摘要
抽水蓄能电机通风冷却系统的设计及各部件的温升调控关系到电机运行的可靠性。以某抽水蓄能发电机组为例,建立电机内部热流耦合数学模型,采用有限元软件计算得到该机组通风系统的循环风量和各部分温度场分布。针对机组局部风量分配不均的现象,利用伯努利原理拟定通风结构优化方案。数值计算结果表明,优化后的通风冷却系统结构能够有效改善机组温度分布并具有更好的通风散热效果。
The design of the ventilation and cooling system in pumped storage units and the temperature rise regulation of each component are crucial to the operation reliability of the units.Taking a pumped storage generator unit as an example,a coupled mathematical model of the thermal-flow fields within the unit is established.The circulating air volume of the ventilation system and the temperature field distribution of each component are calculated using finite element software.To address the uneven distribution of local air volume in the unit,an optimization scheme is proposed for the ventilation structure based on Bernoulli principle.The numerical simulation results show that the optimized ventilation and cooling system structure can effectively improve the temperature distribution of the unit and achieve better ventilation and cooling performances.
