摘要: 随着新型电力系统的逐步构建，高比例新能源和高比例电力电子设备的大量接入对电力系统仿真技术提出了更高的要求。电力系统全电磁暂态数字仿真逐渐成为大电网仿真分析的主要手段，而仿真精度直接影响到电网的安全稳定运行。本文从静态和动态两个角度考虑，利用平均百分比误差计算残差相似度，利用标准系数法计算形状相似度，提出了综合以上两个相似度指标的仿真精度评估方法。并在ADPSS平台上针对2020年华东“9·27”故障进行了华东电网全电磁暂态建模仿真和故障反演，对比了±1100 kV昌吉–古泉特高压直流输电系统的实测数据及仿真结果，进行了算例分析，验证了该评估方法的有效性。
Abstract: With the gradual construction of new power system, higher requirements for power system simulation technology have been presented for the large-scale access of high-proportion new energy and high-proportion power electronic equipment. The full-electromagnetic transient digital simulation in power system has been used as the main means of large power grid simulation analysis step by step, and the simulation accuracy has great effects on the safe and stable operation of power grid. In this paper, from the static and dynamic perspectives, the average percentage error is used to calcu-late the residual similarity, and the coefficient method is used to calculate the shape similarity. A simulation accuracy evaluation method concerning the above two similarity indexes is proposed. The full-electromagnetic transient modeling simulation and fault inversion of East China Power Grid are carried out on the ADPSS platform for the “9·27”’ fault in 2020 in East China power grid. The measured data and simulation results of the ±1100 kV Changji-Guquan UHVDC transmission system have been compared, and the example analysis was made, which proved the effectiveness of the evaluation method.
