数字变电站的目标主要是通过三维设计管理系统来进行实现,3D设计系统和数据库管理系统的应用都基于数据库反映了3D、2D或1D形式变电站的现实与逻辑关系,并且同时所有图表映射的数据库数据、图表都是一致的。为了实现变电站高效管理的建设和运行,变电站各阶段的所有信息将从设计、采购、制造、施工、调试、运行、维护等方面统一规划。要在设计阶段建立如此庞大的数据库,必须依靠全面有效的三维设计体系和高度集成的数据库管理系统。三维综合设计系统具有构建变电站生命周期信息平台的能力,可为业主提供数字变电站,基本工作如下:1)在项目开始时建立时统一识别系统,从设计通过数据仓库平台开始,工程公司和工程公司的信息有效交付给适当的采购部门以及施工部门,最终将进行变电站的运行维护。2)基于以3D设计系统的变电站设计为核心设计手段,通过数字变电站技术协同设计网络,确保在正确的时间,正确的地点,获取正确的信息后进行相应的设计。3)使用集成协同工程设计、有效控制版本和相应的工作流程,集中控制和管理所有技术文件、版图纸和升级,使设计知识和成果完整地保存在统一的中央数据库中。4)通过整合所有甲方和承包商的变电站项目管理和运行管理系统,组建最终的数字变电站,对现场和现场施工安装,同时对调试和集中管理质量控制信息进行安排。5)随着项目进展,我们将继续积累数据,维护数据的一致性,建立标准化模型、数据、图纸以及文件。在项目建成后,业主可以最终提交变电站未来运行所需的运行维护数据,方便数字变电站维修管理。2.2.三维数字变电站实用基础三维数字变电站的具体应用可分为三个阶段。在设计阶段,为了实现三维模型与强大的信息文档结合,形成了工厂信息系统的完整三维可视化。它需要如此多的信息,如大量设计相关的一维和二维设计信息、材料、成品的综合三维模型,以及建设和运行和维护必要的信息。在基础设施建设阶段,甲方和施工单位采用三维模型查询设计信息,直接提取库存各种设计图纸、设备材料与模型,并向采购系统提供详细的采购信息,模拟施工进度和基础设施以及检修,同时提升预留空间,直观的三维模型指导施工,通过INTERNET网络向远程施工现场提供视觉设计通信服务在生产运行中,甲方通过企业数据仓库提供标准的项目模板。变电站工程信息统一设置在设计和管理界面,可以查阅所有图纸之间的智能关系、设计内容、图纸,同时可以自动生成工程材料汇总表、卷目录。在整个过程中,查询各个阶段的信息为核心的阶段,同时还包括建立3D模型和数据库、辅助运行操作、维护和运行辅助数据维护、对应的文件管理,培训人员等。项目工作流程如图1.三维模型能够实现统计计算,生成数字模型施工图。软件不仅可以通过三维和多角度显示变电站的实际情况,使得所有设备,电线和结构的特殊关系如平面打印,也可以实现真正的防雷检查、精确的材料统计、 三维模型。另外,为了更好地了解设计意图和设计优势,可以在变电站中使用三维动画报告设计,用三维视觉充分体现项目设计。变电站平台和数字传输应用程序的三维设计查询和检索信息,为甲方和项目管理单位提供极大的便利,无需大量工程图纸,只需通过网络浏览器即可。三维变电站将能够看到现实的虚拟尺寸模型,以及所有的工程图纸和文件、所有的工程数据。操作十分简单,只需点击模型即可。同时它可以自动访问文件数据。即使不用在长期的研究所、施工现场,只需登录网络即可查看实时设计进度、施工进度、采购状态、调试参数、设备状态的实际运行情况,以及还能直接在模型中注释评论。3.研究内容和实施计划图形技术在三维现实中占有很大的比重。如何将真实的视觉体验带到数字空间的关键是是否能够模拟真实世界中的所有表面,这是一种包括照明计算、图形等通过设置纹理层的输入和操作的过程,在过程中可以使用的输出作为下一层的输入,也可以作为最终的结果。对于3D硬件的两个API,OpenGL和Direct3D有它们的固定渲染管道,也就是管道。诸如位置,法线,纹理坐标等顶点的数据将被提供给管道,然后定义光源4,5,你可以得到一个渲染的图像。在这个特定的呈现过程中,程序设计人员没有办法控制。从DirectX 8和OpenGL扩展开始,在渲染流水线中引入了可编程特性,图形硬件开始支持可编程特性,这样开发者就可以编写一个小程序,并在图形卡上运行它来控制渲染的过程。图形硬件的功能是由流水线的功能单元开发成两个可编程单元:顶点单元和像素单元。对顶点单位和像素单位通过编程,你不仅可以优化算法,但也不能完成最初实现功能,如分发负载顶点之间的管道和像素管道承载能力;通过自定义算法,提高固定功能的算法,甚至完全创建原始算法。在微软DirectX中,这段程序代码被称为Shadier。实际上,Shadier(渲染或着色)是程序拥有操作3D对象的能力,并且可以由GPU来执行。通过这些程序,程序员可以得到他们最想要的3D图形效果。一个3D场景通常包含多个Shadier。其中一些Shadier负责处理3D对象的表面,有些负责处理临时缓存的屏幕对象。有两种类型的Shadier,一种是峰值水平,被称为顶点Shadier,取代了照明部分的固定渲染管道,程序员可以控制顶点转换、照明等。处理顶点着色浆果的硬件单元称为顶点Shadier处理器(顶点处理单元)。另一个是像素级的像素着色器,它可以替代固定渲染管道中的光栅部分。程序员可以控制像素颜色和纹理采样。在硬件单元中处理像素Shadier称为像素Shadier处理器(s-像素处理单元)。同时,引入了文件格式来独立地保存代码:文件格式。因为它独立于程序的修复,因此用户可以更改不同的Fx文件,并且可以轻松地改善程序的视觉效果,而无需重新编译程序。在渲染过程中引入可编程特性是一种实时渲染的革命,这给了开发人员更多的创造性自由,因此用户可以创造更好的效果。在这个项目中,我们使用Shadier来定义模型的材料,一方面,改进了的光照算法,并使纹理融合得到了优化,另一方面,这有利于在将来很容易地修改材料的结果。该程序使用模块化结构。模块是相互独立的。标准化的参数用于传递数据。一方面,这有助于维护一个清晰的结构,同时也有助于修改和维护。模块设计过程设计可分为数据模块设计、菜单模块设计和交互式动画模块设计。数据模块设计主要考虑纹理处理、模型制作、与目标硬件的配置,设置纹理的格式和分辨率,控制多边形的总数,多边形的预算分配,总的模型数据格式和结构。设计菜单模块的目的是减少使用的难度,并将重点放在用户体验上。在交互式动画模块设计中,不需要算法的效率,但是您应该尝试维护一个清晰的逻辑结构来简化维护。(1)典型的工程图书馆管理软件使用大型网络数据库来规范典型的通用设计工程的设计、设备制造商常用的数据、备用库、设备和其他典型的集中管理,以方便搜索和下载,并通过许可设置确保数据库的安全性。与此同时,平台数据库对网络成员开放。成员可以同时扩展开放设备数据库。设备库中的许多图形设备参数都存储在设备库中。通过网络管理和许可机制,实现数字设计数据和流程管理。(2)设备的三维参数化建模平台独特的参数化三维设备模型,只要输入的关键参数,您将生成一个平面,横截面,设备的侧面和固体,得到“实时修改三维设备”(参数变化,设备实时更新)。软件提供了一种快速而简单的方法来创建三维的设备,这样它就可以很容易地绘制出三维图形。(3)总布局和部分设计师选择线出口方向和坑门位置,并选择适合国家电网通用设计的程序员,平台将自动生成初步的电子总平面,设计者进行调整,平台将自动生成最终的电气总平面。该平面包含大的三维数据库信息,如设备参数和大小、建筑尺寸、线材类型和各种设备的数量。它可以自动生成一个材质表。对于一般的布局,设计师如果想要分配截面视图,可以切割它,这可以由配电单元的截面材料来生成。(4)关于变电站照明防雷计算的3-d图是平面图形绘制的一个过程。平设计师只需要在不同的地方放置避雷针即可。只要设计师类型对避雷针的位置和高度,平台将自动生成三个sionalanti-thunder图,如果有建筑或设备暴露在范围外,平台会发现避雷针不能满足需要,就会生成一个计算说明书。(5)功能强大的计算功能设计平台可以做计算功能:1)短路电流计算和设备选择,2)电变电表的动态接地;3)线张力计算;4)电计算;5)次电路继电保护设置计算;6)电缆和统计;7)悬管计算软件。4.总结 该方法通过三维集成技术来组合各种数据,构建虚拟步调系统进行变电站设计,提供设计,规划,决策和视觉参考,为进一步修改的程序员提供了有用的工具。在这种方法中,用于数据集成、复杂专业数据的三维现实技术通过虚拟现实技术进行视觉反映,更有利于交流、识别问题、提高改进、提高处理效率、优化施工。这种方法可称之为是最有效的变电站设计工程助理。通过互联网发布设计,让更多的人能够了解它,甚至可以参与决策,让人们可以从变电站的普遍知识中受益,增强人们对变电站的了解。这也可以增加应用环境的理论水平,使人们能够更快地了解它。原文:TheUseofThree-DimensionalIntegratedDesignSysteminSmartSubstationDesignAbstract:Thetraditionalpowerdesign,construction,hasbeenabletomeettherequirements,butithasnotbeenestablishedengineeringdatadatabasesupportandthecorrelationbetweenthedataispoor,duetoinadequatecoordinationamongdesignprofessionals,designeasilyleadtomistakes,fieldproblems,anddesignresultsfailedinallaspectsoftheprojecttobefullyutilized.Withthetechnologyofthree-dimensionalintegrateddesignsystempenetratesinallwalksoflife,theintroductionofthree-dimensionalintegrateddesignsystemsubstationdesignsolutionsandtheapplicationofcommondevicesofStateGridCorporationinrecentyears,whichprovidetechnicalconditionsfortheapplicationofvirtualrealitytechnologyinsubstationdesign.Accordingtoitsowncharacteristicsofsubstationproject,wenowproposeprospectonvirtualrealitytechnologyinsubstationdesignapplication.Keywords:Database;SubstationDesign;VirtualRealityTechnology;3DIntegration1.IntroductionWiththerapiddevelopmentofinformationtechnology,three-dimensionaldesignhasbecomeaninevitabletrendanduniversaldemandinthedevelopmentofpowerengineeringdesigninthefuture.Asthecoreofdigitalintelligentsubstation,three-dimensionalmodelmustapplyintelligent3Ddesignthroughfull-featuredthree-dimensionalintegratedsystemthatproducesintelligentsubstationapplication,basingonthemodelcaseofmainwiringanddistributionsystemsofuniversaldesignintheStateGridCorporation,anddependingonappropriatechoiceofgenericengineeringdesign,appropriateadjustmentsinthemainwiringaccordingtotheprojectsize,andthenchoosethedirectionofthelineandstopthedooroutletlocationtoadjustthedevicetypeandrelateengineeringdesignparametersaccordingtotheStateGridCorporationcommondeviceinterfaceallowingdesigners,automaticgeneratedintervalcrosssectionalviewoftheelectricaldistributionequipmentandgenerallayoutofthefloorplan.Anditcanbeabletocheckthesecurityofthedevice
