摘　　要：随着大容量水电机组和大规模新能源并网运行,水轮机调速系统作为电网调峰调频主要控制设备承担越来越繁重的调控任务,其健康状态直接关系到水电站安全稳定和发电效率。基于数字孪生五维模型,依据调速系统运行原理和空间结构,提出一种面向数字孪生思想的水轮机调速系统状态评估新框架,建立了水轮机调速系统数字孪生模型,包括三维物理模型、运行机理模型和数据驱动模型,并以其为支撑完成面向数字孪生的水轮机调速系统状态评估系统构建。可为水电机组数字孪生建模提供参考。With the grid-connected operation of large-capacity hydropower units and large-scale new energy sources,the hydro-turbine speed governing system,as the main control equipment of peak regulation and frequency regulation in the power grid,has taken on more and more heavy tasks of regulation and control.Its health status is directly related to the safety and stability of hydropower stations and power generation efficiency.Based on the digital twin five-dimensional model,according to the operating principle and spatial structure of the governing system,a new state evaluation framework for the speed regulation system of hydraulic turbine is proposed in this paper.A digital twin model of hydraulic turbine speed regulation system is established,including a three-dimensional physical model,an Operation Mechanism model and a data-driven model.The digital twin model is used as a support to complete the construction of a state assessment system for the turbine speed regulation system for digital twins.It can provide reference for the digital twin modeling of hydropower unit.
