Description

Technical Field

[0001] The present application relates to the field of synchronous speed simulation system, and in particular to a synchronous speed adjustment method and system for a dual-platform joint simulation system of a wind turbine generator set. Background Art

[0002] Detailed simulation of wind turbines often involves the integration of multiple disciplines. Currently, each specialized simulation platform can only support detailed simulation of one or a few specialized areas, with limited capabilities for other disciplines. Therefore, in actual wind turbine simulation systems, a joint simulation system of two or more simulation systems is often employed. Given the complexity of establishing a joint simulation system, joint simulation using two platforms is often employed. Generally speaking, wind turbine simulations utilize one platform to simulate the aerodynamic and dynamic systems (hereinafter referred to as the dynamic platform) and another to simulate the electrical and control systems (hereinafter referred to as the electrical platform), creating a dual-platform simulation system. Since the simulation platform operates in a dual-platform configuration, data inevitably flows between them, requiring synchronization. This data, particularly physical quantities that are readily available to both platforms, is crucial. The speed parameter, which describes the current rotational state of the turbine's overall dynamic and electrical systems, is a global variable that must be shared across the entire platform in real time. However, calculation of the speed variable requires collaboration between both platforms. Therefore, the calculation and synchronization of speed between the two platforms are crucial.

[0003] Under existing technical solutions, the two platforms often calculate their respective speeds based on their respective inputs and outputs. In their respective calculations, the dynamics platform simplifies the consideration of the electrical and control systems; while the electrical platform simplifies the consideration of the pneumatics and dynamics systems. When setting up the models for the two platforms, consistent parameters are used to ensure the consistency of the speed as much as possible, and no special synchronization operations are performed. However, due to the different model accuracies and the lack of synchronization operations to ensure speed consistency, there may be certain errors in the speed variables of the two platforms during the simulation process, and even cause error divergence, resulting in low simulation accuracy. Summary of the Invention
