摘　　要：基于黑启动试验实测数据对潮流仿真结果进行了验证,对输电线路参数不精确引起的节点电压和无功功率的误差进行了分析;比较了变电站启动负荷、火电厂启动辅机和火电机组并网仿真结果与实测数据,从系统建模和仿真条件两方面对动态仿真的准确性进行了分析。分析认为:建立的黑启动试验系统模型足够准确,能够正确模拟黑启动试验过程中各类元件的动态特性,对大部分操作的仿真条件预测与实际相符,可为黑启动试验系统的电压、频率等指标提供准确的数值边界和发展趋势预测。The power flow simulation results are verified based on the measured data of black start test,and the errors of node voltage and reactive power caused by inaccurate transmission line parameters are analyzed.The simulation results of substation start⁃up load,thermal power plant start⁃up auxiliaries and thermal power unit grid connection are compared with the measured data,and the accuracy of dynamic simulation is analyzed from two aspects of system modeling and simulation conditions.Finally,it is concluded that the established black start test system model is accurate enough to correctly simulate the dynamic characteristics of various components in the process of black start test.The simulation condition prediction of most operations is consistent with the reality,which provides an accurate numerical boundary and development trend for the voltage,frequency and other indexes of the black start test system.
