Abstract: An adjustment mechanism for an electric power-driven shoe, the mechanism comprising a shoe sole (1) is presented, wherein a plurality of rolling wheels (2) are arranged below the shoe sole (1); a foot-positioning mechanism is arranged above the shoe sole (1) and is provided with an angle-adjusting mechanism for adjusting an angle between the foot-positioning mechanism and a lengthwise direction of the shoe sole (1).

Abstract: The present application discloses a flexible excitation system and a method for controlling the same. The flexible excitation system consists of a plurality of groups of flexible excitation power units connected in parallel, a deexcitation circuit unit and a flexible excitation control unit. The method for controlling the flexible excitation system includes: realizing the internal fault-tolerant operation control of the flexible excitation power units by cooperatively controlling AC circuit breakers and DC circuit breakers of the flexible excitation power units and a deexcitation switch; dynamically controlling ceiling voltage when terminal voltage drops by using the fast response control ability of the flexible excitation system, so as to improve the forced excitation output capacity of the self-shunt excitation system.
