摘要
对水轮机调速系统建立数学模型,利用Matlab软件,对中小型水轮机调速系统进行模型搭建,并进行有负载(有功功率800 k W,无功功率400 k W)和加负载(有功功率800 k W)在标幺值下的有差调节仿真。仿真结果显示:加载前,机组频率在短时间震荡后稳定在1附近;加载时,水轮机经过短暂的震荡调整,很快稳定在标幺值1附近并实现平衡,实现了水轮机的有差调节。
This paper set a mathematical model of the small and medium-sized hydro turbine governing system by using the Mathworks Matlab software. Line load（ active power 800 kw,reactive power 400kw） and load（ active power 800 kw） in the initial investors adjust under MAO value was simulated. The result showed that before loading,unit frequency after oscillation in a short time was stabilized near 1; in the load process,the oscillation of the water turbine after a short adjustment,quickly stabilized and balanced near the MAO value 1,and it realized the investors adjust of water turbine regulation.
