The
requirement placed on state-of-the-art wind farms to respond to the power
grid like a single conventional power station requires the use of a central
wind farm controller: communication is required in very high speed. Bachmann
electronic presents ‘bluecom’ – a communication solution specially developed
for smart grids.
‘bluecom’ is based on conventional Ethernet technology and provides
affordable and easy to implement communication for fast and reliable
information exchange in real time. The transmission protocol was
specifically optimized with regard to the particular requirements of
future-proof energy systems. The prime objective of these measures is to
maintain the stability of the grid by enabling energy parks and virtual
power stations consisting of a large number of decentralized power
generation plants to respond quickly.
The new communication protocol ‘bluecom’ Bachmann provides an important
foundation for the transition to a smart grid and the use of regenerative
energies for electricity generation. It is another contribution by Bachmann
electronic to the active development of the power grid of the future.
Service costs and downtimes
under control
An increasing number of wind energy plants are
being fitted with condition monitoring systems
(CMS). These enable you to be continuously
supplied with data relating to the mechanical
components of the turbine. These systems
monitor the body sound of the main components
of the drive train, as well as other measured
values such as ice detection, rotor blade and
gear oil monitoring.
Condition monitoring enables any malfunctions
or incipient wear to be detected and rectified
early on before major damage occurs and
longer downtimes are necessary. Preventative
maintenance involving the exchange of
components within fixed time intervals is
unnecessary. The maintenance intervals can be
adapted as required and planned according to
the actual state of wear. Statistics have shown
that the payback time for the installation of a
condition monitoring system is around two to
four years, depending on the type of system.
Maintenance in periods of low wind
Accurate information about the state of components also makes it possible to
shedule repairs to be carried out in periods of low wind.
Additional savings potential
through attractive insurance
conditions
The insurance conditions for depreciation,
deductibles and premiums for wind energy
plants depend considerably on the manufacturer
and the type of system concerned. However,
insurance companies usually reward the
installation of a condition monitoring system
by offering premium reductions of up to ten
percent, particularly when the CMS has obtained
certification from Germanischer Lloyd.
Additional diagnostics reliability through online remote monitoring
Bachmann electronic offers a condition
monitoring system fully certified to the
requirements of Germanischer Lloyd, including
an online remote monitoring station that is
also certified, as well as powerful hardware
and software components. The WebLog Portal specially developed for this
provides an interface to the Ω-Guard® turbine diagnostics system, and
enables worldwide access to the status data of the installation being
monitored.
Expert service – on site and via the Internet
The success of a condition monitoring system
greatly depends on its proper installation,
parameterization and commissioning, as well
as on the fast and correct response to reported
status changes. Our experts therefore take care
of all requirements on site, right through to
the training and instruction of your personnel.
Modern teleservice functions for remote
applications include online monitoring via a
secure Internet connection, thus allowing access
worldwide. Our monitoring center currently
monitors well over a thousand condition
monitoring systems. The outputs of these plants
range from 250 kW to 5 MW.
Safety engineering under control
The safety components from Bachmann
electronic are ideally prepared for use in wind
turbines. Operational control, safety engineering
and operating devices are perfectly matched
and offer open communication. The fastest
possible response times, intuitive operation and
comprehensive diagnostic options guarantee the
highest possible level of safety.
The safety modules can be arranged within
the wind turbine as required, thus enabling
the implementation of individually tailored
solutions. Safety channels that are not required
can be used as standard digital I/Os without
any restrictions. Safety relays can be replaced
thanks to the 2A outputs of the remote SDO208
output module. This saves space, wiring effort
and additional costs.
Keeping it safe with Bachmann
It goes without saying that the safety modules
of Bachmann electronic, together with the
necessary programming tools and function
blocks, have been certified by TÜV Süd for
compliance with the relevant standards –
including ISO 13849 and EN 954. UL508
approval also ensures safety when operating
in North America. All modules are available as
coldclimate versions (-40°C to +70°C). Safety is
thus also guaranteed in extreme environmental
conditions.
Benefits for manufacturer and
operator
Programmable safety engineering makes the
practical implementation and series production
easy. It enables the secure monitoring of all
the internal states of a wind turbine during
operation, including the safety circuits, from
anywhere in the world. Bachmann electronic<
offers you tailored solutions based on the
experience gathered from thousands of
successfully used control components in wind
energy plants all over the world.
Openness in hardware and software
The M1 system operates as a real-time system.
Different open-loop and closed-loop control
programs are adapted in modules and run
simultaneously in a preemptive multi-tasking
environment. Like the hardware, the software
is also modular and can be structured and
extended as required following our “without
limits” principle. The controller offers additional
reserves for expansions or plant-specific
adaptions.
Functionality means “Ready -to -Use ”
The modular M1 system offers a wide range of
hardware, consisting of over 200 devices and
modules. This system contains a large number
of configurable function blocks for all necessary
machine functions, such as visualization,
networking, closed-loop control and diagnostics,
to provide you with all the basic functions from
the start. Here we place tremendous value in the
fact that all tools have been developed according
to international standards, and can also be
integrated and parameterized flexibly.
Equipped for challenging climates
The coldclimate modules of Bachmann
electronic – a solution for all applications in
demanding climatic conditions, particularly
where maximum plant availability is critical.
The coldclimate modules are the first choice
for decentralized power stations such as wind
energy plants, CHP units, hydroelectric or
solar power stations. For you this means:
Safe operation, even with transient extreme
temperatures as low as -40°C and when
condensation is present.
Today bioenergy is an important element of the global energy supply. This
covers a broad range of applications, thus requiring an open and highquality
automation system. This forms the basis for a wide range of bioenergy
solutions and is used by machine and system suppliers, as well as system
integrators,
worldwide.
The Bachmann electronic range of modular hardware offers the fl exibility required for individual expansions or plant-specifi c adaptions.
