摘　　要：随着特高压输电工程的建设,青海、西藏等地区建设特高压交直流工程可将风、光等可再生资源优势转化为电力能源,并向东、中部负荷中心输送,可有效缓解中国电力能源区域分布不均衡的问题。为了满足青海、西藏等高海拔地区特高压输电工程现场试验的需要,文中研制了国内首套1 500 kV高海拔试验用交流串联谐振试验系统,根据现场特殊环境工况,对整体系统组成进行了论述,对其中的关键部件串联电抗器进行了电场仿真计算。结果表明文中所研制的试验系统在1 500 kV运行时电晕放电量小于10 pC,可满足高海拔地区对特高压设备进行交流耐压及局部放电测量时使用。With the construction of UHV transmission project the construction of UHV AC and DC projects in Qinghai Tibet and other regions can transform the advantages of renewable resources such as wind and solar energy into electric energy and transport them to the load centers in the east and middle which can effectively alleviate electric energy distribution problem in China.In order to meet the needs of field test of UHV transmission project in high altitude areas such as Qinghai and Tibet this paper developed the first 1 500 kV AC series resonance test system for high altitude test in China.According to the special environmental conditions at the site the overall system composition was discussed.The electric field simulation calculation was performed on the key component series reactor.The results show that the test system developed in this paper has a corona discharge of less than 10 pC at 1 500 kV which can be used to measure AC withstand voltage and partial discharge of UHV equipment in high altitude areas.
