scotland.

Sensonics worked with Optimised Systems and Solutions (OSyS) to replicate the equipment fitted to unit 1 and unit 2 during previous works.

The new system was designed to offer high availability by using separate and diverse digital controller hardware in combination with dual thyristor bridges providing 100% full redundancy. These are all backed up by duplicate power supplies and independent protective trips.

A power system stabiliser was also included in the software algorithm to ensure Grid Code compliance.

For units 3 and 4, Sensonics provided the same OSyS equipment configuration which were fitted to units 1 and 2 in 2002.

Sensonics managed the entire project on a turnkey basis in terms of mechanical design, manufacture, factory testing and installation, through to commissioning the entire system in conjunction with the OSyS engineers.
