摘　　要：为验证大功率光伏逆变器的性能及并网安全性,文中提出了一种大功率回馈型光伏逆变器测试平台。该测试平台在实现能量双向流动的同时,解决了大功率设备的网侧谐波和无功污染问题。测试平台主要由光伏模拟源、电源模拟源及一体化监控系统组成。光伏模拟源可模拟光伏阵列的输出特性;电网模拟源可模拟电网正常及故障特性,并能够满足并网设备的零(低)电压穿越。一体化监控系统自动执行预定的试验流程,如效率测试、MPPT测试、电压不平衡测试等。通过实验验证,该测试系统具有较完善的实验功能、优越的性能指标以及较低的功率损耗,能够满足大功率光伏逆变器的测试需求。To ensure the performance of high power PV inverter and network security, a high power test platform is developed. At the same time of bidirectional energy flow, solve the harmonic problems at the network side and reactive pollution problems. The platform eonsists of PV simulation source, power grid simulation source and integrated test system. PV simulation source can simulate the output characteristics of PV array. Power grid simulation source can simulate the normal and false characteristics of power grid and satisfy the LVT. The test platform can execute the scheduled experimental procedure automatically , such as efficiency test, MPPT test and voltage unbalance. With the result of experiment, this test platform have better experimental function, better performance index and lower power loss. Test requirement of highpower photovoltaic inverter can be realized with the platform.
