摘要
为了保证电气化铁道牵引供电系统的功率因数、负序、网压和谐波符合国家规定的标准,以往的做法是在牵引供电系统中采取各种方式或装置分别进行补偿。本文提出采用一种可分相控制的SVC来实现综合补偿,并论证了它的可行性和优越性。
In order to ensure that the data of power factor, negative sequence and harmonic of traction current meet the national standards, and to improve the voltage level in traction network as well, a common practice is to take a series of methods or devices in sub-station to compensate different parameters individually. In this paper, a complex compensation scheme with phase controlled SVC is suggested, and a feasibility and superiority is discussed.
