System Protection. To prevent compromise of systems which contain DSHS Data or through which that Data passes:
System Protection. Interconnection Customer shall, at its expense, install, operate and maintain such System Protection Facilities as may be required in connection with operation of the Customer Facility and the Customer Interconnection Facilities consistent with Applicable Technical Requirements and Standards. Interconnected Transmission Owner shall install any System Protection Facilities that may be required, as determined by Transmission Provider, on the Transmission Owner Interconnection Facilities or the Transmission System in connection with the operation of the Customer Facility and the Customer Interconnection Facilities. Responsibility for the cost of any System Protection Facilities required on the Transmission Owner Interconnection Facilities or the Transmission System shall be allocated as provided in Section 217 of the Tariff.
System Protection. The Interconnection Customer shall install and maintain protection systems in accordance with applicable provisions of the ISO New England Operating Documents, Applicable Reliability Standards, or successor documents.
System Protection. Project Developer shall, at its expense, install, operate and maintain such System Protection Facilities as may be required in connection with operation of the Generating Facility or Merchant Transmission Facility and the Project Developer Interconnection Facilities consistent with Applicable Technical Requirements and Standards. Transmission Owner shall install any System Protection Facilities that may be required, as determined by Transmission Provider, on the Transmission Owner Interconnection Facilities and Transmission Owner Upgrades or the Transmission System in connection with the operation of the Generating Facility or Merchant Transmission Facility and the Project Developer Interconnection Facilities. Responsibility for the cost of any System Protection Facilities required on the Transmission Owner Interconnection Facilities and Transmission Owner Upgrades or the Transmission System shall be allocated as provided in GIP, section [to be determined].
System Protection a) Station Tap The station tap line shall be protected with two (2) line current differential relays (SEL 311L). The ‘A’ and ‘B’ package line protection shall perform breaker failure protection, and Direct Transfer Trip (“DTT”) transmit and received. It is preferred that the line protection use redundant ‘A’ and ‘B’ fiber lines where the redundant lines are physically separate and fully independent of each other. However, if the Interconnection Customer is unable to accommodate this, the station tap will be tripped for loss of communication. If the 115-46kV transformers at the Boonville Station are faulted or a 115kV bus fault occurs, the generation must be removed. DTT will be used to trip the generation, and the capability of the line differential relays will be used for DTT. DTT received from the Boonville Station will be required to trip the Interconnection Customer’s 46kV breaker for breaker failure. The Interconnection Customer shall provide on/off switches for line protection and DTT schemes.
System Protection. To prevent compromise of systems which contain DCYF Data or through which that Data passes:
System Protection. At the DC facilities, system protection is installed in the form of an emergency power function. Activation criteria for emergency power can be locally-measured frequency and voltage or via telecommunications on the basis of a supplied signal. In the event of activation, any ongoing normal regulation will be interrupted. Activation over and above the agreed limits and regulation back to plan may not occur until the counterparty has approved this. (See further in Appendix 5 – System protection).
System Protection. System protection is used to limit the consequences of faults over and above the disconnection of defective components. System protection can have as its purpose to increase the system security, the transmission capacity, or a combination of these. For system protection that is used to increase the transmission capacity, the following requirements have been set: • An analysis must be implemented which shows the consequences for the power system in the event of a correct, unwarranted and missing function and simultaneously takes into account the other system protection • In the event of a correct or unwarranted function, serious operational disturbances will not be accepted in other subsystems • If the above consequence analysis shows that a missing function can entail serious operational disturbances for other subsystems, the following technical requirements shall apply to the system protection function: - Redundant telecommunications shall exist in cases where system protection is dependent on telecommunications Redundant telecommunications means that communications between the stations concerned shall be entirely duplicated. If the auxiliary power feed for one of the communications systems fails, then the other must not be affected. In practice, this means that batteries, telecom terminals, converters and communication paths must be duplicated. Communication paths may not, on any section, share connections, leads, opto cables or similar. They must take geographically separated routes. Multiplexed links can be used but communications shall use separated multiplexes that are not fed by the same battery. Having separate fuses on the same battery does not constitute full redundancy. - There must be real time monitoring of telecommunications - There must be a redundant and independent ”triggering function” A redundant triggering function, if this relates to breakers, means that the breaker has two trip magnets. Breaker fault protection shall be used to safeguard breaker operation if the ordinary breakers are not functioning correctly - The control facility and telecommunications standard shall be on the same acceptable reliability level as the one applicable to primary relay protection • If a consequence analysis shows that a missing function will not entail serious operational disturbances for other subsystems, the relevant subsystem’s system operator will decide which requirements apply to the system protection function. • If a consequence analysis shows th...
System Protection. System protection can be used to increase the transmission capacity and/or system security between and within the subsystems. The settings and operational status of system protection shall be decided upon and monitored by the respective Party. In cases when system protection has a bearing on two or more subsystems, co-ordination and communication of the operating status shall take place between the Parties concerned. The requirements relating to system protection are set out in Appendix 2. The forms of system protection used are set out in Appendix 5.
System Protection a) Line 10 The Connecting Transmission Owner’s Line 10 shall be protected using redundant protection schemes. The “A” package shall be a permissive overreaching transfer trip (“POTT”) scheme consisting of an ERLPhase LPRO and GARD 8000. The “B” package protection will be a step distance scheme consisting of SEL-321. Direct transfer trip (“DTT”) will be used between the Pattersonville Collector Substation and line terminals at Meco and Rotterdam Stations to ensure removal of the generation. This will require the installation of two (2) GARD 8000 teleprotection sets at the Pattersonville Collector Substation. The Connecting Transmission Owner will provide details on the GARD 8000 model number with the Connecting Transmission Owner’s logic during detailed design. The Interconnection Customer is to provide redundant 115kV line protection to remove the generation for line faults. Two (2) sets of multi-ratio current transformers (“CTs”) shall be provided on the Interconnection Customer’s 115kV breaker for use in the protection schemes.
