Relays for Various Protection Applications / SV00 SIPROTEC SV00 numerical circuit-breaker failure protection relay Fig. 0/ Description SIPROTEC SV00 numerical circuit-breaker failure protection relay The SIPROTEC SV00 is a numerical relay used for circuitbreaker failure protection. A failure occurs when the circuitbreaker fails to correctly open and clear the fault after single or three-pole trip commands have been issued by the protection unit. It is then necessary to trip the relevant busbar zone (section) to ensure fault clearance. Generally, the monitoring of the current is sufficient as the criterion for the indication that the circuit-breaker has successfully cleared the fault ( current condition ). However, under certain fault conditions (e.g. overvoltage), little or no current may flow, making the measurement of current unreliable for indication of the circuit- breaker status ( no current condition ). The SV00 operates correctly for both these conditions. The relay is suitable for use at all voltage levels and in all applications. The current transformers can either be of the closed iron core or linear type. The relay can be incorporated in conventional switchgear systems and modem substation control systems e.g. SICAM.

Relays for Various Protection Applications / SV00 Application Application The numerical circuit-breaker failure protection relay SV00 provides rapid backup fault clearance instruction to the associated circuit-breakers in case the circuit-breaker nearest to the fault fails to respond. It is suitable for power systems of all voltage levels. The initiation signal can be derived from any protection or supervision equipment or, in case of manual opening, from the control discrepancy switch of the breaker. Information from the circuit-breaker auxiliary contact is required for the breaker failure protection to function during faults which produce little or no current flow (possible only with common-phase initiation).

Relays for Various Protection Applications / SV00 Construction, protection functions Construction The relay contains all the components needed for Acquisition and evaluation of measured values Operation and display Output of signals and trip commands Input and evaluation of binary signals SCADA interface (RS) Power supply The rated CT currents applied to the SIPROTEC SV00 can be or A. This is selectable via a jumper inside the relay. Three different housings are available. The flush-mounting versions have terminals accessible from the rear. The surfacemounting version has terminals accessible from the front. LSP00-afpen.tif Protection functions Fig. 0/ Rear view of surface-mounting housing The breaker failure protection can operate single-stage or twostage. When used as single-stage protection, the bus trip command is given to the adjacent circuit-breakers if the protected feeder breaker fails. When used as two-stage protection, the first stage can be used to repeat the trip command to the relevant feeder breaker, normally on a different trip coil, if the initial trip command from the feeder protection is not successful. The second stage will result in a bus trip to the adjacent breakers, if the command of the first stage is not successful. The bus trip command from the breaker failure protection can be routed to all circuit-breakers linked to the same busbar (section) as the breaker that failed. It can also be transmitted to the remote end by means of a suitable communication link (e.g. PLC, radio wave, or optical fiber). The isolator replica which is necessary in case of multiple busbar sections is not part of the SV00 relay. The current level is monitored in each of the three phases against a set threshold. In addition, the zero-sequence component or the negative-sequence component of the phase currents derived by symmetrical component analysis is monitored. This ensures high security against malfunction by use of a -out-of- check of the current detectors. The version with phase-segregated initiation enables reliable breaker failure detection even during single-pole auto-reclose cycles, provided the phase-segregated trip signals of the feeder protection are connected to the SV00. If the protected circuit-breaker is not operational (e.g. air pressure failure or spring not charged), instantaneous bus trip of the adjacent circuit-breakers can be achieved following a feeder protection trip, provided the relay is informed via binary input of the breaker status (possible only for common-phase initiation). An end-fault protection function is integrated in the SV00 relay. An end fault is a short-circuit located between the circuitbreaker and the current transformer set of the feeder. For this fault, current flow is detected, although the auxiliary contacts of the breaker indicate open breaker poles. A command signal is generated which can be transmitted to the remote-end breaker (possible only for common-phase initiation). Special measures are taken to prevent malfunction of the relay. Besides the mentioned -out-of- check of the current detection elements, the trip signals of the feeder protection can be connected in a redundant manner, so that they can be checked for plausibility (possible only for common-phase initiation). Continuous monitoring of the measured values permits rapid annunciation of any fault in the instrument transformer circuits. Continuous plausibility monitoring of the internal measured value processing circuits and monitoring of the auxiliary voltages to ensure that they remain within tolerance are obviously inherent features. 0 Siemens SIP Edition No. 0/
