Photovoltaic Project Zauderas Park in the town
of Berrueco, province of Avila: 4 Plots of
100kW according to the following
DESIGN REQUERIMENTS/ASSUMPTIONS&CONSIDERATIONS:
 |
| Google Earth 40° 27' 08" N 5° 35' 07" |
· 3 Plots of 100 kW each (450 Sip
200Wp modules on fixed structures. 27 lines of 20 panels in serial) connected
to 3 Ingeteam inverters of 90.8 kW
· 1 Plot of 70 kW (435 Sip 200Wp
modules on the ground. 29 lines of 15 panels in serial) Inverter 64 kW Ingeteam
in addition to the 3 112 Apollo Solar Tracker 10 kW each (72, 90 and 90 modules Suntech If Mono 175Wp)
3 SMA Inverters of 8.8 kW.
· CC indirect contact protection:
Insulation Class II. Effective Earth Protection driven by two Relais contactors
PROAT supply opening and delayed closing to ground in case of insulation fault
added before investor. 120A 900V DC contactor closed during normal operation
and opened in case of insulation failure by earth leakage delayed 1 second max.
Inverter 900CT NINFAC PROAT NMI as / R. 27-59-81-50-RA
· TPV. 108kW, 688V + Aut.125A, 800 V +
100kW Inverter + 160A, 400V, 16kA Breaker + Leakage Current Breaker 160A, 400V,
16kA, MV.kW + Fuse.160A 300mA, 400V
· The Earthing system is TT Ground type,
so that distributor network grounding/earthing
conditions are not altered, ensuring that transfers of defects to the
distribution network will never occur.
· All masses of the PV system, both DC
and AC , metallic elements (cells, vats, boxes, etc. Lightning, surge
arresters) will be connected to a single land called Protective earth mesh
connected to an equipotential surface in
the CT (4T100KVA, 15000 / 400V) that is independent of the Service earth connected
to the neutral wire from the distribution company. Both earths should
be separated at a distance of 20 m long as no greater than 1 kV and according
MIE-RAT-ITC-RAL6 cumplimentary technical
instruction set.
· The earth of the PV system is connecting
the four inverters through a 50 mm² copper wire to connect the four PV systems.
· In the vicinity of each inverter a Copper
pike of 1.5 m has to be installed and in the vicinity of the different Command&Safety
Control Panel Boxes and three trackers. The metal parts of the (fixed and
mobile) structures and ground terminals inverters are to be also connected to
the earth system through the mesh ground assemblies of shoes armed trackers.
With this arrangement a Protective mesh is obtained.
