Abstract

Abstract: The electric braking system of 300MVA motor generator (MG) adopts the operation mode of
combining electric braking and mechanical braking to rapidly shutdown the MG in case of frequent start-stop and
major failure. The specific characteristics of the MG electrical braking system is introduced, and the electrical
braking system of six-phase synchronous MG is analyzed theoretically and its' main circuit and control scheme is
given. Based on the verified generator model, the dynamic simulation of the electric braking process of the unit
under normal and extreme working conditions is carried out, and the main design parameters are determined, with
the braking excitation voltage and braking resistance being 40V and 0.1Ω, respectively.

Key words: HL-2M tokamak, Motor generator, Six-phase generator, Electrical braking, Braking resistance
