Experiences in Setting Protections of Series Capacitor Compensated Lines
نویسنده
چکیده
The protection of series compensated lines, in particular with capacitors located at the end of the line, present many difficulties. The satisfactory setting of line and capacitor protections requires time domain simulations including the protection model. In most complicated cases, the connection of the real protections to digital or analogical simulators becomes necessary. Using this approach, protections are settled as a system and not individually. Experiences of setting protections in high voltage systems with series compensation at line ends, using a Transient Network Analyzer (TNA), are shown in this paper. Some particular problems are examined, including main criteria used for setting of transmissions systems, which are nowadays in operation.
