一种半波长交流输电线路的潜供电流主动抑制系统
摘要：
本发明提供了一种半波长交流输电线路的潜供电流主动抑制系统，所述系统包括并联换流器，其一端与外接电源连接，另一端与半波长交流输电线路并联；并联换流器，用于向半波长交流输电线路输出预设电流，以抑制潜供电流。与现有技术相比，本发明提供的一种半波长交流输电线路的潜供电流主动抑制系统，通过控制并联换流器向半波长交流输电线路输出预设电流，可以将潜供电流抑制在期望的水平以内，进而提高半波长交流输电线路的故障点电弧熄灭速度。
摘要（英）：

The invention provides a secondary arc current active suppression system for a half-wavelength alternating current transmission line. The secondary arc current active suppression system comprises a shunt-wound converter, wherein one end of the shunt-wound converter is connected with an external power supply while the other end is connected with the half-wavelength alternating current transmission line in parallel; and the shunt-wound converter is used for outputting a preset current to the half-wavelength alternating current transmission line to suppress the secondary arc current. According to the secondary arc current active suppression system for the half-wavelength alternating current transmission line provided by the invention, by controlling the shunt-wound converter to output the preset current to the half-wavelength alternating current transmission line, the secondary arc current can be suppressed within an expected level, so that the fault point electric arc extinguishing speed of the half-wavelength alternating current transmission line can be further improved.
