御装置。 ・A thyristor rectifier equipped with an inverter function converts AC power into DC power to operate the train, while a thyristor rectifier switches the connection between the minute iris rectifier and the overhead line during regenerative operation using a thyristor switch. In a regenerative substation for railways that recovers regenerative power to the power supply side through inverter operation, the first comparator compares the overhead line voltage and the inverter DC back electromotive voltage to confirm that the inverter DC back electromotive voltage is higher than the overhead line voltage. and a second comparator that compares the overhead line voltage with the reference level of the power running-regeneration setting device and outputs a predetermined signal under the condition that the overhead line voltage is <the reference level. a monostable multivibrator that is activated and provides an interrupt signal to the phase control section of the thyristor rectifier in order to increase the DC back electromotive voltage of the thyristor rectifier for a certain period of time; and a logical product of the outputs of the first and second comparators. Take
A logic circuit that switches the rectifier from inverter operation to converter operation when conditions are met, and switches the converter operation command and inverter operation command of the Cyrisk rectifier,
It is equipped with a circuit that creates a phase control signal based on the deviation between the set value and the detected value, and reverse biases the Cyrisk switch using the difference voltage between the output voltage of the Cyrisk rectifier and the overhead line voltage before switching from regenerative operation to continuous operation. A silisk switch control device for a regenerative substation for electric railways, characterized in that it is turned off.・
