摘要
针对常规站用电系统在可靠性与自动化功能方面的不足,提出了一种基于四段母线供电的站用电系统设计方法。该方法将重要负荷与非重要负荷分段设置,增强了投切的灵活性,保证了重要负荷在各种工况下均能正常运行。同时,通过失压脱扣与电气闭锁控制开关开合,无需手动操作,智能化程度更高。该设计方法已在多个海外工程项目中成功实践运行。
Regarding on the shortcomings of conventional station power systems in terms of reliability and automation functions,a quad-busbar-based optimized auxiliary power system is proposed.This method puts the important and non-important loads in different sections,which enhances the flexibility of switching and ensures normal operation of important loads under various working conditions.Moreover,the circuit breakers can opened and closed through voltage loss tripping and electrical locking control without manual operation,which has higher degree of intelligence.This design method has been successfully applied in multiple overseas engineering projects.
