摘要

直流支撑电容器作为储能元件

应用于柔性直流输电中时

主要起电压支撑、谐波滤波等作用

持续承受直流叠加纹波电压以及高峰值电流作用。本文以厚度6μm的聚丙烯膜为例

研究了直流叠加谐波作用时谐波次数和方阻对薄膜的击穿和自愈性能的影响

研究结果表明

当谐波电压为100 Vrms

次数为1～5次时

谐波次数对薄膜的击穿电压无影响;击穿基本发生在交流电压正半波峰值及其附近。方阻增大

击穿电压增大

自愈能量减小

且均存在饱和的趋势。进一步

提出了直流支撑电容器用薄膜参数设计的建议。

Abstract

DC-link capacitor

as the charging element in the flexible DC power transmission

is used for voltage support and harmonic filtering etc.

and for withstanding continuously DC stacking ripple voltage and high peak current.In this paper

the polypropylene film with thickness of 6 μm is taken as an example to study mainly the effect of harmonic order and sheet resistance on the breakdown and self-healing properties of film. It is shown by the test result that when the harmonic voltage is 100 Vrms and the order is 1～5

the harmonic order has no effect on the breakdown voltage of the film and the breakdown is basically occurred at and around the positive half-wave peak of the AC voltage. The bigger the sheet resistance is

the bigger the breakdown voltage is and the less the self-healing energy is and the saturation tendency is existed. Finally

suggestion on the design of film parameters of the DC-link capacitors is proposed further.
