When the wind power system is connected to the grid on a large scale, it will face very complicated working conditions. In order to guarantee the healthy grid operation of the new energy system, during the product iteration of "R&D-Production-Testing" in the industry, the R&D and testing engineers have to repeatedly modify the parameters of the controllers and the parameters of the filters in order to carry out the testing of the wind turbines under a series of different working conditions. Based on the semi-physical simulation to support the construction of any topology model and the characteristics of a high degree of accuracy, the use of hardware-in-the-loop for the testing of wind turbines to be connected to the grid has already become a mainstream trend nowadays.
Compared to traditional testing methods, the introduction of Hardware-in-the-Loop (HIL) platform of ModelingTech has increased our testing efficiency by approximately 10 times. For experiments that require repeated testing to obtain data, the hil simulation platform can provide abundant test data quickly.
