【摘要】：电能的生产使用过程,以电力调度为纽带,发、输、变、配电各部门密切配合,统一协作,以最大限度的满足用户的用电需求为目的。整个过程应杜绝人为因素电网故障的出现,减少对电网、设备以及人身的危害。作为电网调度指挥机构--电力调度控制中心,对电网数据的即时性、准确性、安全性有了更高的要求。基于电力系统调度的运行实践开展新的探索受到了广泛的重视。各级电力调度控制中心,除负责所辖范围调度指标编制、持证上岗、业务培训、发布风险预警、编制应急预案等专业管理外,还负责参与设计电网投产规划、编制电网运行方式、制定电网、电厂设备停电计划、电网调度运行数据报送、指挥电网扩建、运行、故障处置等工作。省级电力调度控制中心,贯穿联系国调、分中心与本省内各地市调度控制中心,对本省内调度专业进行技术指导和专业管理。电网调度运行数据报送,即生成调度报表,要求报表的制作尽可能的迅速准确,以提高报送质量,便于对电网运行进行总体分析;指挥电网运行,可以概括为电网状态实时集中监测和调度操作两部分。合理的调度控制要求每个部分的工作都尽可能迅速、准确、安全。数据的采集和传输是电网状态实时监测方面的重点,要求无效数据和错误数据的数量不能过多,过多的无效数据和错误数据会导致数据处理的耗时大大增加,也不利于电网安全、经济运行;如果调度操作不得当,可能造成电网框架薄弱,甚至造成设备误停电等,给人民正常生活造成不便,给工厂企业造成经济损失。这就需要有一套智慧安全的操作票系统来辅助验证调度指令是否适当、控制操作是否正确无误,保证调度操作顺利进行,不发生恶性误操作事故。本文分析了当前电力调度系统报表报送、监控信息传送、调度操作票系统现状及存在的问题。从缩短生产报表制作时间,降低无效信息数据数量,提高调度操作票智能化三个方面展开论证,提出执行方案,并最终取得以下成果。在报表制作时间方面,研究报表报送用时过长问题,确定原因为人工核对错误数据用时较多和源数据无法快速定位。通过开发报表的"自动校核"以及"源数据超链接定位"功能,顺利解决了这两大问题;在无效信息数据处理方面,从减少500kV变电站无效告警信息数量的目标出发,分析了造成无效信息数量巨大的五大因素。对此提出了监控信息梳理、监控系统优化开发、设定伴生信息屏蔽阀值、设定越限信息屏蔽阀值、建立信息过滤机制等措施。实践证明,措施有效,达到了预期效果;在操作票智能化方面,研制开发的智慧操作票系统,具有智慧防误操作校核、操作票流转、与OMS系统交互关联、自动回填检修记录、调度长授权监护操作等功能。开票方式可由调度员灵活选择。特别是防误校核功能,非常适用于当前调度工作。符合山东省调生产实际的新型智慧调度操作票系统开发成功。本文对于省调实践的探索具有实际价值和重要意义。
[Abstract]:The process of electric energy production and use, with the power dispatching as the link, transmission, transmission, change, and distribution of various departments to cooperate closely, to meet the user's demand for electricity to the maximum limit. The whole process should eliminate the emergence of human factors power grid failure, reduce the damage to the power grid, the preparation and the human body. The dispatching control center has a higher requirement for the real-time, accuracy and security of the power grid data. A new exploration based on the operation practice of power system scheduling has been widely paid attention. In addition, the provincial power dispatching control center is responsible for the planning of the power grid, the operation mode of the power grid, the planning of the power grid, the power outage plan of the power plant equipment, the dispatching and operation of the power grid, the expansion of the power grid, the operation and the fault disposal. The center, the technical guidance and professional management of the dispatching specialty in this province. The dispatching and running of the power grid, that is, the dispatch and operation of the data, that is, to generate the dispatch report, and to require the production of the report to be as rapid and accurate as possible so as to improve the quality of the dispatch and facilitate the overall analysis of the operation of the power grid, and the command of the power grid transportation can be summarized as the real-time centralized monitoring and scheduling of the state of the power grid. Operation two parts. Reasonable scheduling control requires that the work of each part is as fast, accurate and safe as possible. The collection and transmission of data is the key point of real-time monitoring of the state of the power grid, which requires that the number of invalid data and error data can not be too much, too much invalid data and error data will lead to the time consuming of data processing greatly increased. It is also not conducive to the security of the power grid and economic operation. If the scheduling operation is not appropriate, it may cause the weak frame of the power grid and even cause the equipment failure to cause the inconvenience to the people's normal life and cause the economic loss to the factory enterprises. This requires a set of intelligent and safe operating ticket system to assist the verification of the appropriate operation instruction and control operation. Whether it is correct and unmistakable to ensure the smooth operation of the dispatching operation and no malpractice misoperation accidents, this paper analyzes the current situation and existing problems of the report reporting, monitoring information transmission, dispatching operation ticket system of electric power dispatching system, reducing the production time of production reports, reducing the number of invalid information data, and improving the intelligentization of dispatching operation tickets three The reason is that the reason is that the reason is that the reason is that the reason is that the manual check the error data and the source data can not be fixed quickly. The function of "automatic checking" and "the source data hyperlink positioning" function can be successfully solved. In the aspect of invalid information data processing, from the target of reducing the number of invalid alarm information in 500kV substation, this paper analyzes the five major factors causing the huge number of invalid information. This paper puts forward the monitoring information combing, the optimization and development of the monitoring system, the setting of the associated threshold of information shielding, setting the threshold of shielding information and setting up the threshold. Information filtering mechanism and other measures. Practice has proved that the measures are effective and achieve the expected effect. In the intelligent operation ticket, the intelligent operation ticket system developed and developed has the functions of intelligent anti misoperation checking, operation ticket circulation, interrelated connection with the OMS system, automatic backfilling maintenance records, dispatcher's authorized monitoring operation and so on. The mode of ticket opening can be dispatcher The flexible selection, especially the anti error checking function, is very suitable for the current dispatching work. The new intelligent dispatching operation ticket system which conforms to the actual production of Shandong province has been developed successfully. This paper is of practical value and significance for the exploration of the practice of provincial adjustment.
