This paper presents a real-time simulation of a photovoltaic-based distribution static compensator (PV-DSTATCOM) using the Typhoon HIL 604 simulator, demonstrating its effectiveness in reactive power compensation, harmonic mitigation, and active power injection. The system seamlessly transitions between pure DSTATCOM mode, operating during night-time or when PV generation is zero, and PV-DSTATCOM mode, where it injects PV power while enhancing the power quality. A voltage source converter (VSC) regulated by an indirect current control strategy ensures improved power quality at the point of common coupling (PCC). Real-time simulation results under both balanced and unbalanced PCC voltage conditions validate the ability of the PV-DSTATCOM to mitigate power quality disturbances. Notably, the PV-DSTATCOM effectively reduces total harmonic distortion (THD), maintaining levels between 3.03%-5.58% under balanced PCC voltage and 3.95%-5.93% under unbalanced PCC voltage conditions, generally adhering to or remaining near the acceptable limit of IEEE-519 standards across varying solar irradiance levels and non-linear load conditions. Additionally, it maintains a near-unity power factor operation at PCC and stabilizes the DC-link voltage at 900 V (± 5%), ensuring reliable operation.
本文介绍了使用台风HIL 604模拟器对基于光伏的配电静止补偿器（PV-DSTATCOM）进行的实时仿真，展示了其在无功功率补偿、谐波抑制和有功功率注入方面的有效性。该系统可在纯DSTATCOM模式（在夜间或光伏发电为零时运行）和PV-DSTATCOM模式之间无缝切换，在PV-DSTATCOM模式下，它在提高电能质量的同时注入光伏电力。由间接电流控制策略调节的电压源变换器（VSC）可确保公共连接点（PCC）处的电能质量得到改善。在平衡和不平衡PCC电压条件下的实时仿真结果验证了PV-DSTATCOM减轻电能质量干扰的能力。值得注意的是，PV-DSTATCOM有效降低了总谐波失真（THD），在平衡PCC电压下保持在3.03%-5.58%之间，在不平衡PCC电压条件下保持在3.95%-5.93%之间，在不同的太阳辐照度水平和非线性负载条件下，通常符合或接近IEEE-519标准的可接受极限。此外，它在PCC处保持接近单位功率因数运行，并将直流母线电压稳定在900 V（±5%），确保可靠运行。
