[0028] Figure 2 A schematic diagram of another flywheel operation risk monitoring system provided in Embodiment 1 of the present invention.
[0029] Reference Figure 1 and Figure 2The flywheel operation risk monitoring system includes a flywheel entity 1, an intelligent decision-making module 2 and a flywheel digital twin 3 which are communicatively connected to each other; a sensor component 4 is arranged on the flywheel entity 1.
[0030] The sensor component 4 is used to detect the initial operating data of the flywheel entity 1 at startup and the real-time operating data during operation, and send the initial operating data to the flywheel digital twin 3 and send the real-time operating data to the intelligent decision-making module 2.
[0031] Here, the sensor assembly includes a temperature sensor for collecting temperature data at various locations on the flywheel; a Hall sensor or a resolver sensor for collecting flywheel speed data; an electromagnetic bearing displacement sensor for collecting axial and radial displacements of the electromagnetic bearing in the flywheel, thereby determining the vibration data of the flywheel; an electromagnetic field measuring instrument for collecting electromagnetic field data of the flywheel; and a rotor displacement sensor for collecting rotor position data in the flywheel.
[0032] The initial operation data includes initial vacuum degree data, initial temperature data, initial rotation speed data, initial vibration data, initial electromagnetic field data and initial rotor position data of the flywheel entity.
[0033] The real-time operation data includes the operation vacuum data, operation temperature data, operation speed data, operation vibration data, operation electromagnetic field data and operation rotor position data of the flywheel entity.
[0034] The flywheel digital twin 3 is used to simulate the operating status of the flywheel entity 1 throughout its life cycle based on the initial operating data, and send the simulated operating data obtained by the simulation to the intelligent decision-making module 2.
[0035] Here, the intelligent decision-making module includes a simulation operation result database for storing simulation operation data sent after the flywheel digital twin performs a full life cycle simulation. In one embodiment, the flywheel digital twin is obtained by:
[0036] First, an initial 3D model of the flywheel entity is constructed.
[0037] Then, the initial operating data of the flywheel entity is used as input, and the real-time operating data of the flywheel entity during operation is used as output. The initial three-dimensional model is trained until the preset training conditions are met to obtain a trained flywheel digital twin.
[0038] Here, the steps to construct the initial 3D model of the flywheel entity include:
[0039] An initial 3D model of the flywheel is constructed based on the mechanical, electrical, hydraulic, control, and electromagnetic properties of the flywheel entity.
[0040] The intelligent decision-making module 2 is used to predict the operation risk of the flywheel entity 1 according to the real-time operation data of the flywheel entity 1 and the simulated operation data of its corresponding life cycle, and adjust the operation control of the flywheel entity 1 based on the operation risk.
[0041] Here, after receiving the real-time operation data sent by the flywheel entity, the intelligent decision-making module extracts the simulation operation data in the simulation operation result database, and compares the real-time operation data with the simulation operation data to predict the operation risk of the flywheel entity.
[0042] Furthermore, the intelligent decision-making module is also used to:
[0043] Based on the operational risk of the flywheel entity, the target emergency measures corresponding to the operational risk are determined.
[0044] The flywheel entity is operated and controlled according to the target emergency measures so that the real-time operation data of the flywheel entity is consistent with the simulation operation data of its corresponding life cycle.
[0045] Specifically, when the operating vacuum data is inconsistent with the simulated vacuum data, the intelligent decision module controls the vacuum pump of the flywheel entity to turn on or off, so that the operating vacuum data is consistent with the simulated vacuum data. When the operating temperature data is inconsistent with the simulated temperature data, the intelligent decision module controls the water cooling device of the flywheel entity to increase or decrease the water flow or the air cooling device to increase or decrease the wind speed, so that the operating temperature data is consistent with the simulated temperature data. When the operating speed data is inconsistent with the simulated speed data, the intelligent decision module controls the flywheel entity motor to increase or decrease the speed of the flywheel entity, so that the operating speed data is consistent with the simulated speed data. When the operating vibration data is inconsistent with the simulated vibration data, the intelligent decision module controls the electromagnetic bearing of the flywheel entity to make the operating vibration data consistent with the simulated vibration data. When the operating rotor position data is inconsistent with the simulated rotor position data, the intelligent decision control module generates an electromagnetic force equivalent to the rotor weight by adjusting the current of the control electromagnet winding, so that the rotor position data is consistent with the simulated rotor position data.
[0046] In one embodiment, the sensor assembly is further used to detect the ambient temperature information and ambient air pressure information of the flywheel entity when the flywheel entity is in a stationary state.
[0047] Here, the sensor assembly also includes an ambient temperature sensor and an ambient air pressure gauge. The ambient temperature sensor is used to measure the temperature data of the environment where the flywheel entity is located; the ambient air pressure gauge is used to measure the air pressure data of the environment where the flywheel entity is located.
[0048] The flywheel digital twin is also used to simulate the material weathering state and oxidation state of the flywheel entity based on ambient temperature information, ambient air pressure information, and material properties of the flywheel entity.
[0049] Here, the flywheel digital twin can simulate the material weathering state and oxidation state of the flywheel entity based on the pre-set material properties of the flywheel entity and the temperature data and air pressure data of the environment in which the flywheel entity is located.
[0050] In one embodiment, the system further comprises a display module, the display module being communicatively connected to the flywheel digital twin;
[0051] The display module is used to display the digital twin of the flywheel when the flywheel entity is stationary.
[0052] Here, when the flywheel entity is stationary, the display module will display the flywheel digital twin to simulate the weathering state and oxidation state of the flywheel entity material, so as to facilitate the staff to maintain and service the flywheel entity according to the simulated weathering and oxidation states.
[0053] The display module is also used to display the simulation process of the flywheel digital twin in real time when the flywheel entity is running.
[0054] Here, when the flywheel entity is running, the display module will display the full-cycle simulation process of the flywheel digital twin in real time, showing the operating status of the flywheel entity to the staff more intuitively.
[0055] The embodiment of the present invention provides a flywheel operation risk monitoring system, the system includes: a flywheel entity, an intelligent decision module and a flywheel digital twin that are connected to each other in communication; a sensor component is arranged on the flywheel entity; the sensor component is used to detect the initial operation data of the flywheel entity at startup and the real-time operation data during operation, and send the initial operation data to the flywheel digital twin, and send the real-time operation data to the intelligent decision module; the flywheel digital twin is used to simulate the operation state of the flywheel entity throughout the life cycle according to the initial operation data, and send the simulated operation data obtained by the simulation to the intelligent decision module; the intelligent decision module is used to predict the operation risk of the flywheel entity according to the real-time operation data of the flywheel entity and the simulated operation data of its corresponding life cycle, and adjust the operation control of the flywheel entity based on the operation risk.

[0060] The core entities of the flywheel digital twin include flywheel modeling, simulation, data access and interaction, cloud computing, machine learning, and big data.
[0061] Here, the core entity of the flywheel digital twin is supported by general technology to realize functions such as model construction and fusion, data integration, simulation analysis, and system expansion. Since the flywheel digital twin needs to accurately express the state of the flywheel entity, it is critical to establish a suitable model. The Modelica modeling language can be used to establish the initial three-dimensional model of the flywheel entity according to the mechanical, electrical, hydraulic, control, and electromagnetic performance of the flywheel entity. Because the main function of the flywheel digital twin is to predict the operating status of the equipment during its life cycle, and the design is only for the flywheel entity, which belongs to the unit-level simulation, the ANSYS software can be used to simulate and calculate the mechanical structure and electromagnetic field distribution of the flywheel. Since the simulation of the operating status of the life cycle requires real-time processing of information, the timeliness of the simulation calculation is required to be high at one time, and cloud computing can also be used to provide sufficient computing power for simulation calculation. With ANSYS system software as the core, building a suitable model can more realistically reflect the actual operating status of the flywheel entity. Combined with cloud computing, the flywheel operating status can be simulated and predicted in real time. The initial three-dimensional model is trained through machine learning and continuously corrected until the preset training conditions are met, and a trained flywheel digital twin is obtained, and feedback control is performed.
