Problems solved by technology
[0005] However, the tram control device disclosed in Patent Document 1 has a problem that, during the regenerative operation, when the electrical connection between the trolley line and the pantograph is interrupted due to the laying state of the trolley line or the running condition of the tram, or when the power supply in the substation When the electrical connection between the pantograph and the trolley line is interrupted at the discontinuity with the substation (hereinafter referred to as "off-line"), the regenerative power that cannot be supplied to the trolley line and has nowhere to go cannot be consumed by the brake resistor

The invention discloses an electric car control device, which prevents auxiliary power equipment stop working because of uprise of pressure of conductive bow point. The electric car control device (30) is connected with a power conversion apparatus (7) that converts AC from an electric motor (9) to DC, detects dump power of consumed power of regenerated load carried by the auxiliary power unit (8), controls a brake amputator (5) that connects with a brake fled rheostat (6) that comsumes dump power, and comprises the following components: a first voltage detector (4) that detects voltage (1D) of a filter capacitor (3) that connected with the power conversion apparatus (7) in parallel; a second voltage detector (1) that detects the conductive bow point voltage (4D); a first circulation ratecalculator (22) that generates a first circulation rate (3D) based on voltage (1D); and a second circulation rate calculator (22) that generates a second circulation rate (6D) based on conducive bow point voltage (4D).
Description
technical field [0001] The present invention relates to an electric vehicle control device, and more particularly to an electric vehicle control device that controls a brake chopper device that consumes a part of regenerative power generated during electric braking. Background technique [0002] The power conversion device mounted on the train converts DC power supplied through a pantograph or a filter circuit into AC power of a predetermined output during power running, and controls the motor. On the other hand, when operating the electric brake, the power conversion device converts the AC power generated by the motor into a predetermined DC power. This DC power is consumed by regenerative loads of the electric train, for example, an auxiliary power supply device (SIV: Static InVerter) for driving an air conditioner mounted on the electric train, or other electric cars on the same train line. Here, the power portion exceeding the power that can be consumed by the regenerat...
