摘要
直流电网逐渐成为分布式电源接入的有效方式,储能是平抑直流供电系统电压波动的最直接手段。分析了典型含分布式电源的直流供电系统网压波动产生机理,对比了高速飞轮和低速飞轮在快速抑制网压波动方面的动态特性差异,给出了GTR高速飞轮储能针对独立直流供电系统的电压波动抑制应用方式。最后,对所提飞轮储能装置进行了高转速状态下的充放电实验,结果显示高速运行时的飞轮充放电效果良好。
DC power grid has gradually become an effective way to connect distributed power sources,and energy storage is the most direct way to stabilize the voltage fluctuation of DC power supply system.The generation mechanism of voltage fluctuation in a typical DC power supply system with distributed generation is analyzed,the dynamic characteristics of high-speed flywheel and low-speed flywheel in the rapid suppression of voltage fluctuation are compared,and the application scheme of GTR high-speed flywheel energy storage for voltage fluctuation suppression of independent DC power supply system is presented.Finally,the charging and discharging experiments of the flywheel energy storage device at high speed are carried out,and the results meet the expectations.
