活塞式发动机主要由活塞、连杆、曲轴等部件组成,其工作原理是通过燃料的燃烧产生的气体压力,将活塞向上推动,使连杆带动转子旋转。而转子式发动机则是通过外部能源(如电能、光能或气体流体的流量)来驱动发电机的转子旋转。 因此,将活塞式发动机与转子式发动机相结合的一般思想是根据实际应用情况采用一定的优化方法对两者进行协同优化。具体而言,常采用“以小博大”原则,即地使电量少得多的小装置承担大部分工作以减少整体能耗。例如地震应急供电中常使用“风-气”并系方式(Wind-Gas Hybrid System, WGHS) :当风速不够时(也就是说风速不能保证供应所需要的能量时) ,再额外补充天然气发生器产生的...<未完>点击进入 -
