摘　　要：现有变电站一键顺控功能离线测试时,没有分析变电站并行效果,导致离线测试效果差,提出基于潮流计算的变电站一键顺控功能离线测试研究方法。通过一键顺控技术和其拓扑结构,构建一键顺控系统,引入潮流算法,分析变电站并行度,结合雅可比逆矩阵修正算法,完成变电站系统的并行效果分析,实现变电站一键顺控功能的离线测试。实验表明,设计方法准确获取了静态和动态功耗电流等,变电站数据量为9000个时,其值分别为131 mA和133 mA,确定了工作频率与电流值有关,因此,该方法可以实现变电站一键顺控功能离线测试,具备有效性。In off-line test of one-key sequential control function of substation,the parallel effect of substation is not analyzed,which leads to poor off-line test effect.Based on the one-button sequential control technology and its topological structure,the one-button sequential control system is constructed,the power flow algorithm is introduced to analyze the substation parallelism,and the parallel effect of the substation system is analyzed by combining the Jacobian inverse matrix correction algorithm,and the offline test of the one-button sequential control function of the substation is realized.The experimental results show that the static and dynamic power consumption current can be accurately obtained by the design method.When the data amount of the substation is 9000,the value is 131 mA and 133 mA respectively.It is determined that the working frequency is related to the current value.
