| 摘要: |
| 对风光储电站黑启动的试验过程中风机并网过程进行了分析。首先，重点分析了风机启动造成储能变流器跳闸的原因，并对风机参与黑启动的过程进行了仿真验证，指出由于风机缺少恰当的软启动过程，导致启动过电流，使得黑启动失败；然后，提出了风机参与黑启动过程中直流电压软启动的控制策略；最后，通过仿真对所提控制策略进行了验证，表明所提方法能够很好地避免风机变流器的启动过电流问题。 |

| Abstract: |
| The grid-connection process of wind turbine during the black-start of a wind/photovoltaic/energy-storage station is analyzed. The cause of energy-storage converter trip due to the wind turbine startup is emphatically analyzed and the black-start process with wind turbine is simulated, which verifies that, the wind turbine startup overcurrent due to the lack of proper soft-startup process results in the black-start failure. The control strategy for the soft-startup of DC voltage is proposed for the black-start with wind turbine, which is verified by simulation, showing that the startup overcurrent of wind turbine converter is effectively avoided. |
