R&D Test Systems has installed the new blade exciter at NWETC in Tianjin, China.

The exciter is one of China's most powerful blade fatigue test equipment, which can test a 120m blade with an excitation power of 220 kW, applying 120 KN force on the blade.

“It has been an interesting project as we faced some challenges, including COVID-19. With great support from NWETC, our project team delivered a good project and set up the first electric exciter installed in China. Furthermore, the new system has the capability to upgrade to a dual-axis test system. The cooperation between NWETC and R&D Test Systems is a win-win for both partners. R&D Test Systems delivers a successful electric exciter in China after continual successes in Europe and the US. NWETC positions itself with a strong technology advantage in blade testing in China and Asia markets,” explains Liwen Hu, Project and Commissioning Engineer at R&D Test Systems.


National Wind Energy Testing & Certification (Tianjin) Co., Ltd. (NWETC), formerly known as SGS-WETC (Wind Energy Technology Centre), was established in 2010 for wind turbine blade tests in China. The company has tested more than 68 blades for static tests and 45 blades for fatigue tests. NWETC has the accreditations of CNAS and CMA and became an IEC RETL in 2019. The main customers of NWETC are top players in China and the Global market.
