5448-906 REV:SPM-D10 synchronizer is a type of synchronizer produced by Woodward Company, based on microprocessor technology. It is specifically designed for three-phase AC generators. Here is its detailed introduction:
I. Core Functions
Automatic Matching: Achieve automatic matching of frequency, phase, and voltage to ensure stable operation of the generator during grid connection.
Protection Functions: Include over/under voltage, over/under frequency protection, phase shifting/phase vector protection, as well as generator overload, reverse power protection, etc.
Synchronization Check: Provide synchronization check as a diagnostic function and monitor the time required for the synchronization to occur accurately.
Extended Logic: Support synchronous network coupling, power-off bus control, and enable complex system integration.
Technical Specifications
Power Supply Options: Standard input is 24 Vdc, and optional input is 90–250 Vac / 120–375 Vdc.
Maximum Power Consumption: The maximum internal power consumption is 10 W.
Environmental Adaptability: Operating temperature range is -20°C to 70°C (optional models are -20°C to 60°C), capable of adapting to harsh industrial environments, with anti-vibration and electromagnetic interference resistance.
Display and Interaction: The front is equipped with an LCD text display, supporting operation information and diagnostic display; an integrated keyboard for parameter configuration.
Accuracy Class: Class 1 accuracy, ensuring high synchronization accuracy.
Isolation Protection: Not affected by grounding loop interference, enhancing system stability.
Advantages and Features
High Reliability: The microprocessor design is combined with industrial-grade components, meeting the requirements for long-term operation.
High Compatibility: Supports Woodward and other brands of speed regulators and pressure regulators, reducing system integration costs.
Comprehensive Functionality: Integrates synchronous control, load distribution, and protection functions into one, reducing the need for peripheral equipment.
Easy Operation: Parameters can be quickly set through dedicated software and configuration cables (DPC), shortening the debugging time.
Application scenario
Power transmission and distribution: Ensure the stability of frequency and voltage when the generator is connected to the grid.
Import/export control: Achieve precise synchronization in cross-border power transactions.
Generator load control: Support load balancing when multiple generators are operating in parallel.
Industrial process control: Provide a stable power supply for key equipment in industries such as chemical and metallurgy.
Isolated grid: Maintain the stable matching between generators and loads in remote areas or micro-grids.
Emergency power system: Quickly synchronize the backup generator with the mains power to ensure uninterrupted power supply to critical loads.
