Description
Summary:A real-time simulation model is proposed, based on one hand on the hybrid calculator principle and on the other hand on original hardware, made up of a control apparatus and DPLL, for studying the inverter-fed network operation. Moreover, we show that this simulator constitutes a powerful tool for designing the control systems. The simulator and control apparatus are based on both analog and digital components. This makes possible to change, in some limits, by varying via an interface connected to the microcomputer the values of the simulated components and also parameters relative to the PWM based control apparatus A software written in a high level language permits, after the introduction of the different system parameters via an user- friendliness menu, the computation of the required calculations for the simulator. Hence the feasibility is established and it is shown through examples that good results can be obtained.
