The hardware-in-the-loop test platform comprises a real-time parallel multi-processor platform which is configured to operate a multi-thread real-time operating system on the real-time parallel multi-processor platform so as to perform real-time simulation on a virtual model of the wind generating set and test the performance of a physical system of the wind generating set based on the virtual model; and the communication module is connected between the real-time parallel multi-processor platform and the physical system, and the physical system and the real-time parallel multi-processor platform communicate with each other through the communication module.

Description

technical field [0001] The present disclosure relates to the field of wind power generation, in particular to a hardware-in-the-loop test platform, a pitch-in-the-loop test system and a test system for a wind power generating set. Background technique [0002] With the increasing demand for energy by human beings, the wind power industry has developed rapidly by virtue of the attributes of wind energy as a clean energy, but at the same time there are many problems, such as the poor stability and low availability of wind turbines, due to human operation errors. Downtime and loss of power generation, the large number of configurations of wind turbines leads to insufficient verification of new equipment, which increases the failure rate and so on. The occurrence of the above-mentioned faults leads to higher and higher operation and maintenance costs of wind turbines, causing significant economic losses to wind power equipment manufacturers and wind power developers.

Problems solved by technology

For the simulation under the Windows system, because the Windows system is a non-real-time operating system, it often encounters the problem that the application program does not respond, or the hardware resources are occupied by other tasks, and the tasks cannot be executed immediately, which leads to some signal acquisition or control signals. Delay, it is difficult to achieve stable real-time closed-loop simulation

It is difficult to consider the nonlinearity of blades of large-scale wind turbines and the flexibility of the drive train in the simulation model of wind turbines established by Bladed software, and it is impossible to consider many factors such as generator flexibility, main bearing nonlinearity, and magnetic pull for direct-drive wind turbines. Effects on machine stability and load

Usually, the hardware-in-the-loop test module configured by the Bladed software itself is used to call the Ethernet network port of the computer in the Windows system to realize the communication between the computing module and the communication PLC. Poor performance and flexibility, unable to meet the needs of multi-channel testing

In addition, for simulation models with increased degrees of freedom or modes, the solution process of Bladed software tends to diverge and the solution accuracy is low

It can be seen that there are many deficiencies in the hardware-in-the-loop test using the GH Bladed software based on the Windows system
