A particular condition monitoring system from Bachman Electronics, is integrated in a plant monitoring system and certified to the requirements of Germanischer Lloyd. This also includes an online remote monitoring station that is also certified, as well as powerful hardware and software components. This also allows reducing life cycle costs of a wind energy plant. Several distringuishing features include these:
Monitoring and protection in the smart grid
GMP232 grid measurement and monitoring module works with the M1 automation system. It measures and analyzes the voltage, current, frequency, power and harmonics (“power quality”) directly on the busbar of the wind energy plant. Together with other plant parameters, the GMP 232 provides differentiated decision criteria to also manage the increased requirements placed on the particular wind energy plant during a grid fault and thus allow the stable operation of the grid.
Networking to IEC61400-25
The MMS server (Manufacturing Message Specification Server) already implemented on the Bachmann M1 automation system collects and provides all data of the wind energy plant. This is presented simply to a higher-level monitoring system using the teleservice protocol for power plants described in the IEC61850 standard.
Safety in cold, heat and condensation
Thanks to a polymer-based sealing of the electronic modules, the coldclimate versions of modules and terminals ensure reliable operation. System components can be used at extreme temperatures from -40 to +70°C, and reliable uninterrupted operation is guaranteed in the temperature range from -30 to +60°C even when condensation is present.
Wind energy plants automated with Bachmann systems are said to produce clean energy worldwide – round the clock with an availability of over 99.96% in real operation. The long term compatibility and availability of all modules over the average 20-year lifespan of a wind turbine provide plant operators additionally with the required security of a future-proof installation and investment.
