摘要：The traditional power design, construction, has been able to meet the requirements, but it has not been established engineering data database support and the correlation between the data is poor, due to inadequate coordination among design professionals, design easily lead to mistakes, field problems, and design results failed in all aspects of the project to be fully utilized. With the technology of three-dimensional integrated design system penetrates in all walks of life, the introduction of three-dimensional integrated design system substation design solutions and the application of common devices of State Grid Corporation in recent years, which provide technical conditions for the application of virtual reality technology in substation design. According to its own characteristics of substation project, we now propose prospect on virtual reality technology in substation design application.

摘要：随着河南省电力输电线路建设规模的发展,必然会有越来越多的输电线路杆塔基础修建在膨胀土地基上,而膨胀土地基由于天然强度低、压缩性高,将对输电线路杆塔基础的抗倾覆稳定性造成巨大隐患。新型加翼桩是在地表以下局部桩体四周设置翼板,以大幅提高基础水平承载力的一种桩基础。由于新型加翼桩尚未大规模投入到工程实践中,对加翼桩在水平荷载作用下的承载力和变形计算还没有统一标准。通过对于膨胀土地基中加翼桩和管桩水平承载特性进行了有限元数值模拟,分析了加翼桩桩顶位移和桩周土体变形模式,从降低桩顶位移和最大弯矩值的角度,以翼板的水平承载力提高系数为指标,给出了翼板的最优化尺寸设计建议。

摘要：某大桥多年来因自然条件堆积较厚海积流动性淤泥,最厚达40m。综合考虑工程地质情况及施工成本,上部结构现浇箱梁设计采用膺架钢管+贝雷支架作为支承承重体系,有效解决地基处理难度大、高支架稳定性差的施工难题,详细阐述膺架钢管+贝雷支架支承施工控制要点及注意事项。

摘要：新能源系统中的蓄电池工作于荒野环境中,其数据远程监测常基于GPRS等无线通信方式实现,这种传输方式需要架设专属基站,成本较高。北斗短报文通讯通过卫星实现数据传输,无需架设基站。基于上述情况设计了一种基于北斗短报文通讯的蓄电池监测系统,系统由监测终端、北斗接收机、远程监测云平台组成。针对数据采集、数据监测与北斗短报文通讯的软硬件需求,给出了对应的设计思路与实现方案。同时考虑到荒野环境对卫星通讯的影响,提出了一种基于数据备份的传输差错控制方法以提高其传输可靠性。最后通过实际测试验证,该系统能有效的传输监测数据并对蓄电池进行定位,维护人员可通过云平台实时监测数据,降低远程监测的建设与维护成本。
