Description

Technical Field

[0001] The present invention relates to the field of intelligent operation and maintenance of power system substations, and in particular to a method for setting a main transformer heavy overload function interface of a novel centralized control system. Background Art

[0002] With the increase of social power load, the pace of power grid construction is gradually accelerating. The operation of a large number of newly built substations has expanded the scale of the power grid, causing a rapid increase in the workload of power grid operation. The existing human resources and operation management model have gradually failed to meet the needs of power grid development. It is urgent to improve the quality of substation monitoring and operation. In recent years, the development of network communication technology and the improvement of primary / secondary equipment have provided reliable theoretical support for exploring new technical models for the operation and maintenance of centralized control station systems.

[0003] For the new centralized control station system, main transformer overload is a common fault in station operation. Considering the complex internal structure of the main transformer, it is difficult to directly measure the hot spot temperature. In order to avoid problems caused by abnormal temperature, the monitoring and operation of the main transformer overload is extremely critical. In the prior art, the monitoring and operation system for the main transformer overload in the centralized control station system is not intelligent enough, and the monitoring and operation function still needs to be further improved. Therefore, it is necessary to specify a method for setting the main transformer overload function interface of a new centralized control system to solve the above problems. Summary of the invention

[0004] Purpose of the invention: The purpose of the invention is to provide a method for setting the main transformer overload function interface of a new centralized control system.

[0005] Technical solution: The present invention optimizes the functional application requirements of the new generation centralized control station equipment monitoring system regarding main transformer overload, and provides main transformer monitoring function, main transformer overload information function, main transformer overload intelligent alarm function, main transformer information intelligent patrol function, main transformer overload auxiliary decision-making function, and main transformer overload intelligent reporting function in the functional interface. The application functions are distributed in safety zone I and safety zone IV.

[0006] Furthermore, the safety zone I is used to realize the main transformer monitoring function, the main transformer heavy overload information function, the main transformer heavy overload intelligent alarm function, the main transformer information intelligent patrol function, the main transformer overload auxiliary decision function and the main transformer heavy overload intelligent reporting function.

[0007] Furthermore, the safety IV zone simultaneously realizes the main transformer information intelligent patrol function, the main transformer overload auxiliary decision-making function and the main transformer heavy overload intelligent reporting function.

[0008] Furthermore, the main transformer monitoring function has two modes: sorting by all substations and classifying by substation voltage level. At the same time, based on the original specifications, it adds sorting by all substations and eye-catching reminder of oil temperature exceeding the limit, and supplements the load rate calculation method.

[0009] Furthermore, the main transformer overload information includes substation name, equipment name, telemetry, limit value, status, over-limit start time, over-limit duration and load rate, and uses different colors to remind monitoring personnel to pay special attention.

[0010] Furthermore, in the main transformer heavy overload intelligent alarm function, the main transformer load rate alarm limit is divided into limit 1, limit 2, and limit 3, which are 0.8, 0.9, and 1.0 respectively. When the main transformer load rate reaches the alarm limit, the main transformer heavy overload intelligent alarm function will trigger the corresponding alarm information in the real-time alarm window, where the main transformer load rate calculation formula is: main transformer load rate = main transformer apparent power / main transformer rated capacity × 100%.

[0011] Furthermore, the main transformer information intelligent patrol function supports manual selection of patrol objects; supports selection of multiple patrol objects at one time; supports automatic start of main transformer information intelligent patrol when a main transformer is heavily overloaded; can generate patrol reports and support query, statistics and export functions.

[0012] Furthermore, the main transformer overload auxiliary decision function interface is fixed in a templated form, and when the main transformer is overloaded, the system automatically pops up a main transformer overload auxiliary decision window.

[0013] Furthermore, the main transformer overload intelligent reporting function has a report template management function and a report data display function.

[0014] Furthermore, the main transformer information intelligent patrol function includes telemetry over-limit, suppression information, blocking information, sign setting status, non-reset information and abnormal light sign.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: it meets all the current requirements of main transformer overload monitoring and operation and maintenance of the new centralized control system; based on the functional application requirements of the new generation of centralized control station equipment monitoring system for main transformer overload, it reasonably allocates different functional areas, and further optimizes the main transformer overload function interface of the centralized control system. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is an overview of the functional application structure relationship of the present invention. DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1As shown, the present invention optimizes the functional application requirements of the new generation centralized control station equipment monitoring system regarding main transformer overload, and provides a main transformer monitoring function, a main transformer overload information function, a main transformer overload intelligent alarm function, a main transformer information intelligent patrol function, a main transformer overload auxiliary decision function, and a main transformer overload intelligent report function in the function interface. The application functions are distributed in safety zone I and safety zone IV.

[0019] Safety zone I realizes main transformer monitoring function, main transformer heavy overload information function, main transformer heavy overload intelligent alarm function, main transformer information intelligent patrol function, main transformer overload auxiliary decision function, and main transformer heavy overload intelligent report application function.

[0020] Safety Zone IV simultaneously realizes the main transformer information intelligent patrol function, main transformer overload auxiliary decision-making function, and main transformer heavy overload intelligent report application function.

[0021] The main transformer monitoring function has two modes: classification by all substations and classification by substation voltage level. At the same time, based on the original specification, the sorting by all substations and the eye-catching reminder of oil temperature exceeding the limit are added, and the load rate calculation method is supplemented. Among them, the important telemetry data of the transformer include active power, reactive power, current, temperature, and load rate. Click the right mouse button to call up the historical curve. The main transformer temperature has oil temperature 1, oil temperature 2 and winding temperature, which should be displayed separately. The system calculates the transformer load rate based on the real-time data of each transformer and automatically determines its load condition. The information of the heavily overloaded main transformer is highlighted in color, where yellow represents the main transformer heavy load and red represents the main transformer overload. When the main transformer oil temperature reaches the alarm limit, the oil temperature data turns red and a white border is added to make it eye-catching. The main transformer load rate calculation formula is: main transformer load rate = main transformer apparent power / main transformer rated capacity × 100%. Substations are arranged in a fixed order. Click the Load Rate Sort (Transformer) button in the upper right corner to sort and display them from large to small according to the highest load rate of the main transformer; click the Load Rate Sort (Substation) button in the upper right corner to sort and display them from large to small according to the substation with the highest load rate of the main transformer; click the heavy overload monitoring bar in the upper right corner to enter the main transformer heavy overload monitoring interface; double-click the substation name to jump to the corresponding substation overview; double-click the transformer name to jump to the corresponding transformer bay sub-diagram.

[0022] Select the "Heavy Overload Pop-up Window" column in the main transformer heavy overload monitoring interface or right-click the alarm message in the real-time alarm window to display the main transformer heavy overload information. The main transformer heavy overload information interface contains substation name, equipment name, telemetry, limit, status, over-limit start time, over-limit duration, and load rate information, and uses different colors to remind monitoring personnel to pay attention. The heavy load active value, load rate and status are yellow, and the overload active value, load rate and status are red. When the oil temperature reaches the alarm limit, the font turns red with a white border. Click the load rate to sort by load rate from high to low.

[0023] The main transformer load rate alarm limit should be at least divided into three levels: limit 1, limit 2, and limit 3, which are 0.8, 0.9, and 1.0 respectively. When the main transformer load rate reaches the alarm limit, the main transformer heavy overload intelligent alarm function will trigger the corresponding alarm information in the real-time alarm window (such as xx main transformer real-time load rate 0.81, exceeding upper limit 1, limit 0.8; xx main transformer real-time load rate 0.91, exceeding upper limit 2, limit 0.9; xx main transformer real-time load rate 1.01, exceeding upper limit 3, limit 1.0), and voice broadcast. This function takes hysteresis alarm measures to avoid the main transformer load rate fluctuating near the limit, causing frequent alarms at the same limit. Set the reset value to be 0.05 less than the alarm limit, the limit 1 alarm value is 0.8, the reset value is 0.75, the limit 2 alarm value is 0.9, the reset value is 0.85, the limit 3 alarm value is 1.0, and the reset value is 0.95. The improvement is that after the same limit value alarm is triggered, if it is not restored, the limit value alarm will no longer be triggered, and the alarms between different limit values ​​are independent of each other.

[0024] The intelligent inspection function of main transformer information supports manual selection of inspection objects. The inspection object list includes all main transformers of all substations under its jurisdiction; it supports selecting multiple inspection objects at one time. Click "One-click Inspection" to complete the inspection of the selected object, and generate a list of inspection results below. Each object generates a report. Click "Inspection Report" in the inspection list to view detailed information; it supports automatic startup of main transformer information intelligent inspection when a main transformer is heavily overloaded, and inspects the main transformer. If the xx main transformer is heavily overloaded multiple times on the same day, the main transformer intelligent inspection function will only be started when it is heavily loaded and overloaded for the first time on the same day; it can generate inspection reports and support query, statistics and export functions.

[0025] Intelligent inspection function of main transformer information, including:

[0026] Telemetry over-limit, which displays the over-limit telemetry values ​​of the main transformer interval in a list format, in the format of telemetry name + current value / limit value;

[0027] The data is not refreshed, and the telemetry data of the main transformer interval that is not refreshed is displayed in a list format, with the format of telemetry name + current non-refreshed value;

[0028] Suppression information, which displays information about suppression of the main transformer bay in a list format, in the format of suppressed information;

[0029] Blocking information, which displays the information that the main transformer interval is blocked in a list format, and the format is blocked information;

[0030] The card placement situation displays the card type and content when there is a card placed in the main variable interval. The format is card type + content;

[0031] Unrestored information, which displays the unrestored information existing in the main transformer interval in a list format, in the format of unrestored information;

[0032] Abnormal light sign, which displays the abnormal light sign information existing in the main transformer interval in a list format, and the format is abnormal light sign information;

[0033] Alarm information within a week, which displays the alarm information of the main transformer in the past week in a list format, and counts the number of times; (for example, if the inspection time is 2023.12.12 10:00, the alarm information statistical period is 2023.12.05 10:00).

[0034] The main transformer overload auxiliary decision-making function interface is fixed in a templated form. The interface includes phenomena, signal interpretation, common causes, consequences, monitoring and operation and maintenance personnel handling principles, and operation and maintenance personnel handling principles; the content displayed on this interface is fixed in a template form. When the main transformer is overloaded, the system can automatically pop up the main transformer overload auxiliary decision-making window. The window display content is similar to the main transformer overload auxiliary decision-making interface, where the phenomenon is the specific information of the current overloaded main transformer; when a single main transformer is overloaded multiple times or multiple main transformers are overloaded multiple times, the window will automatically pop up once for each overload.

[0035] The main transformer heavy overload intelligent report interface contains three sub-columns: heavy overload daily report, heavy overload daily report, heavy overload weekly report, and monthly report. You can enter the corresponding report interface by clicking. In the upper left corner of the report interface, select the query start and end time, select the heavy load criterion and overload criterion, click query, and the report can be generated. The main transformer heavy overload intelligent report has report template management functions, including template creation, content style editing, data content editing, data filtering condition editing, etc.; it also has report data display functions, including: support for permission ranges configured by template; display of data readable by the currently logged in user; support for data reading and display according to the style defined by the template; support for data filtering and display according to the configured query filtering conditions; the report content can be directly exported as a spreadsheet or text file, and printing is supported.
