摘要
封闭流水式网箱养殖优点是零排放无污染,符合环保养殖要求,缺点是水质容易恶化,水交换与排污能耗大。为了降低能耗并确保设备正常运行,研发太阳能-市电-柴油发电机混合供电系统。基于蓄电池充放电特性,采用最大功率点跟踪(MPPT)和数字信号处理(DSP)技术实现太阳能智能充放电控制与保护,应用双电源自动转换开关技术实现有序混合供电。太阳能月均发电量250 k W·h,日均供电8.3 k W·h,满足负载日均耗电6.6~8.8 k W·h要求。结果表明,在阳光充足情况下,以太阳能供电为主;当出现连续阴雨天气情况下,供电顺序为蓄电池(充满状态可放电3~4 h)、市电、柴油发电机。随着太阳能系统性价比的提高,节能效果将更加明显。
The advantages of aquaculture with closed cage are zero emission,no pollution and environment friendly;while the disadvantages are the proneness of the water quality deterioration and the huge energy consumption for water exchange and sewage. In order to reduce energy consumption and ensure the normal operation of the equipment,a hybrid power supply system of solar energy-mains-diesel generator has been developed. Based on the charging and discharging characteristics of batteries,the intelligent solar charging and discharging control and protection is achieved by using the technology of Maximum Power Point Tracking（ MPPT） and Digital Signal Processing（ DSP）; and an orderly hybrid power supply is achieved by using dual power Automatic Transfer Switching（ ATS）. The average monthly solar power capacity is 250 k W·h and the average daily power supply is 8.3 k W·h,which meets the requirements of the average daily load consumption of 6.6 ~ 8.8 k W·h. The results showed that,the power is supplied by the solar energy on sunny days and the power is supplied by the battery（ discharge for 3 to 4 hours upon full charge）,mains and diesel generator in turn during continuous rainy days. The energy saving effect will be more obvious with the improvement of the solar energy system.
