Why is DG sets are installed in Solar, Wind & Hydro plants ?
Diesel Generator (DG) sets are used in solar, wind, and hydro power plants for several important reasons, despite these being renewable energy sources. Here's a breakdown of their roles: 🔋 1. Backup Power for Auxiliary Loads Renewable plants have auxiliary systems like control rooms, monitoring equipment, inverters, cooling systems, and communication devices. DG sets provide backup power to these systems during: Grid outages Low generation periods (e.g., cloudy days for solar, low wind speeds, or dry seasons for hydro) ⚙️ 2. Black Start Capability DG sets help in black start operations, which means restarting the plant when the grid is down and no external power is available. This is especially critical for: Remote solar/wind farms Hydro plants with electronic gate controls 🛠️ 3. Commissioning and Maintenance Support During plant commissioning, before the renewable source is operational, DG se...
