摘 要:中心控制室(CCR)是大型炼化企业中的关键设施。按规范的要求保障对CCR可靠供电的同时,还需要对CCR失去全部外部电源后,对装置生产运行的影响程度进行分析,以确保生产安全。通常应采取多种方案,确保CCR内一级负荷中特别重要负荷的不间断供电。文中提出了保证重要负荷的不间断供电的3种方案,并比较其技术和经济性,从中确定最优方案。CCR is the key facility in the large-size oil refining and chemical company. In order to ensure production safety and avoid economic loss,the influence degree should be considered and analyzed when CCR loses all of its external power supply at the same time, even if reliable power supply of CCR has already be designed in engineering according to standards and codes. In some cases, the sources of CCR's external power supply and the power supply time of backup battery in electric source for safety service will bring certain security risks when CCR loses all of its external power supplies. Therefore, some necessary measures should be taken to keep the vital load of the first level load in CCR running under the uninterrupted power supply. Three schemes are listed as follow, namely, to add the third power supply, extend the power supply time of backup battery in electric source for safety service and add diesel generating sets. Technical and economic comparison should be used as a method to determine the optimal solution.
