Today, there is a large increase in the demand for electricity. The transmission and distribution networks, however, cannot fulfill unbound demands due to the scarcity of resources. Power lines have losses which make the situation more unfavorable for maximum power transfer. Implementing a flexible AC transmission system (FACTS) is one of the best ways to reduce line losses. This paper proposes a FACTS-based method for minimizing the fault current in the system. Switchgear and protection equipment also perform better when this is done. Moreover, due to the reduced fault current of the switched system, a larger amount of power can be transmitted. Static synchronous series compensator (SSSC), static synchronous compensator (STATCOM), and unified power flow controller (UPFC) are evaluated in this case. With STATCOM and UPFC, fault currents are significantly reduced. Furthermore, STATCOM and UPFC can also reduce the fault currents in the power system in addition to voltage regulation and power flow control. A MATLAB/Simulink model is used to evaluate the model’s feasibility.

通过使用 FACTS 设备改善电流来减少故障电流

今天，对电力的需求大幅增加。然而，由于资源稀缺，输配电网络无法满足无限需求。电力线有损耗，这使得情况更不利于最大功率传输。实施灵活的交流输电系统 (FACTS) 是减少线路损耗的最佳方法之一。本文提出了一种基于 FACTS 的方法来最小化系统中的故障电流。这样做后，开关设备和保护设备的性能也会更好。此外，由于开关系统的故障电流减小，可以传输更大的功率。在这种情况下评估了静态同步串联补偿器 (SSSC)、静态同步补偿器 (STATCOM) 和统一潮流控制器 (UPFC)。使用 STATCOM 和 UPFC，故障电流显着降低。此外，STATCOM 和 UPFC 除了电压调节和潮流控制之外，还可以降低电力系统中的故障电流。MATLAB/Simulink 模型用于评估模型的可行性。
