[0085] It is composed of Arabic numerals, including project, unit and specific standard coding information;

[0086] It can be: the first digit in the index standard code determines which phase of the capital construction or renovation project the unit belongs to, the second digit determines which unit the report index belongs to, and the last four or more digits indicate the specific standard code;

[0087] For example: There are four units in a power plant, of which units 3 and 4 belong to the second phase project, and the index is 240003, where 2 represents the second phase project, 4 represents unit 4, and 0003 is the specific standard code.

[0089] The calculation formulas for the system and equipment performance indicators are used to calculate indicators such as computer group and equipment performance, efficiency, output, etc., such as shaft power, output power, heat rate, etc.;

[0090] The calculation formula of the heat index is used to calculate the heat energy loss, heat efficiency and heat balance of the computer group, such as high heating efficiency, steam turbine heat consumption, condenser thermal efficiency, etc.

[0091] The flow and pressure correction calculation formula is used to correct the calculation of flow and pressure data output by the field pipeline steam, water flow, and steam pressure measurement unit at different temperatures and pressures, such as main steam flow, extraction steam flow, feed water flow, flue gas flow, etc.;

[0092] The electric energy metering index calculation formula is used to calculate indicators such as power generation, unit consumption, and power supply, for example: power generation of unit 1, unit consumption of coal mill, power consumption of induced draft fan, etc.;

[0101] The fuel metering calculation formula is used to calculate indicators such as the amount of coal entering the port, the amount of coal measured on the track, the amount of lime slurry, the amount of coal in the coal yard and the amount of coal entering the furnace.

[0102] As well as the cumulative indicator calculation formulas, class indicator calculation formulas, daily indicator calculation formulas, class indicator table code conversion formulas, daily indicator table code conversion formulas, daily indicator class indicator conversion formulas, monthly indicator daily indicator conversion formulas, quarterly indicator monthly indicator conversion formulas, annual indicator monthly indicator conversion formulas and reference indicator calculation formulas which are respectively used to realize the cumulative indicator calculation, class indicator calculation, daily indicator calculation, class indicator table code conversion formulas, daily indicator table code conversion formulas, daily indicator class indicator conversion formulas, monthly indicator daily indicator conversion formulas, quarterly indicator monthly indicator conversion formulas, annual indicator monthly indicator conversion formulas and reference indicator calculation formulas.

[0103] In the embodiment of the present application, indicator conversion is defined, and the indicator conversion formula uses the corresponding sub-level indicator as the "base" for accumulation or averaging.

[0104] For example, for an indicator with the standard code of 240001, the calculation formula for the shift indicator is: Get shift indicator data ("field data, @DATETIME, @SHIFTSYSTEM, @SHIFT, AVG"), the calculation formula for the daily indicator is: Get daily indicator data ("field data, @DATETIME, @DATETIME, AVG"), the calculation formula for the monthly indicator is: Convert monthly indicator to daily indicator ("240001, AVG"), and the calculation formula for the annual indicator is: Convert annual indicator to monthly indicator ("240001, AVG")

[0105] The reference indicator formula can only be referenced at the same level, for example: daily indicator reference indicator: daily indicator ("240001") / daily indicator ("240168")*M.

[0106] The system configuration calculation module obtains the real-time data of the production and operation environment of the thermal power plant through the unified interface platform of the SIS system, performs configuration calculation on the real-time data of the production and operation environment measurement points of the thermal power plant and various index data, obtains the real-time data and index data of various table measurement points with standard coding, and stores them in the Oracle database;

[0107] The standard coding of the real-time data of the measuring point includes the standard coding of the unique real-time data of the measuring point after the real-time data processing of the SIS system unified interface platform, so as to standardize the unique identification of the data participating in the index calculation; it is composed of Arabic numerals and letters, and refers to a part of the KKS (Kraftwerk-Kennzeichensystem, power plant identification system) coding, including the capital construction or transformation period, unit, system, subsystem, equipment, parameter type, and parameter specific standard coding;

[0108] It can be: the first digit of the standard code of the real-time data of the measuring point determines which phase of infrastructure or renovation it belongs to, the second and third digits determine which unit it belongs to, the fourth and fifth digits determine which system it belongs to, the sixth, seventh and eighth digits determine which subsystem it belongs to, the ninth, tenth, eleventh and twelfth digits determine which equipment it belongs to, the thirteenth and fourteenth digits determine which type of parameter it belongs to, and the remaining four digits are the standard code of the real-time data of the measuring point itself;

[0109] For example: Phase II infrastructure construction area, Phase II infrastructure construction #3, #4 units, boiler system number is 02, coal mill belongs to the combustion system, combustion system number is 003, coal mill equipment number is 0124, temperature parameter standard code is TT, parameter arrangement number is 322, data 230020030124TT0322, is the front shaft bearing temperature of the boiler coal mill of Phase II unit 3;

[0110] The system configuration calculation module includes various drag-and-drop application modules that encapsulate various mathematical calculation functions and chart query and value tools;

[0111] The drag-and-drop application module is used to configure calculation formulas and form new calculation formulas to complete different calculation tasks;

[0112] The chart query value acquisition tool uses a linear algorithm and a least squares algorithm to gradually approach the curve value acquisition method, and obtains reference standard values ​​for participating index calculations that reflect the actual performance and energy consumption of the unit system or equipment from the unit commissioning or performance test curve or data table;

[0113] The system configuration calculation module is used for configuring the calculation formula. After forming a new calculation formula, a standard code is assigned to the calculation formula. The standard code of the calculation formula is used to uniquely identify the calculation formula for use when querying and calling the calculation formula.

[0114] For example, the standard code of the standard coal consumption index calculation formula is 200017. The formula calculation is called ("field data, @DATATIME, @DATETIME, $func"), and the reference is: ("field data, @DATATIME, @DATETIME, 200017")

[0115] For example, the data standard codes of two data settings are 230020030124TT0322 and 240020030124TT0322. In the configuration screen of the configuration module, the SUM function configuration calculation module is dragged, and the two data standard codes are input into the input end of the calculation module. The indicator standard code of the output end of the calculation module is set to 21TZ1JN110030001. It is determined that the indicator data is generated by the two unique measuring point real-time data (230020030124TT0322, 240020030124TT0322) generated by the preprocessing of the field real-time data. After the calculation module formed by the SUM function configuration, the calculation result, that is, the indicator data, is assigned the standard code 21TZ1JN110030001;

[0116] The chart query value-taking tool uses a linear algorithm and a least squares algorithm to gradually approach the curve value-taking method, and obtains reference standard values ​​for participating index calculations that reflect the actual performance and energy consumption of the unit system or equipment from the unit commissioning or performance test curve or data table.

[0117] For example, the real-time data of the thermal power plant production and operation environment measurement obtained through the SIS system unified interface platform, including the steam temperature 1 (side A pipeline) (KKS code is 10LBA10CT101) in front of the main steam valve of unit 1, the steam temperature 2 (side A pipeline) (KKS code is 10LBA10CT102) in front of the main steam valve of unit 1, and the steam temperature 3 (side A pipeline) (KKS code is 10LBA10CT103) in front of the main steam valve of unit 1 are calculated by calling the function formula of the system configuration calculation module:

[0118] Drag the average calculation function configuration calculation module into the configuration editing screen, fill in the name and KKS code of the steam temperature before the three main steam valves of unit 1# (pipeline on the A side) at each input point of the calculation module input end, and fill in the unique measurement point name 1# unit main steam temperature (pipeline on the A side) at the output end (the standard code is 121302H0230LBA20BR001ZZ0011PFA01RAW00), which forms the unique standard code of the real-time data of the measurement point, that is, the real-time data of the steam temperature before the main steam valve of unit 1# (pipeline on the A side); the configuration calculation method of the real-time data of the main steam temperature (pipeline on the B side) of unit 1# is the same, and its standard code is 121302H0230LBA20BR001ZZ0011PFA01RAW01;

[0119] If the report needs to calculate the main steam temperature index of unit 1#, for simple calculations, the function formula can be directly called:

[0120] #1 unit main steam temperature = daily index real-time data (side A pipeline) ("121302H0230LBA20BR001ZZ0011PFA01RAW00, @DATETIME, @DATETIME, AVG") + daily index real-time data (side B pipeline) ("121302H0230LBA20BR001ZZ0011PFA01RAW01, @DATETIME, @DATETIME, AVG", #1 unit main steam temperature index standard code is 210278, A and B pipeline 1# unit main steam temperature measurement point real-time data standard code is 121302H0230LBA20BR001ZZ0011PFA01RAW00, 121302H0230LBA20BR001ZZ0011PFA01RAW01;

[0121] For complex performance calculations, you need to configure the indicator calculation formula and then call the formula.

[0122] For example, for the indicator 1# unit condensate subcooling, the real-time data of the measuring points involved in the calculation are first calculated by the system configuration calculation module configuration calculation formula:

[0123] For example: drag the average function module configuration calculation module into the configuration editing screen, fill in the name and KKS code of multiple real-time measurement data of the same detection parameter on site at each input point of the calculation module input end, and fill in the name and standard code of the unique measurement point real-time data of the parameter at the output end. In the same way, this forms the unique measurement point real-time data and standard code of multiple different parameters;

[0124] Then, the calculation formula module of the system configuration calculation module (the subcooling degree of condensate water of unit 1) is as follows:

[0125] Drag various mathematical functions into the configuration editing screen to form a subcooling index calculation formula module. Each input point of the formula module input end is filled with the unique real-time data and standard codes of multiple different parameters obtained above, and the output end is filled with the condensate subcooling of index 1# unit and the standard code (the standard code is 210355). This process forms the unique real-time data and standard code of the measuring point, the condensate subcooling index data and standard code of index #1 unit, and the standard code of the condensate subcooling index calculation formula module is manually entered as Per4_tsubCndW.

[0126] The subcooling degree of the main condenser of unit #1 = 0-real-time data of daily index ("Per4_tsubCndW,@DATETIME,@DATETIME,AVG"). The standard code of the subcooling degree index of the main condenser of unit #1 is 210355.

[0127] The data correction module is used to select the recalculated measuring points and indicators and the related measuring points and indicators, and select the reports related to the recalculated measuring points and indicators, specifically by querying the recalculated measuring points and indicators and their related measuring points and indicators and related reports, report generation status and generation time, and after selection, calling the indicator source configuration module or the manual input module to realize the data correction of the measuring points and indicators;

[0128] For example: according to the customer's requirements for the calculation of indicators in the report, the main steam temperature does not participate in the indicator calculation before the unit starts to carry 30% load. Then, according to the time period from the unit to the unit carrying 30% load, the main steam temperature value during this period should be excluded and the indicators related to the main steam temperature calculation should be recalculated;

[0129] For example: when the unit is running, a major turnaround failure suddenly occurs. If the indicators during the failure period need to be analyzed, the indicators within the failure period need to be recalculated;

[0130] For example, during the production process, if a network outage or other fault occurs and affects the accuracy of indicator calculation, all abnormal data and various types of indicators can be recalculated and replaced based on the network outage period.

[0131] The data correction module records the correction log;

[0132] The correction log includes the name of the corrected measuring point and indicator and its related measuring points and indicators, indicator type, report name, report generation status and generation time, correction time, login account and maintainer name.

[0133] For example: the correction log includes: corrected indicator: main steam temperature of unit 1#, correction time 2020.3.1, recalculation time range: 2020.2.18 12:00-2020.2.18 17:32, login account: YYYYY, maintainer: XXX, related indicator names: boiler efficiency of unit 1#, steam consumption rate, power generation coal consumption, power supply coal consumption, turbine efficiency, heat-to-electricity ratio, power generation standard coal consumption, power supply standard coal consumption, related report names: comprehensive daily report of unit 1#, February comprehensive report, turbine daily report, indicator type is comprehensive daily report of unit 1#, turbine daily report indicator is daily indicator, and the indicator of February comprehensive report of unit 1# is monthly indicator;

[0134] For example, for indicator 240985, if the indicator calculation formula of this indicator is modified, all relevant ranges need to be recalculated; if the indicator value is replaced using the indicator source setting module, recalculation is also required.

[0135] The calculation scheduling module is used to schedule and manage the calculation methods of various types and levels of indicators in the system configuration calculation module according to the selection of the data correction module and the configuration requirements of the indicator source configuration module, automatically read the calculation formula of the indicator in the database and the data in the database for calculation, and write the calculation results into the Oracle database, so as to adapt to the requirements of data correction and adjustment calculation under the production and operation environment of the thermal power plant;

[0136] The indicator replacement source configuration module is used to recalculate the recalculated measuring points and indicators and the associated measuring points and indicators selected by the data correction module, as well as the reports related to the selected recalculated measuring points and indicators, and is specifically used to configure the recalculated measuring points and indicators, time range, report range and indicator type, whether to replace the data in the database before recalculation, whether to correct the formula, correction value and data standard value;

[0137] The recalculation configuration in the indicator replacement source configuration module includes recalculation validity configuration, input data status validity configuration, output data status validity configuration, unit operation status configuration, replacement validity configuration, correction formula validity configuration and manual entry validity configuration;

[0138] The recalculation validity configuration is a flag for whether to perform recalculation, which is divided into recalculation valid and recalculation invalid;

[0139] The input data status validity configuration is a flag indicating whether the input data is valid during recalculation, which is divided into valid input data and invalid input data;

[0140] The output data status validity configuration is a flag indicating whether the output data is valid during recalculation, which is divided into output data valid and output data invalid;

[0141] The unit operation status is configured as a sign of the unit operation status within a selected time range, which is divided into shutdown, startup, operation and debugging;

[0142] The replacement validity configuration is a flag for whether to replace the data value before recalculation in the database, which is divided into replacement validity and replacement invalid;

[0143] The validity configuration of the correction formula is a flag indicating whether to modify and recalculate the calculation formula of the measuring point or index and the associated measuring point or index, which is divided into the correction formula being valid and the correction formula being invalid;

[0144] The manual entry validity configuration is a flag indicating whether the manual entry is valid, which is divided into manual entry valid and manual entry invalid.

[0145] The recalculated measuring points and indicators are those that affect the calculation accuracy of indicators during the actual production and operation process or obtained through the SIS system unified interface platform and have been written into the database.

[0146] For example, due to maintenance failure or shutdown restriction, the main steam temperature measurement point of the on-site 1# unit has incorrect statistics or does not meet business requirements, and needs to be recalculated. The data correction module queries and lists all level indicators related to the main steam temperature according to the main steam temperature and standard code of the 1# unit: 1# unit boiler efficiency, steam consumption rate, power generation coal consumption, power supply coal consumption, steam turbine efficiency, thermal power ratio, power generation standard coal consumption, power supply standard coal consumption. The names of the reports where these indicators are located are: 1# unit comprehensive daily report, February monthly comprehensive report, steam turbine daily report and the report generation status and generation time of the current report. Then start to configure the recalculation strategy, select to recalculate the above indicators, select to correct the above report range, and the indicator source configuration module sets the recalculation of the main steam temperature of the 1# unit to be valid, the input data status to be invalid, the output data status to be valid, the correction calculation formula to be invalid, the unit operation status to be shutdown, the replacement validity configuration to be replaced and the manual entry validity configuration to be manually entered. The correction time range is determined according to the failure time of the 1# unit and the report generation time (2020.2.18 12:00-2020.2.18 17:32), determine the indicator type (the comprehensive daily report of unit 1# and the daily report indicator of steam turbine are daily indicators, and the comprehensive report indicator of unit 1# in February is a monthly indicator), and manually input the correction data of the main steam temperature of unit 1#. After confirmation, call the calculation and scheduling module to eliminate, calculate and write data;

[0147] The indicator alternative source configuration module automatically records the alternative source log;

[0148] The replacement source log includes recalculated measuring points and indicators, report data and replacement status, recalculated measuring points and indicators, report data before and after replacement, recalculated indicator type and time range, correction value, corrected calculation formula and selected or entered standard data, login account and maintainer.

[0149] For example: According to customer requirements, the fuel calorific value test data cannot be obtained on the same day, but the provincial company requires that the daily production report must be reported on the same day, so the indicator calculation of the daily report on the same day uses the previous fuel calorific value test data. Therefore, the customer requires: "When the fuel calorific value test data of the day is obtained, the previous fuel calorific value test data must be immediately replaced to recalculate all relevant indicators." The data correction module queries and lists all level indicators related to the fuel calorific value test indicators according to the fuel calorific value test indicators and standard codes, the names of the reports where these indicators are located, and the current report generation status and generation time, and then starts to configure the recalculation strategy, selects the indicators to be recalculated, selects the scope of the report to be corrected, and the indicator replacement source configuration module sets the recalculation validity configuration of the fuel calorific value test indicators to valid, the input data status to invalid, the output data status to valid, the unit operation status to start, and the replacement The replacement validity configuration is set to replacement validity, the correction formula validity configuration is set to invalid, and the manual entry validity configuration is set to valid. According to the completion time of the fuel calorific value test and the report generation time, the correction time range is determined to be between the report generation time and the fuel calorific value data issuance time, and the type of replacement indicator in the report is determined. The manual entry module enters the fuel calorific value test data, and after confirmation, the calculation scheduling module is called to delete, calculate and write data; the name of the corrected fuel calorific value test indicator and its related indicators, indicator type, report name, report generation status and generation time, correction time, login account and maintainer name are automatically recorded in the correction log, and the fuel calorific value test data before and after replacement, all levels of indicator data related to the fuel calorific value test indicator, the name and indicator type of the report where these indicators are located, the fuel calorific value test completion time, report generation time, login account and maintainer are automatically recorded in the replacement source log.

[0150] The manual input module is used to manually input the correct data and formulas that need to be corrected and replaced by the data correction module and the indicator source configuration module;

[0151] For example: due to the startup restriction of the on-site main steam temperature measurement point, the main steam temperature index data statistics do not meet the requirements of business statistical analysis and need to be recalculated. The data correction module selects the main steam temperature index, all indicators related to the main steam temperature index, and the name of the report where these indicators are located, the current report generation status, and the generation time, and then configures the recalculation strategy, selects and corrects all main steam temperature related indicators and reports, and confirms the indicator replacement source configuration module. The main steam temperature of unit 1 is set to recalculate effectively, the input data status is set to invalid, the output data status is set to valid, the correction calculation formula is set to invalid, the unit operation status is set to startup, the replacement validity configuration is set to replacement valid, and the manual entry validity configuration is set to manual entry valid. Query the DCS system to determine the start time and arrival time settings of unit 1 from startup to 30% load. Correct the time range, determine the type of replacement indicator in the selected report, manually input the correction data of the main steam temperature of unit 1#, and manually input the main steam temperature of unit 1# in this time period as 0. After confirmation, the calculation and scheduling module recalculates and writes the result data into the database. The name, indicator type, report name, report generation status and generation time, correction time, login account and maintenance person name of the corrected main steam temperature indicator of unit 1# and its related indicators are automatically recorded in the correction log. The main steam temperature data of unit 1# before and after replacement, all level indicator data related to the main steam temperature indicator of unit 1#, the name and indicator type of the report where these indicators are located, the start time and arrival time of unit 1# from startup to 30% load, the generation time of related reports, the login account and maintenance person are automatically recorded in the replacement source log.

[0152] The indicator tracking module includes an indicator calculation hierarchical association diagram module, a query associated indicator and data module, an indicator over-limit alarm module and a hierarchical comparison module of cascade indicators at all levels, which is conducive to tracing and locating the production and operation problems of abnormal indicators step by step;

[0153] The indicator calculation level association diagram module is used to graphically display the cascade levels and relationships of indicator calculations at all levels and their data;

[0154] The query related indicators and data module is used to query the actual calculation formula of the indicator and the names, indicator standard codes, data, and calculation formulas of other indicators involved in the calculation in the formula according to the indicator standard code and type;

[0155] The indicator over-limit alarm module is used for displaying the color of the over-limit indicator;

[0156] The hierarchical comparison module of cascading indicators at each level is used to compare indicators at the same level by dragging and dropping to form a comparison graph, so as to locate the source of production and operation problems.

[0157] The cascade indicator levels are displayed recursively. After dragging, the indicators must be compared at the same level. For example, indicators 240079 are compared with 230079. 240079 is obtained from 240032 and 240017, and 230079 is obtained from 230032 and 230017. When comparing, 230032 needs to be compared with 240032, and 2300172 needs to be compared with 240017.

[0158] This application can improve the accuracy and precision of indicators of real-time measurement and laboratory data calculation in actual business systems that change due to complex factors such as time adjustment, test time, equipment defects, system failures, scheduling management, equipment adjustment, metering equipment installation location, medium leakage, corrosion, load state changes, business adjustments, etc., improve efficiency, reduce labor costs, ensure the authenticity and reliability of production and operation indicators and the traceability of abnormal indicators, quickly discover abnormal indicators, and improve the timeliness of production and operation indicator analysis and the economic benefits of power plants.
