SCADA solution started in early 08 addressing some of the issues of the
00:08
renewable energy market.
00:11
We were being asked by several operators stating that they needed help.
00:17
What's driving the operators here at Windland or operators like Windland to
00:25
implement a SCADA system is because of the purchase power agreement between
00:28
them and the utility has come up for renewal. Part of the stipulations of
00:34
those renewals is to have a SCADA system that will allow for curtailment in a
00:39
short amount of time. And, when there's a surplus of energy sometimes the market
00:44
goes to a negative and it doesn't let the operator make any money. And if it's
00:49
a curtailment request that needs to be addressed within 10 minutes or they’re
00:53
playing the (energy) market with data that comes in at 5 minute or 15 minute intervals they
00:57
have to have the agility to do that.
01:02
The majority of our clients have legacy turbines; older equipment, a mixed bag of
01:08
different ages, different types, different manufacturers, and many of them do not
01:12
have any communications whatsoever. So, the first and primary goal is to get
01:17
communications back to the central office for them so they can at least
01:20
communicate with the turbine remotely rather than they do things manually.
01:25
SCADA Solutions Wind Capture Platform has used the Opto 22 to give us the
01:32
aggregated control of the entire wind site. That also is monitoring the energy
01:38
market at the same time. Giving them those opportunities to make that call of
01:42
weather curtailed completely because they're not making any money or to keep
01:45
operating. The groov platform on top of our base controller the Opto 22
01:52
gives us the ability to do things mobiley while operating the farm. Looking
01:58
at the market, looking at the operation, looking at a fault of a turbine, all of
02:02
these things are achieved through that same platform.
02:07
In addition to the software that was developed for SCADA controls we had to
02:12
develop specialized hardware. That hardware includes a 900 megahertz radio
02:17
with its small proprietary motherboard. That allows us to give those controls to
02:23
those turbines and the bidirectional communication. There's a lot of mandates
02:29
as far as security goes. We're dealing with energy. We're dealing with the
02:33
utility. All those have a different requirement for security and their certificates
02:39
were easily implemented by the groov and Opto 22 platform.
02:46
You know the the ability to say look I don't have to go up that thing today
02:49
with the harness and the you know the catch and all that stuff they have to wear.
02:54
Having that gave system available right there in a hand just mitigates all of that.
02:59
The beautiful thing about the whole platform is it's so easy to add
03:05
functionality. You know, we have a base platform. This is the start, stop, reset-default.
03:11
But, if they want more we can do that. Using Opto 22, using the groov platform
03:18
allows us to do almost anything the customer wants. It’s all up to what's
03:23
needed, what's required,
03:24
and what's going to get them into the next 20 years of service.
