      Key Features

      Our Static Excitation Control Systems are engineered with a comprehensive suite of features to meet modern power system demands:

      • Fully Digital Automatic Voltage Regulator (AVR): High-speed, microprocessor-based control offering exceptional accuracy, stability, and a wide range of adjustment capabilities.
      • Thyristor (SCR) Power Bridge: Robust, high-current static power converters for precise and dynamic control of the generator field current, eliminating the need for brushes and commutators.
      • Multiple Control Modes: Seamless switching between Automatic Voltage Regulation (AVR), Manual Voltage Control (FCR - Field Current Regulation), Power Factor Control (PFC), and Reactive Power Control (VAR).
      • Black Start Capability: Designed to support generator startup without an external grid source, enhancing operational flexibility for isolated grids.
      • System Redundancy (Optional): Hot-standby or dual-channel configurations for critical applications, ensuring maximum availability and uninterrupted operation.
      • Advanced Protection Features: Comprehensive monitoring and protection against over-excitation, under-excitation, field overcurrent, field overvoltage, loss of sensing, and power supply faults.
      • Intuitive Human-Machine Interface (HMI): User-friendly touchscreen display for local monitoring, control, diagnostics, event logging, and parameter configuration.
      • Extensive Communication Capabilities: Integration with plant DCS/SCADA systems via industry-standard protocols such as Modbus TCP/RTU, Profibus, IEC 61850, and Ethernet IP.
      • Built-in Diagnostics & Event Logging: Detailed fault recording and performance monitoring to simplify troubleshooting and preventative maintenance.
      • Grid Code Compliance: Designed to meet international and regional grid code requirements for voltage ride-through (LVRT/HVRT), reactive power support, and transient stability.
      • Robust & Modular Design: Industrial-grade components housed in sturdy enclosures, designed for harsh operating environments and ease of maintenance/upgrades.
      • Brushless & Brushed Exciter Compatibility: Adaptable for direct control of generator field, or as a field current source for a brushless exciter.
