基于功率硬件在环仿真方法(或称数字物理混合仿真方法)，为分布式发电装置接入配电网及微电网的运行工况，设计了一种硬件在环测试接口装置。根据配电网及微电网常见的电能质量问题(如频率偏差、供电三相不对称及谐波等)，提出了一种三相四线制的接口装置硬件结构设计，并开发了基于准比例谐振控制的接口策略，以消除接口放大过程中引入的放大幅值误差。以配电网及微电网中可能出现的频率波动、电压三相不对称以及电压含谐波为研究算例，对所提出的接口装置和控制策略进行了仿真验证，证明了该装置和控制策略的有效性及准确性。

Based on power hardware in loop (PHIL) simulation method, which might be called the digital physical hybrid simulation, a kind of hardware in loop testing interface device is designed. According to the frequent power quality problems, such as frequency deviation, three-phase unbalance of supply source and harmonics and so on, a hardware structure of interface device for three-phase four-wire system is designed, and an interfacing strategy based on quasi-proportional resonant control (Q-PR control) is developed to eliminate the amplitude error caused by the amplification of the interface. Taking the frequency fluctuation, three-phase voltage unbalance and voltage containing harmonics, which may appear in distribution networks and microgrids, as simulation cases, the proposed interface device and control strategy are validated to prove both effectiveness and accuracy of the proposed device and control strategy.
