摘　　要：发电企业在大面积停电后的系统自恢复通俗地称为黑启动。黑启动的目的是要在最短的时间内是使电网恢复带负荷的能力,并恢复电网运行,本文介绍了交流不间断电源黑启动功能的工作原理,从黑启动电阻元件的原理、选择与计算出发,详细分析了选择黑启动电阻的理论依据,提出了选择黑启动电阻的具体方法。在此基础上,针对选定的黑启动电阻进行了黑启动实验。通过实验结果表明,采用本文提出的方法选择的黑启动电阻能使不间断电源获得最佳的黑启动特性。After a large area of power outage,the system of power generation enterprises is called the black start. Black start to in the shortest period of time is to make the power recovery capacity with load, and the restoration of the power grid, this paper introduces the working principle of AC uninterruptible power system black start function, from the selection principle, black start resistance element and calculation of the detailed analysis of the theoretical basis for the selection of black start resistance and put forward specific methods of black start resistance. On this basis, the black start resistance experiment was carried out for the selected black start resistance. The experimental results show that the black start resistor selected by the method proposed in this paper can make the uninterrupted power obtain the best black start characteristic.
