[0037] In the process of adopting technical solutions to address the technical problems in the background technology, the following technical problem two often arises: how to determine whether to activate the black start system. The conventional solution to this technical problem two is generally to activate the black start system after confirming a fault based on monitored voltage. However, this conventional solution still has the following problem: activating the black start system after a fault occurs results in a longer power outage time and a poor user experience for the power grid.

[0038] Considering the problems with the conventional solutions mentioned above, and addressing the second technical problem, by collaborating with AI researchers from universities and leveraging their existing AI algorithms, the following solution can be adopted: Optionally, the above-mentioned control device can be further configured to: The first step involves obtaining a sequence of current grid parameter information in response to the detection of voltage anomaly information corresponding to the aforementioned grid devices. This voltage anomaly information can be information characterizing voltage anomalies in the grid devices. It may include, but is not limited to, voltage anomaly monitoring values. The voltage detection values ​​can be the abnormal voltage values ​​detected.

The parameter types can be, but are not limited to, one of the following: grid current, grid frequency, and grid power. In practice, the executing entity can obtain the sequence of current grid parameter information from a database via wired or wireless connection.

[0039] The second step involves inputting the aforementioned current power grid parameter information sequence into a pre-trained first power grid fault prediction information generation model to obtain the first power grid fault prediction information. This first power grid fault prediction information generation model can be a long short-term memory neural network that takes the current power grid parameter information sequence as input and outputs the first power grid fault prediction information. The first power grid fault prediction information can characterize the probability and type of a power grid fault occurring at a future time. This information may include, but is not limited to, the first power grid fault type and the first power grid fault probability value. The first power grid fault type can be, but is not limited to, one of the following: voltage sag or voltage surge. The first power grid fault probability value represents the probability of a power grid fault occurring.

[0040] The third step is to obtain the current environmental information and equipment monitoring information of the aforementioned power grid devices.

The second power grid fault type can include, but is not limited to, cable damage and transformer damage. The second power grid fault probability value can be the probability of a power grid fault occurring. It should be noted that the interval between the time point of occurrence of the power grid fault predicted by the first and second power grid fault prediction information and the current time point is the time required to start the black start system.

[0042] Fifth, based on the aforementioned first power grid fault prediction information, power grid fault prediction information is generated. In practice, firstly, the product of a preset first fault type weight value corresponding to the first power grid fault type included in the aforementioned first power grid fault prediction information and a first power grid fault probability value can be determined as the first fault probability value. Secondly, the product of a preset second fault type weight value corresponding to the second power grid fault type included in the aforementioned second power grid fault prediction information and a second power grid fault probability value can be determined as the second fault probability value. Then, the sum of the first fault probability value and the second fault probability value is determined as the fault probability value. Finally, the aforementioned fault probability value, the first power grid fault type, and the second power grid fault type are determined as the power grid fault prediction information.

[0043] Step 6: In response to determining that the aforementioned power grid fault prediction information meets preset fault type conditions, control the aforementioned pure hydrogen gas turbine unit to perform a pre-start operation. The preset fault type conditions may be that the fault probability value included in the power grid fault prediction information is greater than a preset fault probability, and the first power grid fault type and / or the second power grid fault type is a preset black-start type. The preset fault probability may be a pre-set probability characterizing the probability that a power grid fault will occur. The preset black-start type may be a pre-set condition characterizing the corresponding power grid fault type requiring the activation of the black-start system. The pre-start operation may be an operation that puts the pure hydrogen gas turbine into a standby state.

[0044] Step 7: In response to the current time meeting the preset fault prediction duration condition and the detection of grid confirmed fault information, the preset grid outage information is determined as the grid outage information corresponding to the aforementioned grid device. The preset fault prediction duration condition can be that the interval between the current time and the time point at which the current grid parameter information sequence is obtained is greater than or equal to the preset fault prediction duration. The preset fault prediction duration can be a pre-set duration from the predicted grid fault to the occurrence of the fault. For example, the preset fault prediction duration can be 1 minute. The grid confirmed fault information can indicate that a fault has occurred in the grid system. For example, the grid confirmed fault information can be 1 minute. The preset grid outage information can be pre-set information indicating a grid system outage.

[0045] Step 8: In response to the current time meeting the above-mentioned preset fault prediction duration condition and the absence of the above-mentioned grid confirmed fault information, control the above-mentioned pure hydrogen gas turbine unit to perform the above-mentioned pre-start operation to shut down.

[0046] The above-described technical solution and related content, as an inventive point of this disclosure, solve the technical problem of "poor user experience in the power grid." Factors leading to a poor user experience in the power grid often include: restarting the black-start system after a fault occurs, resulting in a prolonged power outage and a poor user experience. Solving these factors can improve the user experience. To achieve this, the black-start system of this disclosure, applicable to pure hydrogen gas turbine units, monitors voltage fluctuations in a timely manner, considers the influence of the external environment and the operating status of the equipment, anticipates the possibility of power grid faults, and preemptively puts the black-start system into a standby state based on the prediction results. Therefore, when the black-start system needs to be started, the black-start operation time can be shortened, power supply can be restored as quickly as possible, thereby improving the user experience.

[0047] Optionally, the aforementioned black-start system may further include an oil heating device. This oil heating device can be a device for heating lubricating oil.

As an embodiment, the electrical components included in the oil heating device may be electrically connected to the output terminal of the inverter assembly. The control device 105 can be configured to control the lubricating oil heating device to perform a lubricating oil heating operation before the pure hydrogen gas turbine unit is put into operation. The lubricating oil heating operation can be an operation to heat the lubricating oil.

[0048] In the process of adopting technical solutions to address the technical problems in the background art, the following technical problem three often arises: how to control the temperature of the lubricating oil. The conventional solution to this technical problem three is generally to pre-set the temperature of the lubricating oil. However, this conventional solution still has the following problems: different operating environments and different states of lubricating oil in pure hydrogen gas turbine units lead to different lubrication effects at the same temperature. Furthermore, since the fuel in a pure hydrogen gas turbine unit is pure hydrogen, when hydrogen diffuses onto the bearings, the lubricating oil temperature also affects the hydrogen embrittlement phenomenon of the bearings, resulting in a shorter bearing life.

[0049] Considering the problems with the conventional solutions mentioned above, and addressing the third technical problem, by collaborating with AI researchers from universities and leveraging their existing AI algorithms, the following solution can be adopted: Optionally, the aforementioned lubricating oil heating device may further include a hydrogen concentration detection sensor assembly, a lubricating oil condition detection assembly, and a temperature detection sensor assembly.

In practice, the executing entity can obtain the environmental information and gas turbine power information corresponding to the aforementioned pure hydrogen gas turbine unit from a database via wired or wireless connection.

[0051] The second step involves detecting the current hydrogen concentration using the aforementioned hydrogen concentration detection sensor assembly. This current hydrogen concentration characterizes the concentration of hydrogen gas present in the lubricating oil.

[0052] The third step involves detecting the current bearing temperature using the aforementioned temperature detection sensor assembly. This current bearing temperature can be the temperature of the bearings included in the aforementioned pure hydrogen gas turbine unit.

[0053] The fourth step is to detect the current water content of the lubricating oil using the aforementioned lubricating oil condition detection component. The current water content of the lubricating oil can refer to the current water content within the lubricating oil.

[0054] The fifth step involves generating the basic lubricating oil temperature based on the aforementioned environmental and gas turbine power information.

In practice, the ambient temperature and humidity (as per the aforementioned environmental information) and the gas turbine power (as per the aforementioned gas turbine power information) can be input into a preset basic lubricating oil temperature generation model to obtain the basic lubricating oil temperature. This preset basic lubricating oil temperature generation model can be a linear function that takes ambient temperature, ambient humidity, and gas turbine power as inputs and outputs the basic lubricating oil temperature.

[0055] Step 6: Based on the current hydrogen concentration and the preset first temperature influence factor, generate the first adjustment temperature. The preset first temperature influence factor characterizes the effect of unit hydrogen concentration on lubricating oil temperature. In practice, the product of the current hydrogen concentration and the preset first temperature influence factor can be used to determine the first adjustment temperature.

[0056] Step 7: Based on the current bearing temperature and the preset second temperature influence factor, generate the second adjustment temperature. The preset second temperature influence factor characterizes the effect of bearing temperature on lubricating oil temperature. In practice, the difference between the current bearing temperature and the preset bearing temperature can be defined as the bearing temperature difference. The preset bearing temperature can be a pre-set temperature representing the normal operation of the pure hydrogen gas turbine unit without wear. Then, the product of the bearing temperature difference and the preset second temperature influence factor is determined as the second adjustment temperature.

[0057] Step 8: Based on the current lubricating oil water content and the preset third temperature influence factor, generate the third adjustment temperature.

[0061] The above-described technical solution and related content, as an inventive point of this disclosure, solve the technical problem of "short bearing life". Factors leading to short bearing life often include: different operating environments of pure hydrogen gas turbine units, different states of lubricating oil, resulting in different lubrication effects of lubricating oil at the same temperature; and the fact that pure hydrogen gas turbine units use pure hydrogen gas as fuel, when hydrogen diffuses onto the bearing, the lubricating oil temperature also affects the hydrogen embrittlement phenomenon of the bearing, thus causing a short bearing life. Solving these factors can improve bearing life. To achieve this effect, the black-start system of this disclosure, applicable to pure hydrogen gas turbine units, employs a lubricating oil heating device. When determining the lubricating oil temperature, it not only considers the operating environment and the power of the pure hydrogen gas turbine unit, but also determines a more accurate lubricating oil temperature by real-time monitoring of the aging state of the lubricating oil and the condition of the bearing. Simultaneously, it considers the influence of lubricating oil temperature on bearing hydrogen embrittlement through hydrogen concentration, thereby reducing bearing hydrogen embrittlement while ensuring lubrication effect, thus improving bearing life.
