摘要
依据可靠性理论中系统平均无故障时间及系统可靠度评估的相关内容,对大容量蓄电池组的不同组合方式进行了可靠性评估。通过实验证明,并串联系统的可靠性要优于串并系统和串并组合系统的可靠性,该结论对动力工程设计及电力系统中的直流系统改造具有指导意义。
According to the reliability theory about the mean time to failure and the system reliability evaluation, the reliability of the high capacity storage battery arrays with different connection schemes was evaluated. It is found that the reliability of the array with parallel-series connection is superior to that with series-parallel connection or the combination of series and parallel connections. The result is significant for the design of power engineering and the reconstruction of PC system in the electrical power system.
