摘　　要：为了深入研究锦苏特高压直流接入后江苏电网的运行特性,交流系统故障或者双极闭锁等故障对江苏电网造成的影响,基于2013年江苏电网预计夏高负荷,在电力系统全数字实时仿真装置(ADPSS)平台上搭建了锦苏特高压直流输电系统的电磁暂态模型和江苏电网其余部分的机电模型。通过机电—电磁混合典型故障仿真研究了锦苏直流接入对江苏电网稳定性的影响,分析了锦苏直流接入对江苏电网静态稳定电压极限的影响,研究了双极闭锁再启动的过程。结果表明,该模型能准确反映锦苏直流输电系统的实际运行特性;锦苏直流的接入提高了苏南地区和关键线路的静态电压稳定极限;通过采取适当措施,直流双极闭锁和交流系统典型故障下江苏电网能够维持稳定运行;双极闭锁后江苏电网能够顺利启动。In order to research the operating characteristics of Jiangsu power grid with Jin-Su UHVDC accessing, and the influence on Jiangsu power grid after AC system failure or bipolar blocking, based on higher load in summer of Jiangsu power grid, the Jin-Su UHVDC transmission electromagnetic transient model and the electromechanical model of remaining Jiangsu power grid on ADPSS （power system digital simulation device）are built up. The stability of Jiangsu power grid with Jin-Su UHVDC accessing by electrical-electromagnetic hybrid typical fault simulation is studied and the impact on stability margin of Jiangsu power grid with Jin-Su UHDVC accessing is analyzed. The restart process after bipolar blocking is also researched. Simulation and experimental results show that the model can accurately reflect operating characteristic of UHVDC transmission from Jinping to southern Jiangsu; south of Jiangsu area and key line static voltage stability limit can be promoted by accessing UHDVC transmission from Jinping to southern Jiangsu; Jiangsu power grid can operate stately during bipolar blocking or typical fault in AC system; Jiangsu power grid can restart smoothly after bipolar blocking.
