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
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
