Research Of Assessment On Simulation Accuracy Of Prime Mover System Simulator Based On MATLAB

With the increasingly complexity of power grid, in consideration of the safetyoperation of power system we need to master its accurate dynamic characteristics.This must rely on the power system dynamic simulation tools. The prime moversystem simulator is a primary device of the power system dynamic simulation. Thesimulation of the power system real mover (mainly including turbine and steamturbine) and its governor in the lab is to study the problem of big disturbance and theelectrical and mechanical transient process of power system. Therefore, the study ofthe law of operation and control of prime mover system and introduce of simulationmodel of prime mover system in the power system dynamic simulation laboratorywhich has highly accuracy and can correctly reflect the simulation test accuracy andreliability of the power system physical simulation experiment.The development process of prime mover system is more to reflect in the aspectsof control technology and operation speed. In order to promote the prime moversystem to a higher level development, it is necessary to carry out the simulationaccuracy evaluation of prime mover system simulator. The simulation accuracyresearch of prime mover system simulator is the motive power to promote thedevelopment of the prime mover system simulation.Firstly, on the basis of consulting a large number of literature, the currentsituation of the prime mover system simulator and actual prime mover system areintroduced.
