Basler Electric and E Squared Power Systems have formed an alliance to provide complete turnkey power plant excitation retrofits. The companies will use the expertise of E2PSI’s engineering services and on-site project management experience and Basler Electric’s digital excitation systems, power system stabiliser and protective relays for power plants in need of upgrades. The two companies have collaborated on more than 200 digital excitation retrofit projects. Working together, E2PSI and Basler have designed direct standard retrofit packages for SCT-PPT and Alterrex voltage regulator systems. E2PSI can provide the up front system design interface/engineering, and technical direction for demolition and installation of equipment, startup, commissioning and training services using Basler Electric equipment. The turnkey retrofit solution gives the power plant owners the option of eliminating the rotary exciter and exciting the main field, which improves the reliability, reduces maintenance, improves efficiency and improves the generator performance and power system stability. Alternatively, the DECS-300 can be applied to the exciter shunt field of the rotating exciter. In either application the DECS system has increased features capability, improves controls, streamlines start up to minimise time to synchronise on line and provides communication capability through Modbus.
