when the charged number of the valve control system sub-modules is smaller than a set number threshold, reading fault records of the valve control system sub-modules;
when the fault record of the submodule in the valve control system has a fault, the submodule is prevented from entering detection, entering an overhaul mode and simultaneously starting to record overhaul time.
After step 1, the method further comprises:
the charged number of the sub-modules in the valve control system is obtained again;
judging whether the overhaul time is greater than a preset time threshold according to the overhaul time;
when the overhaul time is greater than a preset time threshold or the number of the newly acquired electrified sub-modules in the valve control system is greater than the number threshold, exiting from an overhaul mode;
the maintenance of the sub-module in the traditional mode is to manually control the whole sequential control flow and judge the whole sequential control flow by naked eyes, manually issue the command to enter a maintenance mode through an interface, manually exit the maintenance mode after the test is finished and enter a normal operation mode by default to update the state of the sub-module; different from the traditional overhaul mode, the invention judges the converter valve control system after receiving the instruction, and can enter the overhaul mode when the whole valve tower sub-module is not in a charging state, or can not enter the overhaul mode; the control system of the converter valve can be ensured to correctly enter the maintenance mode through error entry prevention detection, and meanwhile, the maintenance mode is automatically exited when the maintenance time reaches a specified time threshold or the charged number of the submodules is detected to reach the threshold through recording the maintenance time, and the submodules are updated and immediately enter the normal mode.
As shown in fig. 3, step 2 includes:
judging whether the sub-module with the fault is in a normal working state or not according to the voltage value of the sub-module with the fault;
when the sub-module with the fault is not in a normal working state, an alarm instruction is sent;
and when the sub-module with the fault is in a normal working state, judging whether the sub-module with the fault is in a power-off state.
The judging whether the sub-module with the fault is in a power-off state comprises the following steps:
detecting whether the voltage value of the submodule accords with a capacitor voltage detection curve corresponding to the submodule according to the voltage value of the submodule with the fault;
when the voltage value of the sub-module with the fault accords with a capacitor voltage detection curve corresponding to the sub-module, judging whether the sub-module with the fault is in a voltage drop state or not;
when the sub-module with faults is in a voltage drop state, the sub-module with faults is in a power-off state;
and when the failed submodule is not in a voltage drop state, the failed submodule is not in a power failure state.
The step of judging whether the sub-module with the fault is in a normal working state according to the voltage value of the sub-module with the fault comprises the following steps:
judging whether the voltage value of the sub-module with the fault is larger than a set sub-module voltage threshold according to the voltage value of the sub-module with the fault;
when the voltage value of the sub-module with the fault is larger than the voltage threshold value of the sub-module, acquiring the charging completion condition of the sub-module with the fault;
when the charging of the sub-module with the fault is completed, the sub-module with the fault is in a normal working state;
when the sub-module with the fault is not charged, the sub-module with the fault is not in a normal working state;
when the error-entering prevention detection is passed, the voltage value of the failed submodule in the valve control system is obtained in real time, and when the control logic of the converter valve control system is used for detecting the failed ith submodule voltage U smi Is larger than the voltage threshold U corresponding to the set ith sub-module seti And when the valve control system automatically checks whether the submodule is in a normal working state by sending a Heartcoat signal.
As shown in fig. 4, the determining whether the sub-module that has failed is in a voltage drop state includes:
detecting whether the voltage value of the sub-module with the fault works in a set working range;
when the voltage value of the sub-module with the fault does not work in the set working range, judging whether the voltage value of the sub-module with the fault is smaller than the voltage threshold of the sub-module;
and when the voltage value of the failed submodule is smaller than the voltage threshold value of the submodule, the failed submodule is in a voltage drop state.
In step 3, by detecting the ith sub-module voltage U smi The voltage is smaller than the set voltage threshold U of the ith sub-module seti When the converter valve control system judges that the voltage of the submodule is in a gradual power-off state, automatically issues a trigger command to the corresponding submodule, receives the state returned from the submodule, automatically detects whether the trigger command is identical with the issued trigger command and sets corresponding alarm information.
Step 4: comprising the following steps:
when the issued turn-off or turn-on instruction is consistent with the return state corresponding to the submodule, the submodule passes maintenance;
when the issued turn-off or turn-on instruction is inconsistent with the return state corresponding to the submodule, the submodule fails to be overhauled;
in summary, the method for automatically overhauling the submodule by valve control mainly comprises four functions, namely intelligent misoperation prevention, submodule working state detection, automatic command triggering and identification and automatic exiting of an overhauling mode; based on the functions, the invention has the following beneficial effects:
(1) Anti-misoperation and automatic exit from overhaul mode: compared with the existing method, the method has the advantages that under the normal operation working condition of the valve control system, whether the maintenance mode can be entered is judged by automatically detecting the voltage value of the sub-module with faults in the valve control system, so that the maintenance efficiency can be improved; meanwhile, the time limit is set to automatically exit the overhaul mode and update the state of the sub-module, so that the safety problem caused by forgetting to exit the overhaul mode can be effectively prevented;
(2) Active and sub-module interactions: according to the invention, through the communication between the automatic retrieval valve control system and the submodule, a control instruction is automatically issued according to the working state and the voltage of the submodule, and whether the submodule passes the overhaul is detected according to the return state of the submodule, so that the problem of error issuing caused by manual operation is avoided, the overhaul reliability is improved, and the method has the characteristics of convenience, rapidness and reliability;
(3) The design is simple: the invention does not relate to the change of the architecture of the valve control system and the communication optical fiber, and can be realized by only adding judgment and triggering logic on software, thereby reducing the running and maintenance cost of equipment;
(4) Auxiliary operator judgment: taking a waveform diagram triggered autonomously in a valve control system as an example, as shown in fig. 5, the abscissa represents time in ms, and the ordinate represents the on or off state of a sub-module, and the traditional maintenance method is characterized in that the trigger waveform of the sub-module is subjected to artificial analysis and judgment to finally obtain a maintenance result of the sub-module, so that the maintenance efficiency is low; according to the invention, whether the trigger instruction issued by the valve control system is consistent with the return state of the submodule or not is automatically compared, and the automatic maintenance result is actively informed, so that the maintenance efficiency is improved, and the probability of manual misoperation is reduced.
