摘要 针对传统逆变器供电方式单一不环保、工作模式不灵活的问题,文章研究了光伏和锂电池双供电模式的逆变器,并基于该逆变器搭建了10 kW储能系统试验平台。在并网运行状态下,设计了稳态试验和动态试验。试验结果表明:稳态运行时,该逆变器能平稳输出与电网同频同相的电压电流,且电流谐波畸变率小,直流电压波动在允许范围内;动态运行时,该逆变器在负载切换瞬间直流电压波动小,恢复时间短。因此,光储一体逆变器能够很好地满足10 kW储能系统的技术要求。 Aiming at the problems that the traditional inverter power supply mode is single and not environmentally friendly,and the working mode is inflexible,this paper studied the inverter of the photovoltaic and lithium battery dual power supply mode.Based on the Inverter,this paper built a 10 kW energy storage system test platform,and designed steady-state tests and dynamic tests in the grid-integrated operation state.The test results prove that,in steady-state operation,the solar-storage integrated inverter r can output voltage and current with the same frequency and phase as the grid smoothly,and the current harmonic distortion rate is small,and the DC side half-bus voltage fluctuation is within the allowable range;In dynamic operation,the inverter has a small DC voltage fluctuation at the moment of load switching,and the sequence of starting up and grid-connecting and then loading cannot be switched;Therefore,the solar-storage integrated inverter can well meet the technical requirements of 10 kW energy storage system.
