Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The method for generating the regional power grid control report can be applied to an application environment shown in fig. 1. Wherein the dispatch terminal 11 communicates with the server 12 via a network. The server 12 acquires the real-time operation frequency of the regional power grid from the dispatching terminal 11; if the server 12 detects that the fluctuation range of the real-time operating frequency does not belong to the preset fluctuation range, determining a target power equipment cluster causing frequency fluctuation from the regional power grid; the server 12 obtains control instruction information generated by a scheduling mechanism for scheduling the target power equipment cluster; the server 12 checks the control instruction issued by the scheduling mechanism to the target power equipment cluster according to the control instruction information; the server 12 generates a regional power grid control report corresponding to the dispatching mechanism according to the verification result.
The dispatch terminal 11 may be, but not limited to, a variety of platforms, personal computers, notebook computers, smartphones, tablet computers, etc. each of which is equipped with a power dispatching system or can be communicatively connected to the power dispatching system, and the server 12 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a method for generating a regional power grid control report is provided, and the method is applied to the server 12 in fig. 1 for illustration, and includes the following steps:
and step 21, acquiring the real-time operating frequency of the regional power grid.
The power grid can be divided according to geographic positions to obtain a plurality of regional power grids; each regional power grid is composed of a single power device or a cluster of power devices obtained by integrating a plurality of power devices.
Specifically, the server is in communication connection with the dispatching terminal, and receives real-time operation frequency of the regional power grid controlled by the dispatching terminal, wherein the real-time operation frequency is acquired by the dispatching terminal; the scheduling terminal may update the operating frequency to the server in real time, or may periodically update the operating frequency to the server.
The dispatching terminal can acquire the real-time frequency of the regional power grid and also acquire the environmental information, such as temperature, humidity, pressure value and the like, of each power equipment or power equipment clusters in the regional power grid.
In the step, the server is connected with the dispatching terminal, so that the real-time operating frequency of the regional power grid acquired by the dispatching terminal can be acquired, the acquisition efficiency of the regional power grid frequency data can be improved through unified acquisition of the dispatching terminal, and the acquisition efficiency of the data required by report generation is improved.
Step 22, if the fluctuation range of the real-time operation frequency is detected not to belong to the preset fluctuation range, determining a target power equipment cluster causing frequency fluctuation from the regional power grid.
The preset fluctuation range is a fluctuation limit value set for the real-time operation frequency of the regional power grid, and when the fluctuation range of the operation frequency exceeds the fluctuation range of the frequency, the condition that the frequency of the regional power grid is abnormal is indicated; for example, the preset variation range is within plus or minus 20, and the server detects that the variation range of the real-time operation frequency is plus 30, then it can be determined that the variation range of the real-time operation frequency exceeds the preset variation range, that is, does not belong to the preset variation range. The preset variation range can be directly set as the frequency, and can also be set as a related index of the real-time frequency of the regional power grid, such as an average frequency value, a median frequency value, a variance and the like in a certain period of time.
The detection of the real-time operation frequency variation can be specifically performed by the following aspects: 1) Judging whether the frequency is suddenly changed or not, and judging whether the difference value of the frequency sampling points in the continuous time (for example, set to 2 seconds) is larger than a fixed value or not; 2) Judging whether the frequency deviation is larger than a specified value or not according to whether the difference between the actual frequency value and the rated value is larger than a fixed value or not; 3) Judging whether the time when the frequency is at the high frequency or the low frequency for a certain time is larger than a fixed value of the high frequency or smaller than the fixed value of the low frequency continuously according to the frequency; 4) The frequency continuously fluctuates between the high frequency and the low frequency, and whether the time period and the fluctuation amplitude according to the frequency fluctuation are respectively larger than the fixed value is judged.
The target power equipment cluster refers to power equipment or power equipment cluster which is determined by a server from a regional power grid and causes the frequency change.
For example, a certain regional power grid has 3 power device clusters A, B, C in total, the overall frequency variation range index of the regional power grid is 10, the frequency variation range index of the power device cluster a is found to be 5 after the detection of the server, and the frequency variation index of the power device cluster B, C is found to be 1, so that the server can determine the power device cluster a as the target power device cluster causing the frequency variation in the regional power grid.
Further, if the server can acquire the real-time frequency of each power device in the power device cluster a from the scheduling terminal, the server can further identify the target power device causing the frequency fluctuation from the power device cluster a. The determining of the target power device cluster or the target power device may be one or a plurality of the target power devices, and may be specifically determined according to a specific influence of the frequency variation caused by the target power device cluster or the target power device.
In the step, the target power equipment cluster causing the frequency fluctuation is identified from the regional power grid by detecting the abnormal frequency change, so that the range of the abnormal power equipment can be rapidly locked, the data processing amount is reduced, and the generation efficiency of the regional power grid control report and the timeliness of monitoring the abnormal frequency of the regional power grid are greatly improved.
And step 23, obtaining control instruction information generated by a scheduling mechanism for scheduling the target power equipment cluster.
The control instruction information is data information generated by a dispatching mechanism when dispatching the power equipment or the power equipment cluster, and all information related to the control instruction can be obtained from the control instruction information, such as specific control instruction content, sending time of the control instruction, and executing conditions of the control instruction returned by the sender, the power equipment or the power equipment cluster; the control command information corresponds to a log file when the scheduling means performs scheduling, and the server can analyze the cause of the abnormality of the target power equipment cluster that causes the frequency fluctuation from the control command information.
The control instruction information also includes overall operation state information of the regional power grid, for example: analyzing the running state of the regional power grid, including load level, regional power grid frequency, regional total active power change condition and the like; step two, analyzing the direct current transmission state, and comparing the direct current transmission tie line power with the system frequency; analyzing the automatic gain control state, including whether the automatic gain control has abnormal alarm or not and which power equipment or power equipment clusters are put into the automatic gain control function; fourthly, analyzing control instructions of a PLC (Programmable Logic Controller, a programmable logic controller) to judge whether an automatic gain control instruction of the PLC of the power plant is reasonable; fifthly, analyzing the power plant active power regulation, and judging whether the power plant automatic gain control output has the condition of increasing frequency fluctuation.
Specifically, the server first determines a specific scheduling mechanism or scheduling terminal corresponding to the target power equipment cluster; and acquiring control instruction information which is generated and stored when the scheduling mechanism or the scheduling terminal performs scheduling operation from the scheduling mechanism or the scheduling terminal. If the server obtains the direct control instruction information, the server can generate corresponding control instruction information by summarizing logs, instruction sending records and the like of the dispatching mechanism.
According to the method, the control instruction information generated by scheduling the target power equipment cluster is obtained, the running states of the target power equipment cluster and the scheduling mechanism can be judged based on the control instruction information, the problem is found out, and the generation efficiency of the regional power grid control report and the timeliness of monitoring the abnormal frequency of the regional power grid are improved.
And step 24, checking the control instruction issued by the scheduling mechanism to the target power equipment cluster according to the control instruction information.
Specifically, the server can acquire a control instruction issued by the scheduling mechanism to the target power equipment cluster according to the control instruction information; the control instruction can be checked according to the control instruction, and the result of executing the control instruction by the target power equipment cluster can also be checked, so that the reason for causing the abnormal real-time running frequency is judged according to the check result.
Checking the control instruction includes: the method comprises the steps of firstly, determining which power equipment or power equipment clusters are put into an automatic gain control mode of a dispatching mechanism; reading an automatic gain control instruction received by the power equipment or the power equipment cluster during the abnormal frequency period; thirdly, determining whether to increase or decrease the power command by comparing the actual power output of the power equipment or the power equipment cluster according to each automatic gain control command; and fourthly, determining the correctness of the automatic gain control instruction logic aspect of the dispatching mechanism by judging whether the power equipment or the power equipment cluster receives the decreasing force instruction at high frequency and whether the power equipment or the power equipment cluster receives the increasing force instruction at low frequency.
For example, after checking the control instruction, the server finds that the target power equipment cluster normally executes the control instruction, and the execution result accords with the expectation of the control instruction, so that the abnormality of the target power equipment cluster can be eliminated; the triggering control instruction of the dispatching mechanism is checked, and the fact that the dispatching mechanism has errors in data calculation is found, so that the predicted frequency of the target power equipment cluster in the next time period is wrongly judged, and the wrong control instruction is issued; the server checks the control command based on the control command information, and judges the object except the problem and the specific reason of the problem.
According to the method, the server can verify the control instruction issued by the scheduling mechanism to the target power equipment cluster through the control instruction information, so that an abnormality generation object and a specific reason are quickly identified, and the generation efficiency of a regional power grid control report and the timeliness of monitoring the regional power grid abnormal frequency are improved.
And step 25, generating a regional power grid control report corresponding to the dispatching mechanism according to the verification result.
Specifically, the server can output the verification result in the form of a report; the server determines an object generated by the abnormality and a specific abnormality reason according to the verification result, acquires corresponding data from the object generated by the abnormality, and correspondingly fills the corresponding data into a preset regional power grid control report template.
The server may employ a java-based poi-tl (poi template language, word template engine); POI-tl is a Word template engine based on Apache POI, and Word documents can be generated according to a specified format, and Word content generally comprises the following aspects:
1) The event overview is used for showing the abnormal time of the regional power grid frequency, the regional control error (ACE), the maximum and minimum frequency values, the regional power grid frequency diagram and the like; 2) The system load and the delivery change condition are used for displaying the output change of the high-capacity power plant and the active-frequency comparison condition of the whole network and the delivery line; 3) The event is used for displaying a target power equipment cluster and/or the active frequency comparison condition and the Automatic Gain Control (AGC) instruction execution condition of the target power equipment; 4) An Automatic Gain Control (AGC) action condition for exhibiting an Automatic Gain Control (AGC) failure condition during a frequency anomaly.
The step server generates the regional power grid control report corresponding to the dispatching mechanism according to the verification result, can summarize the data and automatically generate the corresponding report, does not need to manually arrange and sort the data, and improves the generation efficiency of the regional power grid control report.
In the above method for generating a regional power grid control report, the method includes: acquiring real-time operating frequency of a regional power grid; if the fluctuation range of the real-time operating frequency is detected not to belong to the preset fluctuation range, determining a target power equipment cluster causing frequency fluctuation from the regional power grid; control instruction information generated by scheduling the target power equipment cluster by a scheduling mechanism is obtained; according to the control instruction information, verifying a control instruction issued by the scheduling mechanism to the target power equipment cluster; and generating a regional power grid control report corresponding to the dispatching mechanism according to the verification result. The method comprises the steps of monitoring the running frequency of a power grid in real time, identifying a target power equipment cluster generating abnormality after the abnormality is detected, checking an instruction sent to the target power equipment cluster by a related scheduling mechanism, judging whether logic of the instruction issued by the scheduling mechanism is correct or not, and generating a corresponding control report; the method and the device can identify the abnormality and generate the report at the first time without manually collecting, analyzing and confirming the data, so that the generation efficiency of the regional power grid control report and the timeliness of monitoring the abnormal frequency of the regional power grid are greatly improved.
In one embodiment, as shown in fig. 3, if it is detected that the range of the real-time operating frequency does not belong to the preset range, the method includes:
step 31, performing feature extraction processing on the real-time operation frequency of the regional power grid to obtain a plurality of frequency variation indexes;
and step 32, comparing the frequency variation indexes with preset frequency variation values in the preset frequency variation value group respectively, if the frequency variation indexes are larger than the preset frequency variation values, determining that the variation range of the real-time running frequency exceeds the preset frequency variation values, and taking the regional power grid as a target regional power grid.
The method comprises the steps that a plurality of frequency variation indexes obtained through feature extraction processing can be used for reflecting the variation degree of the whole regional power grid in different aspects of frequency; the preset frequency variation value group consists of a plurality of preset frequency variation values, and each preset frequency variation value corresponds to the frequency variation index. The target regional power grid is a regional power grid with the problem of abnormal frequency determined after the real-time operation frequency monitoring is carried out on a plurality of regional power grids, and plays a role in quick positioning.
Specifically, the server performs feature extraction processing on the real-time operating frequency of the regional power grid according to features such as time, frequency fluctuation range, frequency fluctuation increase and decrease range and the like to obtain a plurality of frequency fluctuation indexes; and acquiring a preset frequency variation value group from a preset database, respectively comparing each frequency variation index with a corresponding preset frequency variation value in the preset frequency variation value group, and determining the target regional power grid according to a comparison result.
According to the embodiment, the frequency variation index is compared with the preset frequency variation value, whether the variation range of the real-time operation frequency exceeds the preset frequency variation value is determined according to the comparison result, and then the regional power grid with abnormal frequency is screened out to serve as a target regional power grid; the method has the advantages that the screening is carried out in the form of areas, the target area power grid can be rapidly determined, and the data range is reduced; the integral running state and trend of each regional power grid can be better represented through indexes.
In one embodiment, as shown in fig. 4, determining a target power device cluster causing a frequency variation from a regional power grid includes:
step 41, identifying each power equipment cluster in the target area power grid;
step 42, determining a correlation value between each power equipment cluster and the target area power grid frequency variation;
step 43, using the power equipment cluster with the correlation value exceeding the preset threshold as the target power equipment cluster causing frequency variation in the regional power grid.
Specifically, the server may directly obtain the power equipment cluster existing in the target regional power grid according to the pre-stored regional power grid data, or may send a request to a console of the target regional power grid to obtain the power equipment cluster information contained in the console.
The frequency fluctuation between the power equipment clusters and the target regional power grid has correlation, but the contribution of different power equipment clusters in the target regional power grid to the overall frequency fluctuation of the target regional power grid is different, so that a correlation value can be obtained through correlation analysis, and the power equipment clusters with high correlation value in the target regional power grid are used as target power equipment clusters causing the frequency fluctuation.
The correlation value may be determined using a pearson correlation coefficient, which is defined as follows:
wherein X is i ,Y i Respectively two groups of data to be compared,the average of the two sets of data is given, n is the total data, and r is the pearson correlation coefficient.
According to the method and the device, the target power equipment cluster causing frequency variation is determined from the regional power grid according to the correlation value, and the efficiency of determining the target power equipment cluster is improved.
In one embodiment, as shown in fig. 5, obtaining control instruction information generated by a scheduling mechanism in scheduling a target power device cluster includes:
step 51, determining a scheduling mechanism corresponding to the target power equipment cluster;
step 52, obtaining a control instruction sending record of the dispatching mechanism from a preset database;
Step 53, extracting, from the control instruction transmission record, a control instruction transmitted by the scheduling mechanism to the target power equipment cluster as control instruction information.
Specifically, the scheduling mechanism controlling the target power equipment cluster typically records and saves the transmission condition of the control instruction, so that the control instruction transmitted by the scheduling mechanism to the target power equipment cluster can be obtained as control instruction information through the control instruction transmission record.
The server in the embodiment obtains the control instruction information through the control instruction sending record extraction of the scheduling mechanism, and ensures the accuracy of the control instruction information.
