一种消除补偿器对线路距离保护的影响的方法和装置
摘要：
本发明实施例公开了一种消除补偿器对线路距离保护的影响的方法，所述方法包括：获取补偿器中的串联换流器或补偿器接入的线路的电流，当所述电流大于所述预设电流阈值，且第一持续时间大于第一预设时间阈值，退出所述串联换流器和所述串联变压器；或者当所述电流不满足上述要求时，获取所述补偿器接入的母线或所述补偿器接入的线路的电压，当所述电压小于或者等于所述预设电压阈值，且第二持续时间大于第二预设时间阈值，退出所述串联换流器和所述串联变压器。本发明实施例同时还公开了一种消除补偿器对线路距离保护的影响的装置。
摘要（英）：

The embodiment of the invention discloses a method for eliminating influence of a compensator on line distance protection. The method comprises the steps of obtaining a current of a series converter in the compensator or a line accessed by the compensator, and when the current is greater than a preset current threshold value and first duration time is greater than a first preset time threshold value, carrying out logout by the serial converter or a series transformer; or when the current does not satisfies the above-mentioned demand, obtaining a voltage of a busbar accessed by the compensator or the line accessed by the compensator, and when the voltage is smaller than or equal to a preset voltage threshold value and second duration time is greater than a second preset time threshold value, carrying out logout by the series converter and the series transformer. The embodiment of the invention also discloses a device for eliminating the influence of the compensator on the line distance protection.
