无功补偿装置在散货码头供电系统中的应用

Reactive Power Compensator Applies to Power Supply System of Bulk-cargo Terminal

目前港口大型装卸机械设备属于一种典型的无功源和谐波源。在日常运行过程中,这些设备会产生大量无功功率,并且谐波污染较为严重。传统的无功补偿装置对无功功率反应速度有限,消除谐波效果差。然而静止无功补偿装置(SVG)作为一种新型的无功补偿设备在这两方面都有比较好的治理效果,是现阶段港口供电系统提高电能质量水平的最佳解决方案。

At present, large-scale port handling equipment is a kind of typical device which generates reactive power and harmonic wave. During normal operation, the equipment generates a large amount of reactive power and causes serious harmonic wave pollution. The traditional reactive power compensator responses reactive power slowly,and eliminates little harmonic wave. As a new reactive power compensator, static var generator（SVG） solves the above two difficulties, which is regarded as an optimum option for improving electric energy of harbor power supply.
