采用动态无功补偿方式,改善变电所功率因数

To Improve Power Factor of the Substation by Dynamic Reactive Compensation

针对电气化铁路变电所功率因数低 ,不能满足剧烈变化的牵引负荷对无功补偿要求的现状。对无功补偿的原理及方法进行简要阐述 ,根据各供电臂负荷的大小 ,运用自动投切分组的并联电容补偿装置 ,以减少无功量 ,提高变电所的功率因数 。

The power factor for the railway substation of the electrified railway is low and can not meet the conditions of severe tractive load to reactive compensation requirements.The principle of reactive compensation and the method are expounded.According to each supply arm load,use shunt capacitance compensation equipment of automatic switching group to reduce reactive quautity and increase power factor of the substation.Meanwhile,reduce harmonic component of tractive load to pllution of the electric powor system.
