技术领域technical field
本发明涉及电力系统运行与控制技术领域，特别是一种基于EMS系统的继电保护在线监视与分析系统。The invention relates to the technical field of power system operation and control, in particular to an on-line monitoring and analysis system for relay protection based on an EMS system.
背景技术Background technique
现阶段绝大部分智能电网调度支持平台均已建设继电保护设备在线监视与分析应用。继电保护设备在线监视与分析应用是智能电网调度技术支持系统的实时监控与预警类应用下的一个子应用，对应于传统的保护故障信息管理系统，主要实现对保护装置、安全自动装置、故障录波器等二次设备的运行数据进行分析处理，便于调度运行以及继保等专业人员实时掌握二次设备的运行状态，辅助调度和保护人员判断故障性质和保护的动作行为，同时为综合智能告警等其他应用提供高可靠性的数据服务。At this stage, most of the smart grid dispatching support platforms have built online monitoring and analysis applications for relay protection equipment. The online monitoring and analysis application of relay protection equipment is a sub-application under the real-time monitoring and early warning application of the smart grid dispatching technical support system. The operation data of secondary equipment such as wave recorders is analyzed and processed, which is convenient for professionals such as dispatching operation and relay protection to grasp the operating status of secondary equipment in real time, assisting dispatching and protection personnel to judge the nature of faults and protection actions, and at the same time provide comprehensive intelligence Other applications such as alarms provide high-reliability data services.
参考说明书附图1，现有基于EMS系统的继电保护设备在线监视与分析应用系统架构主要分为三个区域，即I区、Ⅱ区和Ⅲ区，继电保护在线监视与分析应用的整体功能分为两个模块，数据应用处理模块和数据采集模块。数据应用处理模块主要负责保护数据与录波数据的模型管理、信息处理及告警、信息存储等，数据采集模块主要负责主子站之间的通信管理、规约管理机信息采集。上述两个模块均部署在安全Ⅱ区。Referring to Figure 1 of the instruction manual, the existing EMS system-based relay protection equipment online monitoring and analysis application system architecture is mainly divided into three areas, namely, I area, II area and III area, and the overall system of relay protection online monitoring and analysis application The function is divided into two modules, the data application processing module and the data acquisition module. The data application processing module is mainly responsible for the model management, information processing, alarm and information storage of the protection data and wave recording data, and the data acquisition module is mainly responsible for the communication management between the main and sub-stations, and the information collection of the protocol management machine. The above two modules are deployed in the security zone II.
结合说明书附图2，系统的基本功能包括设备建模、运行监视、故障分析、定值管理、信息归档、统计查询等。系统主要功能是对子站上送的二次设备运行信息、动作事件、录波简报、故障录波等数据进行分类处理，包括事件信息显示和告警、波形分析、数据存储等。同时从稳态监控系统获取开关变位和SOE信息，从模型管理获取网络拓扑分析结果，并向综合智能告警提供故障简报，向运行分析与评价系统提供设备运行信息。Combined with Figure 2 of the specification, the basic functions of the system include equipment modeling, operation monitoring, fault analysis, fixed value management, information archiving, statistical query, etc. The main function of the system is to classify and process secondary equipment operation information, action events, wave recording briefings, fault wave recording and other data sent by substations, including event information display and alarm, waveform analysis, data storage, etc. At the same time, switch displacement and SOE information are obtained from the steady-state monitoring system, network topology analysis results are obtained from the model management system, fault briefings are provided to the comprehensive intelligent alarm, and equipment operation information is provided to the operation analysis and evaluation system.
随着电网结构的日趋复杂，变电站端上送至调度端的信息体量不断扩大。目前的系统架构和实施方案已无法满足当前运行、检修的需求。主要存在的问题如下：As the power grid structure becomes more and more complex, the volume of information sent from the substation to the dispatcher continues to expand. The current system architecture and implementation plan can no longer meet the needs of current operation and maintenance. The main problems are as follows:
1、厂站端保护信息子站设备故障率高：1. The equipment failure rate of the plant protection information substation is high:
基于智能电网调度支持系统的继电保护在线监视与分析主站系统解决了调度端专业融合、信息共享的问题，并且提高了应用的使用性能，同时使主站的可靠性和维护性得到了加强。但是厂站端保信子站系统仍然是保信系统的短板，质量参差不齐的保信子站和职责交叉不清的二区数据网通道管理导致了保信子站出现故障率高、连通率低等问题；The relay protection online monitoring and analysis master station system based on the smart grid dispatch support system solves the problem of professional integration and information sharing at the dispatcher end, improves the performance of the application, and strengthens the reliability and maintainability of the master station . However, the Baoxin substation system at the factory station is still a shortcoming of the Baoxin system. The uneven quality of Baoxin substations and the unclear management of the data network channel in the second area lead to high failure rates and low connectivity rates of Baoxin substations. question;
2、自动化支撑力度不够：2. Insufficient automation support:
传统的自动化系统只能通过硬接点遥信的方式采集少量的保护信息，不能满足调度监控人员对二次设备监视、控制的需求，当电网发生故障时也不足以支撑开展故障分析；The traditional automation system can only collect a small amount of protection information through hard-contact remote signaling, which cannot meet the needs of dispatching and monitoring personnel for secondary equipment monitoring and control, and is not enough to support fault analysis when the power grid fails;
另一方面监控信息点维护工作量大，验收环节复杂，厂站端的遥信生成组态工作频繁。在智能变电站时代，保护装置不再提供硬接点信号，监控需要从保护软报文中抽取对应信号转换为普通遥信信号上送调度系统。随着变电站无人值守的推进，站端功能、业务和装置数量日渐增多，需要监控的信号不断扩容，信息点表的维护量也愈来愈大，运维工作量也随之加重。因此无论从提升调控运行技术支持能力方面还是减轻自动化工作量方面，都需要对自动化支撑保信系统工作进行变革；On the other hand, the maintenance workload of monitoring information points is heavy, the acceptance process is complicated, and the remote signal generation and configuration work at the plant station is frequent. In the era of smart substations, protection devices no longer provide hard contact signals, and monitoring needs to extract corresponding signals from protection soft messages and convert them into ordinary remote signaling signals and send them to the dispatching system. With the advancement of unattended substations, the number of station-side functions, services, and devices is increasing day by day, the signals that need to be monitored continue to expand, the maintenance of information point tables is also increasing, and the workload of operation and maintenance is also increasing. Therefore, it is necessary to change the work of the automation support and credit guarantee system in terms of improving the technical support ability of regulation and operation and reducing the workload of automation;
3、无法满足监控要求：3. Unable to meet monitoring requirements:
现阶段调度监控人员通过智能电网调度支持系统可以对保护信息进行调阅和应用，但是由于保护信息由厂站端保信子站上送，调度监控人员在使用中存在以下问题：1)、保护信息的传输不稳定，在电网异常或故障时往往由于子站连通上的故障导致保护信息和故障录波无法调阅；2)、保护信息没有进行分类和筛选，调度监控人员面临大量未加工的保护动作信息，无法及时作出判断和处理；3)、信息缺失现象频发，故障时刻由于厂站端上送的数据不全或不准确导致保信应用无法合成故障报告或报告中缺失故障相别、故障测距等信息，耽搁了检修的巡线处理。At present, dispatching and monitoring personnel can access and apply protection information through the smart grid dispatching support system. However, since the protection information is sent by the sub-station at the plant station, dispatching and monitoring personnel have the following problems in use: 1) Protection information The transmission is unstable, and when the power grid is abnormal or faulty, the protection information and fault recording cannot be retrieved due to the failure of the connection of the substation; 2), the protection information is not classified and screened, and the dispatching and monitoring personnel are faced with a large number of unprocessed protection The action information cannot be judged and processed in a timely manner; 3) The lack of information occurs frequently. At the time of the failure, due to incomplete or inaccurate data sent by the factory station, the Baoxin application cannot synthesize the fault report or the fault is missing in the report. distance and other information, delaying the line inspection processing of maintenance.
因此从继电保护在线监视与分析应用的功能提升和发展考虑，必须加强调度各专业的技术融合，积极吸取自动化专业在系统建设和维护上取得的经验，发扬监控专业在主站验收、建设方面的长处，发挥继电保护专业在保护信息综合处理、故障分析上的专业优势，充分利用职能电网调度一体化平台，建立起一套能服务于调度各专业且高效实用的继电保护在线监视系统。Therefore, considering the functional improvement and development of relay protection online monitoring and analysis applications, it is necessary to strengthen the technical integration of various disciplines in dispatching, actively absorb the experience gained in system construction and maintenance of automation majors, and carry forward monitoring majors in the acceptance and construction of master stations. Take advantage of the advantages of the relay protection profession in the comprehensive processing of protection information and fault analysis, make full use of the integrated platform of functional power grid dispatching, and establish a set of efficient and practical relay protection online monitoring system that can serve various dispatching specialties .
