摘要
从分析电气化铁道采用的固定无功补偿装置无法在山区提高牵引变电所的平均功率因数和接触网电压水平出发,对微机控制晶闸管开关型静止动态无功补偿系统的构成、功能特点、工作原理等方面进行了阐述,并结合应用实例作了分析,验证了采用该系统可以快捷、高效、可靠地提高功率因数和接触网电压水平。
On basis of analysis of the impossibility to raise average power factor in traction substation by fixed reactive compensation equipment applied in electrified railways and with consideration of OCS voltage, illustrates the composition, function characteristics and working principles of computer-controlled thyristor standstill and dynamic reactive compensation system, implements the analysis with reference of their practices, it is verified that the application of the system is possible to raise power factor and OCS voltage quickly and reliably.
