Wind Energy monitoring, and visualisation on a single CPU. PC-based Control seamlessly integrates wind turbine Condition Monitoring in the existing automation system: The high-precision EL3632 EtherCAT Terminals for vibration measurement or the EL3356 0010 for analysis of strain gauges can be easily added to the existing I/O system. The user’s CMS software, which is integrated in the control system via an open interface such as OPC, facilitates analysis and initiation of downstream services. Furthermore, Beckhoff will present its new CX5100 Embedded PC series as a central control platform for wind turbines. The compact and robust DIN rail-mountable Embedded PCs with a directly attached I/O system can be equipped with one, two or four processor cores. The automation software TwinCAT 3 supports multi-core technology, making it possible to implement computing-intensive tasks such as Condition Monitoring on a separate core. Hall B6, Booth 309 The devices in the new Embedded PC series CX5100 from Beckhoff are optimally suitable as central control system platforms for wind turbines.

In order to install the system, the sensors have to be bolted to an installation plate, and the cables have to be professionally laid and connected to the peak analyser in an orderly fashion. The software guides the user through configuration and initial start-up, which means that special knowledge of diagnostics is not necessary. After this, the system is ready to start immediately. The peak analyser can also be attended by operator personnel so that personnel costs are kept low. The system displays irregularities using plain text messages, which enables an overview to be kept. If analysis of spectra by an expert is necessary for definitive maintenance decisions, aids including a waterfall diagram, spectrogram or the representation of individual characteristics over time are available. Hall B3, Booth 121 The GfM peak analyser provides a clear view of irregularities and helps in their analysis. Photo: GfM Munich-based HAWE Hydraulik SE has developed a braking module that allows wind turbine azimuth brakes to function quietly. Optimisation of the hydraulic interconnection enables the residual brake pressure to be dynamically tracked and kept constant. This prevents squeaking noises caused by uneven spots on the brake disc ring. The new brake module is compact since the function module and the intermediate plate, which was previously located separately, are now integrated in a common housing. This reduces the installation costs and increases operational safety. The function module contains valves for applying and releasing the brake, adjusting the residual holding pressure for the realignment of the nacelle to the wind and flushing the brake circuit during maintenance work. With a leakage oil-free 2-way pressure regulation valve, the maximum permissible braking pressure can be set and the hydraulic equipment pressure accumulator can be optimally dimensioned. Hall B7, Booth 428 The new HAWE brake module enables squeak-free nacelle rotation.

Solutions on show at WindEnergy are the result of Comer Industries’ product evolution over the years. Its display will include the PG-1603 DSP and the PG-1904 yaw drives. PG 1603 DSP, featuring a built-in torque limiter, is 28 Sun & Wind Energy 8+9/2014
