| 摘 要： | 模块化多电平电压源型换流器作为柔性环网控制器和统一潮流控制器(UPFC)系统中的关键设备,其运行的可靠性直接影响到整个系统的安全稳定运行。文中以应用于柔性环网控制器及苏南500 k V UPFC工程的换流阀作为研究对象,采用PTC Creo 3D与Ansys混合建模技术,建立了换流阀塔的三维模型,详细计算了换流阀塔在绝缘型式试验下的电场分布。计算结果表明:换流阀塔对地空气间隙、层间空气间隙以及换流阀塔的外表面的空气介质等绝缘强度都能满足换流阀绝缘型式试验的要求,保证换流阀的安全可靠运行。

| Abstract: | As the key equipment in the flexible looped network controller and UPFC,the reliability of the modular multilevel voltage sourced converter directly affects the safe and stable operation of the whole AC system.We established a 3-D model of the flexible looped network controller and Sunan 500 kV UPFC converter using PTC CREO and ANSYS.We calculated the electric field distribution of the converter valve in insulation type test.The results show that the insulation strength of the air gap distance to the ground of converter valve,the air gap between layers of converter valve,the air medium outside of converter valve can meet the requirements of the converter valve in insulation type test,which can ensure safe and reliable operation of the converter valve. |
