本文通过一个真实的逆变器和真实的多台同步电机的实验研究，为评估伪同步功率逆变器的有效性提供了一个令人信服的论据。由于可再生能源正在迅速引入电力系统，为了平衡供需，同步电机将被迫停止运行。在电力电子装置中实现虚拟惯性是解决同步电机少的电力系统稳定问题的有效方法之一。在以往的研究中，包括作者的一些研究，已经对伪同步功率逆变器进行了理论和简单的实验研究。然而，为了通过引入伪同步功率逆变器来实现稳定的电力系统，似乎还需要进一步的现实实验分析。在现实实验研究的背景下，我们构建了一个由多台同步电机、带故障仿真系统的两线输电线路和一个真实的逆变器组成的小型、现实的电力系统。逆变器由来自数字信号处理板(PE-Expert 4)的门信号控制，数字信号处理板产生信号，从而使逆变器实际上具有同步功率。从实验结果可以看出，即使在实际的实验系统中，所提出的伪同步电源逆变器也能成功工作。
This paper provides a convincing argument for assessing effectiveness of a pseudo-synchronizing power inverter by experimental study using a real inverter and real multiple synchronous machines. Since the renewable energy sources are being rapidly introduced to the power system, synchronous machines will be forced to stop in order to balance the supply and demand. The implementation of virtual inertia into power electronics devices are well known as one of effective ways to stabilize the power system with few synchronous machines. In previous researches including some studies by authors, the theoretical and simple experimental studies for pseudo-synchronizing power inverter have been already examined. To realize stable power system by introducing the pseudo-synchronizing power inverter, however, further realistic experimental analysis seems to be necessary. In the context of the realistic experimental study, we construct a small scale and realistic power system with multiple synchronous machines, two-line transmission lines with a fault simulation system, and a real inverter. The inverter is controlled by gate signals from a digital signal processing board (PE-Expert 4) which generates the signals so that the inverter has the synchronizing power virtually. It can be seen from the experimental results that the proposed pseudo-synchronizing power inverter can successfully work even in the realistic experimental power system.
