9.xMW WTGS in Desert, Gobi and Wilderness

为响应国家在“沙戈荒”规划建设大型风电光伏基地的政策，中车株洲所推出的“沙戈荒”定制化大功率风力发电机组，针对“沙戈荒”风资源条件好、基地规模大、环境特征显著、通道外送为主等特征制定了“沙戈荒”机组环境适应性方案，继承了高寒抗风沙，高原机车优良基因，完成了多项关键创新技术研究与突破，根据具体的消纳场景推出9.xMWD225风力发电机组平台，助力生态链建设，让沙戈荒“只此青绿”。

In response to the national policy of planning and constructing large wind power PV bases in the "desert, gobi and wilderness", CRRC Zhuzhou launched the customized high-power WTGS for "desert, gobi and wilderness", and formulated the environmental adaptability scheme for the WTGS used in "desert, gobi and wilderness" according to the local characteristics of abundant wind resource, large base scale, obvious environmental characteristics and main transmission of electricity to outside. The WTGS inherits the excellent features of alpine sand resistance and highland locomotives. CRRC Zhuzhou completed a number of key innovative technology research and breakthroughs, and launched the 9.xMWD225 WTGS platform according to the specific consumption scenarios to help the construction of the ecological chain and make the desert, gobi and wilderness "green".
