4.5 Synchronizing Facilities p. p. 16
4.5 Synchronizing Facilities Synchronous generators and self-commutated inverters connected to the Distribution System must be equipped with synchronizing facilities to permit connection only when both the frequency and voltage are within...

AI summary Section 4.5 outlines requirements for synchronizing facilities for synchronous generators and self-commutated inverters connected to the Distribution System. These facilities must ensure connection only when frequency and voltage are within specified limits, and settings must be approved by NSPI prior to finalizing the SSGIA. The Interconnection Customer is responsible for maintaining these facilities.

Frequency Condition Distribution System Frequency Ride-Through Duration (sec) Inverter Operating Mode Clearing Time: adjustable up to & including (sec) Level 2 (OF2) Over Frequency f > 62 No Ride Through Cease to Energize 0.16 Level 1 (OF1...

AI summary The table outlines frequency conditions and corresponding operational requirements for distribution systems, including ride-through durations, inverter operating modes, and clearing times. It defines different levels of over-frequency and under-frequency conditions and their respective system responses.

Section 54 p. p. 21
The harmonic current injection from the Generating Facility to the Distribution System measured at the POI shall not exceed the limits established by IEEE 519-2022. These limits are shown below in Table 9. Table 9: Maximum Harmonic Current...

AI summary The document specifies that harmonic current injection from a generating facility to the distribution system must not exceed limits set by IEEE 519-2022, as outlined in Table 9.

5.2 Short Circuit Limitations p. p. 23
5.2 Short Circuit Limitations The design fault level of the 12.47 kV Distribution System is 9000 Amps, 194 MVA, although actual fault levels will vary from substation to substation and will decrease with distance from the substation. Short...

AI summary The 12.47 kV distribution system has a design fault level of 9000 Amps, 194 MVA, with actual levels varying by substation. Short-circuit faults are managed by reclosers or circuit breakers, which attempt to restore service up to three times. The Petpeswick Solar generator addition did not affect the fault level at the Point of Interconnection, remaining within the system's design limit.
