Retrofit your Vestas* turbine COTAS controller. Optimise availability and increase your AEP
Retrofit Vestas* V25, V27, V29, V39, V42, V44, V47
Retrofit your Vestas* turbine's COTAS controller and optimize availability that will improve your annual energy generation, reduce service cost and extend the lifetime of your turbine.
Optimize turbine availability
DEIF Wind Power Technology offers a cost-effective solution to retrofit older Vestas* turbines. The solution focuses on solving the problem of down-time of the COTAS controller by replacing it with new system securing a higher level of turbine uptime reusing the same interface. The advantage with a retrofitted controller solution by DEIF Wind Power Technology, is that Vestas* or Gamesa turbines achieve optimized availability and improved production, which gives a total lifetime extension.
Retrofit and avoid investing in old Vestas* spare parts
With DEIF Wind Power Technology’s retrofit solution your turbine gets upgraded with a completely new controller, and this resolves your problem for searching the missing spare parts on the market. DEIF gives 5 years warranty and a minimum of 20 years delivery time for spare parts. Your costs will be reduced and you can avoid investing in additional expensive Vestas* spare parts in the future.
Improve SCADA access
Another solution to optimize your investment is to improve the monitoring and surveillance of Vestas* turbines. A retrofitted control system from DEIF Wind Power Technology will provide you with new possibilities such as:
- Centralized monitoring for surveillance of production
- Turbine income
- Local service surveillance for monitoring turbine condition for taking proactive actions in terms of scheduled maintenance
Independent power producers (IPP) and turbine owners will get full access to all relevant production and surveillance information through either a DEIF SCADA system or as interface to existing SCADA systems. This solution can be customized to individual needs as well as to comply with new regulations.
Reuse graphical interface in retrofitted turbine
DEIF Wind Power Technology has a long history in the wind segment and is experienced with providing service for existing and retrofitted turbines with focus on making the solutions easy to handle.
DEIF ensures e.g. that displays like the CT 218 used with the VMP 3500 controller can be reused in the retrofitted Vestas* turbine, securing that service and maintenance will continue uninterrupted with same usage and routines as normal. Retrofit can be done in just a few hours ensuring that minimum of two turbines per day can be retrofitted. And, this includes a customized education and training program.
Reusing the same interface in your retrofitted turbine is a key to achieve both an optimized retrofitted Vestas* turbine and at the same time to keep the transition cost in terms of usage and maintenance as low as possible. A complete new state-of-the-art touch panel based HMI solution can also be established by request.
Approval and certification
DEIF Wind Power Technology is the only worldwide approved alternative for COTAS controller in Vestas* V27 and V47 turbines from this generation. With this experience, we are an ideal supplier to retrofit older turbines.
Certification and approval of the retrofitted Vestas* turbine can be different from each country or region. Upon requirement by local authorities, DEIF Wind Power Technology can assist in the approval process and will be your partner in carrying out the relevant tests and approvals together with the certifying body. DEIF Wind Power Technology collaborates together with design houses for load calculations and approvals.
DEIF has a worldwide service organization that can support locally with spare parts and participate in the training of service engineers.
Retrofit of COTAS VMP 3500 with DEIF.
DEIF Wind Power Technology has provided a replacement for a COTAS VMP 3500 controller (ground and top) with a new DEIF AWC (Advanced Wind turbine Controller). The replacement included well proven software that could enable monitoring of all the conditions of the wind turbine, which ensured optimized surveillance and health of all systems in the Vestas* turbine. The software includes new control algorithm methods that enhances the production output and a new state-of-the-art thyristor controller for smooth generator cut-in.
