【摘要】 采用市电代替储能元件,提出并设计一种基于市电补偿的光伏逆变器。该系统由太阳电池、市电、DC-DC变换器及逆变器组成。系统采用太阳电池和市电共同供电,设计其输出功率平衡方案,在保证太阳电池最大输出功率的同时,通过市电补偿调节逆变器输出功率,以满足负载要求。实验室研制一台市电补偿光伏逆变器样机,并通过仿真和实验验证该系统的有效性。更多还原

【Abstract】 Based on the compensation using the city electricity,a photovoltaic inverter was proposed and designed,taking the city electricity in stead of energy storage element. The system consists of photovoltaic cells,power,DC-DCconverter and an inverter. System uses photovoltaic battery and power supply design together,the output power of thebalancing scheme,in which the maximum output power of photovoltaic cells at the same time,the city powercompensation regulation of inverter output power,in order to meet the load requirements. A power compensationphotovoltaic inverter prototype was developed in laboratory,and the effectiveness of the system is verified by simulationand experiment.更多还原
