| 摘 要： | 结合油田配电网普遍存在功率因数低、网损及谐波污染严重的现象,针对固定无功补偿存在的缺陷,本文将无功动态补偿及谐波抑制技术应用于油田配电网低压集中无功补偿系统中,利用实时检测得到的系统无功需求量控制固态继电器分组投切电容器,实现了无功功率的“按需”补偿;通过串联电抗器的方法有效抑制了谐波放大,获得较好的补偿效果。测试结果表明,该方式经济稳定,节电效果明显。

| Abstract: | In order to overcome the disadvantage of fixed reactive compensation to raise the power factor,lower the line loss and suppress harmonic in oil-fi eld power distribution network,the dynamic reactive compensa tion and harmonic suppression technology to the low-voltage reactive compensati on in oil-field power distribution network are applied.The amount of the rea ctive power real-time measured in the system controls the solid state relay to switch the capacity-units,the amount of compensation fit for the demand in t he system to improve the effect of compensation.And the series reactor co uld suppress the harmonic.The fact proves that this method is economical and credible. |
