Design and Numerical Simulation of Cooling Systemfor High-power Wind Generator
As the capacity of wind generator continues to increase and the heat dissipation space decreases,it brings great challenges to the design of the whole turbine.Accurate calculation of generator temperature rise is of great guiding significance for its high power density.Taking the offshore high-power 15MW integrat-ed permanent magnet synchronous wind generator as an example,based on the theory of computational fluid dynamics and heat transfer,a three-dimensional steady-state flow-temperature simulation model including water jacket cooling,internal circulation air-cooling and generator components were constructed,and the flow field characteristics of the motor and the temperature distribution of the main components were studied and analyzed.Finally,the temperature rise test verified the accuracy of the simulation analysis and the ra-tionality of the design of the generator heat dissipation system.
