Weak Grid Test Fixture
Simulates weak-grid conditions such as high network impedance, voltage/frequency fluctuation and three-phase imbalance to verify the grid adaptability of inverters and converters.
نظرة عامة
The weak grid test fixture is a special testing device that simulates weak-grid conditions such as high distribution-network impedance, voltage/frequency fluctuation and three-phase imbalance, verifying the grid-connected adaptability of inverters and converters. It is mainly used for pre-grid-connection compliance testing and R&D verification of new-energy equipment, and can set different ratios of short-circuit capacity to equipment capacity (SCR = 1.0–10) to reproduce a low-SCR grid environment.
التطبيقات
- Compliance testing of new-energy grid-connected equipment
