Problems solved by technology

[0007] (1) The centralized calculation mode of the traditional hydropower station simulation model cannot guarantee the real-time calculation of the simulation system, and there is a system delay phenomenon
[0008] (2) The model coupling of the traditional hydropower station simulation system is serious and does not have scalability, resulting in low model reuse, difficult development and debugging, and long development cycle
[0009] (3) The modular modeling method based on the idea of ​​large-scale system decoupling is difficult to configure and modify the code, and the decoupled modular models are highly interdependent and cannot be reused, making it difficult to perform large-scale customization of the simulation system

Embodiment 1

[0079] Through in-depth analysis of the operating environment of hydropower stations and the interaction mechanism of equipment, it is found that in addition to traditional human-computer interaction, modern smart hydropower systems are more about interconnected interaction and autonomous operation between equipment. The equipment and systems involved in hydropower energy production have obvious advantages. Intelligent features such as active perception, analytical reasoning, and autonomous control. The unattended operation mode of smart hydropower stations is the embodiment of this feature. The hydropower equipment conducts distributed organization, loosely coupled combination, asynchronous non-blocking communication through the device bus, and completes the hydropower intelligent production process collaboratively through real-time perception and active response to various sensor signals. Inspired by this, if the intelligent perception and active service characteristics of...

Abstract

The invention belongs to the technical field of hydropower station simulation control, and discloses a hydropower station simulation method and simulation system based on active perception. The hydropower station equipment is used as the organization unit for decoupling and simulation services, and the intelligent perception and active service of hydropower equipment are used as the main line to drive the construction. model and simulation process. By rationally integrating the service composition and interaction ideas in SOA and EDA, and seamlessly integrating them into the modeling object of the hydropower environment—the simulation model of intelligent hydropower equipment, the on-demand distribution of device perception information and event-driven service collaboration are realized. , to complete the construction of the entire hydropower station simulation operating environment. The modeling method of the hydropower station simulation system provided by the present invention uses equipment as the basic unit of system decoupling and model organization, which is more in line with the operating principle of a real hydropower station, and is more clear and natural in the division of responsibilities, and is more conducive to the refinement of modeling and modeling Loose coupling, reusability and scalability, as well as mass customization of hydropower station simulation systems.
