ReliabilityFirst Standard Authorization Request Form ID Authorized for Posting Authorized for Development Title of Proposed Standard: Generator Verification Data Reporting Standard SAR Requestor Information Request Date March 10, 2006 SAR Type (Check box for one of these selections.) Name: Eric Mortenson / Charlie Matassa Company: Exelon / BG&E X New Standard Telephone: (630) 576-6898 Revision to Existing Standard Fax : (630) 437-2309 Withdrawal of Existing Standard E-mail: [email protected] Urgent Action Purpose (Provide one or two sentences.) The purpose of the standard(s) is to ensure that accurate performance and modeling data for generators is developed and maintained in accordance with NERC requirements for the RRO. These data to be developed include generator gross and net real and reactive power capability and parameter data for generator modeling in system dynamics studies. Industry Need (Provide one or two sentences.) The industry needs to have accurate data for effectively modeling the bulk electric system in studies conducted to analyze the networked electric system. Therefore, testing of generator performance and dynamics modeling data and the proper reporting of the results of the testing for inclusion in system models is necessary. Brief Description (A few sentences or a paragraph.) The Standard(s) must address the requirements placed on the RRO by NERC Standards MOD013-0, MOD-024-1, MOD-025-1, MOD-026-1, and MOD-027-1. The standard drafting team should consider the value of identifying separate standards for several of the parameters in order to expedite the implementation of real and reactive output verification. To this end, the Standard(s) should establish standards for the verification / testing of real and reactive requirements of all generator owners for testing and verifying gross and net real and reactive of each unit on the system. The Standard(s) should also set requirements for the testing and reporting of generator dynamics modeling data for generator rotors; excitation system functions including voltage regulator controls, limiters, compensators, and power system stabilizers; speed governor response data; and modeling data for any other equipment required to determine an September 29, 2004 1 accurate determination of system dynamic performance in the transient timeframe. The Standard(s) should also include detailed requirements for reporting modeling data and the results of generator testing. If any generators are to be exempt from the Standard, such requirements for an exemption must be clearly defined. This standard(s) must create a uniform philosophy across the entire RFC footprint. Reliability Functions The Standard will Apply to the Following Functions (Check box for each one that applies.) Reliability Coordinator Ensures the reliability of the bulk transmission system within its Reliability Authority area. This is the highest reliability authority. Balancing Authority Integrates resource plans ahead of time, and maintains load-interchange-resource balance within its metered boundary and supports system frequency in real time Interchange Authority Authorizes valid and balanced Interchange Schedules Planning Authority Plans the bulk electric system Transmission Service Provider Provides transmission services to qualified market participants under applicable transmission service agreements Transmission Owner Owns transmission facilities Transmission Operator Operates and maintains the transmission facilities, and executes switching orders Transmission Planner Develops a long-term (generally one year and beyond) plan for the reliability (adequacy) of the interconnected bulk electric transmission systems within its portion of the Planning Authority Area Resource Planner Develops a long-term (generally one year and beyond) plan for the resource adequacy of specific loads (customer demand and energy requirements) within a Planning Authority Area. Distribution Provider Provides and operates the “wires” between the transmission system and the customer Generator Operator Operates generation unit(s) or runs a market for generation products that performs the functions of supplying energy and Interconnected Operations Services X September 29, 2004 2 Purchasing-Selling Entity X X Generator Owner The function of purchasing or selling energy, capacity and all necessary Interconnected Operations Services as required Owns and maintains generating units. Load-Serving Entity Secures energy and transmission (and related generation services) to serve the end user Regional Reliability Organizations An entity that ensures that a defined area of the Bulk Electric System is reliable, adequate and secure. 2. A member of the North American Electric Reliability Council. The Regional Reliability Organization can serve as the Compliance Monitor. September 29, 2004 3 Detailed Description (Provide enough detail so that an independent entity familiar with the industry could draft a Standard based on this description.) In order to meet NERC requirements, the Standard must include criteria for: reporting generating unit auxiliary loads acceptable methods for model and data verification, including any applicable conditions under which the data should be verified periodicity and schedule of model and data verification and reporting information to be verified and reported seasonal gross and net Real Power generating capabilities real power requirements of auxiliary loads the requirement for unit-specific dynamics data for generators and synchronous condensers (including, as appropriate to the model, items such as inertia constant, damping coefficient, saturation parameters, and direct and quadrature axes reactances and time constants), excitation systems, voltage regulators, turbine-governor systems, power system stabilizers, and other associated generation equipment the use of estimated or typical manufacturer’s dynamics data, based on units of similar design and characteristics when unit-specific dynamics data cannot be obtained; however, in no case shall other than unit-specific data be reported for generator units installed after 1990 unit size thresholds for permitting o the use of non-detailed vs. detailed models o the netting of small generating units with bus load o the combining of multiple generating units at one plant requirements for device specific dynamics data for dynamic devices, including, among others, static VAR controllers, high voltage direct current systems, flexible AC transmission systems, and static compensators dynamics data representing electrical demand characteristics as a function of frequency and voltage Dynamics data shall be consistent with the reported steady-state (power flow) data supplied per Reliability Standard MOD-010-0_R1 method of verification for all data, including dates and conditions of tests Reporting requirements must be established for: verified maximum gross and net Reactive Power capability (both lagging and leading) at Seasonal Real Power generating capabilities as reported in accordance with Reliability Standard MOD-024 Requirement 1.5.1 verified Reactive Power limitations, such as generator terminal voltage limitations, shorted rotor turns verified Reactive Power of auxiliary loads method of verification of Real and Reactive Power capabilities, including dates and conditions testing of generators for dynamic modeling data and the reporting of such data If any exemptions from reporting of the above data are permitted, generating unit exemption criteria must be established. A list of units that are exempt from a portion or all of these procedures must be documented along with the justification of the exemption.

Presently, MAIN, ECAR, MAAC and MRO have generator testing requirements for Real and Reactive Power verification in place. To the extent that the new Standard affects the requirements or timing for generator testing, a reasonable transition period must be allowed. However, all new testing requirements must be in place no later than January 1, 2008 at which point all associated legacy documents will be retired.
