摘要
随着电力系统规模的不断扩大,系统内元件日益复杂,紧急控制系统的优化和改进变得尤为重要。为了确保系统的安全稳定运行,提出了一种面向配电系统紧急控制的解列单元定值刷新周期生成方法。对配电系统的负荷情况、电压等参数进行处理分析。在此基础上,提出了采用主成分分析以提取数据集的主成分,并运用灰色关联度分析来计算解列单元定值刷新周期的方法。算例分析表明,所述方法可以适应配电系统运行状态的变化,生成合理的解列单元刷新周期。应用所提方法能够有效提升配电系统紧急控制的实时性与准确性,保障系统的安全可靠运行。
With the continuous expansion of power system,the components within the system are becoming increasingly complex,and the optimization and improvement of emergency control systems have become particularly important.In order to ensure the safe and stable operation of the system,a method for generating the setting value refresh cycle of the spliting unit for emergency control of the power distribution system was proposed.The load situation,voltage and other parameters of the power distribution system were processed and analyzed.On this basis,a method of using principal component analysis to extract the principal components of the dataset and applying grey correlation analysis to calculate the refresh period of the column spliting unit was put forward.The example analysis shows that the method can adapt to changes in the operating status of the distribution system and generate reasonable refresh cycles for the spliting units.The proposed method can effectively improve the real-time and accuracy of emergency control in the power distribution system,ensuring the safe and reliable operation of the system.
