- the collected monitoring data is divided into indicator data and log data according to different data types; real-time data and historical data are divided according to different data effectiveness; according to the data type and data effectiveness, the collected data can be collected
- the received monitoring data is divided into real-time index data and real-time log data; when data is stored, different storage methods are used according to different data; for example, real-time index data is stored in a time-series database; real-time log data is stored in full-text retrieval Library; historical monitoring data is stored in a columnar database.
- the historical data includes at least historical monitoring data.
- This type of monitoring data is stored in different types of databases, such as time series data in a time series database; log data is stored in a full-text search database; the main considerations are:
- Real-time indicator data is a series of data with time series characteristics. It can be considered that real-time indicator data is data with time stamp-time series data and should be stored in a time series database for storing time series data.
- the time-series database can store time-series data and support the fast writing and persistence of time-series data. Storing time-series data in the time-series database can realize the rapid writing of data and provide a certain basis for efficient operation and maintenance effects.
- Log data is unstructured text data that should be stored in a full-text search library.
- the full-text search database can support real-time full-text search of unstructured data.
- the full-text search database can carry a limited amount of data, so it can only store recent log data such as real-time log data.

Perform real-time monitoring and issue alarms based on corresponding alarm thresholds.
- the resource pool physical machine, virtual machine, container, storage device, network device, security device
- the dynamic threshold setting method is preferably used; if the data has no periodic characteristics after analysis, the constant threshold setting method can be used.
- the constant threshold setting method when the index set on the server side exceeds a predetermined alarm threshold range, an automatic alarm is immediately issued. It can be understood that the constant threshold setting method is to set a fixed value (alarm threshold range) for one type of monitoring data within a period of time. An alarm is generated when it is detected that the monitoring data exceeds the alarm threshold range.
- the threshold setting method of dynamic time window is adopted to solve the abnormal judgment of periodic data.
- the threshold setting method of the dynamic time window can be understood as follows. For different types of monitoring data collected, different alarm threshold ranges are automatically calculated according to the 3sigma principle. For monitoring data collected in different time periods, an alarm is generated when it exceeds the alarm threshold range calculated for the monitoring data for the corresponding time period. For example, the alarm threshold range calculated for monitoring data A based on the 3sigma principle during time period 1 is B1, and over time, the alarm threshold range calculated for monitoring data A according to the 3sigma principle during period 2 is B2 It can be understood that B2 calculated for the monitoring data A in the time period 2 should be an update of B1 according to the 3sigma principle.
- Step S4 can be regarded as a solution for implementing fault diagnosis and positioning: a multi-dimensional association analysis technology based on artificial intelligence, constructing an operation and maintenance fault diagnosis tree, quickly digging the root cause of system faults, and achieving fault diagnosis and automatic positioning;
- Fault diagnosis tree is a kind of inverted tree-like logical causality diagram, which is used to describe the causality between various events in the system.
- a fault branch is constructed according to the logical cause and effect relationship, and trees are built from top to bottom.
- the fault correlation factor of the fault branch is calculated. If the fault correlation factor is higher than the threshold (which can be regarded as a fault threshold), it is added to the fault tree; if the fault correlation factor is lower than the threshold, the fault correlation factor is calculated. It is removed from the fault tree.
- the threshold which can be regarded as a fault threshold
- the O & M fault diagnosis tree is intuitive, clear, clear in thinking, and logical. Automatic positioning can improve the efficiency and accuracy of automatic fault location, improve the intelligent level of system operation and maintenance, and reduce system operation and maintenance costs.
- the hardware, middleware, and application system monitoring data in the power grid dispatching control system are displayed visually through a variety of visualization methods (graphics, tables, dashboards), from the entire network to specific equipment, from comprehensive information display to important node monitoring, Multi-dimensional and multi-level visual display of operation and maintenance data enables regulators to quickly and accurately judge whether the automation equipment and systems of the entire network are operating normally from the visualized operation and maintenance graphics, and timely grasp the dangerous points of system operation and the existing operational risks.

本申请实施例提供一种基于电网调度的运维方法、具体涉及一种基于电网调度控制系统的智能运维架构设计方法,包括以下步骤:The embodiment of the present application provides an operation and maintenance method based on power grid dispatching, and particularly relates to a method for designing an intelligent operation and maintenance architecture based on power grid dispatching control system, including the following steps:
S1,全方位采集运维监控数据:至少采集电网调度控制系统的硬件设备和系统软件的监控数据;S1. Comprehensive collection of operation and maintenance monitoring data: at least the monitoring data of hardware equipment and system software of the power grid dispatching control system;
S2,存储监控数据:至少依据所采集的监控数据的数据类型和/或数据实效性,确定所采集的监控数据的存储方式,并以所确定的存储方式对所采集的监控数据进行存储;S2. Store monitoring data: at least according to the data type and / or data effectiveness of the collected monitoring data, determine the storage method of the collected monitoring data, and store the collected monitoring data in the determined storage method;
如图2所示,采集到的监控数据根据数据类型的不同划分为指标数据和日志数据;根据数据实效性的不同分为实时数据和历史数据;根据数据类型和数据实效性,可将所采集到的监控数据划分为实时指标数据和实时 日志数据;在进行数据存储时,根据数据的不同采用不同的存储方式;例如,将实时指标数据存储在时序数据库中;将实时日志数据存储在全文检索库中;历史监控数据存储在列式数据库中。其中,所述历史数据至少包括历史监控数据。As shown in Figure 2, the collected monitoring data is divided into indicator data and log data according to different data types; real-time data and historical data are divided according to different data effectiveness; according to the data type and data effectiveness, the collected data can be collected The received monitoring data is divided into real-time index data and real-time log data; when data is stored, different storage methods are used according to different data; for example, real-time index data is stored in a time-series database; real-time log data is stored in full-text retrieval Library; historical monitoring data is stored in a columnar database. The historical data includes at least historical monitoring data.
这种将不同监控数据存储到不同类型的数据库中,例如将时序数据存储到时序数据库中;将日志数据存储到全文检索库中;主要是考虑到:This type of monitoring data is stored in different types of databases, such as time series data in a time series database; log data is stored in a full-text search database; the main considerations are:
实时指标数据是具有时序特征的一系列数据,可以认为实时指标数据是带有时间戳的数据-时序数据,应该存储在用于存储时序数据的时序数据库中。时序数据库能够存储时序数据,支持时序数据的快速写入、持久化;将时序数据存储到时序数据库中,可实现数据的快速写入,为高效的运维效果提供了一定的依据。Real-time indicator data is a series of data with time series characteristics. It can be considered that real-time indicator data is data with time stamp-time series data and should be stored in a time series database for storing time series data. The time-series database can store time-series data and support the fast writing and persistence of time-series data. Storing time-series data in the time-series database can realize the rapid writing of data and provide a certain basis for efficient operation and maintenance effects.
日志数据是非结构化的文本数据应存储到全文检索库中。全文检索库能够支持非结构化数据的全文实时检索。通常全文检索库能够承载的数据量有限,因此其只能存放近期的日志数据例如实时日志数据。Log data is unstructured text data that should be stored in a full-text search library. The full-text search database can support real-time full-text search of unstructured data. Usually the full-text search database can carry a limited amount of data, so it can only store recent log data such as real-time log data.
对于历史监控数据,其数量较大,需要存放到大容量的列式数据库中,以方便后续的大规模数据处理。For historical monitoring data, the quantity is large and needs to be stored in a large-capacity columnar database to facilitate subsequent large-scale data processing.
S3,对监控数据进行检测,获得异常指标数据;S3. Detect monitoring data to obtain abnormal index data;
实时监控告警:采用恒定阈值(设定)法与动态阈值(设定)法进行实时监控告警,检测系统的异常指标数据;Real-time monitoring and alarming: constant threshold (setting) method and dynamic threshold (setting) method are used for real-time monitoring and alarming to detect abnormal index data of the system;
相关技术中,监控告警配置基本靠运维工程师经验或持续的迭代修正,甚至纯人工排查。本申请实施例中,通过制定监控标准和自动化监控部署实现运维监控的标准化和自动化,以实现智能化告警。In related technologies, the configuration of monitoring alarms basically depends on the experience of operation and maintenance engineers or continuous iterative corrections, or even pure manual troubleshooting. In the embodiments of the present application, the standardization and automation of operation and maintenance monitoring are achieved through the development of monitoring standards and automatic monitoring deployment, so as to implement intelligent alarms.
在步骤S1和S2中,通过对资源池(物理机、虚拟机、容器、存储设备、网络设备、安防设备)、平台、数据库及应用系统运行监控数据的采集,对电网调度控制系统的运行状态进行实时监视,并基于相应的告警阈值发出 告警。In steps S1 and S2, the operation status of the power grid dispatching control system is collected by collecting the operation monitoring data of the resource pool (physical machine, virtual machine, container, storage device, network device, security device), platform, database, and application system. Perform real-time monitoring and issue alarms based on corresponding alarm thresholds.
在系统出现指标数据波动时,需要先判定是否确实为异常情况,确定异常后再实现精准报警。自动检测业务的异常指标,主要有两种方法:恒定阈值设定法与动态阈值设定法。When the indicator data fluctuates in the system, it is necessary to first determine whether it is indeed an abnormal situation, and then implement an accurate alarm after determining the abnormality. There are two main methods for automatically detecting abnormal indicators of business: constant threshold setting method and dynamic threshold setting method.
需要说明的是,如果监控数据为具有很强的周期性特征的数据,则优选使用动态阈值设定法;如果数据经分析后没有周期性特征,则可以使用恒定阈值设定法。It should be noted that if the monitoring data is data with strong periodic characteristics, the dynamic threshold setting method is preferably used; if the data has no periodic characteristics after analysis, the constant threshold setting method can be used.
其中,恒定阈值设定法:在服务器端设定的指标超过预定告警阈值范围时立刻自动报警。可以理解,恒定阈值设定法即为在一段时间内为一种类型的监控数据设定一个固定的数值(告警阈值范围)。在检测到该监控数据超过告警阈值范围时产生告警。Among them, the constant threshold setting method: when the index set on the server side exceeds a predetermined alarm threshold range, an automatic alarm is immediately issued. It can be understood that the constant threshold setting method is to set a fixed value (alarm threshold range) for one type of monitoring data within a period of time. An alarm is generated when it is detected that the monitoring data exceeds the alarm threshold range.
动态阈值设定法:采用动态时间窗口的阈值设定法来解决周期性数据的异常判断。动态时间窗口的阈值设定法可以这样理解,对于采集到的同一类型监控数据,在不同的时间段,依据3sigma原则自动计算出不同的告警阈值范围。针对在不同时间段采集的监控数据,当其超过为对应时间段为该监控数据计算出的告警阈值范围时,产生告警。举个例子,在时间段1内依据3sigma原则为监控数据A计算出的告警阈值范围为B1,随着时间的推移,在时间段2依据3sigma原则为监控数据A计算出的告警阈值范围为B2,可以理解在时间段2内为监控数据A计算出的B2应该是依据3sigma原则对B1进行的更新。Dynamic threshold setting method: The threshold setting method of dynamic time window is adopted to solve the abnormal judgment of periodic data. The threshold setting method of the dynamic time window can be understood as follows. For different types of monitoring data collected, different alarm threshold ranges are automatically calculated according to the 3sigma principle. For monitoring data collected in different time periods, an alarm is generated when it exceeds the alarm threshold range calculated for the monitoring data for the corresponding time period. For example, the alarm threshold range calculated for monitoring data A based on the 3sigma principle during time period 1 is B1, and over time, the alarm threshold range calculated for monitoring data A according to the 3sigma principle during period 2 is B2 It can be understood that B2 calculated for the monitoring data A in the time period 2 should be an update of B1 according to the 3sigma principle.
S4,基于对异常指标数据的多维度关联分析,构建运维故障诊断树,至少对产生异常指标数据的故障进行诊断和定位;S4. Based on multi-dimensional correlation analysis of abnormal index data, construct an operation and maintenance fault diagnosis tree, and at least diagnose and locate faults that generate abnormal index data;
步骤S4中即可视为实现故障诊断与定位的方案:基于人工智能的多维度关联分析技术,构建运维故障诊断树,快速挖掘系统故障根源,实现故障诊断与自动定位;Step S4 can be regarded as a solution for implementing fault diagnosis and positioning: a multi-dimensional association analysis technology based on artificial intelligence, constructing an operation and maintenance fault diagnosis tree, quickly digging the root cause of system faults, and achieving fault diagnosis and automatic positioning;
面对电网调度控制系统中的海量运维数据,需充分考虑运维数据的时间、空间和应用多维度特性和运维数据与其他因素之间复杂的关联关系,如图3所示,利用多维度关联分析,从多个维度对运维数据进行关联分析、信息钻取,找出与故障有强关联关系的运维指标,采用基于逻辑的方法构建运维故障诊断树。故障诊断树是一种倒立树状逻辑因果关系图,用于描述系统中各种事件之间的因果关系。在选定某一系统故障后,根据造成故障的原因按逻辑因果关系构建故障支路,并自顶向下逐级建树。为避免故障树过于复杂,计算故障支路的故障关联因子,若故障关联因子高于阈值(可视为一种故障阈值),则将其加入故障树;若故障关联因子低于阈值,则将其从故障树中去除。Facing the massive operation and maintenance data in the power grid dispatching control system, it is necessary to fully consider the time, space, and application of the multidimensional characteristics of the operation and maintenance data and the complex relationship between the operation and maintenance data and other factors, as shown in Figure 3. Dimensional correlation analysis, which analyzes the operation and maintenance data from multiple dimensions, drills down the information, finds the operation and maintenance indicators that have a strong correlation with the fault, and uses a logic-based method to construct the operation and maintenance fault diagnosis tree. Fault diagnosis tree is a kind of inverted tree-like logical causality diagram, which is used to describe the causality between various events in the system. After selecting a certain system fault, according to the cause of the fault, a fault branch is constructed according to the logical cause and effect relationship, and trees are built from top to bottom. In order to avoid the fault tree being too complicated, the fault correlation factor of the fault branch is calculated. If the fault correlation factor is higher than the threshold (which can be regarded as a fault threshold), it is added to the fault tree; if the fault correlation factor is lower than the threshold, the fault correlation factor is calculated. It is removed from the fault tree.
其中,运维故障诊断树具有直观、明了,思路清晰,逻辑性强的特点,能够进行定性分析,本申请实施例通过对运维故障诊断树的使用,可实现快速挖掘系统故障根源和实现故障自动定位,能够提高系统故障自动定位的效率和正确率,提升系统运维的智能化水平,降低系统运维成本。Among them, the O & M fault diagnosis tree is intuitive, clear, clear in thinking, and logical. Automatic positioning can improve the efficiency and accuracy of automatic fault location, improve the intelligent level of system operation and maintenance, and reduce system operation and maintenance costs.
