氧化还原流等可充电电池不会因频繁的充放电而老化，具有与超导储能系统相当的快速响应能力和出色的过载能力。验证了氧化还原液流电池的响应时间和最大过载速率分别为350 /spl mu/s和4.6倍。这些系统有利于实现从旋转备用到经济负荷调度的宽频带功率控制，也可用于均衡负荷和维持电能质量。采用该系统的瞬时控制对电气化铁路的动态稳定、闪变、电压跌落和充放电再生功率的控制是有效的。通过动态仿真，阐明了液流电池的化学反应物理特性，以及利用液流电池响应快、过载能力强的特点进行二次控制的效果。当充电/放电的循环周期变短时，电池效率增加。对这些性能的理解可用于确定最终用户每次使用的最佳可充电电池系统配置。
The rechargeable batteries like redox flow which are not aged by frequent charging/discharging, have a quick response equivalent to SMES and outstanding capability of overload. The response time and the maximum overload rate of redox flow battery are verified as 350 /spl mu/s and 4.6 times. These systems are advantageous for power control under wide frequency band which covers from spinning reserve to economic load dispatching, and also used for leveling load and maintaining power quality. The instantaneous controls using these systems are effective for dynamic stability, flicker, voltage dip and charging/discharging regenerative power of electric railways. The authors clarify the chemical reactive characteristics of the redox flow battery physically and the effect of secondary control utilizing characteristics of quick response and overload capability of the redox flow battery by dynamic simulation. The battery efficiency increases when the cycle period of charging/discharging becomes shorter. The comprehension about these performances can be used to determine the optimum rechargeable battery system configuration for each use of end users.
