【摘要】：电网调度二次系统以计算机和通信技术为基础,为电网一次系统的运行和管理提供保障和技术支持,实施有效的监视和控制,对提高电网运行的稳定性和安全性起着重要的作用。随着电网的发展,调度二次系统的服务支持和技术保障作用日益突出,运维工作也随着调度二次系统的数量与种类增多,使得传统监视手段的局限性更大突出。在实际工作中,不同二次系统的信息不能集中监视和查询,运行工况信息和系统报警信息分散在不同的监视终端上,不便于及时发现系统异常;另外对二次系统的运行工况信息和服务工况信息的监测,仍依赖其本身的报警功能,当系统故障时外部无法及时发现。电网二次系统是电网安全、稳定、优质、经济运行的重要保证和技术手段。但各系统根据业务特点都独立运行,运维人员分散于不同的职能部门,也造成了市县调度二次系统运维不集中,运维程度差异较大。此外,由于分布式能源的接入以及用电侧交互需求的持续增长,导致电网运行复杂度不断增加,从而使得调度操作人员面临越来越大的决策压力。因此将二次系统的安全风险问题纳入当前运行风险决策当中,对其进行综合的定量评估,显得极为重要。本论文根据电力行业安全生产监控的技术需要,提出了对原有二次系统进行实时监控的自动化系统,可在电网、变电站及各生产单位实现实时数据采集、预警分析、图表显示、曲线图和柱图生成、中文报表生成、事故综合处理等功能。系统平台采用基于Flex/Extjs+Struts2+spring+Ibatis的开发框架,运用java语言进行开发。经过详细的需求分析、设计与实现,目标系统的研究内容包括系统管理、业务管理、机房管理、统计分析、异常告警、实时监测和采集管理。目标系统的应用,对二次设备和系统运行参数的信息进行监视采集,并根据预先定义的告警规则对异常采集数据进行实时告警通知,便于及时发现和处理异常情况,为电网安全、稳定运行提供保障数据。使整个电网的生产现场达到无人值守、调度班组少人值班的高自动化水平。提高了自动化水平和运行的安全可靠性。
[Abstract]:Based on computer and communication technology, the secondary power dispatching system provides guarantee and technical support for the operation and management of power grid primary system, and implements effective monitoring and control. It plays an important role in improving the stability and safety of power grid operation. With the development of the power grid, the service support and technical support of the dispatching secondary system are becoming more and more prominent, and the operation and maintenance work is increasing with the number and variety of the dispatching secondary system, which makes the limitation of the traditional monitoring method more prominent. In practice, the information of different secondary systems can not be centralized monitored and queried, and the information of operating conditions and system alarm are scattered on different monitoring terminals, so it is not convenient to find system anomalies in time. In addition, the monitoring of the operation condition information and the service condition information of the secondary system still depends on its own alarm function, and it can not be found out in time when the system fails. Power grid secondary system is an important guarantee and technical means of power grid security, stability, quality and economic operation. However, each system runs independently according to the characteristics of the business, and the operation and maintenance personnel are scattered in different functional departments, which also leads to the lack of centralized operation and maintenance of the secondary system of city and county dispatching, and the great difference in the degree of operation and maintenance. In addition, due to the access of distributed energy and the continuous growth of power side interaction demand, the complexity of power grid operation is increasing, which makes the dispatching operators face more and more decision pressure. Therefore, it is very important to integrate the security risk of the secondary system into the current operational risk decision-making and to make a comprehensive quantitative evaluation of it. According to the technical needs of power industry safety production monitoring, this paper puts forward an automatic system for real-time monitoring of the original secondary system, which can realize real-time data acquisition, early warning analysis and chart display in power grid, substation and production units. Graph and column diagram generation, Chinese report generation, comprehensive handling of accidents and other functions. The system platform adopts the development framework based on Flex/Extjs Struts2 spring Ibatis and uses java language to develop. After detailed requirement analysis, design and implementation, the research contents of the target system include system management, business management, computer room management, statistical analysis, abnormal alarm, real-time monitoring and collection management. In the application of target system, the information of secondary equipment and system operation parameters is monitored and collected, and according to the pre-defined alarm rules, the abnormal data is notified in real time, so that the abnormal situation can be detected and dealt with in time. For the grid security, stable operation to provide protection data. Make the whole power network production site to achieve the high level of automation of unattended, less dispatch crew on duty. The level of automation and the safety and reliability of operation are improved.
