高寒条件下空冷岛风机集群永磁直驱系统批量改造分析

Batch Transformation Analysis on Permanent-Magnet Direct-Drive System of Air-Cooled Island Fan Cluster under Alpine Condition

鄂温克电厂通过科研立项,论证了空冷岛变频永磁直驱系统在高寒条件下的适用性、易维护性,并通过运行实测确定了变频永磁直驱系统在各种转速下具有良好的节能效果。为更好的推进空冷岛风机集群变频永磁直驱改造,针对其批量改造的可行性进行了系统分析。

Through establishing the scientific research project of Ewenke Power Plant,it is demonstrated that the variable-frequency permanent-magnet direct-drive system of air-cooled island under alpine condition is applicable and ease of maintenance,and it is determined through operation measurement that the system has good energy-saving effect under various speeds.In order to better push forward variable-frequency permanent-magnet direct-drive transformation of air-cooled island fan cluster,the feasibility of batch transformation is systematically analyzed.
