摘要
提出大距离差直流汇流电缆差异化配置技术,按照光伏组件串至汇流箱、汇流箱至逆变器间线路压降应趋于一致的配置原则,根据距离远近采用不同截面电缆,在略增加建设成本的情况下提高光伏电站输出功率。最后通过仿真试验和工程实践验证该技术的有效性和经济性。
We proposed optimal design of DC collecting cable under the large difference of distance. In accordance with a principle that the voltage drop between PV and junction box, junction box and inverter tends to be consistent, the longer of distance, the bigger section cable use. Consequently, output power of PV power plant improved by slightly increased cost. Finally, effectiveness and economy of this technique is verified by simulation test and engineering practice.
