System Overview

  • The system comprises a separate control simulator, which is a sophisticated system program integrated within the core software. This control simulator plays a crucial role in modeling the behavior of the field and generator, providing an accurate representation of their dynamics.
  • Within the system, the microprocessor application card plays a key role in facilitating the simulation process. Instead of utilizing real-time feedback from the field and generator, signals that mimic the behavior of these components are generated and fed into the transducing algorithms. This simulation allows for comprehensive testing and analysis without relying on actual field and generator feedback.
  • The control simulator takes into account the specific scaling requirements of the exciter for a particular generator. This ensures that the simulated signals accurately reflect the behavior of the system for that specific configuration. For example, during the start-up sequence in simulator mode, the OC2000 display on the front panel provides valuable information such as the exciter voltage and current, as well as the generator voltage for the specific generator being simulated. This information enables operators and technicians to monitor and verify the performance of the system during various stages of operation.
  • The control simulator serves multiple purposes within the system. Firstly, it acts as a training tool, allowing operators and maintenance personnel to familiarize themselves with the behavior and response of the system without the need for real-world testing. Secondly, it facilitates the startup process by providing a controlled environment to verify and fine-tune the system's calibration. Lastly, the control simulator enables comprehensive calibration verification, ensuring that the system's measurements and responses align with expected values.
  • By utilizing the control simulator as part of the system, operators and technicians can gain valuable insights, troubleshoot potential issues, and optimize the system's performance. This simulation capability enhances the overall functionality and reliability of the system, making it a valuable tool for training, calibration, and verification purposes.

Product Attributes

  • The board has been specifically designed to be used as a part of the EX2000 excitation system, which is a system that provides voltage regulation and control to generators in power plants.
  • The board is designed to detect faults and disturbances on the power lines, and to quickly respond to them or taking other appropriate actions to prevent damage.
  • In addition to its protection functions, the board is also responsible for providing real-time monitoring in the EX2000 system. This allows operators to quickly identify any issues that arise and take appropriate action to resolve them, minimizing the risk of damage to the system and preventing costly downtime.
