水轮机步进式调速器设计

Design of Stepping Speed Regulator of Water Turbine

分析了现有水轮机调速器的不足 ,设计了一种由PLC控制 ,采用步进电机驱动的新型水轮机调速器 ,经现场应用证明其设计先进 ,自动化程度高 ,稳定性好 ,所有指标均达到国家中小调标准。

On the basis of analyzing the shortcomings of present speed regulator of water turbine,this paper presents a new speed regulator of water turbine that is controlled by PLC and make use of stepping engine to drive.It is proved by on-the-spot application that this new regulator is superbly designed with high degree of automatization,good stability,and all its indexes comply with national standards.
