【摘要】 为研究光伏冰箱系统的实时性能,对由太阳电池组件、控制器、蓄电池、逆变器、交流冰箱组成的光伏冰箱系统中的各部件性能进行动态分析,根据各部件参数的逻辑关系确定系统模拟流程图,最终建立可利用实时天气数据预测太阳能光伏冰箱系统性能的系统模型。搭建光伏冰箱系统实验装置,针对昆明地区气象条件下的模拟结果进行实验验证,结果表明模拟结果和实验结果相符。在此基础上进行气候变化对系统性能的影响分析,结果表明系统的性能主要受辐照度、环境温度的影响,电池组件输出电流的大小与辐照度成正相关而与环境温度成反相关。最后从经济性等方面对光伏交流冰箱系统进行可行性分析,提出降低系统成本的方法。更多还原

【Abstract】 Dynamic models for each component of PV refrigerator system which consisted of PV module,controller,storage battery,inverter and refrigerator were developed. The flow diagram of PV refrigerator model was set up withVisio software according to the logical relationship of parameters. Finally,a simulation model for predicting theperformance of a PV refrigerator system under different weather conditions was set up,too. In order to validate thedeveloped simulation model,an experimental system was set up and tested under variable climatic conditions inKunming region. Good agreement was achieved between computational model and experimental test. Further research onthe influence of variable conditions on the performance of PV refrigerator was conducted. The results show that theperformance of PV module is mainly effected by solar radiation intensity and ambient temperature. The output current ofPV module is positively correlated with solar radiation intensity and negatively correlated with ambient temperature.Finally,the feasibility of AC PV refrigerator system from economy aspect was discussed and the methods to reduce costwere proposed.更多还原
