Basler DECS-250 AVR retrofit awarded to EPS on a Solar Mars 100 following timely remote support

EPS have been awarded a contract for retrofitting obsolete AVR with a new Basler DECS-250 on Solar Mars 100. This is to replace an obsolete Basler DECS125-15 which was made obsolete by the manufacturer in 2013.

After encountering AVR issues, the customer contacted EPS to enquire about spares for their existing system. We had already completed Brush MAVR to Basler DECS250 AVR retrofits on another of their sites so suggested that this site made the same change.

The request was urgent as production was shutdown so EPS began work immediately. As part of this process, various areas were identified to the customer to check were working to assist with their immediate problem. EPS highlighted a particular relay to be checked which resolved the issue and got the customer up and running in short time. All of this being completed remotely whilst working on the engineering of the new retrofit. Through EPS’s attention to detail and focus to get the customer running, days of production were saved.

The customer still appreciated that the existing equipment was not supportable anymore so are continuing with the retrofit. The engine in question is a Solar Mars 100 11MWe which runs in conjunction with 2 x Rolls Royce/Siemens RB211’s.

This is just one of many retrofits EPS can perform. We have completed AVR retrofits not only on gas turbines, but also piston engine generators including Emergency Generators. These upgrades are completed with very little site intervention time to ensure that power stability is maintained.

Benefits of the Basler DECS-250

  • Reduce your setup time with Basler’s intuitive BESTCOMSPlus® software that simplifies complex setup with simple drag-and-drop programmable logic, visual real-time strip chart capabilities, and cutting edge auto PID selection capabilities.
  • The revolutionary auto-tuning function automatically establishes optimum PID and gain settings, taking the guesswork out of system setup, reducing commissioning time and cost while maximizing overall system performance.
  • Network Load Sharing provides easy implementation in complex paralleled systems.
  • The Offline Simulator in BESTlogic™Plus helps identify and troubleshoot the logic without the expensive need for physical hardware.
  • Powerful 15 amp pulse-width-modulated (PWM) power stage provides a high initial response for exceptional system response to load transients. Flexible PWM power stage makes it easily adaptable to any system – shunt, auxiliary winding, permanent magnet, or dc fed.
  • The DECS-250’s rms sensing and rugged power stage creates an easy, worry-free solution for applications containing high waveform distortion caused by non-linear loading.
  • The DECS-250’s advanced microprocessor-based design provides visionary expandability, flexibility, and reliable operation for any system.
  • The optional integrated power system stabilizer eases concerns about grid code compliance issues with its advanced power system performance and reliability, eliminating the need of external devices and wiring.
  • Contains a full suite of generator and motor protection for accurate fault detection and clearing, eliminating dangerous and damaging conditions to the generator or motor.
  • Multilingual user interface simplifies setting the DECS-250 and helps to eliminate potential errors in setup.
  • Contains an extensive array of communication options which allows for easy integration into a wide variety of control systems.
  • Grid Code: Component certified per standard VDE-AR-N 4110.
