摘　　要：通过公式计算分析了柴油发电机组空载启动时电动机所引起的发电机出口电压降比有载启动时严重的原因，明确了黑启动时最大电动机投入时只需进行空载电压降计算即可。通过对启动电动机启动功率的分析，提出以柴油机的制动功率必须大于负荷的峰值功率作为条件来校验其容量。Through calculation with the formula, the reason was analyzed that the generator outlet voltage drop caused by the motor in the idle start of the diesel generator is more serious than the load start - up. The author indicates that only calculation of the idle voltage drop is needed for the input of the maximum motor during the black start. Through analysis on the start power of the starting motor he also puts forward the capacity of the diesel should be checked in conditions that the braking power of the diesel must be larger than the load peak power.
