Protection Settings. A non-synchronous generating facility, while complying with the under-frequency and over-frequency ride through requirements, shall use accurately calculated and filtered frequency measurement over a time window to set frequency protection and should not use an instantaneously calculated value to set frequency protection. A non-synchronous generating facility, while complying with the under-voltage and over-voltage ride through requirements should use filtered Root-Mean-Squared (RMS) voltage measurement to set voltage protection. Inverter rate-of-change-of-frequency (ROCOF) protection shall be disabled unless an equipment limitation exists that requires the inverter to trip on high ROCOF.

Appendix H Interconnection Requirements for Provisional GIA Provisional Agreement This GIA is being provided in accordance with Section 11.5 of the Transmission Provider’s GIP, which provides among other things, that an Interconnection Customer may request that Transmission Provider provide Interconnection Customer with a provisional GIA that limits the transfer of energy by Interconnection Customer commensurate with that allowed for Energy Resource Interconnection Service. Interconnection Customer requested Transmission Provider to provide a provisional GIA for limited operation at the discretion of Transmission Provider based upon the results of available studies (by Interconnection Customer and by Transmission Provider). A Provisional Interconnection Study, the results of which are posted on the confidential portion of the Transmission Provider’s internet website, was performed by Transmission Provider in order to confirm the facilities that are required for provisional Interconnection Service and to require them to be in place prior to commencement of service under the GIA. Interconnection Customer represents that the Interconnection Customer facilities (including Network Upgrades, Interconnection Facilities, Distribution Upgrades, System Protection Upgrades and/or Generator Upgrades) that are necessary to commence provisional Interconnection Service and meet the requirements of NERC, or any applicable regional entity for the interconnection of a new generator are in place prior to the commencement of generation from the Generating Facility and will remain in place during the term of the service. The requisite Interconnection Studies were performed for the Generating Facility. Interconnection Customer shall meet any additional requirements (including reactive power re...

Effective On: July 20, 2022 MISO Attachment X: Appendix 6 FERC Electric Tariff Generator Interconnection Agreement (GIA) ATTACHMENTS 91.0.0 Inverter rate-of-change-of-frequency (ROCOF) protection shall be disabled unless an equipment limitation exists that requires the inverter to trip on high ROCOF. For the DPP-2022-Cycle, Interconnection Customers may request exceptions to IEEE 2800-2022 requirements cited herein based on only if specific limitations or uncertainties of equipment or plant capabilities prevent implementation of these requirements. Interconnection Customers requesting exceptions shall submit documentation to the Transmission Provider outlining the specific IEEE 2800-2800 subclauses pertinent to the request along with information from the manufacturer regarding the nature of the issue conforming to or assessing conformance with requirements herein. The Transmission Provider will, in good faith, accept Original Equipment Manufacturer (OEM)-documented requirement exceptions and document these exceptions in Appendix C of this GIA. Commented [PD16]: Rev 2: Added language on flexibility in response to stakeholder comments on OEM readiness. If the performance or capability exception can be mitigated through equipment firmware upgrades still under development, the Interconnection Customer shall implement the firmware upgrade within sixty (60) calendar days of commercial availability of such firmware. GIAs signed on or after January 1, 2025, are not eligible for requirement exceptions. Further, the process for establishing exceptions shall not apply beyond the DPP-2022-Cycle.
Protection Settings. Relay settings for all unit type protective schemes and for distance relay shall be submitted to KPLC prior to commissioning of the Olkaria III substation and Transmission Interconnector for approval. Settings shall also be provided for those relays and other equipment provided under this Section of the Contract which do not require an intimate knowledge of existing relay settings e.g. circuit breaker fail relays. Details calculations shall be provided supporting the recommended settings. The back Overcurrent and Earth Fault Relays shall be set using Normal Inverse Time-Current characteristics for IEC 60255 or BS 142. The Relay shall be set to ensure coordination with other relays existing at Olkaria II substation.
Protection Settings. To be advised 6. Terminal Sub-Station – Interest Required: Freehold
Protection Settings. A non-synchronous generating facility, while complying with the under-frequency and over-frequency ride through requirements, shall use accurately calculated and filtered frequency measurement over a time window to set frequency protection and should not use an instantaneously calculated value to set frequency protection.
Protection Settings. A list of the settings to be applied to all protection equipment together with all associated calculations shall be provided for review and approval not less than 3 months prior to the first scheduled date for commissioning. Any limitations imposed on the power system as a result of the settings proposed shall be explicitly stated. In the absence of system data required for calculation purposes, assumptions may be made providing these are clearly identified as such in the relevant calculations. A CD shall be submitted with the final documentation package that shall contain all final relay settings in a database that can be used, or modified, and loaded into each relay through its front panel RS232 port from a laptop computer. Protective, control and automation settings from 138kV to the 4160/480V low-side main breakers including generator protection will be suggested by Company’s Relay Engineer, but shall be verified, approved and set by Contractor. This does not include the settings for the GE supplied Xxxxxxxx M-3425 relays. Company’s Relay Engineer shall review finalized settings prior to energization. Company’s Relay Engineer shall be provided finalized settings for review at least three months prior to commissioning. Contractor shall be responsible for coordinating with GE the appropriate settings for the Xxxxxxxx M-3425 IGPS relays supplied with the combustion turbine generators. Contractor shall provide these settings as part of the comprehensive/coordinated protection scheme. Contractor shall be responsible for coordinating with the MPSA the appropriate protective settings for the SEL300G relays supplied with the steam turbine generator. Contractor shall provide these settings as part of the comprehensive/coordinated protection scheme.
Protection Settings. As a minimum the Generator shall apply the protection requirements set out in Engineering Recommendation G59/1. The exact test and protection settings will be notified to the Parties in writing at a future date to be agreed. The protection tests should include the testing of the vector shift relays response to the change of voltage vector by secondary injection.
