摘　　要：作为清洁的可再生能源,太阳能光伏发电已成为国内可再生能源发展战略的重要内容。运用数字物理混合的硬件在环仿真方法对光伏并网系统的特性进行研究,能够提供便捷的实验条件和准确的实验结果。基于RTDS(Real Time Digital Simulator)实时仿真系统,通过其数模接口同外部DSP构成数字物理闭环,设计了一种光伏并网系统的硬件在环仿真平台,建立了容量为520 kWp的光伏并网系统,实现了最大功率跟踪和并网控制的功能。最后对RTDS系统内的闭环仿真结果进行了分析,验证了所提出的数模混合硬件在环实时仿真方法的可行性和有效性。As one important kind of renewable energy, solar energy has become a key factor of Chinese renewable energy developing strategy. Research on the characteristic of PV grid-connected system by hardware-in-the-loop simulation could provide convenient experiment condition and accurate result. This paper builds a digital/physical hybrid simulation platform based on RTDS and establishes a 520 kWp PV grid-connected system, in which maximum power point tracking （MPPT） and grid-connected control are achieved. At last, the feasibility and effectiveness of hybrid PV system are validated by the analysis of hardware-in-the-loop result in RTDS.
