    摘 要：廣州電網(wǎng)負荷密集，交直流混聯(lián)運行特性復雜，局部故障引發(fā)大面積停電風險日益凸顯。以恢復重要用戶供電和盡快啟動近區(qū)主力電廠為目標，提出了黑啟動電源布局規(guī)劃的基本原則。給出了表征恢復速度的黑啟動恢復級數(shù)實用化指標，探索了常規(guī)氣電機組、現(xiàn)有機組加裝儲能、煤電機組FCB改造及柔直背靠背互聯(lián)等4 種方式的黑啟動電源規(guī)劃方案，并評估了“十四五”期間廣州電網(wǎng)的黑啟動能力，對指導大型受端城市電網(wǎng)黑啟動電源規(guī)劃具有一定的借鑒意義。

    關鍵詞：黑啟動；電源規(guī)劃；故障恢復級數(shù)

    Abstract: Guangzhou is the larger load center in the power grid, the AC/DC hybrid operation characteristics are complex, and the risk of large-area power outage caused by local fault is increasingly prominent. To restore the power supply of important users and start the main power plants in the near area as soon as possible, the basic principles of black start power planning are proposed. The fault recovery steps index of black is given, representing the recovery speed. Four types of black start power planning schemes are explored, including conventional gas turbine units, existing units with energy storage, FCB transformation of coal-fired power unit and back-to-back VSC HVDC interconnection. The black start capability of Guangzhou Power Grid during the "14th five year plan" period is evaluated, which has certain reference significance for guiding the black start power planning of large receiving end city power grid.

    Key words: black start; power planning; fault recovery steps index
