【摘要】：国家电力建设飞速发展,为了提高管理水平,智能化建设迫在眉睫。变电站作为电网中的核心单元,数量巨大,是智能化建设的中坚部分。在实际运行中,变电站内均安装了环境监测、视频监控及报警系统等辅助系统,但绝大多数设备都是分批次安装和分步骤操作的,致使系统内部各个层次之间仍然相互独立,以至于几乎全套操作系统都需要组织相关工作人员进行管理,因此要实现多个操作系统的统一监督和控制、并进行实时管理,将会使监控和管理成本大幅度上升。虽然目前已有多座变电站实现联网或者远程管理,但存在缺乏相关标准规范、过程层设备稳定性、可靠性有待验证、缺乏相关评估体系和手段等问题,影响着变电站生产运行的效率,不利于电网安全运行水平的进一步提高。因此,为了实现智能变电站的建设,智能变电站辅助系统综合监控平台,不可或缺。同时,在满足国家电网规范的基础上,智能变电站辅助系统综合监控平台,更应该具备其高度灵活性,以满足不同区域和不同建设水平情况下,变电站智能化建设的需求。总体需求方面,智能变电站辅助系统综合监控平台,应该依托现有网络信息,完成消防安防、环境测控、视频监视及各种智能设施的互联互通,同时具备结合用户业务管理的一系列功能,并完成对各变电站(所)的设备运行数据、图像、周界安全防范、环境参量等进行监控,能够实时、准确地掌握各个变电站(所)设备的运行现状,并及时解决现场发生的故障,适应电力系统的高速发展和智能化建设。本文首先针对目前变电站存在的不足,提出了智能变电站辅助系统综合监控平台的系统需求,为后续功能模块的设计奠定基础。其次,对智能变电站辅助系统进行了方案研究,针对系统的体系结构,对各个主要的功能模块：安全防范子系统、环境监控子系统、视音频监控子系统进行详细介绍；并做出智能变电站辅助系统综合监控平台的总体方案设计,从系统数据的单向流向和系统功能的分层部署两个角度对总体方案的实施,提出可行的辅助系统联动和整合方案。最后把系统应用到晋中地区,并作出效果和效益分析,可看出工作效率、可靠性及成本都得到很大的提高。并对辅助系统未来的发展趋势进行了展望。
[Abstract]:With the rapid development of national electric power construction, intelligent construction is imminent in order to improve the management level. As the core unit of power network, substation is the backbone of intelligent construction. In actual operation, auxiliary systems such as environmental monitoring, video monitoring and alarm systems are installed in substations, but most of the equipments are installed in batches and operated step by step, which makes the various levels of the system still independent of each other. So that almost all operating systems need to organize related staff to manage, so to achieve unified supervision and control of multiple operating systems and real-time management, monitoring and management costs will be greatly increased. Although many substations have been connected or managed remotely, there are still some problems, such as lack of relevant standards, stability of process layer equipment, reliability to be verified, lack of relevant evaluation system and means, etc. It affects the efficiency of substation production and operation, and is not conducive to the further improvement of power grid safe operation level. Therefore, in order to realize the construction of intelligent substation, intelligent substation auxiliary system integrated monitoring platform, indispensable. At the same time, on the basis of meeting the national power network specification, the intelligent substation auxiliary system integrated monitoring platform should have its high flexibility, in order to meet the different areas and different construction level, substation intelligent construction needs. In terms of overall demand, the intelligent substation auxiliary system integrated monitoring platform should rely on the existing network information to complete the interconnection of fire protection, environmental monitoring, video surveillance and various intelligent facilities. At the same time, it has a series of functions combined with user service management, and can monitor and control the equipment operation data, images, perimeter security, environmental parameters and so on of each substation in real time. Accurately grasp the operation status of each substation equipment, and timely solve the field fault, adapt to the rapid development of power system and intelligent construction. Aiming at the deficiency of substation at present, this paper puts forward the system requirement of intelligent substation auxiliary system integrated monitoring platform, which lays a foundation for the design of follow-up function module. Secondly, the scheme of intelligent substation auxiliary system is studied. According to the system structure, the main function modules are introduced in detail: security subsystem, environment monitoring subsystem, video and audio monitoring subsystem; The overall scheme design of the intelligent substation auxiliary system integrated monitoring platform is made, and the feasible auxiliary system linkage and integration scheme is put forward from the view of the one-way flow direction of the system data and the hierarchical deployment of the system function. Finally, the system is applied to Jinzhong area, and the effect and benefit are analyzed. It can be seen that the work efficiency, reliability and cost have been greatly improved. The development trend of the auxiliary system in the future is prospected.
