Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for generating the regional power grid control report can be applied to the application environment shown in fig. 1. Among them, the scheduling terminal 11 communicates with the server 12 through a network. The server 12 acquires the real-time operating frequency of the regional power grid from the dispatching terminal 11; if the server 12 detects that the variation range of the real-time operating frequency does not belong to the preset variation range, determining a target power equipment cluster causing frequency variation from the regional power grid; the server 12 obtains control instruction information generated by a scheduling mechanism for scheduling a 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; and 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 workbench, a personal computer, a notebook computer, a smart phone, a tablet computer, etc. which are equipped with or communicatively connected to the power dispatch system, and the server 12 may be implemented by an independent 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, which is described by taking the method as an example applied to the server 12 in fig. 1, and includes the following steps:
and step 21, acquiring the real-time operation frequency of the regional power grid.
The power grid can be divided according to the geographic position to obtain a plurality of regional power grids; each regional power grid is composed of a single power device or a power device cluster obtained by integrating a plurality of power devices.
Specifically, the server is in communication connection with the dispatching terminal and receives the real-time running frequency of the regional power grid controlled by the dispatching terminal, wherein the real-time running frequency is acquired by the dispatching terminal; the scheduling terminal can update the operation frequency to the server in real time or periodically update the operation frequency to the server.
Besides acquiring the real-time frequency of the regional power grid, the scheduling terminal can also acquire environmental information of each power device or power device cluster in the regional power grid, such as temperature, humidity, pressure values and the like.
In the step, the server is connected with the dispatching terminal, the real-time operating frequency of the regional power grid acquired by the dispatching terminal can be acquired, the acquisition efficiency of the frequency data of the regional power grid can be improved by uniformly acquiring through the dispatching terminal, and the acquisition efficiency of the data required by the report generation is improved.
And step 22, if the variation range of the real-time operation frequency is detected not to belong to the preset variation range, determining a target power equipment cluster causing the frequency variation from the regional power grid.
The preset variation range is a fluctuation limit value set for the real-time operation frequency of the regional power grid, and when the variation range of the operation frequency exceeds the variation range of the frequency, the condition that the frequency of the regional power grid is abnormal is indicated; for example, if the preset variation range is within plus or minus 20, and the server detects that the variation range of the real-time operating frequency is plus 30, it can be determined that the variation range of the real-time operating frequency is beyond the preset variation range, i.e. does not belong to the preset variation range. The preset variation range may be directly set as the frequency, and may also be set as an index related to the real-time frequency of the regional power grid, such as an average frequency value, a median frequency value, a variance, and the like within a certain period of time.
The real-time operation frequency change detection can be specifically carried out through the following aspects: 1) whether the frequency is suddenly changed is judged according to whether the difference value of the frequency sampling points in the continuous time (for example, set to be 2 seconds) is larger than a fixed value; 2) judging whether the frequency deviation is larger than a specified value or not according to the fact that whether the difference between the actual frequency value and the rated value is larger than the specified value or not; 3) the frequency is in high frequency or low frequency for a certain time, and whether the time of the frequency which is continuously larger than the high frequency fixed value or smaller than the low frequency fixed value is larger than a fixed value or not is judged according to the judgment; 4) the frequency continuously fluctuates between high frequency and low frequency, and whether the time period and the fluctuation amplitude value of the frequency are respectively larger than a fixed value is judged according to the condition.
The target power equipment cluster refers to the power equipment or the power equipment cluster which is determined by the server from the regional power grid and causes the frequency change.
For example, 3 power equipment clusters A, B, C are shared in a local grid, the index of the overall frequency variation range of the local grid is 10, the index of the frequency variation range of the power equipment cluster a is 5 after detection by the server, and the index of the frequency variation of the power equipment cluster B, C is 1, then the server may determine the power equipment cluster a as a target power equipment cluster which causes frequency variation in the local grid.
Further, if the server can acquire the real-time frequency of each electrical device in the electrical device cluster a from the scheduling terminal, the server can further identify the target electrical device causing the frequency variation from the electrical device cluster a. The determination of the target power equipment cluster or the target power equipment may be one or more, and may specifically be determined according to a specific influence of the target power equipment cluster or the target power equipment on the frequency variation.
In this step, by detecting the abnormal frequency change, the target power equipment cluster causing the frequency change is identified from the regional power grid, the range of the abnormal power equipment can be quickly 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, acquiring control instruction information generated by the dispatching mechanism in dispatching the target power equipment cluster.
The control command information is data information generated when the scheduling mechanism schedules the electric power equipment or the electric power equipment cluster, and all information related to the control command can be known from the control command information, such as specific control command content, sending time of the control command, execution condition of the control command returned by a sending engine, the electric power equipment or the electric power equipment cluster, and the like; the control instruction information corresponds to a log file when the scheduling mechanism performs scheduling, and the server can analyze the cause of the abnormality of the target power equipment cluster causing the frequency variation through the control instruction information.
The control instruction information also includes overall operation state information of the regional power grid, such as: analyzing the operation state of a regional power grid, including a load level, the frequency of the regional power grid, the change condition of total regional active power and the like; secondly, analyzing the direct current outgoing state, and comparing the direct current outgoing call wire power with the system frequency condition; analyzing the automatic gain control state, including whether the automatic gain control has an abnormal alarm or not and which electric equipment or electric equipment clusters are put into the automatic gain control function; fourthly, analyzing a PLC (Programmable Logic Controller) control instruction, and judging whether the PLC automatic gain control instruction of the power plant is reasonable or not; and fifthly, analyzing the active power regulation of the power plant, and judging whether the output of the power plant fluctuates in the boosting frequency under the automatic gain control.
Specifically, the server firstly determines a specific scheduling mechanism or scheduling terminal corresponding to the target power equipment cluster; and acquiring the control instruction information generated and stored when the scheduling mechanism or the scheduling terminal carries out scheduling operation from the scheduling mechanism or the scheduling terminal. If the server acquires the direct control instruction information, the server can generate the corresponding control instruction information by summarizing the logs, the instruction sending records and the like of the scheduling mechanism.
In the step, the control instruction information generated by scheduling the target power equipment cluster is acquired, so that the operating 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 regional power grid abnormal frequency are improved.
And 24, verifying the control instruction issued by the scheduling mechanism to the target power equipment cluster according to the control instruction information.
Specifically, the server can obtain a control instruction issued by the scheduling mechanism to the target power equipment cluster according to the control instruction information; the instruction issuing logic of the scheduling mechanism can be verified according to the control instruction, and the result of the target power equipment cluster executing the control instruction can also be verified, so that the reason of causing the real-time operation frequency abnormity is judged according to the verification result.
Verifying the control instruction includes: firstly, determining which electric equipment or electric equipment cluster is put into an automatic gain control mode of a scheduling mechanism; secondly, reading an automatic gain control instruction received by the electric power equipment or the electric power equipment cluster during the frequency abnormity; thirdly, determining whether the output instruction is an increased output instruction or a decreased output instruction by comparing the actual output of the power equipment or the power equipment cluster aiming at each automatic gain control instruction; and fourthly, determining the correctness of the logic aspect of the automatic gain control instruction of the dispatching mechanism by judging whether the electric power equipment or the electric power equipment cluster receives the output reducing instruction at the high frequency or not and whether the electric power equipment or the electric power equipment cluster receives the output increasing instruction at the low frequency or not.
For example, after the server verifies the control instruction, it finds that the target power equipment cluster normally executes the control instruction, and the execution result conforms to the expectation of the control instruction, so that the abnormality of the target power equipment cluster can be eliminated; verifying the trigger control instruction of the scheduling mechanism, wherein the error exists when the scheduling mechanism performs data calculation, so that the prediction frequency of the target power equipment cluster in the next time period is judged by mistake, and the wrong control instruction is issued; the server checks the control instruction based on the control instruction 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 abnormal generation object and a specific reason can be identified quickly, and the generation efficiency of the regional power grid control report and the timeliness of monitoring the regional power grid abnormal frequency are improved.
And 25, generating a regional power grid control report corresponding to the dispatching mechanism according to the checking result.
Specifically, the server can output the verification result in a report form; the server firstly determines an object with abnormal generation and a specific abnormal reason according to a check result, acquires corresponding data from the object with abnormal generation, and correspondingly fills the corresponding data into a preset regional power grid control report template.
The server may employ a java (one-door object-oriented programming language) based poi-tl (Word template engine); the POI-tl is a Word template engine based on Apache POIs, and can generate a Word document according to a specified format, and the Word content generally comprises the following aspects:
1) the event overview is used for showing the time of the regional power grid frequency abnormity, the regional control error (ACE), the maximum frequency, the minimum frequency, a regional power grid frequency graph and the like; 2) the system load and outgoing change conditions are used for displaying the output change of the high-capacity power plant and the active-frequency comparison conditions of the whole network and outgoing lines; 3) event passes for showing the target power equipment cluster and/or the active frequency comparison condition and Automatic Gain Control (AGC) instruction execution condition of the target power equipment; 4) and an Automatic Gain Control (AGC) operation condition for showing the condition of Automatic Gain Control (AGC) failure during the frequency abnormal period.
According to the method, the server generates the regional power grid control report corresponding to the dispatching mechanism according to the checking result, data can be summarized and the corresponding report can be automatically generated, manual data arrangement and arrangement are not needed, and the generation efficiency of the regional power grid control report is improved.
In the method for generating a regional power grid control report, the method includes: acquiring the real-time operating frequency of a regional power grid; if the variation range of the real-time operation frequency is detected not to belong to the preset variation range, determining a target power equipment cluster causing frequency variation from the regional power grid; acquiring control instruction information generated by a scheduling mechanism for scheduling a target power equipment cluster; according to the control instruction information, verifying a control instruction issued by a scheduling mechanism to the target power equipment cluster; and generating a regional power grid control report corresponding to the dispatching mechanism according to the checking result. The method comprises the steps of monitoring the running frequency of the power grid in real time, identifying a target power equipment cluster generating abnormity after abnormity is monitored, checking an instruction sent to the target power equipment cluster by a relevant scheduling mechanism, and judging whether the logic of the instruction issued by the scheduling mechanism is correct or not and generating a corresponding control report; data do not need to be collected, analyzed and confirmed manually, abnormity can be identified and a report can be generated at the first time, and the generation efficiency of a regional power grid control report and the timeliness of monitoring abnormal frequency of a regional power grid are greatly improved.
In one embodiment, as shown in fig. 3, if it is detected that the variation range of the real-time operating frequency does not belong to the preset variation range, the method includes:
and step 32, comparing the plurality of 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 operation frequency exceeds the preset frequency variation values, and taking the regional power grid as a target regional power grid.
The change degree of the whole regional power grid in different aspects of frequency can be reflected by a plurality of frequency change indexes obtained through feature extraction; 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 the regional power grid which has the frequency abnormality problem and is determined after the real-time operation frequency monitoring is carried out on the plurality of regional power grids, and the function of quick positioning is achieved.
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 variation amplitude, frequency variation increase and decrease amplitude and the like to obtain a plurality of frequency variation indexes; and acquiring a preset frequency variation value set from a preset database, comparing each frequency variation index with a corresponding preset frequency variation value in the preset frequency variation value set, and determining a target regional power grid according to a comparison result.
In the embodiment, the frequency variation index is compared with a preset frequency variation value, whether the variation range of the real-time operating 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 target regional power grid can be rapidly determined by screening in a regional mode, and the data range is reduced; the operation state and trend of the whole regional power grid can be better reflected through the index.
In one embodiment, as shown in fig. 4, the determining a target power device cluster causing a frequency variation from a regional power grid includes:
and 43, taking the power equipment cluster with the correlation value exceeding the preset threshold value as a target power equipment cluster causing frequency change in the regional power grid.
Specifically, the server may directly obtain the power device cluster existing in the target area grid according to the pre-stored area grid information, or may send a request to a console of the target area grid to obtain power device cluster information included in the request.
The frequency variation between the power equipment cluster and the target regional power grid is correlated, but the contribution of different power equipment clusters in the target regional power grid to the overall frequency variation of the target regional power grid is different, so that a correlation value can be obtained through correlation analysis, and a power equipment cluster with a high correlation value in the target regional power grid is taken as a target power equipment cluster causing the frequency variation.
The correlation value may be determined using a pearson correlation coefficient, which is defined as follows:
wherein, Xi,YiTwo sets of data to be compared are provided,
the average values of the two groups of data are respectively, n is the total amount of the data, and r is the Pearson correlation coefficient.
According to the embodiment, the target power equipment cluster causing the frequency change 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 an embodiment, as shown in fig. 5, the obtaining of the control instruction information generated by the scheduling mechanism by scheduling the target power device cluster includes:
and step 53, extracting the control command sent to the target power equipment cluster by the dispatching mechanism from the control command sending record as control command information.
Specifically, the scheduling mechanism of the control target electrical equipment cluster usually records and stores the condition of sending the control instruction, so the control instruction sent to the target electrical equipment cluster by the scheduling mechanism can be obtained as the control instruction information through the control instruction sending record.
The server obtains the control instruction information by sending, recording and extracting the control instruction of the scheduling mechanism, and the accuracy of the control instruction information is ensured.
In one embodiment, the control instruction information carries a time identifier; according to the control instruction information, the control instruction issued by the scheduling mechanism to the target power equipment cluster is verified, and the method comprises the following steps: according to the time identification, the control instruction information corresponds to the real-time running frequency; and correspondingly matching an expected control result corresponding to the control instruction information with an actual change result of the real-time operating frequency, and verifying the control instruction according to the matching result.
Specifically, the server corresponds the control instruction information with the real-time running frequency according to the time identifier, namely, the influence of the control instruction on the real-time running frequency is judged in the same time dimension; meanwhile, the control instruction is used for controlling the target power equipment cluster, so that the control instruction information also contains an expected control result; the expected control result is matched with the actual change result of the operating frequency, whether the control instruction is successfully executed or not can be judged, and therefore the control instruction is verified.
