摘　　要：针对数字化模拟方法的可靠性高、适应能力强和成本低等特点,对水轮机及其调速系统的物理元件进行数学建模,运用数字化思想对水轮机及其调速系统的动静态特性进行模拟,并采用直接转矩补偿的方法对模拟系统的转动惯量进行补偿,优化系统性能。在水轮机调速系统数字化模拟的基础上,应用该系统带动同步发电机模拟水力发电系统。实验结果表明,该数字化模拟装置能够较准确地模拟电力系统的各种特性。In view of high reliability characteristics, strong adaptability and low cost of the digital simulation method, the mathematical model of the Hydraulic Turbine Governing System is established, and dynamic and static characteristics of Hydraulic Turbine Governing System are simulated by using digital thought. To optimize system performance, system speed is compensated by the method of direct torque compensation, which is based on digital simulation of hydraulic turbine governing system. This system drives synchronous generator to simulate the hydro electric power generation system. Experimental results show that the digital simulation system can more accurately simulate all kinds of power system of characteristics.
