Description

Technical Field

[0001] The invention relates to the technical field of nuclear power plant overhaul planning, and in particular to a nuclear power plant overhaul planning system. Background Art

[0002] Nuclear power plant overhaul planning is an important reference for the formulation of nuclear power plant fuel planning, power generation planning and operating indicators. In addition to meeting the needs of the power grid, nuclear power plant overhaul planning must also consider the safety and economy of the nuclear power plant and is subject to the fuel cycle length of the unit.

[0003] At present, nuclear power plant overhaul planning is mainly calculated by using EXCEL tables, and the nuclear power plant overhaul planning map is drawn through the charts of EXCEL tables for display. This method has the following problems:

[0004] 1. All elements required for the nuclear power plant overhaul plan need to be entered one by one in the EXCEL table, resulting in low efficiency of the nuclear power plant overhaul plan. When the nuclear power plant overhaul plan is adjusted across years, the calculation formula needs to be adjusted, which is prone to errors.

[0005] 2. When using EXCEL table charts to draw nuclear power plant overhaul planning maps, it is necessary to copy data and a series of complex data references and formulas to generate charts and text information on the charts. The text information that can be displayed on the charts is also relatively limited. In order to obtain a better chart display effect, it is also necessary to constantly try and adjust the size, position and color of the charts.

[0006] 3. In order to obtain an overhaul plan that is more beneficial to the operating performance of the nuclear power plant and meets the requirements of the power grid, it is necessary to compare multiple overhaul planning schemes.

[0007] The existing nuclear power plant overhaul planning method has the above problems and cannot meet the requirements of nuclear power plant overhaul planning throughout its life cycle. At the same time, the display of nuclear power plant overhaul planning data is not intuitive and comprehensive, and non-overhaul planning personnel cannot easily obtain nuclear power plant overhaul planning data.

[0008] With the continuous improvement of the requirements for refined nuclear power plant overhaul management, it is necessary to take into account all factors that affect the overhaul planning of nuclear power plants and develop a new overhaul planning method for nuclear power plants to achieve convenient calculation and adjustment of nuclear power plant overhaul plans and intuitive and comprehensive display of nuclear power plant overhaul planning data. This will not only help overhaul planners to prepare nuclear power plant overhaul plans, but also better and more conveniently serve non-overhaul planners and provide a reference for fuel planning, power generation planning, and the formulation of operating indicators. Summary of the invention

[0009] One of the purposes of the present invention is to provide a nuclear power plant overhaul planning system to solve the problems of multiple data entry, low efficiency and easy errors in the existing nuclear power plant overhaul planning method, realize automatic planning of nuclear power plant overhaul, improve the efficiency of nuclear power plant overhaul planning, and avoid errors in nuclear power plant overhaul planning.

[0058] The annual planned overhaul times of a nuclear power plant is the sum of the annual planned overhaul times of each unit in the nuclear power plant. The annual planned overhaul times of each unit in the nuclear power plant is the number of overhaul times of each unit in the nuclear power plant that are planned to start in the current year.

[0059] The annual planned overhaul days of a nuclear power plant are the sum of the annual planned overhaul days of each unit of the nuclear power plant, and the annual planned overhaul days of each unit of a nuclear power plant are the sum of the overhaul durations of each overhaul planned annually for each unit of the nuclear power plant; when the planned overhauls of each unit of a nuclear power plant span multiple years, the overhaul duration of the annual planned overhauls of each unit of the nuclear power plant shall be calculated separately according to the year in which they are located;

[0060] The annual planned equivalent million-kilowatt overhaul days of a nuclear power plant is the sum of the annual planned equivalent million-kilowatt overhaul days of each unit of the nuclear power plant. The annual planned equivalent million-kilowatt overhaul days of each unit of a nuclear power plant = the annual planned overhaul days of each unit of the nuclear power plant × the rated power of each unit of the nuclear power plant / the rated power of the million-kilowatt unit of the nuclear power plant;

[0061] The annual planned capacity factor of a nuclear power plant is the average of the annual planned capacity factors of each unit in the nuclear power plant;

[0062] When each unit of a nuclear power plant has a planned overhaul each year, the annual planned capacity factor of each unit of the nuclear power plant = ((annual calendar days - annual planned overhaul days of each unit of the nuclear power plant - annual planned overhaul start-up and shutdown loss days of each unit of the nuclear power plant - annual planned tuning test loss days of each unit of the nuclear power plant) / annual calendar days) × 100%;

[0069] The annual planned overhaul days for each unit of a nuclear power plant is the sum of the overhaul durations of each annual planned overhaul for each unit of the nuclear power plant.

For example, if the overhaul duration of a certain overhaul planned by a unit of a nuclear power plant is 30 days, of which 10 days fall in 2022 and 20 days fall in 2023, then when calculating the planned overhaul days of the unit of the nuclear power plant in 2022, the planned overhaul duration of the unit of the nuclear power plant is 10 days; when calculating the planned overhaul days of the unit of the nuclear power plant in 2023, the planned overhaul duration of the unit of the nuclear power plant is 20 days.

[0071] In this embodiment, as one of the feasible ways, the calculation module identifies the overhaul planning data of the nuclear power plant whose overhaul start time and overhaul end time fall into the Spring Festival, the peak summer period and the peak winter period, and the overhaul planning data with overlap, and calculates the overlapping data of the overhaul planning data with overlap in the overhaul planning data of the nuclear power plant, including the overhaul numbers of the overlapping overhauls and the number of overlapping days; the display module marks the overhaul planning data of the nuclear power plant overhaul planning data whose overhaul start time and overhaul end time fall into the Spring Festival, the peak summer period and the peak winter period, and the overhaul planning data with overlap on the overhaul planning map of the nuclear power plant, and displays the overlapping data of the overhaul planning data with overlap in the overhaul planning data of the nuclear power plant on the overhaul planning map.

[0072] In this embodiment, as one of the feasible ways, the display module is provided with an editable overhaul planning page and a release version overhaul planning page; both the editable overhaul planning page and the release version overhaul planning page are provided with a "time interval" input box for entering a time interval; the time interval includes a start year and an end year; when the time interval is not entered in the time interval input box, the time interval is a default value; when the time interval is entered in the time interval input box, the time interval is an input value; the display module generates overhaul planning statistical data within the nuclear power plant time interval according to the overhaul planning data within the nuclear power plant time interval and displays it on the corresponding overhaul planning page, and generates an overhaul planning diagram within the nuclear power plant time interval according to the overhaul planning data within the nuclear power plant time interval and displays it on the corresponding overhaul planning page.

[0073] In this embodiment, as one of the achievable methods, when no time interval is entered in the "time interval" input box, the starting year defaults to the current year and the ending year defaults to 4 years after the current year.

[0074] In this embodiment, as one of the feasible ways, both the edited overhaul planning page and the published overhaul planning page are provided with a "full life cycle" query button; click the "full life cycle" query button, and the display module generates overhaul planning statistical data for the full life cycle of the nuclear power plant based on the overhaul planning data for the full life cycle of the nuclear power plant, and refreshes and displays it on the corresponding overhaul planning page, and generates an overhaul planning diagram for the full life cycle of the nuclear power plant based on the overhaul planning data for the full life cycle of the nuclear power plant, and refreshes and displays it on the corresponding overhaul planning page.

[0075] In this embodiment, as one of the achievable methods, the edit version overhaul planning page is provided with a "Spring Festival, Peak Summer Period and Peak Winter Period" setting window for setting the start and end time of the Spring Festival, Peak Summer Period and Peak Winter Period; the edit version overhaul planning page and the release version overhaul planning page are both provided with "Spring Festival, Peak Summer Period and Peak Winter Period" display options;

[0076] After checking the "Spring Festival, Peak Summer and Peak Winter" display option, the calculation module identifies the overhaul planning data within the time interval or the entire life cycle of the nuclear power plant whose overhaul start time and overhaul end time fall within the Spring Festival, peak summer and peak winter periods; the display module marks the overhaul planning data within the time interval or the entire life cycle of the nuclear power plant whose overhaul start time and overhaul end time fall within the Spring Festival, peak summer and peak winter periods with color ribbons on the overhaul planning diagram within the time interval or the entire life cycle of the nuclear power plant.

[0077] Summer and winter are generally the peak periods for electricity consumption in the power grid. The power grid has relevant requirements on whether overhaul can be arranged during the peak summer and peak winter periods. The overhaul planning data that uses color bands to mark the overhaul start time and the overhaul end time that fall into the peak summer and peak winter periods is convenient for overhaul planners to identify the overhauls related to the peak summer and peak winter periods during overhaul planning, so as to make appropriate adjustments to meet the overhaul planning requirements.

[0078] The Spring Festival is a period of low electricity consumption for the power grid. The power grid will require some units of the nuclear power plant to participate in mediation, and the power grid's start and shutdown requirements for units during the Spring Festival are also different from usual times. Nuclear power plants must also consider human resource arrangements when arranging overhauls during and around the Spring Festival. The overhaul start time and overhaul end time are marked with color bands and included in the overhaul planning data for the Spring Festival, making it convenient for overhaul planners to identify overhauls related to the Spring Festival during overhaul planning so that appropriate adjustments can be made to meet the overhaul planning requirements.

[0079] In this embodiment, as one of the achievable ways, both the editing version overhaul planning page and the publishing version overhaul planning page are provided with an "overlapping overhaul" highlighting option;

[0080] After checking the "Overlapping Overhaul" highlight option, the calculation module identifies the overhaul planning data with overlapping overhaul start time and overhaul end time in the overhaul planning data within the time interval or within the whole life cycle of the nuclear power plant, and calculates the overlapping data of the overhaul planning data with overlapping overhaul start time and overhaul end time in the overhaul planning data within the time interval or within the whole life cycle of the nuclear power plant; the display module marks the overhaul planning data with overlapping overhaul start time and overhaul end time in the overhaul planning data within the time interval or within the whole life cycle on the overhaul planning diagram within the time interval or within the whole life cycle of the nuclear power plant with a color band, and displays the overlapping data of the overhaul planning data with overlapping overhaul start time and overhaul end time in the overhaul planning data within the time interval or within the whole life cycle on the overhaul planning diagram within the time interval or within the whole life cycle of the nuclear power plant.

[0081] On the overhaul planning page, there is an option to highlight "overlapping overhauls" to prompt overhaul planners to assess whether it is necessary to re-plan the overlapping overhauls.
