| 摘 要： | 建立准确而有效的换流器数学模型是研究大规模交直流混联系统动态特性的关键问题。分析在交流系统不对称情况下,换流阀导通时刻偏移和三相换相角不平衡的HVDC换流器动态特性。由此,提出基于序分量的适用于各种运行工况及故障的改进换流器动态相量模型,该模型突破了传统换流器动态相量模型的应用局限性。将其应用于贵广Ⅱ回HVDC系统详细模型和CIGRE HVDC系统标准模型的交直流系统动态特性的全面仿真计算,与应用PSCAD/EMTDC电磁暂态仿真软件得到的仿真结果相比较,结果表明该模型准确有效。

| Abstract: | Effective converter modeling is one of the key problems for analyzing the dynamic characteristic of the large-scale AC/DC hybrid power system. The dynamic processes of the HVDC converter is analyzed under the condition of the asymmetric AC system,involving the variation of switching instants and unbalanced commutation overlaps. Then,an advanced dynamic phasor model for the HVDC converter,which is suitable for the normal operating and fault conditions of the system,is established. Based on the Guiguang II HV... |
