500 kV新型防雷绝缘子仿真与试验分析

Dianci bileiqi
提高输电线路防雷能力，常采取安装避雷器和降低接地网接地电阻的方法，但前者安装维护难度大，后者经济性较差。为此，文中提出一种利用500 kV新型防雷绝缘子提高线路防雷能力的方法。该新型绝缘子经带环形ZnO电阻片的穿心结构避雷器与普通绝缘子串联进行实现。本研究通过ATP-EMTP软件搭建500 kV输电线路模型，对比分析安装新型防雷绝缘子和普通绝缘子线路，遭受反击、绕击时的过电压波特点。同时，通过雷电冲击闪络、操作冲击的现场试验对其防雷能力进行了充分验证。仿真和试验结果表明：线路遭受雷击时 ...

低电压穿越场景下的构网型储能变换器功率协同控制策略

Gaoya dianqi
随着高比例新能源并网，构网型储能变换器在网侧电压故障期间，面临着暂态失稳和过电流的问题，对并网稳定造成严重威胁。针对这一问题该文首先建立不同工况下的暂态模型，分析了暂态功角失稳和过电流的原因。其次，在此基础上提出了面向低电压穿越场景下的有功—无功协同控制策略，通过电压跌落的在线辨识，结合输出侧相量关系，实现了对构网控制策略参考功率的分段自适应控制。最后，通过仿真和实验验证了所提方法对提升暂态稳定性、无功支撑及过电流抑制的有效性。
