【摘要】：随着经济和社会的发展,电力系统的机构越来越复杂,电力需求也在不断增加,整个社会对电力的依赖性越来越强。电力已成为国家的主要能源和经济命脉之一,电力系统的安全、经济、优质运行,也成为关系国民经济和社会发展的重要因素。近年来,世界范围内的多次大停电事故又显示出现代电网运行固有的脆弱性,停电事故对人们生活的影响不言而喻。如何有效地避免大面积停电事故,把可能会发生的停电事故消灭在萌芽状态,及时发现停电事故的苗头,发生停电事故后如何把影响减到最少,这些都依赖于电网监控系统以及调控员通过电网监控系统处理事故的能力,也就是需要一个可靠的电网监控系统加有事故处理能力的调控员。调控员处理事故的能力跟个人的工作经验有很大关系,个人工作经验积累的途径除了实际的事故处理,另外一个途径就是模拟事故演练。可见,这些问题的解决都需要从提高电网调度自动化系统可靠性上入手。根据国家电网公司“三集五大”体系总体构建思路和大运行体系建设的总体要求,要实现深化专业纵向集约,实施地县调一体化运作,扩展远方操作范围,提升设备监控运行管理水平,构建集中统一、权责明晰、工作协同、规范高效的电网大运行体系目标,必须建设一个能够适应地县一体化发展方向,充分体现信息化、自动化、互动化和智能化等特征的智能调度技术支撑系统,满足地调、县调对电网调度运行、设备集中监控等“大运行”业务需求。本文从调度自动化系统主站、传输通道以及调度自动化系统分站、后备电源、防雷等几个环节对调度自动化系统可靠性影响进行了深入分析研究,提出了提高可靠性的设计方案。这项工作不仅具有战略的必要性,而且具有时代的紧迫性。
[Abstract]:With the development of economy and society, the mechanism of power system more and more complex, the power demand is also increasing, the whole society of power become increasingly dependent. Electric power has become one of the main energy and the country's economic lifeline, power system security, economic operation, high quality, has become an important factor in national economy and society the development of the relationship. In recent years, in the world many blackouts showed the vulnerability of the generation and power grid operation inherent power outages, the impact on people's lives is self-evident. How to effectively avoid blackouts accidents may occur, the blackout accident nipped in the bud, discover the blackout signs. The power failure accident of how to reduce the impact to a minimum, these are dependent on the grid monitoring system and control through the ability to deal with the accident monitoring system of power grid, there is a need to Grid monitoring system with reliable control member accident handling ability. Have a great relationship with the ability of regulation to deal with the accident of personal experience, way of personal work experience accumulated in addition to handling the actual accident, another way is to simulate the accident drills. Therefore, to solve these problems need to start from improving the reliability of power grid dispatching automation system. According to the national Power Grid Corp "three overall set five" system overall construction ideas and operation system construction requirements, to deepen the professional intensive implementation of the county longitudinal integration, extended operation, remote operation range, improve operation and management level of construction equipment monitoring, centralized and unified, clear responsibilities, work, power high standard and efficient operation system goal, we must build a county to adapt to the trend of integration, fully reflect the information technology, automation, interactive The supporting system of intelligent scheduling technology and intelligent characteristics, to meet the county, operation of the power grid dispatching, monitoring and other big operation business needs. The dispatching automation master station system, transmission channel and dispatching automation system of substation, backup power supply, lightning protection and other aspects of the impact of the dispatching automation system reliability the analysis and research, put forward to improve the design reliability. This work not only has the necessity and urgency of the strategy, with the times.
