【摘要】：随着连江配电网规模的不断扩大,电网结构和运行方式的不断改变,配网调度操作任务的日益增多,对调控人员的工作能力要求越来越高,因工作疏忽而导致的“误操作、误调度”成为电网事故的主要原因之一。调度员单凭脑子记忆和判断难以杜绝误调度事故的发生,如何提高工作效率和安全调度水平成为当前配网调度面临的重要课题。本文首先根据当前县级电网调度工作的新形势,对课题进行需求分析,提出了建立配网调度操作防误管理系统的总体思路,总结以往的研究成果,确立了系统的各项功能和性能,对系统的软硬件结构和各个功能模块进行详细设计,实现了与SCADA系统共享实时数据,与配电生产管理信息系统集成的目标,集配网正常运行方式、图形开票、模拟操作防误、仿真培训、操作票流程化审核与管理等多种实用功能于一体,设计并实现了用户可维护的县级电网调度操作防误管理系统,实现配网调度生产流程管理的自动化和智能化,提高配网调度操作的智能性和安全性。系统综合应用配电网络拓扑分析、操作仿真等技术,建立实际配电系统的网络模型；采用图形开票技术,对调度指令票进行智能拟写、自动模拟、拓扑着色、自动安全校核、全流程管理等。该系统是在实际配网图模型基础上对调度指令进行智能拟写和防误校验的软件系统。系统通过在一次接线图上点击操作设备生成调度操作指令,同时,以调度规程和倒闸操作规定作为防误校验依据,并结合电网当前运行方式来判断各步操作指令的合理性,对误操作进行警告或提示,提高了调度操作指令票的生成效率和准确性,弥补目前配网调度技术支持系统方面存在的不足。本系统达到了国家电网公司标准中调度智能操作票系统的应用功能规范,研究成果还作为连江公司的科技项目投入开发应用,在现场实施过程中,不断修改和完善系统功能,以满足配网调度运行工作的需要。实践证明,该系统是配网调度工作有力的辅助工具之一,对于减轻调度员工作强度、防止误调度事故、提升电网安全管理水平起到了重要的作用。
[Abstract]:With the continuous expansion of the scale of the distribution network in Lianjiang, the continuous change in the structure and operation mode of the power grid, the increasing number of operation tasks of the distribution network, the increasing demand for the working ability of the control personnel. The "misoperation and misscheduling" caused by negligence of work has become one of the main causes of the power grid accident. It is difficult to prevent the occurrence of misscheduling accidents. How to improve the efficiency and the level of safety scheduling has become an important task for the current distribution network scheduling. Firstly, this paper, based on the new situation of the current county power grid dispatching work, analyzes the needs of the project, and puts forward the general idea of establishing the control system of the distribution network adjustment operation. The research results have established the functions and performance of the system, designed the software and hardware structure of the system and each function module in detail, realized the goal of sharing real-time data with the SCADA system and integrated with the distribution management information system, set the normal operation mode of the distribution network, the graphics ticket opening, the simulation operation prevention and control, the simulation training and the operation ticket. There are many practical functions such as process audit and management. The system is designed and realized by the user to maintain an anti error management system for the dispatching operation of the county power grid. It realizes the automation and intelligence of the production process management of the distribution network, and improves the intelligence and security of the dispatching operation of the distribution network. The network model of the actual distribution system is set up by the technology of other technologies, and the graphics open ticket technology is used to carry out intelligent writing, automatic simulation, topology coloring, automatic security checking and all process management. The system is a software system for intelligent writing and anti error checking of scheduling instructions on the basis of actual distribution network model. The system is passed through the system. At the same time, the operation instruction is generated by clicking on the operation equipment in a wiring diagram. At the same time, the scheduling regulation and the regulation of the switching operation are used as the basis of the error proof check. The reasonableness of the operation instructions of each step is judged by the current operation mode of the power grid. The warning or prompting of the misoperation is carried out to improve the efficiency and accuracy of the operation instruction ticket. The system meets the shortcomings of the current distribution network scheduling technology support system. This system has reached the application function specification of the dispatching intelligent operation ticket system in the national Power Grid Corp standard. The research results are also put into development and application as the science and technology project of Lianjiang company. In the field implementation process, the system function is constantly modified and perfected to meet the distribution network. The practice has proved that the system is one of the powerful auxiliary tools of distribution network dispatching work, which plays an important role in reducing the intensity of dispatchers, preventing misdispatching accidents and improving the safety management level of the power grid.
