涌流抑制装置在换流站中的应用
|
摘要
在电力系统中,投切电容器或者空载投入变压器时会产生涌流,将对设备产生不良影响或引起保护误动作,而涌流抑制器通过选择合适的投切角度能有效削减涌流。介绍了涌流抑制器的基本原理,并结合换流站监控系统不同技术路线分析了其在高压换流站中的应用情况。
In power system, inrush current will appear while closing /opening breakers of capacitor or closing a no-load transformer. The inrush current may cause protection device an incorrect action or harmful effect to primary equipment. By closing/opening breakers at an appropriate phase angle, the inrush current suppression device can reduce the inrush current effectively. In this paper, the basic principle of inrush current suppression device was introduced, and the application of the device based on different technology road of the station monitoring system was analyzed.
