Turbine Update

The turbine was returned to service mid-October,2014 after maintenance/repairs to the converter.

Maintenance update

As you may be well aware, the ExPlace Turbine has been shut down for maintenance and repair work for the past few weeks. It has been experiencing trouble with the new converter. The converter was faulting out once turbine hit ~11 rpms (when it starts to generate power).   Our service provider, EWT, has determined that there is an issue with the control board in the converter that controls the conversion of power.  A new part had to be ordered and shipped to the site.  The new part was installed on Tuesday, July 28th, which appeared to allow the turbine to run, but the converter would continue to fault.  EWT is working with SETAC right now to ascertain what the source of the problem is with regard to the new converter and the new control board.

We appreciate your patience and hope to resolve the matter as soon as possible.

 

Yours sincerely,

TREC Education: Climb the Turbine Event 2013

Bullfrog1 ArianeLejla

From Oct. 5th – 8th 2013, over 50 people climbed the Windshare turbine during the 2nd annual Climb the Turbine fundraiser presented by TREC Education. Participants were given a first hand look at how wind power works and got the chance to enjoy the fantastic view from the top. The event is truly one-of-a-kind, and as a result, participants came from across Ontario, British Columbia, Alberta and Virginia to climb the turbine. 

The event is a great opportunity to utilize the turbine as a great renewable energy educational experience – de-mystifying the technology and bringing greater understanding of how wind turbines generate electricity. Also, the event raised $15,000 for TREC Education’s Kids’ World of Energy classroom program. This will result in hundreds more students engaging and learning about the science and advantages of renewable energy and energy conservation. The program facilitates workshops in classrooms across Ontario, providing hands-on, curriculum-linked activities that enable students to design and build functioning renewable energy systems (i.e. LED bulb powered by a small wind turbine).

If you are interested in learning more about the event, please contact Wesley Normington at wesley@trec.on.ca.

Plaque Installation

The Board is pleased to announce that a plaque to commemorate the first WindShare Co-op members was installed this summer and is available for public viewing. The plaque is situated on the body of the turbine to the left of the entrance door. If you are one of WindShare’s original Co-op members, we invite you to visit the turbine on the grounds of the CNE to see your name on Toronto’s iconic urban turbine.

Turbine Update

Upgrade of electronic rotor control mechanism and installation and commissioning of the new converter was completed and power started flowing to the grid on March 20. Since that date production of about 120,000 KwH has been achieved. This is normal for this time of year. There was a shutdown on Apr 19 caused initially by an alarm from gusty winds which could not be reset. This was resolved between EWT and our local technician on the morning of Apr 22. The fault was caused by faulty wiring of the alarm reset circuit during the installation and has now been corrected. The turbine is now producing normally and we are pleased with the improved information available from the new display unit in the converter.

We thank you for your patience and continued support.

Sincerely,

Turbine Update

Since July of 2012, the turbine has experienced reliability problems with regard to the turbine’s Technocon converter. Various repairs have been made to the Technocon converter between August and December of 2012 but the turbine has not been producing energy reliably through that period.

Many of the Lagerway turbines in Europe have replaced their Technocon converters prior to 10 year’s operating life because of similar issues.

The Joint Venture management have agreed to order a replacement
converter from SETEC, which will be installed in early March 2013 along with associated control upgrades. This replacement converter is more efficient, provides increased production, improves reliability and will extend overall life of the turbine by approximately 10 years.

During January and February of 2013 the turbine has not been producing power but is programmed to “free-wheel” for the following reasons: a) rotation reduces potential build-up of ice on blades; b) rotation keeps the generator rotor from getting damp; and c) rotation maintains the lubrication of the main bearing. The “free-wheel” operating mode is protected by all the normal safety controls (multiple blade pitch control and rotor brake) inherent in the turbine. We will continue to keep you informed of its progress.

Sincerely,

Turbine Update

After installing a spare Nacelle Control board which had been hand carried from Holland on Tuesday and changing out 2 more Dynex IGBTs in the converter, Bettink technicians completed the turbine repair and the turbine started producing power December 12.

Turbine Update

After field testing, the replacement control system for the converter arrived on Nov. 16 from Holland. A technician installed it this week but there is still no connection between the nacelle and the converter.  The technician has been in communication with our servicer in Holland, Bettnick, but he has not been able to solve the problem to date.

Other spares are expected to leave Holland by Nov 23rd. We have also arranged for a Bettnick technician to return to Toronto at the beginning of the week after the spares have arrived. This is expected for Dec 3.

We will continue to inform you of any progress.

Sincerely,

Turbine Update

We have had a series of cascading faults this summer related to the converter. We would rectify one problem then another would occur. To add to the delays, the components are to European specification and are at least 10 years old. In the case of the motorized breaker switch in the converter, the part was out of stock and had to be manufactured.   At present the control system for the converter has failed and has been sent to Holland for repair. In addition, the interface computer has recently failed. The operators of an LW52 in Alberta have kindly offered to help with a replacement.

We expect to be back in operation as soon as possible after we receive functioning spares.

Turbine Update

The ExPlace turbine is still down with problems in the Technicon converter. Replacement parts have arrived and a technician familiar with the converter will arrive on October 1. We hope to have the turbine up and producing as soon as possible.

We will keep you informed of progress.
