Theoretical research and simulation of series compensation technology of distribution line

As known to all, two major parts will lead to Circuitous voltage loss, one is the line resistance, the other is the line reactance. Due to the high voltage distribution lines with long distance transmission and big wire section, wire reactance is much bigger than the line resistance. Therefore, the research on the lower voltage drop loss of line reactance is present hot topic. Some network 66kV system has some problems such as the levels of voltage along the loads are low and the loss along the line is big due to the long distance and the huge reactance, aiming at the problems, discusses of series compensation technology are made in the paper. Through the theoretical analysis and simulation, the feasibility of the technology of improving the voltage quality in distribution network is proved. To improve power quality, reduce the line loss, ensure the safe and stable operation of distribution networks, a new thought is put forward.
