摘要

介绍了长洲光伏电站的运行情况,由于光伏组件发电有时段性,而光伏一体化升压变长期投入运行,消耗厂用电,为了减少升压变的空载损耗,避免产生系统反送电,通过优化控制流程,将光伏升压变随着逆变器同时投入、退出运行。
        An introduction was made on the operation information of Changzhou Photovoltaic Power Station. Photovoltaic power generation is not continuous while photovoltaic integrated boost transformer keeps operating continuously for a long period which leads to unnecessary power consumption. In order to reduce no-load loss of transformer and avoid reverse power transmission from the system, the control program was optimized to make the transformer and inverter be put in or out of operation synchronously.
