[0041] The following will describe the specific implementation of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and does not limit the present disclosure.

[0042] In view of the problems mentioned in the background art, the embodiments of the present disclosure provide an offshore wind farm simulation system, method and electronic device. The simulation control instructions are output through the simulation control system of the object to be simulated. According to the simulation control instructions, the mathematical simulation model of the object to be simulated uses the electrical power flow algorithm to generate the real-time simulation data of the object to be simulated. Then, the real-time calculation engine processes the real-time simulation data and sends the processed real-time three-dimensional data to the rendering module. Finally, the rendering module can perform image rendering according to the three-dimensional simulation model and the real-time three-dimensional simulation data to obtain the corresponding real-time three-dimensional effect of the object to be simulated. It can be seen that in the embodiments of the present disclosure, not only the 3D modeling display of the object to be simulated is performed, but also the simulation control system and the mechanism mathematical simulation model of the object to be simulated are modeled. The internal control algorithm logic support of the object to be simulated is introduced, and the operation behaviors that may exist in the real operation environment of the object to be simulated and the state change scenarios occurring with the operation behaviors are highly restored, and the on-site operation and maintenance environment of the offshore wind farm is restored, thereby improving the simulation training effect.

[0043] The embodiments of the present disclosure show an offshore wind farm simulation system, which includes a mathematical simulation model of the object to be simulated, a three-dimensional simulation model of the object to be simulated, a simulation control system of the object to be simulated, a real-time calculation engine, and a rendering module. Among them, the object to be simulated includes an offshore substation, an onshore substation, and a wind turbine cluster.

[0044] In the embodiments of the present disclosure, as shown in Figure 1 the offshore wind farm simulation system may include an offshore substation mathematical simulation model 111, an offshore substation three-dimensional simulation model 112, an offshore substation simulation control system 113, an onshore substation mathematical simulation model 121, an onshore substation three-dimensional simulation model 122, an onshore substation simulation control system 123, a wind turbine cluster mathematical simulation model 131, a wind turbine cluster three-dimensional simulation model 132, and a wind turbine cluster simulation control system 133. Among them, the wind turbine cluster is composed of multiple wind turbines. In addition, the offshore wind farm simulation system may further include a real-time calculation engine 140 and a rendering module 150.

[0045] In some embodiments, the real-time calculation engine may be an RTSRV real-time calculation engine, and the rendering module includes a U3D calculation engine.

[0046] Exemplarily, when using an offshore wind farm simulation system, such as during training, according to the training requirements, the simulation control system corresponding to the offshore substation can be manipulated to output simulation control instructions. Then, the mathematical simulation model corresponding to the offshore substation can generate real-time simulation data of the offshore substation using the electrical power flow algorithm based on the simulation control instructions. Next, the real-time calculation engine can process the real-time simulation data and send the processed real-time three-dimensional data to the rendering module. Finally, the rendering module can perform image rendering based on the three-dimensional simulation model and the real-time three-dimensional simulation data to obtain the real-time three-dimensional effect corresponding to the offshore substation. For example, the operating states and abnormal changes of each platform device in the offshore substation can be displayed in real time on the three-dimensional offshore substation model, thereby realizing the simulated operation and abnormal linkage of each device on the offshore operation platform of the offshore substation.

[0047] In addition, in order to further restore the actual operation and maintenance environment of the offshore wind turbine nacelle and achieve high-precision simulation of the offshore wind turbine nacelle, in some embodiments, the offshore wind farm simulation system may further include:

[0048] A real wind turbine nacelle equipment unit and a corresponding physical control unit. The physical control unit corresponding to the real wind turbine nacelle equipment unit is connected to the simulation control system of the wind turbine nacelle through the Modbus protocol; the simulation control system of the wind turbine nacelle is further configured to send control data to the physical control unit corresponding to the real wind turbine nacelle equipment unit; the physical control unit corresponding to the real wind turbine nacelle equipment is configured to control the state of the real wind turbine nacelle equipment unit according to the control data; and a simulation database for obtaining the real-time state data of the real wind turbine nacelle equipment unit.

[0049] In the embodiments of the present disclosure, a real wind turbine nacelle equipment unit can be set, and the physical control unit corresponding to the real wind turbine nacelle equipment unit can be connected to the simulation control system of the wind turbine nacelle through the Modbus protocol. In this way, the simulation control system of the wind turbine nacelle can send control data to the physical control unit corresponding to the real wind turbine nacelle equipment unit, so that the physical control unit corresponding to the real wind turbine nacelle equipment can control the state of the real wind turbine nacelle equipment unit according to the control data. Moreover, after controlling the real wind turbine nacelle equipment unit to work, the physical control unit corresponding to the real wind turbine nacelle equipment can send the state data of the real wind turbine nacelle equipment unit to the simulation database, and the data is fed back to the rendering module through the simulation database for rendering and display, so as to realize the two-way linkage between software simulation and the physical actions of the wind turbine nacelle and improve the simulation effect.

[0050] In the embodiments of the present disclosure, by adopting a method of using some physical devices and some modeled devices, a simulation system for an offshore wind farm can be freely designed according to requirements or conditions such as equipment cost and simulation complexity. This not only retains the controllability of the hardware devices of the local control unit of the fan nacelle but also ensures the integrity of the entire fan and the wind farm system, further improving the simulation effect while enhancing the simulation convenience.

[0051] In some embodiments, the simulation control system of the object to be simulated is obtained by performing a 1:1 simulation of the real PLC logic of the corresponding object to be simulated through graphical modeling technology.

[0052] In the embodiments of the present disclosure, graphical modeling technology can be used to adopt the real PLC logic of the object to be simulated to achieve a 1:1 simulation of the entire range of the control system of the object to be simulated.

[0053] For example, for the human-machine interface control system of a fan, using graphical modeling technology and adopting the real PLC logic of a certain type of offshore wind turbine, a 1:1 simulation of the entire range of the control systems of each subsystem of the offshore wind turbine is achieved, ensuring the integrity and reliability of the fan model. All faults are compared and tested one by one on the real unit, and the accuracy rate reaches 95% or above.

[0054] In some embodiments, the three-dimensional simulation model of the object to be simulated is obtained by 3D modeling technology according to the real structure diagram of the corresponding object to be simulated through 1:1 simulation modeling.

[0055] In the embodiments of the present disclosure, 3D modeling technology can be used to perform 1:1 high-precision modeling of equipment with reference to the real structure diagrams of simulation objects (such as offshore substations, onshore substations, fans, etc.).

[0056] For example, for an offshore wind turbine, 3D modeling technology can be used to perform 1:1 high-precision modeling of equipment with reference to the real structure diagram of the unit, achieving L4-level simulation of the equipment (with an error in centimeters). The physical models of the fan nacelle, tower base, and each layer are highly realistic, and the dynamic changes match the site one by one, being closely coupled with the above simulation control system.

[0057] In some embodiments, the mathematical simulation model corresponding to the fan cluster is a wind farm equivalent model established based on the location of the wind farm, the wake effect of the fan, the wind delay effect, the wind speed model, the mathematical simulation models corresponding to each fan, and the doubly fed induction motor model.

[0058] In the embodiments of the present disclosure, on the basis of considering the location of the wind farm and the wake effect of the fan, the wind delay effect is taken into account and combined with the wind speed model, the mathematical model corresponding to the fan, and the doubly fed induction motor model to establish a relatively accurate and engineering-practical wind farm equivalent model.

[0059] In some embodiments, the mathematical simulation model corresponding to a single wind turbine is obtained by modeling a maritime meteorological model, a wind farm model, and a wind turbine model. The wind turbine model includes a PLC safety automatic device system, a pitch system, a gearbox and transmission system, a hydraulic control system, a safety chain system, a lubricating oil system, and a wind turbine braking system.

[0061] In some embodiments, the mathematical simulation model corresponding to an offshore substation is obtained by modeling the primary system and secondary system of the offshore substation through power simulation modeling technology; the mathematical simulation model corresponding to an onshore substation is obtained by modeling the primary system and secondary system of the onshore substation through power simulation modeling technology.

[0062] In the embodiments of the present disclosure, the substation model can be built based on the primary system and secondary system of the offshore substation through graphical power simulation modeling technology, and the substation model can also be built based on the primary system and secondary system of the onshore substation through graphical power simulation modeling technology.

[0064] The rendering module is configured to perform image rendering based on the real-time status data to obtain the real-time status effect corresponding to the object to be simulated.

[0065] In the embodiments of the present disclosure, in addition to obtaining real-time three-dimensional simulation data, the real-time calculation engine can also obtain real-time status data by processing real-time simulation data. By sending the real-time status data to the rendering module, the rendering module can perform image rendering based on the real-time status data to obtain the real-time status effect corresponding to the object to be simulated. For example, displaying various state changes, lighting changes, statistical data changes, etc. of the simulation object.

[0066] In some embodiments, the offshore wind farm simulation system further includes:

[0069] For example, the five-prevention invoicing process of the offshore substation, the remote control and telemetry process of the monitoring system of the offshore substation, and the fault warning and alarm monitoring process of the offshore substation can be simulated according to the mathematical simulation model of the offshore substation, the three-dimensional simulation model of the offshore substation, the simulation control system of the offshore substation, the real-time calculation engine, and the rendering module.
