Experimental Analysis of A Cooling System for Wind-Driven Generator Stator

摘要

A novel cooling system with cooling channels is proposed for the stator of 3MW wind-driven generator.An experimental platform is built to investigate the performance of the cooling system with different loads.At30%,50% or 80% generator loads,the temperatures meet the design requirement.However,it is a little over the requirement at 100%load,duo to experimental errors and some unknown thermal resistances.In the test at 100%load,the developing trends of the parameters of these two generators are similar and only minor differences occurs when they reach steady state our work can be benefit for the design and improvement of MW wind-driven generator cooling solutions.
