Low Hydro Grid-tied Cabinet
Typical Applications:
1. Intelligent Automatic Excitation Regulation
Adopts full digital excitation control algorithm to automatically adjust excitation current according to water turbine load changes. It stably maintains generator output voltage and suppresses voltage drift, perfectly adapting to unstable hydraulic working conditions.
2. High-precision Synchronous Grid Connection
Built-in automatic quasi-synchronization function accurately matches grid voltage, frequency and phase. It realizes smooth and impact-free grid connection to avoid surge current and protect generators and grid equipment.
3. Voltage Stabilization & Reactive Power Compensation
Supports constant voltage, constant reactive power and constant power factor operation modes. It automatically compensates unit reactive power, improves power generation quality and grid compatibility, and reduces line power loss.
4. Comprehensive Multi-level Protection
Equipped with complete protection functions including overvoltage, undervoltage, overcurrent, short circuit, loss of excitation, over-excitation, under-excitation and over-temperature protection. It provides automatic alarm and interlock shutdown to prevent equipment failure expansion.
5. Optimized for Complex Hydraulic Working Conditions
Optimized control logic for turbine start-stop fluctuation, water head change and sudden load variation. Strong anti-interference performance ensures long-term stable operation for variable-load hydropower stations.
6. Intelligent Monitoring & Remote Communication
Equipped with touch screen display for real-time monitoring of voltage, current, frequency, excitation parameters and operating status. Supports RS485 and MODBUS communication for remote monitoring, parameter debugging and data recording.
7. Highly Integrated All-in-one Design
Integrates excitation control, grid synchronization, power distribution and protection in one cabinet. Compact structure and standardized wiring simplify on-site installation and commissioning, reducing overall supporting costs for hydropower stations.
Product Overview:
The hydro generator excitation & grid connection cabinet is an integrated control and power distribution device specially designed for small and medium-sized water turbine generator sets.
