OUR PROJECTS
Agright New Zealand 3.125 MW Solar Farm Control and SCADA Systems
Integrated monitoring, control and remote access for a 3.125 MW solar farm, including DNP3 communications with Powerco’s distribution network. Delivered in collaboration with Smart Commercial Energy.
Connected Controls for Solar Farm Operation
Green Generation collaborated with Smart Commercial Energy to design, fabricate and commission SCADA and hybrid control panels for the Agright 3.125 MW solar farm in New Zealand.
The project integrated solar PV and high-voltage infrastructure into a central monitoring and control platform, with DNP3 network communications and secure remote access to support ongoing operation.
Location: New Zealand
Project Partner: Smart Commercial Energy
Network Operator: Powerco New Zealand
Services Delivered: Design, fabrication, SCADA integration and commissioning
Integrating Plant Controls and Network Communications
The brief
Deliver SCADA and hybrid control panels to connect the solar farm’s generation equipment, high-voltage infrastructure and network communications.
- 3.125 MW solar farm
- One Sungrow SG3400HV-MV inverter
- 0.6 kV low-voltage / 11 kV medium-voltage infrastructure
What We Did
Green Generation designed, fabricated and commissioned the control panels, integrating plant equipment and communications into the SCADA platform.
- Integrated solar PV and high-voltage systems
- Implemented DNP3 communications between the Sungrow inverter, SCADA system and Powerco
- Configured secure remote access for monitoring, diagnostics, data sharing and troubleshooting
The Result
A completed system providing centralised visibility and control of the solar farm’s PV and high-voltage infrastructure.
- Integrated plant monitoring and control
- Real-time generation communications with Powerco
- Remote diagnostics and operational support
Integrated Equipment for Control, Communications and Protection
The control system combines a ComAp IM1010 with Extended PLC and Modbus Client functionality, an Allen-Bradley CompactLogix 5380 PLC, and an 18.5-inch Windows-based industrial touchscreen.
Supporting equipment includes:
- Moxa MGate 5109-T for DNP3 communications
- SEL-751 relay for neutral voltage displacement (NVD) protection
- WeidmĂĽller UPS system
- 600 W inverter converting 24 V DC to 240 V AC
Centralised Control with Network and Remote Connectivity
The completed system provides centralised monitoring and control of the solar farm’s PV and high-voltage infrastructure. Network communications and remote diagnostic capabilities support ongoing plant operation.
Delivered in collaboration with Smart Commercial Energy, the project demonstrates Green Generation’s expertise in utility-scale solar controls, SCADA engineering and DNP3 integration.
