| 摘 要： | 云南-广东特高压直流嵌入交流系统运行，将使送端云南电网面临诸多挑战。文章首先介绍送端云南电网的特点，然后应用电磁暂态仿真程序PSCAD/EMTDC对2010年云广特高压直流送端的谐波不稳定问题进行研究。进行了频率扫描分析、故障激发试验和谐波注入分析，仿真结果表明，除极个别运行方式外，系统不存在发生谐波不稳定的可能。

| Abstract: | The UHVDC power transmission project from Yunnan to Guangdong is embedded into AC system,so the Yunnan power grid at the sending end will face with challenges.The authors present the features of Yunnan power grid,then by using electromagnetic simulation program PSCAD/EMTDC,the harmonic instability problem at the sending end of this UHVDC project in the year of 2010 is researched.By means of frequency scanning analysis,fault provocative test and harmonic injection test,simulation results show that except the very individual operation condition,it is impossible to occur harmonic instability in this UHVDC project. |
