An integrated station brings the inverter or PCS, step-up transformer and medium-voltage equipment into a coordinated package. Define the supply boundary: a transformer, a transformer substation and a complete inverter/PCS station are different scopes.
MODEL / RATING / SCOPE
This configuration does not assign a released JIADEST model or fixed capacity range. The final transformer designation, electrical ratings, losses, impedance and documentation are confirmed in the quotation and approved technical schedule.
| Parameter | Project requirement |
|---|---|
| System scope | Identify whether inverter / PCS, transformer, MV switchgear and auxiliaries are included |
| Total rating | Define station MVA, number of converter blocks and transformer winding arrangement |
| Network | Specify MV rated voltage, insulation level, fault level and protection scheme |
| Installation | Define skid-mounted or prefabricated enclosure, footprint, access and transport limits |
| Environmental design | Specify ambient temperature, altitude, corrosion exposure and enclosure protection |
| Acceptance | Agree drawings, applicable standards, testing, interface checks and documentation |
TECHNICAL SELECTION / VERIFIED INDUSTRY EXAMPLES
Domestic series codes and international product-family names describe different design and supply scopes. Use the original manufacturer’s designation together with its application and published specification.
| Manufacturer / product | Published model / family | Rated power reference | Voltage reference | Application distinction |
|---|---|---|---|---|
| Pearl Electric · Oil-immersed compact substation ↗ | No model code stated on the cited page | 1,000–2,500 kVA | HV: 11 / 20 / 22 / 33 kV; LV: 0.4 / 0.69 kV | Integrated station reference; not a standalone transformer rating schedule. |
| Pearl Electric · Dry-type compact substation ↗ | No model code stated on the cited page | 3,000–5,000 kVA | HV: 11 / 20 / 22 / 33 kV; LV: 0.4 / 0.69 kV | Dry-type station example; converter and transformer scope must be identified. |
| CHINT · PV pad-mounted transformer ↗ | ZGS11-Z.T | Not stated in this brochure entry | Up to 40.5 kV; this is a stated voltage limit, not a voltage ratio. | Photovoltaic power-station application. Do not infer its kVA range from adjacent products. |
| Eaton · Low-voltage solar-duty transformer ↗ | Solar duty product family; individual codes depend on configuration | 15–300 kVA | 600 V voltage class; not a specified winding voltage ratio. | Bidirectional low-voltage application; not a medium-voltage BESS main step-up transformer. |
A conventional transformer connects to the inverter or PCS AC side. Battery DC connects through the PCS. Review converter harmonics, loading cycles, winding arrangement and earthing; the required design is application-specific.
Hitachi Energy · solar & BESS engineering reference ↗PV array MWp and battery MWh are not transformer apparent-power ratings. Provide inverter or PCS apparent power, AC voltages, power factor, reactive-power duty and ambient conditions when requesting a transformer.
HPS · solar-duty sizing reference ↗Provide the single-line diagram, inverter or PCS datasheet, site layout and grid connection requirements. Agree the general arrangement, winding diagram, applicable test schedule and interface responsibilities before manufacture.
