Abstract

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.

利用可充电电池系统维持电能质量的控制评价

像氧化还原流这样不因频繁充放电而老化的可充电电池，具有相当于中小企业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为350 /spl mu/s，最大过载率为4.6次。这些系统有利于实现从旋转储备到经济负荷调度的宽频段电力控制，也可用于均衡负荷和保持电能质量。利用该系统对电气化铁路的动态稳定性、闪变、电压跌落和充放电再生功率进行瞬时控制是有效的。利用氧化还原液流电池快速响应和过载能力的特点，通过动态仿真，从物理上阐明了氧化还原液流电池的化学反应特性和二次控制的效果。充电/放电周期越短，电池效率越高。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。
