摘　　要：太阳能作为一种新型的可再生能源近年来得到了广泛的应用。光伏并网技术成为有效利用太阳能发电的核心和关键。通过分析传统光伏并网逆变器控制策略,提出一种具有功率跟踪的固定开关频率的电流控制技术。仿真结果表明,并网电流与电网电压基本同频同相,并网系统的功率因数近似为1,满足设计要求。The solar energy was applied widely in recent years,as a kind of renewable energy. Photovoltaic （PV） grid technology became the key and core of the most efficiency ways of using solar energy. A current control technology with a fixed switching frequency which could track the power was put forward,through analyzing the traditional PV grid inverter control strategy. The results of the sumulation showed that the network voltage and gridconnected current were basically synchronic. And the power factor of grid system was 1 approxomatively,which met design requirement.
