燃机启动电源配置方案的研究

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.

Configuration Schemes of starting power sources for gas turbines

In the black start scheme for Shanghai Power Grid,the gas turbines in Zhabei Power Plant were selected as the black start power source.To ensure successful restoration of Shanghai Power Grid in blackouts,the problem of starting power source configuration for the gas turbines must be solved.Based on the load characteristic tests for the starting motor of the gas turbine,the method for selecting the capacity of the starting power source was created by u- sing the motor's equivalent circuit during the instant period of starting.Relevant factors influencing selection of the starting capacity are analyzed,and the starting power source capacity of Zhabei gas turbines are calculated.
