The power plant operated three large HFO diesel generators alongside solar and grid supply without automated coordination, causing high fuel costs, manual switching delays, and no protection against reverse power export.
Deploy a 3MW automated Solar-DG-Grid synchronization system at Al-Rehman Garden P-II Power Plant to reduce fuel consumption across multiple large HFO generators and stabilize power supply.
Deploy a 3MW automated Solar-DG-Grid synchronization system at Al-Rehman Garden P-II Power Plant to reduce fuel consumption across multiple large HFO generators and stabilize power supply.
Installed a PLC-based Solar-DG synchronization controller with three Huawei inverters that prioritizes solar power and automatically manages transitions between solar, the HFO diesel generators, and grid supply, with zero-export protection and touchscreen HMI control.
The system enables parallel solar and generator operation with dynamic load sharing during grid outages, stabilizes voltage and frequency across source changes, and provides remote monitoring with instant fault alerts.
Protection and compliance controls included reverse power protection, configurable alarms, and controlled switching logic based on site conditions.
The power plant now achieves up to 60% fuel savings through optimized solar-DG integration, continuous power supply via fully automated source switching, and 24/7 remote visibility for operations staff.
Electrical SLD snapshots, HMI/SCADA views, panel documentation, and commissioning records.
