负载率是衡量电力系统安全稳定运行的重要指标,为了降低供电线路发生故障的概率,提出了电力系统中供电线路负载率的计算方法.利用数字孪生技术映射处理供电线路负载信号的高低时频域;利用电力系统中供电线路的各个节点能量,计算供电线路负载信号的谱熵值,提取供电线路负载信号特征.当供电线路在正常状态下运行时,采集供电线路的负载数据,实现供电线路的负载率计算.实例结果表明:该方法可以计算出供电线路的负载率,并将计算误差控制在10%以内.
Research on calculation method of load rate of power supply line in power system
Load rate is an important index to measure the safe and stable operation of the power system.In order to reduce the probability of power supply line failure,the calculation method of power supply line load rate in the power system is proposed.Digital twinning technology is used to map and process the high and low time-frequency domain of the power supply line load sig-nal,and the spectral entropy value and characteristics of the power supply line load signal are calculated by using the energy of each node of the power supply line in power system.When the power supply line is running in a normal state,the load data of the power supply line is collected to realize the load rate calculation of the power supply line.The example results show that the load rate of the power supply line can be calculated by the method in this paper,and the calculation error is controlled within 10%.
