Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

Fig. 1 is a flow chart illustrating a method for calculating a real-time hydrogen leakage rate of a generator according to an exemplary embodiment. The method can be applied to a terminal device, the terminal device can be, for example, a personal computer, a server, etc., the pump disclosure does not limit the type of the terminal device, as shown in fig. 1, and the method includes:

step 100, determining a gas supplementing time period within a preset time period, wherein the gas supplementing time period is a time period for supplementing hydrogen to a cooling system of a hydrogen cooling generator set;

as an example of this embodiment, step 100 comprises:

in the preset time period, if the gas pressure acquired at a plurality of continuous sampling moments is sequentially and continuously increased, taking the earliest sampling moment in the plurality of continuous sampling moments as the starting moment of the gas supplementing time period;

and in the preset time period, if the gas pressure acquired at a certain sampling moment after the starting moment is lower than the gas pressure acquired at a sampling moment before the sampling moment, taking the sampling moment as the ending moment of the gas supplementing time period.

Step 101, determining a pressure correction added value according to the gas pressure, the gas temperature and the atmospheric pressure acquired at the moment before and after the gas supplementing time period, wherein the gas pressure is the pressure of the gas in the cooling system, the gas temperature is the temperature of the gas in the cooling system, and the atmospheric pressure is the atmospheric pressure of the environment where the cooling system is located;

as an example of this embodiment, step 101 includes:

and determining the pressure correction increase value according to the gas pressure, the gas temperature and the atmospheric pressure acquired at the sampling moment immediately before the air supplementing time period and the gas pressure, the gas temperature and the atmospheric pressure acquired at the sampling moment immediately after the air supplementing time period.

For example, the pressure correction increment due to the air supply period may be determined according to equation one.

Wherein, the delta P is a pressure correction increasing value, P₁The pressure of the gas (in KPa (G)) acquired at the sampling time immediately before the gas supply period₁The gas temperature (in DEG C) collected at the sampling moment immediately before the gas supplementing time period is B₁Atmospheric pressure (in KPa (A)) acquired at a sampling time immediately before the gas supply period₂The pressure of the gas (in KPa (G)) acquired at the sampling time immediately after the gas supply time interval₂The gas temperature (in degrees C) collected at the sampling moment immediately after the gas supplementing time period is B₂And correcting the hydrogen pressure of each sampling point in the adjacent interval to obtain the atmospheric pressure acquired at the sampling moment immediately after the gas supplementing time interval, wherein the unit of the hydrogen pressure is KPa (A)).

102, aiming at each sampling moment in the preset time period, performing the following operations to obtain the gas leakage rate corresponding to each sampling moment: wherein step 102 may include:

step 1020, taking the sampling time before the preset time duration of the sampling time as a calculation starting time, and taking a time period between the calculation starting time and the sampling time as a sub-time period corresponding to the sampling time, wherein the preset time duration is far longer than the time duration of the gas supplementing time period; for example, the preset time period may be 8 hours, and the air supplement period may have a time period of 0.25 hours.

Step 1021, if the sub-period is not coincident with the gas supplementing period, determining a gas leakage rate corresponding to the sampling time according to the gas pressure, the gas temperature and the atmospheric pressure acquired at the calculation starting time, and the gas pressure, the gas temperature and the atmospheric pressure acquired at the sampling time;

for example, if it is determined that the ending time of the sub-period is earlier than the starting time of the air supplement period, or the starting time of the sub-period is later than the ending time of the air supplement period, it may be determined that the sub-period and the air supplement period do not coincide with each other. In this case, the operation of supplying hydrogen does not affect the gas pressure in the sub-period, and the actually measured gas pressure value can be used for calculation. For example, the gas leakage rate at this sampling time can be calculated according to equation two:

where Δ V is the gas leakage (in m) per 24 hours corresponding to the sampling time in a given state³24h), the atmospheric pressure P0 is 101.3KPa (A) in the given state, the atmospheric absolute temperature T0 is 293K, the delta T is the preset time length, and V is the total inflation volume (m is the unit of m) in the air inflation period³) T0 is the absolute temperature, P, at a given atmospheric pressure₃The gas pressure (in KPa (G)) acquired at the start of the sub-period₃The gas temperature (in K), B, collected at the beginning of the sub-period₃Atmospheric pressure (in KPa (A)) acquired at the start of the sub-period₄The gas pressure (in KPa (G)) acquired at the end of the sub-period, T₄The gas temperature (in K), B, taken at the end of the sub-period₄The atmospheric pressure collected for the end time of the sub-period.

And 1022, if the sub-period coincides with the gas supplementing period, using a superposition result of the gas pressure acquired at the calculation starting time and the pressure correction increment value as an updated gas pressure, and determining a gas leakage rate corresponding to the sampling time according to the updated gas pressure, the gas temperature and the atmospheric pressure acquired at the calculation starting time, and the gas pressure, the gas temperature and the atmospheric pressure acquired at the sampling time.

For example, if it is determined that the time included in the sub-period and the time included in the air supplement period have an intersection, it may be determined that the sub-period and the air supplement period coincide with each other. The gas leakage rate at this sampling time can be calculated according to equation three:

wherein, the same parameters in the formula three and the formula one and the formula two have the same meanings, and are not repeated herein.

Generally speaking, when a maintainer detects that the pressure of hydrogen in a cooling system is reduced to about 290kpa (g), continuous gas supplementing operation is performed until the pressure of hydrogen in the cooling system is reduced to about 300kpa (g), gas supplementing is stopped, when a sub-period coincides with the gas supplementing period, the difference between the gas pressure added by hydrogen supplementation and the gas pressure acquired at the start time of the sub-period is large in value, and the accuracy of subsequent leakage rate calculation is seriously reduced.

Therefore, the method and the device can flexibly adjust the use of the gas pressure change caused by gas supplementing in the calculation process according to the time sequence relation between the gas supplementing time period and the sub-time period, so that the gas leakage rate corresponding to each sampling time more conforms to the actual leakage condition.

In one possible implementation, the method further includes:

and in the preset time period, if the gas leakage rate corresponding to the sampling moment exceeds a preset threshold value, executing prompt operation, wherein the prompt operation is used for prompting the sealing operation of the cooling system.

Fig. 2 is a schematic diagram illustrating a calculation result of a method for calculating a hydrogen real-time leakage rate of a generator according to an application example. In the leak rate calculation employed in the related art, a fixed calculation span takes 8 hours. As can be seen from the gas leakage rate calculation result obtained by adopting the method disclosed by the invention, the data shows better continuity. Wherein, the system running the method of the present disclosure found a significant increase in leak rate at about 20:00 on 14 days 10 months. And in 10 months and 15 days, 12:00 or so, the maintenance personnel immediately adopt glue injection operation, and then the leakage rate is immediately reduced to a normal value. At this stage, however, the result calculated and reported using a manual method is difficult to determine the leak rate rise since the rise amplitude is not significant.

Fig. 3 is a block diagram illustrating a generator hydrogen real-time leakage rate calculation device according to an exemplary embodiment. As shown in fig. 3, the apparatus includes:

the first determining module 30 is configured to determine an air supply time period within a preset time period, where the air supply time period is a time period for supplying hydrogen to a cooling system of a hydrogen cooling generator set;

a third determining module 32, configured to perform the following operations for each sampling time in the preset time period, to obtain a gas leakage rate corresponding to each sampling time:

taking the sampling time before the preset time length of the sampling time as a calculation starting time, and taking the time period between the calculation starting time and the sampling time as a sub-time period corresponding to the sampling time, wherein the preset time length is far longer than the time length of the air supply time period;

if the sub-time interval is not coincident with the gas supplementing time interval, determining the gas leakage rate corresponding to the sampling time according to the gas pressure, the gas temperature and the atmospheric pressure acquired at the initial calculation time, and the gas pressure, the gas temperature and the atmospheric pressure acquired at the sampling time;

and if the sub-period coincides with the gas supplementing period, taking a superposition result of the gas pressure acquired at the calculation starting time and the pressure correction added value as an updated gas pressure, and determining the gas leakage rate corresponding to the sampling time according to the updated gas pressure, the gas temperature and the atmospheric pressure acquired at the calculation starting time, and the gas pressure, the gas temperature and the atmospheric pressure acquired at the sampling time.

In one possible implementation manner, the first determining module includes:

the first determining submodule is used for taking the earliest sampling moment in a plurality of continuous sampling moments as the starting moment of the gas supplementing period if the gas pressure intensity acquired at the continuous sampling moments is sequentially and continuously increased in the preset period;

and the second determining submodule is used for taking the sampling time as the ending time of the gas supplementing time interval if the gas pressure acquired at a certain sampling time after the starting time is lower than the gas pressure acquired at a sampling time before the sampling time in the preset time interval.

In one possible implementation manner, the second determining module includes:

and the third determining submodule is used for determining the pressure correction increase value according to the gas pressure, the gas temperature and the atmospheric pressure acquired at the sampling moment immediately before the air supplementing time period and the gas pressure, the gas temperature and the atmospheric pressure acquired at the sampling moment immediately after the air supplementing time period.
