【摘要】：为充分利用众多的氧化铝生产企业的分解槽循环水系统中存在的大量余能,并为其他类似余能回收提供技术支持,研究了氧化铝分解槽循环水系统中余能的特点.根据余能的多少,提出了不同的余能利用方案.重点研究了余能发电的利用方式.并针对余能发电的特殊性,设计了分解槽水循环系统余能发电装置——集成循环水余能发电装置.针对其循环水不能异常中断的问题,提出了循环水保护方案.针对通过机组的水量小于其空载流量时,水轮发电机会在并网条件下吸收电网功率的逆送电情况,提出了发电机逆功率保护方案,并将余能发电装置的控制保护各子系统集成在一起,形成具有励磁、调速、同期和保护功能的"四合一综合控制盘".实践证明,氧化铝分解槽循环水余能发电装置能安全、可靠、稳定运行.
[Abstract]:In order to make full use of the large amount of residual energy in the circulating water system of decomposition tank in many alumina production enterprises, and to provide technical support for other similar waste energy recovery, the characteristics of residual energy in the recycling water system of alumina decomposing tank were studied. According to the number of complementary energy, different schemes of complementary energy utilization are put forward. The utilization mode of residual energy generation is mainly studied. According to the particularity of residual energy generation, an integrated recycling water waste energy generator is designed. Aiming at the problem that the circulating water can not be interrupted, the protection scheme of circulating water is put forward. In view of the situation that the turbine generator absorbs the power of the grid when the water quantity of the unit is less than its no-load flow, a scheme of generator inverse power protection is put forward. The control and protection subsystems of the auxiliary power generation device are integrated together to form a "four-in-one integrated control panel" with the functions of excitation, speed regulation, synchronization and protection. The practice shows that the residual energy generator of circulating water in alumina decomposing tank can operate safely, reliably and stably.
