摘要
超级电容器具有适应温度范围广、维护简单、浮充寿命长、供能稳定及低污染等优点,适合作为配电自动化系统后备电源。针对超级电容器在配电网中的应用实例,对不同运行年限及运行环境的超级电容器电容值、剩余容量、内阻等指标进行了分析,验证了超级电容器在免维护或低维护状态下作为配电自动化设备备用电源的优越性和可行性。
It is considered that the super capacitor has the advantages of wide temperature range, easy maintaining, long floating charge life, stable energy supply and low pollution, which is suitable to be used as the backup power supply of distribution automation system. Aiming at the application example of super capacitor in distribution network, the indexes of super capacitors such as capacitance value, residual capacity and internal resistance in different operation years and environment are analyzed, and the superiority and feasibility of super capacitor as standby power supply of distribution automation equipment in maintenance free or low maintenance state are verified.
