中文摘要：

2008年底国内某2大区域电网先后进行了500kV联网试验和特高压联网试验。为校核互联系统静态和动态仿真模型及参数的正确性、掌握互联电网动态特性，在区域电网公司能量管理系统（energymanagement system，EMS）和广域测量系统（wide area measurement system，WAMS）记录的试验数据基础上，运用电力系统分析综合程序对这2次试验进行了暂态过程仿真研究。基于调整好的稳态方式，通过分析、优化扰动模拟方案、不断修正和调整潮流、调节器参数等措施，使暂态仿真波形与实测波形吻合的较好，成功复现出试验暂态过程，获得了与电网动态特性相一致的仿真模型，为仿真研究互联电网其它内容奠定了基础。

英文摘要：

At the end of the year 2008 the interconnection tests of two domestic large-scale regional power grids by means of 500kV system and 1 000kV system respectively were performed. To check the correctness of static and dynamic models as well as that of model parameters and to master the dynamic characteristics of interconnected power grids, based on the testing data recorded by energy management system （EMS） and wide area measurement system （WAMS） of regional power grid companies, the simulation research on the two tests is carried out by power system analysis software package （PSASP）. Based on well-adjusted steady state and by means of analyzing and optimizing the simulation scheme for disturbances as well as correcting and adjusting power flows and regulator parameters continually, the obtained waveforms from the simulation conform to actually measured waveforms well and the transient process in the tests are successfully reappeared, thus the simulation models that coincide with dynamic characteristics of power grids are attained.
