摘要
随着电力电子和控制技术的飞速发展,大型电池储能电站发展成为保证电力系统可靠供电的一个重要手段,而大型储能电站的保护则是电站安全可靠运行的哨兵。在分析储能电站基本网架的基础上,提出了储能电站的保护分区,并根据各分区电气设备的特点,详细分析了分区的保护配置原则和配置方案。最后讨论了各分区保护间的配合,以使保护间具有很好的协调性,保证储能电站在各种保护的配合工作下,能够安全可靠运行,为电力系统调峰、故障提供有效支援。
With the rapid development of advanced power electronic and control technology, bulk battery energy storage plant gradually becomes a means of ensuring power system reliability and safety; however, protective relaying is very important for its reliability and safety operation. In this paper, a zone of protection is put forward on the basis of the fundamental architecture of the plant and then the basic configuration schemes and principles of different protection zones are analyzed according to the characteristics of electric equipments in each zone. At last, the coordination of the protections in different zones is discussed in order to ensure the safety and reliability operation of bulk battery energy storage plant. Battery storage plants which operate normally are able to provide effective support for power system when a peak load or fault occurs.
