摘要
某电弧炉钢厂设备改造之后,由于总线供电容量不足引发了电压与功率偏差问题。为解决该问题厂方决定接入分布式电源。通过仿真方法对分布式电源接入后对电弧炉供电运行影响进行了分析,得出分布式电源接入后能有效抬升馈线电压并且提高电弧炉的运行功率水平。当接入35 kV母线上的分布式电源单相容量超过15 MVA时,可以解决该钢厂的供电容量不足引发的问题。
After the equipment transformation of an electric arc furnace steel plant, the voltage and power deviation problems were caused due to insufficient bus power supply capacity. To solve this problem, the factory decided to connect to Distributed Generation(DG). The simulation method is used to analyze the influence of DG on the operation of electric arc furnace power supply, and it is concluded that the DG can effectively raise the feeder voltage and increase the operating power level of the electric arc furnace. When the single-phase capacity of the DG connected to the 35 kV bus exceeds 15 MVA, the problem caused by the insufficient power supply capacity of the steel plant can be solved.
