摘要
Abstract
In allusion to the situation of high requirement for consistency of taking series structure of lithium batteries in 110 kV substation DC system as backup power source, this paper discusses parallel structure of lithium batteries and proposes to use Boost converter and take advantage of battery remaining capacity to dynamically adjust duty cycle.Meanwhile, on the basis of combining load condition of the DC system in 110 kV substation, it calculates and chooses lithium battery capacity according to relevant regulations and actual discharging characteristic of lithium batteries.By using MATLAB/Simulink software, it conducts real-time simulation detection on service condition of the backup power source.Simulation results indicate that output voltage parameters of lithium batteries worked out by this scheme are in compliance to design requirements and in cases of insufficiency of battery remaining capacity and so on, this scheme can realize uninterruptible replacement for lithium batteries.关键词
