Abstract
Description
Technical Field
[0001] The present invention relates to a phase selection opening and closing adjustment method, and in particular to an intelligent method for data management, waveform analysis and opening and closing time constant setting of a phase selection opening and closing device. Background Art
[0002] At present, for conventional converter stations, the converter transformers, main transformers, and AC filter circuit breakers in the station all use phase-selective opening and closing devices to accurately control their opening and closing phases. Due to power adjustment, system fluctuations and other reasons, the AC filter circuit breaker is frequently opened and closed. At the same time, under the influence of factors such as ambient temperature, circuit breaker intermittent time, circuit breaker oil pressure, and air pressure, the phase-selective opening and closing device needs to perform a large amount of tedious waveform analysis and opening and closing time constant adjustment work, and a large amount of analysis data needs to be stored. The currently used methods of manual analysis, manual adjustment, and manual storage and archiving result in uneven analysis results with large differences, and cannot achieve good results. At present, no technical means similar to the present invention have been found. Summary of the Invention
[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide an intelligent method for data management, waveform analysis and setting of closing and opening time values of a collectively selected phase opening and closing device.
[0004] In order to achieve the above object, the technical solution adopted by the present invention is: A method for intelligent data management, waveform analysis, and opening and closing time constant value adjustment of a phase-selective opening and closing device, wherein the phase-selective opening and closing device includes a data management platform, automatic waveform analysis software, and constant value adjustment logic; the method for intelligent data management, waveform analysis, and opening and closing time constant value adjustment of the phase-selective opening and closing device includes the following steps: Step 1: Collect data for one cycle and export data reports through the data management platform and waveform automatic analysis software; Step 2: Adjust the opening and closing time setting; If the circuit breaker opening and closing time exceeds the opening and closing time setting value ±1ms for less than 3 times in one cycle, there is no need to adjust the opening and closing time setting value; If the circuit breaker opening and closing time exceeds the time setting range of ±1ms for 3 or more times in one cycle, the opening and closing time setting adjustment logic will be entered: If the number of circuit breaker opening and closing times exceeding the opening and closing time setting value of ±1ms is greater than or equal to the number of times not exceeding the setting value, the opening and closing time setting value is adjusted to the average of the actual opening and closing times of all circuit breakers exceeding the opening and closing time setting value of ±1ms. The opening and closing time setting value t x As shown in Formula 1: Formula 1 Where n is the total number of circuit breaker opening and closing times exceeding the opening and closing time setting value ±1ms; If the number of opening and closing times of the circuit breaker that exceeds the opening and closing time setting value of ±1ms is less than the number that does not exceed the setting value, the opening and closing time setting value is adjusted to the average of the actual opening and closing times of all circuit breakers exceeding the time setting value of ±1ms minus half of the original opening and closing time setting value, plus the original opening and closing time setting value. The opening and closing time setting value t x As shown in Formula 2: Formula 2 Where n is the total number of circuit breaker opening and closing times exceeding the opening and closing time setting value ±1ms, t y It is the original opening and closing time setting value; Step 3: Push the opening and closing time setting value adjusted in step 2 to the data management platform in the form of a data packet to form a time setting value adjustment report within a cycle. After manual confirmation, a setting value list is generated and enters the approval process. After approval, it is implanted into the phase selection opening and closing device to take effect.
[0005] Furthermore, the data management platform has the functions of managing and monitoring the real-time operating status of the circuit breaker, retrieving waveform files and viewing key opening and closing data within a cycle.
[0006] Furthermore, the waveform automatic analysis software has the function of extracting switching value and analog value data in the waveform and exporting data reports.
[0007] Furthermore, the circuit breakers include a converter transformer circuit breaker, a main transformer circuit breaker and an AC filter circuit breaker.
[0008] Furthermore, the one cycle is one month.
[0009] Furthermore, the data in the data report exported by the waveform automatic analysis software includes the recording name, name, actual action time, set action time, time difference, actual action angle, set action angle, angle difference, maximum inrush current and tripping overvoltage.
[0010] Furthermore, a group of the converter transformer circuit breakers, the main transformer circuit breaker and the AC filter circuit breaker are signal-connected to the data management platform via a switch.
[0011] Furthermore, the data management platform is signal-connected to multiple groups of converter transformer circuit breakers, main transformer circuit breakers, and AC filter circuit breakers through multiple switches.
[0012] Furthermore, the switch is further connected to the data management platform signal through the data platform host.
[0013] Furthermore, the data platform host is further connected to the data management platform signal through the data platform workstation.
[0014] The beneficial effects of the present invention are as follows: based on an intelligent data management platform, the present invention forms a set of data management, waveform analysis, and fixed value adjustment methods from waveform to data, from cumbersome to concise, and from uneven to unified. By importing the waveform of the phase-selective opening and closing device into the waveform automatic analysis software, a key data report is generated with one click, and then a trend analysis curve is generated for all the key opening and closing data of the same circuit breaker within a cycle, and a phase-selective opening and closing fixed value adjustment suggestion is generated through intelligent logical judgment. The present invention provides a solution for centralized networking of multiple phase-selective opening and closing devices for data management, waveform analysis, and fixed value adjustment through digital means, which reduces labor costs and human errors, standardizes the method of fixed value calculation and adjustment, simplifies the daily operation and maintenance of the phase-selective opening and closing device, reduces labor costs, eliminates human errors, and improves the management efficiency of the phase-selective opening and closing device. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 is a schematic diagram of a data management platform according to an embodiment of the present invention; Figure 2 It is a logic diagram of the fixed value adjustment of the present invention. DETAILED DESCRIPTION
[0016] The present invention will be further described in detail below with reference to the embodiments. The present invention mainly comprises three parts: a data management platform, automatic waveform analysis software, and fixed value adjustment logic.
[0017] Data management platform: such as Figure 1 As shown, based on the tree structure, the converter transformer circuit breaker, main transformer circuit breaker, and AC filter circuit breaker are classified into different categories, which makes it easy to view the real-time operating status of each circuit breaker, retrieve waveform files, and view key opening and closing data within a cycle.
[0018] Waveform automatic analysis software: extract the switch quantity and analog quantity data in the waveform and export the data report, as shown in Table 1. Table 1 Data report
[0019] Fixed value adjustment logic: see attached Figure 2 As shown in the figure, the three-phase opening and closing time of the circuit breaker in a cycle (usually one month) in the waveform report is used as input, and after calculation, suggestions for adjusting the fixed values of the three-phase opening and closing time are given. After manual confirmation and execution of the fixed value list approval process, the phase selection opening and closing device is implanted.
[0020] If the circuit breaker opening and closing time exceeds the time setting value ±1ms range less than 3 times in a cycle, it is considered that the setting value does not need to be adjusted; if the circuit breaker opening and closing time exceeds the time setting value ±1ms range 3 or more times in a cycle, the setting value adjustment logic is entered.
[0021] Detailed description of the set value adjustment logic: If the number of opening and closing times exceeding the time set value ±1ms is greater than or equal to the number not exceeded, the new time set value is adjusted to the average of all actual opening and closing times exceeding the time set value ±1ms.
[0022] Formula 1 Where n is the total number of opening and closing times exceeding the time setting value ±1ms; If the number of opening and closing times exceeding the time setting value by ±1ms is less than the number within the limit, the time setting value shall be adjusted to the average of all actual opening and closing times exceeding the time setting value by ±1ms minus half of the original time setting value, plus the original time setting value.
[0023] Formula 2 Where n is the total number of opening and closing times exceeding the time setting value ±1ms, t y The original time value.
[0024] The new time constant is calculated by the above formula and pushed to the data management platform in the form of a data packet to form a constant adjustment report within a cycle. After manual confirmation, a constant order is generated and enters the approval process. After approval, the implanted device takes effect.
[0025] In actual engineering applications, due to the location, altitude and climate of the converter station, the opening and closing times of the AC filter circuit breaker, which is frequently operated, have large deviations. The above-mentioned fixed value adjustment method can ensure that when the AC filter is switched on and off due to reactive power requirements, the actual opening and closing times of the circuit breaker can be controlled within the ideal range.
[0026] The above content is only used to illustrate the technical solution of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention made by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
