        摘 要:特高壓輸電線路發生直流閉鎖故障會導致有功功率缺失,使電網頻率下降?;?ldquo;電網友好”技術,分析了包括頻率響應負荷與電壓響應負荷的功率調節特性,并提出了相應的響應策略。算例仿真表明,該技術可以在負荷側響應電網頻率緊急狀態,從而減少直流閉鎖等故障下負荷的切除量,有效提高電網頻率的穩定性。
        關鍵詞:頻率穩定;電網友好;頻率響應;電壓響應;控制變量

        Abstract: The direct current blocking fault in ultra high voltage (UHV) transmission line will lead to the loss of active power, which will make the grid frequency decrease. Based on the "grid friendly" technology, this paper analyzed the power regulation characteristics including the frequency response and voltage response loads and proposed the corresponding response strategy. The example simulation shows that this technology can respond to the grid frequency emergency state at the load side, so as to reduce the amount of load cut off quantity under the conditions of direct current blocking etc, which improves the stability of the grid frequency.
        Key words: frequency stabilization; grid friendly; frequency response; voltage response; control variable
