Design and Simulation of a 12-Phase Flywheel Energy Storage Generator System With Linearly Dynamic Load

Based on an original 12 kW 12-phase synchronous generator system, this paper presents the design scheme and computationally efficient simulation model of a 12-phase flywheel energy storage generator system with linearly dynamic load. In the designed system, the module functions of linearly dynamic load and excitation power amplifier are respectively performed by a Buck converter and full-bridge converter, and a joint algorithm of feedforward and feedback is adopted in the innovative excitation controller module. The system simulation model is built in EMTDC environment, where the machine models are obtained from secondary development in FORTRAN language. The simulation results show that all the designed modules can fulfill their basic functions, the active power of linearly dynamic load increases at the expected rate, the control precision and response speed of the system are satisfactory, and the solution of system simulation model is exact and fast.
