摘 要： 结合并网逆变器最大功率点跟踪(MPPT) 功率跟踪能力的特点，介绍了一种光伏并网型逆变器静态MPPT 效率的测试方法。按照标准要求计算光伏组件的MPPT 曲线，并用I -V 源模拟此曲线。通过功率分析仪等测试设备，测量并网逆变器的端口电压、电流值、功率值，与理论最大功率相比得出MPPT 效率，来实现对MPPT 的测试，数据处理、分析证明了该测试方法的正确性。

Abstract: Combined with features of grid-connected maximum power point tracking (MPPT) capability, this paper introduced a test method for static MPPT efficiency of photovoltaic grid-connected type of inverter. According to requirements of standard, MPPT curves of photovoltaic components were calculated and these curves were simulated with I -V source. Via power analyzer etc test equipment, terminal voltage, current value and power value of grid-connected inverter were measured. MPPT efficiency was obtained by comparing with theoretical maximum power, so as to realize test of MPPT, and data processing. The analysis proved the correctness of the test method.
Key words: grid-connected inverter; photovoltaic; maximum power point tracking; power analyzer
