Monitoring for China

The German company 8.2 Monitoring GmbH has received an order from the Chinese manufacturer Zhejiang Windey to equip 66 1.5 MW class wind turbines with condition monitoring systems (CMS). According to the company, 8.2 won the order against competition from two local firms and one international vendor. Software for data collection, which was developed internally, and the "VibraLyze TM Pro" analysis software will be used.

The "Danjinhe Project“  and the "Delinha Project“ consisting of 33 turbines each, will be completed by safety packages from local partner Titan New Energy Technologies, Hangzhou, and the CMS technology made in Germany. The drive train, i.e. the main bearing, gearbox and generator will be monitored. For particular projects, CMS hardware provided by control systems supplier Beckhoff Automation GmbH will be used. Titan New Energy acts as the systems integrator.

Bernd Höring, surveyor and executive manager at 8.2 Monitoring GmbH, explains: "In contrast to other CMS suppliers, who supply a complete CMS consisting of their own hardware and software, we focus on the control systems manufacturer market. In general, control systems manufacturers neither have the knowledge to create functioning analysis and data management software for larger wind farms, nor do they want to offer data analysis services. However, it is impossible to sell CMS hardware without analysis software and service. We can offer the firmware, the analysis software and our know-how to the control systems suppliers."

Höring adds that a special aspect of the Chinese market is the fact that turbine manufacturers usually have two or three control systems suppliers and not only one.  By using the software solution provided by 8.2, the manufacturers can buy CMS hardware from different manufacturers and operate them using a single software system.

For 8.2 Monitoring GmbH, the order from Zhejiang Windey is not the first from China. In late 2010 the first Chinese offshore wind farm was equipped with CMS software. In addition to this, a pilot installation at the Chinese manufacturer Guodian United Power has been running since March 2012.

Sometimes one and one add up to more than the mere addition of numbers. Structural Health Monitoring (SHM) of rotor blades is a complex and demanding task that requires very good hardware as well as professional data analysis in order to be able to make really precise and early statements about structural damage to the rotor blade. For this reason, two specialists have now joined forces to offer wind farm operators the best possible combination of forces on the market.
