摘要
与电解铝负荷相关的N-2故障可能导致电网的安全稳定问题,若稳控系统对电解铝全厂负荷进行切除,易造成较大的经济损失和电力安全事故。文中通过对电解铝整流机组的控制方式和特性进行分析,结合稳控系统控制要求提出了一种新的稳控切负荷方法,可实现对电解铝生产的部分负荷进行切除,并通过算例分析了可行性。
The N-2 fault associated with the electrolytic aluminum load may lead to the security and stability problem of the power grid.It is easy to cause large economic loss and electric power safety accident after tripped the whole load of electrolytic aluminum plant.Based on the analysis of control mode and characteristic of electrolytic aluminum rectifier unit and requirements of the stable control system,a new stable control method is proposed,which can be used to shed partial load of the electrolytic aluminum production,and the feasibility is analyzed by an example.
