Facility Connection RequirementsMay 1, 2005
Generating equipment owners shall annually test the gross and net dependable summer and winter capability of their units. These test results shall be provided to FPL-NED and ISO-NE in accordance with all applicable rules and procedures.
Generating equipment owners shall test the gross and net reactive capability of their units at least every five years, or on such intervals as required by ISO-NE rules and procedures. These test results shall be provided to FPL-NED and ISO-NE.
Generating equipment owners shall test the AVR control and limit functions of their units at least every five years or on such intervals as required by ISO-NE rules and procedures. An initial test result shall be provided to FPL-NED prior to commercial operation and every five years thereafter. The initial test results shall include documentation of the settings AVR control and limit functions. Typical AVR limit functions are; maximum and minimum excitation limiters and volts per hertz limiters. Documentation of the generator protection that coordinates with these limit functions shall also be provided. Typical generator protection of this type includes overexcitition protection, loss of field protection.
II. H. Power Factor
For synchronous generators the facilities shall be designed, operated and controlled to provide reactive power requirements consistent with policies and standards of ISO-NE and the ISO-NE Tariff. Induction generators shall have static capacitors that provide magnetizing current requirements of the induction generator field consistent with policies and standards of ISO-NE.
II. I. Interrupting Ratings
AC high voltage circuit breakers are specified by operating voltage, continuous current, interrupting current, and operating time in accordance with ANSI/IEEE Standards C37 series, “Symmetrical Current Basis.” These ratings are displayed on the individual Circuit Breaker nameplate. Breakers are scheduled for replacement when they exceed 100% of ANSI C37 Guidelines.
There may be cases where adding generation will increase the available fault current above the present interrupting ratings of the existing breakers at a substation or stations. When this occurs, breaker upgrades are to be considered as part of the interconnection project. Similarly, the connection of new generators to the transmission system may increase fault current to a level which exceeds the short time rating of overhead ground wires. The rating of overhead ground wires shall be accordance with NEPOOL Capacity Ratings Procedure document which is posted on the ISO-NE webpage. If equipment ratings will be exceeded, the appropriate modifications must be performed prior to the new generation coming on line.
3 Sections H1, H2, H3, and H4 are required by NERC Planning Standards, section II. B.
