Embodiment Construction

[0030] The invention provides a thyristor valve triggering and monitoring system, which relates to a reconfigurable static var compensator (SVC) / DC deicing composite device. The system is mainly divided into two parts, the trigger part and the monitoring part. The main function is to complete the triggering and monitoring functions of the thyristor valve of the reconfigurable device operating in the static var compensator (SVC) or the DC ice melting condition.

[0031] The triggering part is to analyze and code according to the trigger command sent by the control system, and after photoelectric conversion, the trigger command is sent to the high-level electronic board on the thyristor valve body through the optical cable to complete the normal trigger of the thyristor valve.

[0032] The monitoring part is to receive the return signal from the high-level electronic board of the thyristor valve through the optical cable, and the signal is in one-to-one correspondence with the t...

Abstract

The invention provides a thyristor valve triggering and monitoring system and relates to reconfigurable static var compensator (SVC)/DC ice-melting combined device. The system mainly comprises two parts of a triggering part and a monitoring part, and is mainly functionalized in that the triggering and the monitoring functions of a thyristor valve can be completed when the reconfigurable device runs under the SVC or DC ice-melting condition. As the system keeps in touch with the outside only by light signals, the precision is high, and the anti-interference capacity is strong, thereby meeting the requirement of the system.

Description

technical field [0001] The invention belongs to the technical field of electric power system transmission, and in particular relates to a thyristor valve triggering and monitoring system, which is used in a reconfigurable static var compensator (SVC) / DC deicing composite device. Background technique [0002] In order to solve the heavy losses caused by the icing disaster of transmission lines to the power system, the national economy and the whole society, a lot of analysis and research work on the icing of transmission lines has been carried out at home and abroad. Among them, it is agreed that the rectifier-based DC ice melting scheme has a very wide application space. The main principle is to use the ice-covered line as a load, short-circuit one end, apply a DC power supply to the other end, and provide a larger voltage with a lower voltage. Direct current is used to heat the wire and melt the ice on the wire. [0003] In view of the small time and frequency of ice disas...
