上海电网黑启动方案中采用闸北燃机作为黑启动电源,为确保全黑情况下上海电网的成功恢复,必须解决燃机启动电源的配置问题。在燃机启动电动机负载特性试验的基础上,利用电动机启动瞬间的等值电路,提出了启动电源容量选择的方法,分析了影响启动容量选择的相关因素,并计算了闸北燃机的启动电源容量。 Shanghai Power Grid Black Start program using Zhabei gas turbine as a black start power, in order to ensure the successful recovery of the Shanghai grid under all black conditions, the configuration of the gas turbine start-up power must be solved. Based on the experiment of load characteristic of starting motor, the method of starting capacity selection was put forward based on the equivalent circuit of instantaneous starting of motor. The relevant factors that affect the selection of starting capacity were analyzed. The startup power capacity .
