Title: Apparatus, System and Method for controlling Thyristor Controlled Series Capacitor
IPC: H02H3/087
Filed: 2020-05-13
Abstract: When there is a low current condition among the two-line lines, an integrated controller opens the bypass switch of one of the two-line TCSCs and cuts the thyristor at the same time so that the line current flows only through the series capacitor. After that, when the line impedance is compensated due to the series capacitor and the power current increases and the current becomes a low current state (more than 10% of the rated current), enough voltage is applied for the thyristor to operate, so that thyristor switching control is started. After that, after the system is stabilized in the transient state, a command to open the bypass switch is given to the remaining TCSCs. The later opening of the bypass switch of TCSC opens at the current 0 point, so a sudden voltage change does not occur. At this time, when the remaining TCSC thyristors are in the block state, the remaining TCSC current flows only through the series capacitor. Line compensation is achieved by a series capacitor. Therefore, a current greater than or equal to the low current flows through the remaining lines. A voltage is applied to the capacitor to drive the thyristor. After that, the thyristor control reactor is started to gradually impedance control the TCSC.
