Description
The storage is connected on a plug-and-play principle. Factory readiness shortens construction time, the amount of work on site and the costs of unloading and transport.
The range has four sizes. The PCS-9567MV-3500 (2000–3500 kVA) and PCS-9567MV-5000 (4000 or 5000 kVA) each contain two converters in a 20-foot container weighing 19 and 24.3 t, with a 6.6–33 kV ±5 % grid. The PCS-9567MV-7000 (5000–7000 kVA) and PCS-9567MV-10000 (8000–10 000 kVA) each have four converters in a 40-foot container weighing 32.4 and 38.8 t, with an 11–33 kV ±5 % grid.
Converter efficiency is 98.5–98.7 %, the battery voltage range is 1050–1500 V, and full power is delivered at 1500 V. Operation is four-quadrant, the power factor is above 0.99, total harmonic distortion is below 3 %, and the frequency is 50/60 Hz. The transformer is oil-immersed with vector group Dy11, and for four converters with two low-voltage windings it is Dy11-y11. Cooling is ONAN or KNAN, with a temperature rise of 60 K for the oil and 65 K for the winding at 40 °C. The windings are aluminum or copper, the oil is mineral or natural ester, efficiency is per IEC or IEC Tier-2, and pressure, temperature and gas relays are fitted.
The RMU is made for 12, 24 or 36 kV and 630 A, with SF6 or non-SF6 insulation (up to 24 kV). Withstand is 20 kA/3 s, optionally 25 kA/3 s, with internal arc class IAC A FL 20 kA 1 s. On the DC side there are a disconnector and fuses, and on the AC side a motorized switch. Surge arresters of type II or I+II, insulation monitoring, smoke sensors and a 1 kVA UPS for 15 min are provided, optionally for 1 or 2 h.
The block operates at −35…+60 °C and at altitudes up to 5000 m, with ingress protection IP54 and anticorrosion versions from C4-H to C5-VH. For the grid it forms the voltage (grid forming), regulates reactive power and power factor, rides through voltage sags and surges (L/HVRT) and frequency deviations (L/HFRT), and has soft start and stop. Applications include energy time shifting, frequency regulation and peak load shaving. The manufacturer declares conformity with CE, VDE, ISO and EN.
