Detailed Description
The embodiment of the invention provides a method, a device and equipment for testing the effectiveness of a cooling water conductivity protection function, which are used for solving the technical problem of how to test the cooling water conductivity protection function in a valve cold control protection system of a flexible direct current converter valve.
In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a method for testing effectiveness of a cooling water conductivity protection function. The method is based on a preset valve cold test system, the valve cold test system comprises three valve cold test modules which are identical in structure and independent from each other, each valve cold test module comprises a cooling water pipeline, a deionizing device for removing cooling water ions in the cooling water pipeline and sensors for detecting the conductivity of the cooling water in the cooling water pipeline, and each sensor is connected with a valve cold control protection system to send the measured value of the conductivity of the cooling water to the valve cold control protection system.
The valve cooling test system can be specifically designed based on the actual structural condition of the valve cooling system of the flexible direct current converter valve, and specific structures of the cooling water pipeline and the deionizing device can refer to the prior art, and in the embodiment, the valve cooling test system is not limited.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for testing effectiveness of a protection function of conductivity of cooling water according to an embodiment of the present invention.
The method for testing the effectiveness of the conductivity protection function of the cooling water provided by the embodiment of the invention comprises the steps S1-S11.
And S1, controlling three deionizing devices of the valve cold test system when the valve cold control protection system and the valve cold test system are in a stable running state, so that the deviation of the cooling water electrolysis rate and the conductivity rated value detected by each sensor of the valve cold test system is within a preset deviation range.
As an embodiment, at the beginning of the test, the valve cold control protection system and the valve cold test system may be activated simultaneously by manual means and operated to a steady operation state.
The preset deviation range can be set according to actual conditions. To ensure the accuracy of the test, it is necessary to bring the conductivity of the cooling water detected by each sensor around the conductivity rating, so that the preset deviation range should take a value of not more than 5%. As one embodiment, the preset deviation range is set to 5%.
The conductivity rating may be derived from design parameters associated with the valve cooling system of the flexible direct current converter valve, and is typically less than the cooling water conductivity overrating warning setpoint.
And S2, selecting one deionizing device from the three deionizing devices as a first control target, and controlling the first control target to enable the conductivity of cooling water in a corresponding cooling water pipeline to be increased until the cooling water conductivity detected by a corresponding sensor is larger than a cooling water conductivity too high alarm fixed value and smaller than the cooling water conductivity too high lockout trip fixed value.
And step S3, detecting whether a message for prompting the too high conductivity of the cooling water is displayed on a background monitoring interface of the valve cold control protection system after the actually measured value of the conductivity of the cooling water detected by each sensor is sent to the valve cold control protection system, and obtaining a first detection result.
If the cooling water conductivity protection function of the valve cold control protection system is normal, a background monitoring interface of the valve cold control protection system should not display a message for prompting the too high cooling water conductivity alarm.
And S4, selecting one deionizing device from the rest deionizing devices except the first control target as a second control target, and controlling the second control target to enable the cooling water conductivity in the corresponding cooling water pipeline to be increased until the cooling water conductivity detected by the corresponding sensor is larger than the cooling water conductivity too high alarm fixed value and smaller than the cooling water conductivity too high locking trip fixed value.
And S5, detecting whether the background monitoring interface displays a message for prompting the too high cooling water electric rate alarm or not when the timing time length after the actually measured cooling water electric rate values detected by the sensors are sent to the valve cold control protection system exceeds a first preset time threshold value, and obtaining a second detection result.
If the cooling water conductivity protection function of the valve cold control protection system is normal, a background monitoring interface of the valve cold control protection system should display a message for prompting the too high cooling water conductivity alarm so as to warn corresponding operation and maintenance personnel.
And S6, controlling the first control target and the second control target to enable deviation of the cooling water electric conductivity rate in the corresponding cooling water pipeline and the electric conductivity rated value to be within a preset deviation range, and resetting the valve cold control protection system.
After the valve cold control protection system sends the message, the message will be latched at the background monitoring interface, so in order to restore the valve cold control protection system to the original normal state again, the valve cold control protection system needs to be reset in step S6, so that the message latched at the background monitoring interface is removed.
And S7, controlling the first control target to enable the cooling water conductivity in the corresponding cooling water pipeline to be increased until the cooling water conductivity detected by the corresponding sensor is greater than the cooling water conductivity too high locking trip fixed value.
And S8, detecting whether an outlet of the valve cold control protection system is blocked and tripped and whether a background monitoring interface displays a message for prompting the blocking and tripping of the too high cooling water electric power rate after the actually measured cooling water electric power rate value detected by each sensor is sent to the valve cold control protection system, so as to obtain a third detection result.
If the cooling water conductivity protection function of the valve cold control protection system is normal, the valve cold control protection system should not output a locking tripping signal and the background monitoring interface should not display a message for prompting the locking tripping of the too high cooling water conductivity.
And S9, taking the deionization devices except the first control target and the second control target in the three deionization devices as a third control target, and controlling the third control target to enable the cooling water conductivity in the corresponding cooling water pipeline to be increased until the cooling water conductivity detected by the corresponding sensor is larger than the cooling water conductivity too high locking trip fixed value.
And step S10, detecting whether the valve cold control protection system outputs a locking tripping signal or not and whether a background monitoring interface displays a message for prompting locking tripping when the cooling water conductivity is too high or not when the timing time length after the actually measured value of the cooling water conductivity detected by each sensor is sent to the valve cold control protection system exceeds a second preset time threshold value, so as to obtain a fourth detection result.
If the cooling water conductivity protection function of the valve cold control protection system is normal, the valve cold control protection system should output a blocking trip signal and the background monitoring interface should display a message for prompting the blocking trip with the excessively high cooling water conductivity.
And S11, judging whether the effectiveness test of the cooling water electric power protection function of the valve cold control protection system is passed or not according to the obtained first to fourth detection results, and obtaining a corresponding test result.
In one implementation manner, the determining, according to the obtained first to fourth detection results, whether the validity test of the cooling water electrical conductivity protection function of the valve cold control protection system passes or not, to obtain a corresponding test result includes:
when the first to fourth detection results meet the test passing conditions, judging that the effectiveness test of the cooling water electric power protection function of the valve cold control protection system is passed;
the test passing conditions are:
the first detection result is that the background monitoring interface does not display a message for prompting the too high cooling water electric power alarm;
the second detection result is that the background monitoring interface is provided with a message for prompting the too high cooling water electric power alarm;

and the fourth detection result is that the valve cold control protection system has an outlet locking tripping signal and the background monitoring interface has a message for prompting locking tripping with overhigh cooling water electrolysis rate.

In one implementation, on the basis of the method shown in fig. 1, as shown in fig. 2, the method further includes:
and step S12, outputting information for prompting the end of the test and the failure of the validity test of the cooling water electric power protection function of the valve cold control protection system when any one of the first to fourth detection results does not meet the test passing condition.
