摘要
针对抽油机、潜水泵等野外长期稳定运行,耗能较高的工程状况,提出了利用丰富的太阳能光伏发电辅助电网驱动的低成本电气传动方案。该方案将太阳能发电直流输出、公共电网整流输出在逆变器的直流母线DC侧汇合,采用单台逆变器变频调速驱动电机负载。系统结构简单、成本低,最大限度利用太阳能达到节能之目的。
The low-cost electrical drive system of solar photovoltaic auxiliary power supply to grid was pro- posed ,in view that the submersible pumps are used in long-term stable operation of the field with higher ener- gy consumption. The output of the solar photovoltaic power and the grid rectifier output are jointed at the DC bus to power for motor via the inverter. The system is to pursue the maximum utilization of solar energy pur- poses, with simple structure and low cost.
