In some embodiments, when the fault repair decision module 400 of the power station health management system generates a repair and maintenance plan, the repair decisions can be divided into two broad categories, emergency repair and preventative repair; preventive maintenance is divided into regular maintenance and state monitoring maintenance. The maintenance of the power station is designed according to a base-level and base-level two-stage maintenance system, and in order to ensure that the maintenance is carried out smoothly, the power station is compiled with a use and maintenance specification for a user to maintain. Meanwhile, when a fault of a base level occurs, a user can carry out primary maintenance on the power station according to the self health management content of the power station, and if the fault cannot be solved, the user needs to report the maintenance of the power station. The superior maintenance unit needs to maintain the power station according to the use and maintenance instruction.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a troubleshooting decision module according to an embodiment of the present disclosure.
Illustratively, the troubleshooting module 400 includes a predictive maintenance items unit 410 for generating a predictive maintenance items plan based on the maintenance protocol when the plant health level is healthy and the health status prediction information is a health degradation status.
Illustratively, the predicted maintenance project plan generated by the predicted maintenance project unit 410 includes a condition monitoring predicted maintenance project, a prediction judgment can be made based on the diagnosis and prediction results of the health condition of the power station, and if the health condition thereof is degraded, a maintenance project list can be generated, including materials to be prepared (including spare parts and tools, selecting a maintenance plan, making specific maintenance work standards, etc.). Maintenance teams or maintenance personnel at corresponding maintenance levels can maintain or adjust the power station according to maintenance item lists, and state parameter values which possibly cause power station faults are adjusted or restored to be in a normal range. If the degradation of the health state of the power station belongs to the system problem in the aspect of design and manufacture, the degradation of the health state of the equipment can be reflected to an equipment management department while maintenance is carried out, and a basis is provided for the improvement and development planning of the equipment model.
Illustratively, the troubleshooting module 400 further includes a scheduled maintenance unit 420 for generating a scheduled maintenance project plan according to a maintenance plan when the health level of the power plant is healthy and the health status prediction information is in a health maintenance status.
Illustratively, the scheduled maintenance project plan generated by the scheduled maintenance unit 420 may be used to determine the health status of the power station based on the diagnosis and prediction of the health status of the power station, and if all monitoring parameters of the power station are within normal ranges, the power station is routinely maintained according to the scheduled maintenance projects, such as clean maintenance electrical maintenance, mechanical maintenance, air filter replacement, diesel filter replacement, oil filter replacement, diesel oil replacement, engine oil replenishment, engine oil replacement, oil filter cleaning, fuel tank cleaning, coolant radiator inspection and cleaning, battery maintenance, battery replacement, belt inspection and replacement, insulation resistance inspection, fuel pipe inspection and replacement, rubber part replacement, oil level inspection, cooling liquid replacement, thermostat inspection, temperature control, and the like, The oil-water separator is used for discharging precipitated water and the like.
It should be understood that the specific items and time intervals for routine maintenance can be set according to actual conditions, and are not described in detail herein.
For example, all scheduled maintenance items may be setup for maintenance cycle time and use via a setup menu.
Illustratively, after each power-on self-test of the power station is normal, the software interface of the health management system first reminds the user of daily maintenance projects and the time until the next regular maintenance. When the maintenance item is clicked, the operation guidance page of the maintenance item can be entered. And after the maintenance project is confirmed to be completed, inputting a password of an administrator, and then the regular maintenance reminding project is not displayed before the next maintenance, or reminding is carried out before starting up every time. And after the power station is shut down, if the time for the next regular maintenance is less than 24h (adjustable), the software interface of the health management system reminds the operator again.
Illustratively, the troubleshooting decision module 400 also includes an emergency maintenance unit 430 for generating an emergency maintenance project plan based on the maintenance protocol when the plant health rating is one of sub-health/early warning/failure.
Illustratively, the emergency maintenance project plan generated by the emergency maintenance unit 430 means that the health management system cannot be predicted by prior testing or monitoring, and has no prior obvious symptoms, nor random failures of the development process. When the faults occur, the most reasonable maintenance measures are required to be applied to complete fault positioning and maintenance work in the shortest time, and normal operation of the power station is realized. Aiming at the faults, the health management system establishes a three-stage maintenance fault diagnosis database of the power station according to a maintenance task allocation table, determines required technical files, tools and detection and diagnosis equipment, guides to complete fault positioning and provides guidance of a maintenance method. The equipment maintenance personnel can be guided to complete fault positioning and maintenance by combining the displayed maintenance information according to the emergency maintenance project plan given by the power station health management system.
In some embodiments, the health status evaluation module 200 obtains the operating status data of the power station through online monitoring of the status monitoring module 100, so as to evaluate the status of the power station, determine the health level of the power station, and give an alarm to related equipment users, maintenance personnel or management personnel, where the health level of the power station is set to four statuses of health, sub-health, early warning and failure.
In some implementation scenes, each time the power station is connected with a direct-current power supply, the system self-check evaluates the health state of the power station before starting; after the power station is shut down, a 'one-key evaluation' button can be clicked to evaluate the health state of the power station during the current operation. Through data comparison and analysis, the power station is evaluated to be healthy, the system does not give any prompt, and the power station does not need to be maintained. And if the power station is found to be in three states of sub-health, early warning and fault through evaluation, reminding is given through an evaluation interface.
Exemplarily, a preset parameter standard value and sub-health, early warning and fault threshold values can be set before data comparison and analysis; and comparing all monitored operation parameters with a set threshold value in the power-on self-test and operation processes of the power station so as to obtain the conclusion of the health state grade. Parameters can be preset in advance, including which parameters are in a sub-health state, which data overrun early warning and the like; of course the acquisition analysis time period for each parameter is different, e.g. the sub-healthy continuous acquisition period may be ten minutes and the faulty continuous acquisition period may be 3 seconds. The number of times of use of partial switching value signal data is counted according to the number of times, partial switching value fault information is input and just confirmed to be a fault, and a part of faults are determined to be fault, early warning or sub-health according to different analog values, switching value information and a preset logic relation.
In some embodiments, the health management interface of the power station health management system may be divided into two health assessment modes, i.e., power-on self-test and one-key assessment. And clicking a power-on self-test button before starting the computer, and entering a power-on self-test page. Through evaluation, when the power station is in a healthy state, the power station does not need to be maintained and can be directly started. After the power station is stopped after the operation of the power station is finished every time, the operation condition of the power station can be evaluated, and the user only needs to click one-button evaluation in a health management page.
Illustratively, when partial devices or auxiliary functions of the power station fail, such as electric fuel pump failure, mains supply charging failure, regular maintenance and maintenance time is up, the number of times of using the devices exceeds 80% (which can be set) of a rated value, the voltage of a storage battery is low, a fault detection relay, frequency, oil pressure, voltage and other parameters are out of tolerance and do not reach an early warning value, and the like, the normal operation and the electrical performance of the power station are not affected, the power station can normally supply power, a health management system is defined as a sub-health state, a sub-health indicator lamp on a power station health assessment picture is changed into yellow, a maintenance plan needs to be arranged according to maintenance decision requirements, and maintenance is carried out according to maintenance and maintenance guidance.
Illustratively, when the operating parameters of the power station part exceed standard ranges, such as fuel level low warning, cooling liquid temperature high warning, voltage abnormity warning, environment temperature high warning and the like, normal power supply can still be carried out for a short time, but if no measures are taken, performance deterioration can be caused, and functions or performance can be affected. The health management system is defined as an early warning state, and an indicator lamp of an early warning item on a power station health assessment picture is changed into orange, which means that if no important task is executed, measures need to be taken in time according to maintenance and maintenance guidance or power failure shutdown, inspection and maintenance are required.
For example, when the main function or performance of the power station fails, such as short circuit, low oil pressure, overspeed fault, failure of closing the power supply circuit breaker, etc., the power supply circuit breaker is opened or shut down, and normal power supply cannot be performed. The health management system is defined as a fault state, and a 'fault item' indicator lamp on a power station health assessment picture turns red to indicate that power-off maintenance is required immediately.
