A 750 kcmil grounding grid is to be installed under the building and continues outside into the main substation yard. (3) . The 345kV GIS consists of a four (4) circuit breakers ring bus (with the ability to expand to a five (5) circuit breaker ring bus), SF6 type, 63kA rating, 362 kV, 3000Amps. The G13 feeder is terminated between circuit breakers 1 and 2, the Q35L feeder is terminated between circuit breakers 1 and 3, the spare feeder is terminated between circuit breakers 3 and 5, and the Q35M feeder is terminated between circuit breakers 2 and 5. The GIS is expandable if a future developer were to install breaker 4 along with the requisite modifications to the existing bus section. In addition, there are a total of twelve (12) 3,000Amp motor operated disconnect switches: eighteight (8) on the ring bus with one (1) on both sides of each of the four (4) circuit breakers; one (1) each for the Q35L and Q35M feeders for two (2) in total; one (1) for the spare feeder to be terminated between breakers 3 and 5; and one (1) for the future bus in the event the GIS were to be expanded to a five (5) circuit breaker ring bus. The GIS bus has a total of four (4) Local Control Cabinets (“LCC”), one each dedicated to the control and operation of each of the GIS bus sections. The LCCs are also linked to the Remote Terminal Unit (“RTU”) system which feeds into the HMI, and the LCCs have links to the relay protection panels (first and second line). There are a total of 23 Relay protection panels, which receive their 125VDC power from their respective first and second line DC battery rooms. The relay protection panels are designed to provide protection for feeders Q35L/B47 to the Xxxx 00xx Xxxxxx and Farragut Substations and to provide protection for feeders Q35M/48 to Xxxx 00xx Xxxxxx and Farragut Substations, provide protection for the G13 Feeder, and also provide protection for the two (2), oiled filled, 150MVA, 363kV, 251 amps ASEA, Shunt Reactors. The two (2) communication rooms have Supervisory Control and Data Acquisition (“SCADA”) and RTU that integrate the Astoria Annex Substation to Con Edison’s ECC and AECC for outside control. There is also metering SCADA/RTU system that will integrate from the Astoria Annex Substation to the NYPA ECC. In the Astoria Annex Substation outdoor yard, there is one (1) Cummins 250kW, 120/208Volt, 3 Phase, 60Hz, 1800 RPM, diesel generator, with 24 hour capacity fuel tank, that provides tertiary back-up power to the Astoria Annex Substation equipment. Each feeder, Q35L and Q35M, exits the GIS building and contains three (3) ABB Gas/Air bushings, Porcelain, 362kV, which are located outside the building and are mounted on steel structures mounted to concrete foundations. Each feeder is then connected to one (1) set of a 362 kV, 3000amp, motor operated Southern States disconnect switch with a 24 pole external pipe mounted auxiliary switch. Each feeder is then connected to three (3) G&W Potheads (one for each phase), type EHC-345kV, 1300kV BL HPFF terminator for 2500 kcmil conductor cable operating at 400psi nominal pressure. Continuing beyond the Potheads, for each feeder, there is one (1) set of a 362 kV, 3000amp, motor operated Southern States disconnect switch with a 24 pole external pipe mounted auxiliary switch with three (3) surge arrestors (one for each phase), VN-245kV MCOV. Beyond the motor operated disconnect, for each feeder, is one (1) HVB three independent pole operated SF6 pneumatic circuit breaker, 362kV and 3000amps. From these outdoor circuit breakers, it connects to three (3) surge arrestors (one for each phase), VN-245kV MCOV, then each feeder ties into one (1) each ASEA, Shunt Reactors, oiled filled, 150MVA, 363kV, 251 amps. Each feeder, Q35L and Q35M, from the G&W Potheads as described in the previous paragraph, is routed underground to a new trifurcation manhole. For each feeder, there is one (1) 3 phase 6” stainless steel run for a total of 330 feet, plus one (1) 5” carbon steel oil return line 175 feet in length from the Potheads to the new trifurcation manhole. From the new trifurcation manhole to an existing NYPA trifurcation manhole, for each feeder Q35L and Q35M, there is one (1) 5” carbon steel run of 1,185 feet and one (1) 10” carbon steel run of 1,600 feet. Within the new trifurcation manholes, for each feeder, there is one (1) USi trifurcation joint and two (2) USi splice kits to connect 5,161 feet of new Okonite paper insulated cable, 345kV, 3/C 2500 kcmil. Parallel to the new transmission run, for each feeder, is 1600 feet of HDPE for the new communication run connecting to Con Edison building 136, including three (3) new communication manholes for pulling the fiber optic lines, to allow Con Edison CCTN communication to tie into the Astoria Annex Substation. In the NYPA PURS/Pumping plant yard, there is one (1) Cummins 250kW, 120/208Volt, 3 Phase, 60Hz, 1800 RPM, diesel generator (with 24 hour capacity fuel tank), that provides tertiary back-up power to the PURS/Pumping Plant equipment. The Q35L and Q35M feeders are connected via the Xxxx 00xx Xxxxxx Substation through exiting feeders B47 and 48 to the Farragut Substation. The Astoria Annex Substation, the Xxxx 00xx Xxxxxx Substation and the Farragut Substation are connected through the tele-protection system described above. By selection of CSM switch positions, various combinations of feeders/busses can be protected from at least two directions when one or more bus sections are switched out of service. First and second line protection is provided for the entire three terminal loop utilizing dedicated but physically separated tele-protection systems.
