1Reliability
If a stability control device program is ported from an embedded device to a personal computer and an interface program is programmed to construct a virtual device simulation model, then the simulation model can be built, but the simulation accuracy becomes unstable
Solution Approach 1:
The patent creates a virtual device simulation model that copies the functionality and interface behavior of the actual stability control device. By extracting external interface functions from the actual device program and generating corresponding callback interface functions in the virtual model, the simulation accurately replicates the hardware's behavior, ensuring stable simulation accuracy while avoiding manual programming errors.
2Ease of manufacture
If foreign-based prototypes are used to construct simulation models, then the model construction is simplified, but the simulation accuracy deteriorates due to differences from domestic power systems
Solution Approach 1:
The patent applies local quality by extracting the specific external interface functions from actual domestic stability control devices and using these to generate callback interface functions. This ensures that the virtual device simulation model reflects the specific characteristics and behaviors of domestic power system devices, rather than using generic foreign-based prototypes, thereby achieving both ease of construction and high simulation accuracy.

AI summary
An electric power stability control simulation model construction method and apparatus, and an electric power stability control simulation system. According to an external interface function extracted from a stability control device program, a corresponding callback interface function is generated by using the external interface function, and an electric power stability control simulation model is constructed by means of the callback interface function in combination with the correspondence between the callback interface function and the external interface function. When the electric power stability control simulation model is executed to perform a simulation test, the corresponding external interface function can be called by means of the callback interface function, so that the function simulation of the corresponding stability control device program can be realized.
