This paper deals with the basic principles of the modularity modelling method, establishing the models of components,and a general method of generating the system model from the models of components. Furthermore,the mathematical model of the hydraulic metering system is built up by this modlling method and computer simulation is performed on real practice. The result indicates that the model is correct and method is reliable and easy for computer-aided modelling and simulation with its particular advantages in the combination of dynaic and static simulation. This method can simplify the modelling that is needed in simulation, generalize the mathematical model,and be suited for modelling and simulatign the large-scale system.
