    摘 要:特高壓輸電線路發(fā)生直流閉鎖故障會(huì)導(dǎo)致有功功率缺失,使電網(wǎng)頻率下降?;?ldquo;電網(wǎng)友好”技術(shù),分析了包括頻率響應(yīng)負(fù)荷與電壓響應(yīng)負(fù)荷的功率調(diào)節(jié)特性,并提出了相應(yīng)的響應(yīng)策略。算例仿真表明,該技術(shù)可以在負(fù)荷側(cè)響應(yīng)電網(wǎng)頻率緊急狀態(tài),從而減少直流閉鎖等故障下負(fù)荷的切除量,有效提高電網(wǎng)頻率的穩(wěn)定性。

    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
