GWPC300-PVG PV Grid Connection Protection Panel

The GWPC300-PVG PV Grid Connection Protection Panel is an integrated secondary protection and control panel designed specifically for 11 kV / 33 kV /132 kV distributed PV grid connection systems. It integrates four key functions — anti-islanding protection, fault separation (interconnection protection), voltage & frequency emergency control, and power quality monitoring — into a single panel.
Installed at or near the PV grid connection point, the GWPC300-PVG provides an integrated protection, measurement & control, monitoring, and communication solution between the PV plant and the utility grid. It supports safe grid connection, reliable operation, remote supervision, and plant automation.
For distributed PV projects requiring grid connection protection + power quality monitoring + communication and data transmission in one panel, the GWPC300-PVG provides a complete integrated secondary-system solution.

GWSC-PV Solar PV SCADA Monitoring and Control System

Desc

The GWSC-PV Solar PV SCADA System is an integrated monitoring and protection platform designed for all voltage levels of solar PV grid connection, ranging from 0.4kV low-voltage distributed systems to 11kV/33kV medium-voltage collection networks and 132kV high-voltage booster stations.
Built on a hierarchical-distributed architecture, bay-level units comprise dedicated grid-interconnection protection relays and distributed bay-mounted protection devices. The system covers full-station electrical data acquisition, equipment status supervision, grid-connection safety protection, closed-loop AGC/AVC power regulation, millisecond-response primary frequency control (PFC), solar power forecasting, optional wide-band oscillation monitoring, digital fault recording & alarm, energy statistics, and utility dispatch communication. It fully complies with utility grid-access requirements for renewable energy: observable, measurable, adjustable, and controllable.
The system supports mainstream power communication protocols including IEC 60870-5-104, Modbus-TCP, and IEC 61850. It seamlessly interfaces with inverters, compact substations, combiner boxes, weather stations, energy meters, and utility dispatch master stations. It is applicable to both small-to-medium distributed and large-scale centralized PV power plants, supporting local on-site operation and remote centralized O&M. The system can also be expanded to incorporate energy storage systems (ESS) for coordinated PV-storage regulation.
