Description
DEIF GPM5.1
Grid Protection Measurement Module | AWC 500 Wind Turbine Control Platform
Product Profile
GPM5.1 is a high-precision grid measurement and protection module developed by DEIF, designed exclusively for the AWC 500 turbine controller system. Equipped with an independent onboard processor, it directly samples three-phase grid voltage and current signals up to 690 V, computing electrical parameters locally to reduce calculation load on the main CPU. With Class 0.5 measurement accuracy covering power-related metrics, it fulfills strict grid code requirements for wind power plants. It supports real-time grid anomaly detection and protection triggering, serving as core hardware for grid compliance control of wind turbine converters.
Key Functional Highlights
- Class 0.5 high-precision measurement for voltage, current, frequency, active/reactive power and phase angle
- Supports direct connection to 690 V three-phase grid without external voltage transformers
- Embedded independent signal processing unit, offloads grid calculation tasks from main controller PCM5.1
- Built-in digital inputs and relay outputs, enabling direct threshold alarm and protection trip signal output
- Seamless data interaction via EtherCAT bus with other modules in AWC 500 rack
- Fully configurable through host application software, flexible parameter adjustment for different grid standards
- Robust EMC layout and vibration-resistant design, adapted to nacelle operation environments
- Plug-in rack structure for AWC 500 frame, convenient for maintenance and spare replacement
- Conformal coated circuit board against humidity, dust and temperature fluctuation inside turbine cabinets

Installation & Commissioning Guidelines
Cut off rack power supply before module installation. Wear anti-static protection to avoid damage to sampling circuits. Insert GPM5.1 into the designated slot of the AWC500 rack and lock firmly to guarantee stable backplane contact.
Grid voltage and current wiring must follow official terminal definitions. Separate high-voltage measurement cables from communication wires to reduce electromagnetic interference. Ensure reliable shielding grounding.
After wiring verification, power on the system. Connect configuration software to set grid protection thresholds, communication addresses and measurement parameters. Verify real-time electrical value uploading to main controller.
Carry out function simulation: test overvoltage, undervoltage, overfrequency, underfrequency and power deviation protection logic. Confirm relay alarm outputs respond accurately.
After commissioning acceptance, add regular inspection plans. Periodically check terminal tightness, module indicator status and historical fault records to maintain reliable grid monitoring.
