For the efficient power allocation of the distribution line, several studies on intelligent distribution management systems that enable connection or separation between distribution networks are being conducted. However, in case the systems are linked together and if the voltage and phase of each distribution network are different, uncontrolled circulating current and inrush current flow into the line. To resolve this, we introduced the active phase controller (APC) as a solution and performed an analysis using the capacity calculation method for the APC connected to each distribution network. When connecting lines between distribution networks, the phase of each contact was ensured to be the same. Specifically, the phase value compensated by each APC is different because the amounts of active power and reactive power to be controlled are also different. In this study, we analyzed the APC capacity according to the impedance state of the distribution line and calculated the APC output voltage for the phase matching of each distribution network at the connection point. As a result, the minimum design capacity of APC was derived; moreover, simulation results were used to validate the analysis.

有源电网并网有源相控制器的容量研究

为了有效地分配配电线路，正在进行一些关于智能配电管理系统的研究，这些系统可实现配电网络之间的连接或分离。但是，如果系统链接在一起，并且每个配电网络的电压和相位不同，则不受控制的循环电流和涌入电流会流入线路。为了解决这个问题，我们引入了有源相位控制器（APC）作为解决方案，并使用容量计算方法对连接到每个配电网络的APC进行了分析。连接配电网络之间的线路时，应确保每个触点的相位相同。特别，由于要控制的有功功率和无功功率的量也不同，因此每个APC补偿的相位值也不同。在这项研究中，我们根据配电线路的阻抗状态分析了APC容量，并计算了连接点处每个配电网络的相位匹配的APC输出电压。结果，得出了APC的最小设计能力。此外，仿真结果用于验证分析。
