【Abstract】 Prime mover simulation system is an important equipment used in power system dynamic simulation laboratory. It simulates the real prime mover (hydraulic turbine and steam turbine) and its speed governor in the power system to study the large interference problem and electromechanical transient process in the power system. By analyzing the characteristics of the prime mover and its speed governor, the principle of mathematical similarity is applied, and the DC motor and its control system are used to simulate the prime mover and its speed governor. In the past, the control of the prime mover simulation system was generally realized by analog circuit or analog-digital circuit combination. Due to the shortcomings of analog circuit, such as complex structure, easy aging of electronic components, easy influence of ambient temperature, and poor anti-interference ability, the study of fully digital controlled prime mover simulation system has important theoretical and practical significance for overcoming the above shortcomings and improving the accuracy and reliability of prime mover system simulation. The main contents of this paper include the following aspects: 1. Combined with a large amount of literature, this paper introduces in detail the development of prime mover simulation and the significance of realizing full digitalization of prime mover speed control. 2. Based on the existing achievements of prime mover simulation research, a general mathematical model reflecting the characteristics of the prime mover and its speed control system is established, and on this basis, it is discretized and its functions are realized by flexible computer software. 3. Based on the DSP chip TMS320LF2407A, the hardware circuit of the prime mover simulation system is designed, including the main circuit, operation circuit and control circuit. 4. Based on the control circuit, the design idea of the software is fully explained, and the genetic...
