Rotor Function Design
This image depicts the internal structure of the rotor function used in the VSG model in Simulink environment. It shows the computation of the rotor speed and angle based on the difference between mechanical and electrical power. The block diagram includes mathematical operations such as division, summation, and integration, which help determine the rotor's dynamic response. A damping factor (D) and inertia constant (J) are used to model the realistic behavior of the virtual rotor, ensuring an accurate simulation of synchronous generator characteristics.
Double-Loop Controller Design
This image provides a detailed view of the double-loop control mechanism within the VSG model in Simulink envirenment. It consists of PI controllers responsible for regulating the direct (d-axis) and quadrature (q-axis) components of voltage and current. The control loops compare reference values (V_star_d and V_star_q) with actual feedback signals to generate appropriate control signals for voltage regulation. The dq0-to-abc transformation block converts the controlled dq-axis values back to three-phase voltages for the inverter output. This control structure ensures stability and proper functioning of the VSG under varying load conditions.
Virtual Synchronous Generator Design
This represents a Simulink model for a virtual synchronous generator (VSG) with a double-loop control system. The diagram includes a rotor function block that calculates the rotor angle (theta) and speed (w) based on input mechanical (Pm) and electrical (Pe) power. The calculated values are then used to generate sine wave signals, which are further processed to obtain the dq0 transformation, eventually feeding into the double-loop control block. The purpose of this model is to simulate the behavior of a VSG and regulate its output voltage.
Final Design
Parameter selections are currently in progress. So, the simulation results are not included yet.
