摘要
本文以某220kV变电站并联电容器组(串联4.5％电抗器)对3次谐波的严重放大为例,探讨了当串联电抗器电抗率为4.5％或6％时,电容器组分组容量与3次谐波放大的关系。并提出以谐波电压放大曲线确定电容器分组容量的要求。
In a 220kv substation with groups of parallel capacitors (with 4.5% reactor in series), the 3rd harmonics were seriously enlarged. Taking this as an example* this paper presents the relation between 3rd harmonic enlargement and grouped capacity of capacitors which has a 4.5- 6 % series reactor. Harmonic voltage enlargement curve and criteria for determinig grouped capacity are also presented.
