In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

In the description of the present application, it is also to be noted that, unless otherwise explicitly specified or limited, the terms "disposed" and "connected" are to be interpreted broadly, e.g., as being either fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

With the development of wind generating sets (referred to as wind generating sets for short), in order to more conveniently realize the control of the wind generating sets, the prior art proposes a control architecture of the wind generating sets, as shown in fig. 1. And a sensing module and an actuating mechanism on the wind turbine are connected with the wind generating set controller through an IO module/can bus. An environment process, a generator process, a fan control process, a pitch process, a converter process and the like are installed in the wind generating set controller. The processes can acquire data transmitted by the sensing module and the actuating mechanism through the IO module/can bus. The fan control process and other processes are all provided with data interaction. Other processes also have data interactions with each other.

After a great deal of practical conclusion of the inventor, the architecture shown in fig. 1 is found to be complicated in program architecture redundancy because processes are interactively coupled with each other in data; the time sequence relation among all modules needs to be considered in the design process; later-stage requirement change can cause low iteration efficiency of each sub-module; adding or deleting sub-modules requires re-breaking the original architecture and re-designing.

Taking a possible data cross-coupling scenario as an example, when new sensing module data is received, each component needs to generate corresponding control parameters, referring to fig. 1, the control parameters generated by the generator process not only depend on the sensing module data, but also have a relationship with the pitch variation, the converter and the like, when the current corresponding generator parameters are generated, it is necessary to wait for the pitch variation process and the converter process to generate the current corresponding parameters, and the current corresponding parameters generated by the pitch variation process and the converter process need to depend on parameters generated by other processes, so that there is a problem of data cross-coupling.

The embodiment of the application provides electronic equipment, and the electronic equipment can be a control system of a wind generating set. Referring to fig. 2, fig. 2 is a schematic structural diagram of an electronic device. The electronic device comprises a processor 10, a memory 11, a bus 12. The processor 10 and the memory 11 are connected by a bus 12, and the processor 10 is configured to execute an executable module, such as a computer program, stored in the memory 11.

The processor 10 may be an integrated circuit chip having signal processing capabilities. In implementation, the steps of the wind turbine generator system control method may be implemented by integrated logic circuits of hardware in the processor 10 or instructions in the form of software. The Processor 10 may be a general-purpose Processor, and includes a Central Processing Unit (CPU), a Network Processor (NP), and the like; the device can also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, or a discrete hardware component.

The bus 12 may be an ISA (Industry Standard architecture) bus, a PCI (peripheral component interconnect) bus, an EISA (extended Industry Standard architecture) bus, or the like. Only one bi-directional arrow is shown in fig. 2, but this does not indicate only one bus 12 or one type of bus 12.

The memory 11 is used for storing programs, such as programs corresponding to the wind generating set control devices. The wind turbine generator system control device comprises at least one software function module which can be stored in the memory 11 in the form of software or firmware (firmware) or is fixed in an Operating System (OS) of the electronic device. The processor 10 executes the program to realize the wind generating set control method after receiving the execution instruction.

Wherein the first buffer space and the second buffer space may be disposed in the memory 11.

The components shown in fig. 2 may be implemented in hardware, software, or a combination thereof.

and S101, acquiring sensing data and historical fan parameters.

The historical fan parameters are generated by the processor 10 in the previous period, the historical fan parameters include historical parameters of units associated with the first unit, the sensing data is data transmitted by sensing modules associated with the first unit, and the first unit is any one of execution mechanisms in the fan.

Specifically, the fan parameters of the unit associated with the first unit generated in the last period and the data transmitted by the sensing module associated with the first unit are acquired.

S102, generating a first current parameter according to the sensing data and the historical parameters of the associated units.

Specifically, a first current parameter is generated according to the historical parameters of the associated cell generated in the last period and the currently received sensing data. Because of the continuity and the time delay of the fan operation, it is feasible to generate the first parameter by using the historical parameter generated in the above one period as a reference. In the process of generating the first current parameter, other parameters generated in the period may not be referred to.

S103, the first current parameter is transmitted to the first unit, so that the first unit operates according to the first current parameter.

In summary, in the control method of the wind turbine generator system provided in the embodiment of the present application, the sensing data and the historical parameters of the historical wind turbine generator are obtained, the first current parameter is generated according to the sensing data and the historical parameters of the associated units, and the first current parameter is transmitted to the first unit, so that the first unit operates according to the first current parameter. In the process of generating the first current parameter, other parameters generated in the period are not referred to, so that the problem of data cross coupling is avoided, the program architecture can be simplified, and design obstacles are reduced.

On the basis of fig. 4, for the history parameters of the first unit and the unit associated with the first unit in S101, the embodiments of the present application propose several possibilities:

first, the first unit may be a generator unit, and the historical wind turbine parameters associated with the generator unit include wind turbine control parameters, pitch parameters, and converter parameters.

Second, the first unit may be a pitch unit, and the historical fan parameters associated with the pitch unit include fan control parameters.

Third, the first unit may be a converter unit and the historical fan parameters associated with the converter unit include fan control parameters and generator parameters.

Fourth, the first unit may be a wind turbine control unit, and the historical wind turbine parameters associated with the wind turbine control unit include generator parameters, environmental parameters, pitch parameters, and converter parameters.

Fifth, the first unit may be an environmental unit, and the historical fan parameters associated with the environmental unit include fan control parameters, generator parameters, and converter parameters.

The first unit is not specifically limited, and the first unit may be any other actuator on the fan.

On the basis of fig. 4, a possible implementation manner is further provided in the embodiment of the present application for setting the historical wind turbine parameters, please refer to fig. 5, where the wind turbine generator system control method further includes:

and S104, taking the first current parameter as a new historical fan parameter.

Specifically, referring to fig. 3, after each process generates a corresponding first current parameter, the generated first current parameter is stored in the second cache space. And after all the processes store the corresponding parameters into the second cache space, updating the data in the second cache space into the first cache space, so that the first current parameter is used as a new historical fan parameter.

On the basis of fig. 5, for the content in S101, the embodiment of the present application further provides a possible implementation manner, please refer to fig. 6, where S101 includes:

s101-1, periodically acquiring sensing data and historical fan parameters.

Referring to fig. 7, the sensing data and the historical fan parameters are acquired every period T.

For example, acquiring sensing data and historical fan parameters at the nth time at a time ta; outputting the generated first current parameter at the time tb; acquiring sensing data and historical fan parameters for the (n + 1) th time at the time of tc. And the time ta and the time tc are separated by a time equal to the period T.

In one possible implementation, the period T may take a value of 0.05 seconds. And acquiring sensing data and historical fan parameters every 0.05 second. That is, when the current parameter is generated, the historical data before 0.05 second is referred to, and the data generated by other processes in the period is not referred to. Because of the delay of data transmission and the continuity of operation of each actuator, when the period value is 0.05 seconds, the first current parameter generated is most beneficial to the current fan operation.
