水电仿真中关键的模型是水机调速器模型,针对水电仿真系统中的调速器非线性数学模型问题进行分析。在建模过程中采用分段解析、拟和的方法,推导出了水电仿真中水机调速器开机和甩负荷过程数学模型,解决水机调速器中开机过速和甩负荷过程中振荡不收敛问题。水电仿真2.0和3.0版本性能评价表明,该模型在性能上优于传统的调速器仿真模型,在丰满水电仿真系统中运行良好。
The key model in hydropower simulation is the water turbine governor model, which analyzes the governor nonlinear mathematical model problem in hydropower simulation system. In the modeling process, the method of segment analysis and fitting is adopted to derive the mathematical model of hydropower governor on-off and load-shedding during water turbine governor to solve the problem of instability Do not converge. The performance evaluation of hydroelectric simulation version 2.0 and 3.0 shows that the model is superior to the traditional governor simulation model in performance and works well in Fengman hydropower simulation system.
