Orbital
Energy provides both custom designed/manufactured control systems and
it's Vecs 9000 Controls Framework based on leading Industry components
that have all been proven to work together seamlessly.
Our control systems can be used with new
installations or can be integrated into existing systems to replace
obsolete or unreliable equipment.
All of our systems are fully documented
and designed to ISO 9001:2000 standards.
Custom made SIL 2 and SIL 3 solutions are
also available upon request. As
standard our control systems include both plc based and hardwired
protection circuits, allowing operators to override the plc and manually
stop the turbine. A watchdog timer protects the system against PLC
failure, again stopping the gas turbine in the event of component
failure. The Vecs 9000 framework
uses mainly off the shelf components which we have tested in integration
with each other, so that we can provide the customer with a variety of
choices and the assurance that they will all work together. The
diagram on the left shows the full extent of a Vecs 9000 framework
control system. The customer can specify which of these components they
require or an Orbital Energy representative can provide a recommended
configuration.
Orbital Energy uses
the highest quality industry standard components to avoid the customer
from being locked into proprietary upgrade paths. All Vecs 9000
components come with fully documented interfaces to allow third parties
to integrate with the purchased control system. Fuel
Skid
Orbital Energy custom builds fuel skids based on each projects
requirements. Gas, liquid or duel fuel skids are available, with either
valve or pump driven control interfaces. All the interfaces can be
designed to work with either the standard Vecs 9000 framework or to
fit in with an existing control system. Instrument
Probes
Most equipment is supplied with various industry standard probes to
monitor vibration and temperature. The Vecs 9000 framework is designed
to interface with these. If the control system is replacing an older
control system on existing equipment then damaged/obsolete probes can be
replaced with comparable items. Physical
Instrumentation
In many cases customers may require physical gauges and switches to
control the engine. Our custom fabrication workshop can either
copy the ergonomics of existing control panels or design and build
new units. PLC - Central Control
Computer
Our Central Control Computer
solution is an unmodified Allen-Bradley ControlLogix 5550/5560 PLC, running
Orbital Energy control software. We have used this PLC in a wide variety
of gas turbine control systems and it has impressed both ourselves and
our customers with it's
reliability and response speed. Protection
Systems
If separate hardwired protection systems are required, then both
VibroMeter and Bently Nevada provide excellent solutions which can
easily be integrated into the rest of the Vecs 9000 framework. Control
HMI
Orbital Energy uses both Allan Bradley RSView and Microsoft Visual
Studio based HMI systems. These can be configured to work with existing
control systems or integrated into a new Vecs 9000 system. HMI's are
tailored to suit each project's individual requirements. Popular options
are extreme weather casings, touch-panel displays and control room
mounted displays. Monitor
HMI
This is usually the same as the control HMI, except without any
control over the unit (with the exception of an optional emergency stop
function). Data Analysis Station
Orbital Energy can provide either a computer or software
installation of the Orbital Energy Data Analysis software that allows
either long term analysis of engine performance or short term analysis
for fault finding and problem identification. In
the case of the data logging of the engine, a programming API is
available to allow customer analysts to interface with the internal
database and extract information. |
