The Simulation Validation of Control Characteristics and Parameters Analysis for Voltage Controlled Virtual Synchronous Generator

Through simulating the mechanical motion equations of synchronous generator, applying the synchronous generator mathematical model for converter control strategy and formed the voltage controlled virtual synchronous generator. This paper proposed the prime motor regulation and excitation regulation algorithm, and simulating the inertial of synchronous generator. As a result, the voltage controlled virtual synchronous generator has the function of active power frequency regulation and reactive power voltage regulation, and solving the problems of impendences and damping is low under grid-connected with power grid, also supporting the power grid safe and stable operation. By building the Matlab/Simulink models, this paper validates the voltage controlled virtual synchronous generator is able to simulate the operation characteristics of synchronous generator. In addition, this paper analysis the different parameters of virtual inertial, damping, integration and droop effects the control ability by simulation, and proposed the optimal parameters range for engineering application.
