发电厂运营是电力生产的过程,也是资源消耗的过程。对于像发电厂这样的资产密集型企业,只其资产维护费用可占到生产成本的40%余,因此,如何合理、高效地利用和维护电厂资源将是优化企业生产力,降低单位生产成本,提高企业竞争能力的关键因素之一。这里所谓资源,指一切有价值的事物,发电企业的资源配置复杂多样,数量庞大,其中尤以各种设备或设施资产及相关技术资料为重。发电厂技术密集、资产密集,涉及多个专业,又包含很多有机的系统,不仅其设备本身构成复杂,而且其相互关系错综复杂:包括原理性功能关系、拓扑连接关系、空间位置关系等。电厂资源信息是电厂所有自动化系统都需要的信息,但目前各发电企业广泛存在的“信息孤岛”大都各自维护自己所需的资源信息,没有标准、统一的资源信息模型,这种现象已经对发电企业信息自动化系统的健康发展造成了很大障碍。本课题研究旨在从根本上解决发电厂信息自动化系统的整合问题。为此,本文提出了可视化电厂信息平台的概念及设计方案,并在此基础上,统一规划设计电厂各种业务应用系统。论文采用面向对象的系统思想和方法,全面分析发电厂资源信息构成,建立完备的资源信息模型,并形成能够服务于所有应用功能的基础信息平台。完备的资源信息模型将资源对象的静态信息、空间信息、图形信息等揉合在一起,形成完备的、面向对象的、可视化信息模型,从而构成所谓“可视化电厂资源基础信息平台”。可在此之上形成各种发电厂信息自动化应用,为电厂信息自动化系统的统一规划设计奠定了平台化的基础。基于本文设计的可视化电厂资源信息平台,结合邹县发电厂实际情况,开发形成了可视化电厂资源管理系统,实现了电厂资源的高效综合可视化管理。现场应用效果良好。
Power plant operation is not only a process of power generation, but also a process of resource exhausting. As for assets-condensed enterprise just like power plant, only the cost of the assets management can account for more than 40% of the whole production cost. So how to use and maintain the power plant"s resource correctly and efficiently would be the key factor to optimize the productivity, to decrease the generation cost and to enhance the competition.The so-called resource, it"s about all the valuable items. The resource deploy of a power enterprise is complex and diverse, be great in number. Especially various facilities and establishments and it"s involved engineering documents. It"s technology-condensed and assets-condensed in power plant, it involves several academic fields and includes many organic systems. Not only the formation of the equipment is very complex, but also the relations between the different ones. It is includes relationship of principle function, relationship of topology, relationship of position and so on.The power plant resource information is needed in all the automatic systems in power plant, but right now, the "information island" existing comprehensively in every power enterprise which maintains the resource information needed only in itself. There is no standard and uniform resource information model. This phenomenon has brought big obstacles to the healthy development of the information automatic system for the power plant.The purpose of this paper is to resolve the conformity problem of the information system for the power plant from the root. We proposed the concept and the design project of the visualized power informationplatform. So we can layout and design various operation application systems of power plants.This paper adopts the object-oriented concept and method. We have comprehensively analyzed the formation of the power plant resource information, established the self-contained resource information model, and formed the basic information platform that can serve all the application function. The comprehensive resource information model put the static information of the resource objects, space objects, graphics objects together. Come into being the comprehensive, object-oriented, visualized information model. So the so-called visualized basic information platform for power plant is formed. We can make various power plant information automatic application on this base. To make a platform for the uniform plan and design for the power plant information automation system.According to the actual situation in ZOUXIAN power plant, we developed the visualized power plant resource management system based on the visualized power plant resource information platform studied in this paper. With that, the power plant resource can be managed efficiently and visualized comprehensively. And it obtained pleasant result in actual application.
