对榆林炼油厂180万吨/年催化裂化装置工艺管道试压的技术探讨

榆林炼油厂180万吨/年催化裂化装置工艺管道安装总量为39222米,其中碳钢管33796米,不锈钢管道1000米,合金钢管道4426米。该装置工艺管道系统工作介质多、试压系统大、管线跨区域多。在装置4月初开始工艺管道系统试压工作以来,用了不到一个月时间将试压工作顺利完成,给装置保质保量的按期中交夯实了坚定的基础。在整个催化装置工艺管道试压过程中,严格的按照工艺管道压力试验试压包机制进行,建立了一个有序、严密、高效的试压程序。

A Study on the Testing Procedures of IEC 61850 Based Transformer Protective lED

Korea Electric Power Corporation in charge of the power IT project ＂Development of Prototype for Advanced Substation Automation System based on the Digital Control Technology＂, is performing the verification of performance of the substation automation system based on IEC 61850. In order to verify a transformer protective lED that might be operating in substation automation system, the new standardized document and procedures are required in the aspect of the utility like KEPCO. But there is nothing to describe systematically how to verify IEC 6 1850 based lED in the system environment except an individual IED testing way. This paper will present the substation automation system based ways and procedures to verify the protective function of the IED using UML （Unified Modeling Language）.
