Details are available on couple of recent optimisation projects below — we'll add to this periodically to offer a variety of live examples, working with different turbines and scenarios. If you'd like to know more about what we can offer, get in touch with the team at Reoptimize Systems for more details.

2% AEP
Challenge
This was our first pilot optimisation of a Siemens-2.3-93, and proved an excellent opportunity to implement our technology in a live environment. The turbine was noise-curtailed between the hours of 9 PM and 6 AM to reduce noise.
The aims of the pilot project were:
- Demonstrate a significant increase in AEP
- Demonstrate that Reoptimize Systems technology has no detrimental effects on the turbine and the machine stays within its load envelope
- Show that as a result of Reoptimize control settings there are fewer alarms and a reduced need for unscheduled maintenance
18%-25% (Dependent on AEP)
Outcome
Optimised control settings were first installed on the turbine in April 2021. Results of the Siemens turbine demonstrate:
1.5% Annual Energy Production (AEP) uplift
Reduction in tower loads of 25%
2% AEP uplift if loads are instead not reduced from baseline
1.5 dBA noise reduction (huge impact if noise curtailed)
Reduction in unscheduled shutdowns with causes such as rotor overspeed, bearing overheating, excessive vibration etc.
Elimination in current spikes at turbine startup by an order of magnitude

LOCATION: GERMANY
TURBINE: 2.3-93

6%
Challenge
Optimisation of a 60 kW direct-drive turbine. The ESPE FX23 has a larger rotor compared to peer designs, and this turbine had been downrated from 120kW to 60kW. The rotor speed had also been reduced by the OEM.
Key considerations:
The anemometer of the turbine was not properly calibrated
At this site the wind characteristics vary significantly depending on wind direction
Very strong turbulence, higher than on previously analysed machines
12%
Outcome
This machine was successfully optimised to produce an increase in Annual Energy Production of at least 6%, while simultaneously producing a much more stable power curve at higher speeds — remaining within vibration and load envelopes and reducing significantly the thermal stress in the electrical components.

TURBINE: ESPE FX23

5.2%
Challenge
Wind resource highly turbulent due to terrain roughness and tower height. This was causing extremely frequent vibrations that caused multiple unscheduled shutdowns.
The challenge was to aim for a maximum AEP subject to meet a minimum of 10% reduction of tower vibrations without decreasing output power significantly.
12%
Outcome
This machine was successfully optimised to produce an increase in Annual Energy Production of at least 5%, while simultaneously producing a much more stable power curve at higher speeds — remaining within vibration and load envelopes and significantly reducing thermal stress in the electrical components.

2022 White Paper
We recently published a white paper providing more details on our approach and a pilot optimisation project on a Siemens 2.3 MW turbine.
If you're interested to learn more about what we do for customers, this will provide a succinct overview for consideration.
