THYRISTOR CONTROLLED SERIES CAPACITOR ADAPTED TO DAMP SUB SYNCHRONOUS RESONANCES |
摘要 |
<p>An apparatus for controlling a thyristor controlled series capacitor connected to a power transmission line. A thyristor firing control includes a unit for effectuating a desired capacitor voltage zero crossing in dependence of a line current and a capacitor voltage in response to a command signal. A command control provides the command signal to the thyristor firing control. The command control includes a damping control including a damper configured to damp at a least one discrete frequency.</p> |
