The Research And Improvement Of DC System's Reliability In Qingdao Power Plant

The hidden troubles of DC system's operation in Qingdao electric power plant which influences the security of power supply are mainly analyzed in this paper. According to the demands, we improve the DC charger, monitor the storage battery, and put forward a new block supply idea with DC system and put the scheme into practice. This scheme have solved the hidden troubles in DC system which brought by the mode of connection and the imperfect operating monitor of the storage battery. Especially the implementation of the block supply scheme by DC system, the long-term difficult problem in the field is solved. The unsafe factors in the long-run DC system are settled. It has made better economic benefit and social benefit, it is worthy to be popularized in the field.
