技术领域technical field
本发明涉及电力调度自动化技术领域，特别涉及一种调度运行信息巡检方法及系统。The invention relates to the technical field of power dispatching automation, in particular to a dispatching operation information inspection method and system.
背景技术Background technique
随着电力系统大运行体系的不断推进、智能变电站建设速度的加快，监控信息接入量呈急剧增长，监控人员需要在大量的信号中提取出重要的故障信息。With the continuous advancement of the large-scale operation system of the power system and the acceleration of the construction of smart substations, the amount of monitoring information access has increased sharply, and monitoring personnel need to extract important fault information from a large number of signals.
目前，在电力系统中一般使用OPEN3000调度自动化监控系统来显示告警信息，以便监控人员进行重要信息提取。但是OPEN3000调度自动化监控系统是刷屏式的根据时间顺序显示这些告警信息，即使通过消息分层机制进行不用告警信息的分类，不同的告警页面依然会被大量的告警信息刷屏。这种刷屏式显示告警信息存在的缺陷如下：At present, the OPEN3000 scheduling automation monitoring system is generally used in the power system to display alarm information so that monitoring personnel can extract important information. However, the OPEN3000 scheduling automation monitoring system displays these alarm information in a chronological order by swiping the screen. Even if the alarm information is not classified through the message layering mechanism, different alarm pages will still be swiped by a large number of alarm information. The defects of this kind of swiping screen display alarm information are as follows:
一是，在巨量告警信息中存在大量的无效信号，严重干扰了监控人员对重要信息的提取。而且OPEN3000调度自动化监控系统的告警页面存在这消息分类粗糙的问题，将各种量测值的越线信息统统划分为“越限信息”并进行显示，在巨量信息下，很难保证可以在第一时间关注到关键的量测事故信息。因此，监控人员通过OPEN3000调度自动化监控系统确认各种告警信息的难度较大。First, there are a large number of invalid signals in the huge amount of alarm information, which seriously interferes with the extraction of important information by monitoring personnel. Moreover, the alarm page of the OPEN3000 scheduling automation monitoring system has the problem of rough message classification. The cross-line information of various measured values is divided into "limit information" and displayed. Under the huge amount of information, it is difficult to ensure that the Pay attention to the key measurement accident information at the first time. Therefore, it is difficult for monitoring personnel to confirm various alarm information through the OPEN3000 dispatching automation monitoring system.
二是，OPEN3000调度自动化监控系统对于发电厂和变电站上传的数据长时间不发生变化的情况，缺乏告警手段，仅能凭借监控人员进行人工核查，浪费人力。The second is that the OPEN3000 dispatching automation monitoring system lacks warning means for the situation that the data uploaded by power plants and substations does not change for a long time. It can only rely on monitoring personnel to conduct manual verification, which is a waste of manpower.
三是，OPEN3000调度自动化监控系统缺少对多线路负荷重载、打压机过载、母线电压波动、母线单相接地等重要信息的告警。监控人员仅能凭借人工查询历史数据和现场电话汇报进行确认，严重影响了监控人员和调度人员进行相应调度处理的实时性。Third, the OPEN3000 dispatch automation monitoring system lacks alarms for important information such as multi-line load overload, compressor overload, bus voltage fluctuation, and bus single-phase grounding. Monitoring personnel can only confirm by manually querying historical data and on-site telephone reports, which seriously affects the real-time performance of monitoring personnel and dispatchers for corresponding scheduling processing.
四是，OPEN3000调度自动化监控系统的告警文字信息使用滚动式的提示方式，相当于历史信息浏览，仅能反应事故或异常信息曾经发生过，不能反应当前造成告警的原因是否依然存在。而且，在监控人员交接班时，接班人员无法查看当前依然处于告警状态的全部告警信号。Fourth, the alarm text information of the OPEN3000 dispatch automation monitoring system uses a scrolling prompt method, which is equivalent to historical information browsing, which can only reflect the occurrence of accidents or abnormal information, and cannot reflect whether the current cause of the alarm still exists. Moreover, when the monitoring personnel change shifts, the successor cannot check all the alarm signals that are still in the alarm state.
五是，OPEN3000调度自动化监控系统对与常规设备以外的测量值，不能针对进行同类型设备的告警配置，只能针对每个非常规量测值，单独配置告警限制或告警信息，不能针对同种类型的非常规设备，进行统一的告警策略配置。Fifth, the OPEN3000 scheduling automation monitoring system cannot configure alarms for the same type of equipment for measurement values other than conventional equipment. It can only configure alarm limits or alarm information for each unconventional measurement value, and cannot target the same type of equipment. For unconventional devices of different types, a unified alarm policy configuration is performed.
六是，OPEN3000调度自动化监控系统中缺少合理的数据有效性判断策略，仅有“不变化”、“跳变”、“无效”、“可疑”、“封锁”、“正常”、“置数”、“取状态估计”、“计算值”、“可疑”这些描述数值本身有效性的状态判断，不能根据厂站实际状态，进行整体的数值有效性判断及推导。Sixth, the OPEN3000 scheduling automation monitoring system lacks a reasonable data validity judgment strategy, only "no change", "jump", "invalid", "suspicious", "blocked", "normal", "set number" , "Estimation of State", "Calculated Value", and "Suspicious" state judgments that describe the validity of the value itself cannot be used to judge and deduce the validity of the overall value based on the actual state of the station.

具体地，以合肥地区为例，将合肥地区内所有发电厂与变电站内设备连接方式及设备连接顺序的变电站模型如图2所示。Specifically, taking the Hefei area as an example, the substation model of the equipment connection methods and equipment connection sequences of all power plants and substations in the Hefei area is shown in Figure 2.
进一步地，上述步骤S3，具体包括如下步骤：Further, the above step S3 specifically includes the following steps:
判断厂站与OPEN3000主站网络之间的连接是否正常，若正常连接则确定该厂站内数据有效，若连接中断则确定该厂站内数据均为无效数据；Judging whether the connection between the factory station and the OPEN3000 master station network is normal, if the connection is normal, it is determined that the data in the factory station is valid, and if the connection is interrupted, it is determined that the data in the factory station is invalid data;

具体地，变异系数的计算过程包括：Specifically, the calculation process of the coefficient of variation includes:
计算n次取出的量测数据的平均值：其中n为取值总次数，i为第几次取值，xi为取出的测量数据，为n次取值得到的量测数据的平均值；Calculate the average value of the measured data taken out n times: Among them, n is the total number of times to take values, i is the number of times to take values, xi is the measured data taken out, It is the average value of the measured data obtained by taking n values;

具体地，在实际应用中，当量测数据类型为电压数据、电流数据、有功数据、无功数据或者温度数据时，需要采用约束条件对量测数据进行约束，具体为：Specifically, in practical applications, when the measurement data type is voltage data, current data, active data, reactive data or temperature data, it is necessary to use constraints to constrain the measurement data, specifically:
当x为电压数据时，Ulow＜x＜Uhigh，其中Ulow为电压理论下限，Uhigh为电压理论上限，由母线额定电压决定。When x is the voltage data, Ulow <x<Uhigh , where Ulow is the theoretical lower limit of the voltage, and Uhigh is the theoretical upper limit of the voltage, which is determined by the rated voltage of the bus.
当x为电流数据时，1.01≤x≤Ihigh，其中Ihigh为电流理论上限，由设备类型决定。When x is the current data, 1.01≤x≤Ihigh , where Ihigh is the theoretical upper limit of the current, which is determined by the device type.

当x为温度数据时，0≤|x|≤98。When x is temperature data, 0≤|x|≤98.
需要说明的是，在上述类型的量测数据不符合约束条件时视作无效数据。当x为其他类型的量测数据时，不进行约束。It should be noted that when the above-mentioned types of measurement data do not meet the constraint conditions, they are regarded as invalid data. When x is other types of measurement data, no constraints are imposed.
进一步地，根据变异系数C判断量测数据的有效性的判断条件为：CL≤C≤CH，其中CL为该类型量测数据的变异度下限，CH为该类型量测数据变异度上限。其中：Furthermore, the judgment condition for judging the validity of the measurement data according to the coefficient of variation C is: CL ≤ C ≤CH , whereCL is the lower limit of the variability of this type of measurement data, and CH is the variation of this type of measurement data upper limit. in:
当x为电压数据时，CL＝85％，CH＝117％；When x is voltage data, CL =85%,CH =117%;
当x为电流数据时，CL＝50％，CH＝200％；When x is current data, CL =50%,CH =200%;
当x为有功数据时，CL＝80％，CH＝120％；When x is active data, CL =80%,CH =120%;
当x为无功数据时，CL＝80％，CH＝120％；When x is reactive data, CL =80%,CH =120%;
当x为其他类型数据时，CL＝0.01％，CH＝+∞。When x is other types of data, CL =0.01%,CH =+∞.
当时，说明K个变异系数不发生变化，直接发出量测数据不变化警告，其中，为K个变异系数的平均数，Ck为第k个变异系数。when When , it means that the K variation coefficients do not change, and a warning is issued directly that the measurement data does not change. Among them, is the average number of K coefficients of variation, and Ck is the kth coefficient of variation.
进一步地，步骤S4中告警评估策略具体为：Further, the alarm evaluation strategy in step S4 is specifically:
当x为有功、无功、电压、电流或其他有效量测数据时，告警评估策略为：When x is active power, reactive power, voltage, current or other valid measurement data, the alarm evaluation strategy is:
其中，xL为告警下限值，xH为告警上限值，TL为越限持续时间阈值，T为越限后的持续时间，RL为上次告警时间，Tnow为当前时间，R为再次告警时间阈值；Among them, xL is the lower limit value of the alarm, xH is the upper limit value of the alarm, TL is the duration threshold of the limit violation, T is the duration after the limit violation,RL is the last alarm time, Tnow is the current time, R is the re-alarm time threshold;
所述的变电站内开关开合数据的告警评估策略为：The alarm evaluation strategy for the switch opening and closing data in the substation is as follows:
其中，开关开合数据为断路器、刀闸、接地刀闸以及保护信号等开关的开合数据，Ad为开关动作次数阈值，Asum为规定时间段内的开关动作次数，Td为开关合位持续时间阈值，Tc为开关合位持续时间，Tsxz为统计时间段上界，Tuxz为统计时间段下界，RL为上次告警时间，Tnow为当前时间，R为再次告警阈值。Among them, the switch opening and closing data are the opening and closing data of switches such as circuit breakers, knife switches, grounding knife switches, and protection signals, Ad is the threshold value of the number of switching operations, Asum is the number of switching operations within a specified period of time, and Td is the switch Threshold of closing duration, Tc is the duration of switch closing, Tsxz is the upper bound of the statistical time period, Tuxz is the lower bound of the statistical time period,RL is the time of the last alarm, Tnow is the current time, R is the alarm again threshold.
进一步地，根据上述告警评估策略评估后的告警信息，然后根据不同的告警类别将告警信息进行分类，并推送至工作站，在告警界面进行显示。Further, the alarm information evaluated according to the above alarm evaluation strategy is then classified according to different alarm categories, and pushed to the workstation for display on the alarm interface.
需要说明的是，本实施例中告警信息在告警页面的显示方式具体为：发生时间--告警类别--告警厂站--告警设备名称--告警原因。其中告警文字信息有10秒的文字闪烁提示，并播放对应的电子合成告警类别语音提示和电子合成告警厂站语音提示，告警信息在数据恢复正常后，会自动消失，在告警尚未消失或未进行人工消除的情况下，始终驻留在告警界面的第一页，以提醒监控人员及时进行事故处理，避免告警信息漏处理的情况。It should be noted that, in this embodiment, the display mode of the alarm information on the alarm page is specifically: occurrence time--alarm category--alarm station--alarm device name--alarm reason. Among them, the alarm text information has a 10-second text flashing prompt, and the corresponding electronic synthesis alarm category voice prompt and electronic synthesis alarm factory station voice prompt are played. The alarm information will disappear automatically after the data returns to normal. In the case of manual elimination, it always stays on the first page of the alarm interface to remind the monitoring personnel to deal with the accident in time to avoid the situation of missing alarm information.
下面以对合肥地区的电网告警信息为例进行分析说明：The following takes the power grid warning information in Hefei as an example to analyze and explain:
通过对目前使用的OPEN3000系统的运行记录进行排查，得知造成电压电流频发越限的主要原因是：某些变电站的电压电流有功负荷等数据经常处于临近上限的运行状态，这种情况下系统会频发越限信号，造成频发越限，同时变电站的检修调试也造成了无效越限信息。Through the investigation of the operation records of the currently used OPEN3000 system, it is known that the main reason for the frequent violation of the voltage and current is that the voltage, current, active load and other data of some substations are often in the operating state close to the upper limit. In this case, the system Frequent limit violation signals will be sent, resulting in frequent limit violations. At the same time, the maintenance and debugging of substations will also cause invalid limit violation information.
本实施例中针对不同设备进行限值调整，使用添加延时的方法去除频发抖动造成的告警.In this embodiment, the limit value is adjusted for different devices, and the method of adding delay is used to remove the alarm caused by frequent jitter.
其中，延时设置可如下表1所示：Among them, the delay setting can be shown in Table 1 below:
表1Table 1
增加新的母线每日电压波动告警情况如下表2所示，防止母线每日电压最大值与最小值差异过大引起事故：Add a new busbar daily voltage fluctuation alarm situation as shown in Table 2 below to prevent accidents caused by excessive differences between the busbar daily voltage maximum and minimum values:
表2Table 2
增加电流突变告警显示，使监控人员可以及时发现系统中的电流突变信息，告警显示条件如表3所示：Increase the current mutation alarm display, so that the monitoring personnel can find the current mutation information in the system in time. The alarm display conditions are shown in Table 3:
表3table 3
本实施例根据实际需要使用延时的方法去除频发抖动造成的大量无效告警信息，减少了干扰告警信息，降低了监控人员的工作量。同时增加的新的告警方式比如母线电压波动告警等，符合实际电网运行的需求，提高了告警信息筛选的准确性和覆盖面。According to actual needs, this embodiment uses a delay method to remove a large amount of invalid alarm information caused by frequent jittering, reduces interference alarm information, and reduces the workload of monitoring personnel. At the same time, new alarm methods such as bus voltage fluctuation alarm are added, which meet the needs of actual power grid operation and improve the accuracy and coverage of alarm information screening.
