摘要: |
统一潮流控制器可以提高输电线路的传输容量,提高系统稳定水平。但当其接入电网后,会使线路中的电压、电流以及阻抗发生变化,可能会造成线路继电保护的误动作。介绍了统一潮流控制器的工作原理。综述了统一潮流控制器以及静止同步补偿器、静止同步串联补偿器接入电网给线路继电保护(包括距离保护、纵联保护)造成的影响。分析了现有的应对方案及其不足,并对后续研究重点给出了相应的建议。 |

Abstract: |
The unified power flow controller can improve the transmission capacity of the transmission line and enhance the system stability level. However, when it is connected to the grid, the voltage, current and impedance in the line will change, which may cause malfunction of the line relay protection. The working principle of the unified power flow controller is introduced. The effects of the unified power flow controller and the static synchronous compensator and the static synchronous series compensator on the line relay protection (including distance protection and longitudinal protection) are summarized. The existing solutions and their deficiencies are analyzed, and corresponding suggestions are given for the future research. This work is supported by National Key Research and Development Program of China (No. 2016YF0900604). |
