摘要： PROBLEM TO BE SOLVED: To assure absorption of regenerative power from an electric rolling stock without causing an increase in the capacity of a storage battery or an electric double layer capacitor, and without jumboizing a device. SOLUTION: An energy storage device absorbing regenerative power from an electric rolling stock and supplying electric power to a wire side comprises the electric double layer capacitor 22 performing rapid charging/discharging electricity to the wire side through rise and fall choppers 24A, 24B, and a resisting device 23 for dissipating only an excess of the regenerative power as heat when the generation of the regenerative power on the wire side becomes too much to be absorbed by the storage battery or the capacitor, which is arranged in parallel with the storage battery 21 for charging/discharging high power to the wire side. The resisting device 23 includes a discharging means in fear of excessive charge in the storage battery by the regenerative power. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To control the reception of the power of a power storage device from a feeder line at an adequate timing without being affected by the fluctuation of the received voltage of a transformer station for an electric railroad vehicle.
SOLUTION: A control device 53 calculates the reference discharge voltage V
D (t)* and the reference charge voltage V
C (t)* on the real time manner based on the rectifier output voltage V(t) detected by a voltage detector 44 and the rectifier output current I(t) detected by a current detector 45. When the line voltage V detected by the voltage detector 54 is below the reference discharge voltage V
D (t)*, the control device 53 controls a power converter 52 so that the feeder voltage V is kept at the value not lower than the lower limit value of its rated range by the discharge power from a power storage medium 51. Further, when the feeder voltage V is above the reference charge voltage V
C (t)*, the control device controls the power converter 52 so that the power regenerative energy generated when applying the brake of an electric railroad vehicle is absorbed by the discharge power to the power storage medium 51.

摘要： PROBLEM TO BE SOLVED: To solve the problem in an energy storage device that simply storing regenerative power from an electric railroad into a battery and regenerating it results in poor efficiency of utilizing the device and poor efficiency of facilities. SOLUTION: A step-up/step-down chopper 12 lowers that portion of the voltage of a dc power storage device 11 which does not contribute to charge to and discharge from a feeder, to thereby achieve a high step-up/step-down ratio for achieving desired charge and discharge voltages, for the purposes of controlling a charge current from the feeder to the dc power storage device 11 when the feeder voltage is equal to or greater than a charge-controlling set voltage and of controlling a discharge current from the storage device to the feeder when the feeder voltage is equal to or less than a discharge-controlling set voltage. A stopper switch 13 blocks a natural discharge from the storage device to the feeder side through the chopper. A filter capacitor 14 and a reactor 15 suppress higher harmonies flowing from the chopper to the feeder side. A current detector 20 performs current detection for controlling the charge and discharge currents of the chopper.

摘要： PROBLEM TO BE SOLVED: To decrease the number of converters to be installed by preventing the occurrence of the drop of a driving force at the time when a car crosses a section, even if power is fed to neighboring sections from the same converter. SOLUTION: In addition to the usual feeding section switches SFn (where n is a natural number), short-circuiting switches SSn which short-circuit or open the end of each section Sn , and cross over switches SWn which open or close the connection between the end of each section Sn and the input terminal of the next section Sn+1 are provided. These switches are controlled by a feeder controller 2. While a car is within the section Sn , SFn and SSn are closed with the others opened. When the car is about to reach the boundary line with the section Sn+1 , SSn is opened, and SSn+1 and SWn closed. When the car crossed the boundary line, SFn and SWn are opened, SSn+1 being left closed.
