摘要
在电力系统发电厂和变电所内,蓄电池组性能好坏,很大程度决定了直流操作电源的可靠性,合理使用和维护蓄电池,使之保持在良好的运行状态,这是延长蓄电池寿命和提高直流操作电源可靠性的关键。在分析了电力系统蓄电池放电重要性和当前蓄电池放电装置现状的基础上,结合蓄电池放电的基本要求,设计出了一种新型的正弦波逆变蓄电池回馈放电装置,该装置包括DC/DC变换电路、PWM整流逆变电路、控制电路、保护电路等,同时也对放电装置的工作原理进行了详细的阐述。
In power system plants and substations, the reliability of DC operating power is largely decided by the storage battery performance. Reasonable use and maintenance of batteries are the key to extend battery life and improve the reliability of DC operation power. This paper analyses the importance of storage battery discharge in electric system and present situation of storage battery discharge device. On this basis, combined with basic demand of storage battery discharge, a new type feed-back discharge device with sine wave inverter for storage battery is designed. This device includes DC/DC transformation circuit, PWM rectifier and inverter circuit, control circuit, protection circuit, etc. This paper also expounds the operation principle of this discharge device in detail.
