阀塔寄生参数和子模块等效阻抗对预充电MMC均压特性的影响

Gaoya dianqi
针对模块化多电平换流器在预充电过程中，子模块电容电压均压效果劣化问题，基于换流器不控整流充电过程中子模块电容电压的均衡特性，建立了包含子模块取能电源等效阻抗、阀塔寄生电容和水路电阻的子模块级精细化阀塔仿真模型。计算了不同参数下子模块的不均压度，分析了取能电源功率分散性、均压电阻精度、水路电导率对子模块均压效果的影响机理。研究发现，子模块的参数差异性导致的充电电流不同和阀塔寄生参数导致的对地电流，是造成预充电时子模块均压效果劣化的主要因素，均压电阻可为电荷提供泄放路径 ...

阻容均压方式下双断口真空断路器预击穿特性研究

Gaoya dianqi
双断口真空断路器能够充分利用短真空间隙的优异绝缘性能，显著降低容性电流开合过程中的重击穿概率，提高投切电容器组的性能。文中通过实验研究了双断口真空断路器采用阻容均压方式时的预击穿特性，包括预击穿电压、预击穿开距及其分散性，并计算其威布尔分布。研究结果表明，无论电压幅值如何，高压电阻都可以通过阻断从均压电容流向真空灭弧室的放电电流来延缓击穿过程，显著提升了双断口真空断路器的预击穿特性。对于串联电阻和桥接电阻两种阻容均压方式，桥接电阻可以减少电路中使用的电阻数量，降低断路器成本和体积 ...
