摘　　要：云南至广东±800kV直流输电工程是世界上首个特高压直流输电工程,对该工程调试过程中的交直流侧滤波器、交流侧换流变压器过电压测试技术和调试经验进行总结,从调试项目的设置、调试方法和验收标准等方面,对该工程与±500kV直流输电工程在站调试和系统调试中的过电压测试技术进行分析比较,指出调试中应注意的问题,提出进一步优化和细化调试安全管理模式、大幅缩短试运行时间等建议。± 800 kV DC transmission project from Yunan to Guangdong is the first UHV DC transmission project in the world, in the commissioning process of which, over-voltage test technology and commissioning experience of filters at both AC and DC sides and converter transformer at AC side are summarized. Over-voltage test technologies between station commissioning and system commissioning of the project and ± 500 kV DC transmission project are comparatively analyzed in re- spect of setting of commissioning project, commissioning method and acceptance standards. Attentions in commissioning are indicated and suggestions such as further optimization and division of commissioning safety management mode and drastic shortening of time of test run are made.
