毕业设计(论文)基于plc的远程监控系统的设计与研究.doc

摘 要 智能电网时代的SCADA技术是以设备对象和网络模型为核心的理念来进行设计的，它具有处理面广、人工智能化水平很高的明显优点，并且具有方便的拓展性，在这基础上能够方便的扩展出非常多的功能化模块，比如电厂脱硫的监视、新能源的综合监测等，而不必要增加一些另外的应用或系统。这种技术能够为智能电网的调度技术支持系统及智能电网调度自动化生产运行提供坚强的技术支撑，有利于促进我国智能电网的全面发展。 由调度中心收集的网络信息必须要通过相应的应用软件的处理，以便最终实现调度生产过程中的各种各样的方式。在已经掌握一些现有的应用软件的条件下，调度员可以很快的监测到电网在运行过程中的各种状态，可以很快并且很方便地分析电网实时运行的稳定性和经济发展的趋势，在事故情况下尽快的完成相应的判断、决策，才能够对遥远的厂，站实施有效的远程控制和远程调整。 本课题针对电网调度自动化系统的管理和监控，详细分析和说明了SCADA系统中的软硬件设计，并对SCADA系统及其发展和SCADA系统应用于电网调度自动化系统中的若干相关技术进行了初步的研究。针对电网调度自动化系统工作原理，详细的分析和描述了SCADA系统的硬件和软件的设计，初步研究了SCADA系统和SCADA系统的设计在电网调度自动化系统中的一些相关技术。 SCADA系统其实是一个实时数据监控与数据采集分析的系统。通过对SCADA仿真系统的研究，让我们对SCADA仿真系统有一个比较具体的了解，熟悉SCADA仿真系统的发展历程，当前的发展状况以及未来的发展趋势。充分体会到了SCADA仿真系统在国家电网调度中发挥的不可或缺的作用。 关键词: SCADA; 电网调度; 仿真；智能电网；自动化 ABSTRACT The smart grid era of SCADA technology is based on the device object and the network model as the core concept to design, it has a wide treatment surface,the obvious advantage of the high level of artificial intelligence, and has a convenient expansion in this basis canfacilitate the expansion of a very large number of functional modules, such as desulfurization plant monitoring, energy monitoring, and unnecessary increase in some other application or system.This technology can support the automation of production and operation of thesystem and the smart grid scheduling for smart grid scheduling technology to provide strong technical support and help to promote the comprehensive development of Chinas smart grid. Network information collected by the dispatch center must pass the appropriate processing of the application software, so that the final scheduling of the production process in various ways. Conditions have mastered some of the existing application software, the dispatcher can quickly monitor the various states of the power grid during operation, you can quickly and easily analyze the grid run-time stability and economic development trends the completion of the judgment, decision systems, a detailed analysis and description of the SCADA
