摘　　要：传统多喷针冲击式水轮机组大多采用基于开度模型的调速器控制策略,调节时间和超调量较大,严重影响机组功率调节质量。为了提高机组在喷针切换过程中功率的稳定性,考虑喷针开度与流量的非线性关系,提出了一种基于流量模型的调速器控制策略。仿真结果表明,相较传统方法,其能显著降低流量波动峰值,有效保持功率稳定并减小调节时间。Traditional multi-jet impulse hydro-turbine units usually adopt a governor control strategy based on opening model,which is of large adjustment time and overshoot that may seriously affect the power regulation quality of the units.In order to improve the stability of the power during the jet switching process,a governor control strategy based on flow model is proposed considering the nonlinear relationship between the jet opening and the flow rate.The simulation results show that the proposed strategy can significantly reduce the peak flow fluctuation,effectively maintain the power stability,and reduce the adjustment time compared to traditional methods.
