The synchronous condenser coupled with flywheel energy storage via field-modulated planetary-geared speed regulator(FMPGSR)is a new technology used to enhance the transient voltage and frequency support for the modern power grid.In comparison to the traditional field-modulated magnetic-geared speed regulator(FMMGSR),the FMPGSR strengthens the capability of torque transmission between the flywheel and the synchronous condenser by introducing the field-modulated planetary gears.To calculate the equilibrium angles of the planetary gears,this paper proposes an optimization algorithm based on precondition technique and gradient decent method with self-adaptive steps.Incorporated with the finite element method,this algorithm supports the electromagnetic analysis and design of FMPGSR as an efficient and accurate simulation tool.For further increase of the FMPGSR's torque density,this paper optimizes the electromagnetic designs of inner rotor with different permanent magnet arrangements and proposes a scheme with Halbach array.
