The menu-driven system enables operators to access and modify system settings, initiate specific functions, and monitor the drive's performance.
  • The drive continuously monitors its performance, ensuring smooth operation and fault detection. The results of this monitoring process are displayed to the operator through animated meters, icons, and digital values on the Digital Display Interface (DDI). This real-time feedback provides operators with a clear understanding of the drive's performance and operational status, allowing for timely response and intervention when necessary.
  • In addition to performance monitoring, the software also enables the operator to examine and reset any faults that may occur during operation. Through additional menus, operators can access detailed fault information, examine the root cause of the fault, and take appropriate corrective actions. The ability to reset faults through the software interface streamlines the troubleshooting process and helps to ensure uninterrupted operation of the system.

System Hardware Overview

The EX2100 hardware is housed in the following cabinets:

  • Control Cabinet: Responsible for housing the control, communication, and input/output (I/O) boards. These boards are vital for the overall operation and control of the excitation system. The control board manages and regulates various functions, including monitoring system performance, executing control algorithms, and communicating with other system components. The communication board enables seamless communication between the excitation system and other control systems or interfaces. The I/O boards facilitate the interaction between the excitation system and external devices, allowing for the exchange of signals and data.
  • Auxiliary Cabinet: Dedicated to field flashing and protection circuits, including de-excitation and shaft voltage suppression circuits. These circuits play crucial roles in ensuring safe and reliable operation of the excitation system. The field flashing circuit is responsible for providing the initial excitation current to the generator field winding during startup. Protection circuits, such as de-excitation and shaft voltage suppression, protect the generator and excitation system from potential damage due to abnormal conditions or voltage spikes.
  • Power Conversion Cabinet: Houses the silicon-controlled rectifier (SCR) cells, cooling fans, DC contactors, and an AC disconnect. The SCR cells are key components responsible for converting AC power to controlled DC power. The cooling fans are integrated into the cabinet to dissipate heat generated during operation, ensuring optimal temperature levels and preventing overheating. The DC contactors facilitate the switching and control of the DC power output, allowing for proper regulation and distribution. The AC disconnect provides a means to safely disconnect the AC power supply to the system when necessary for maintenance or emergency purposes.

De-Excitation

  • Therefore the SCR conducts and dissipates the stored energy of the generator field through the field discharge device. Feedback from either conduction sensor verifies that the discharge circuit has operated successfully. If both independent firing control circuits fail to fire, the SCR is fired by the anode firing circuit when the anode to cathode voltage has exceeded the selected level.
  • For large exciters, it is possible to connect multiple de-excitation modules together with one board configured to be the Master and the other boards configured to be Slaves.
  • As a result, the SCR conducts and dissipates the generator field's stored energy via the field discharge device. Feedback from either conduction sensor confirms that the discharge circuit worked properly.
  • If both independent firing control circuits fail to fire, the anode firing circuit fires the SCR when the anode to cathode voltage exceeds the selected level. Multiple de-excitation modules can be connected together for large exciters, with one board configured as the Master and the other boards configured as Slaves.

Control Module

  • The control module in the EX2100 system is designed as a VME-style rack, featuring multiple boards that are cable connected to the I/O terminal boards. This rack serves as the backbone of the control system, housing the essential components required for managing the motor and its associated processes. The control module's architecture provides a flexible and modular setup, allowing for efficient control and communication between various elements of the system.
  • The VME-style rack is divided into three distinct and independently powered sections, each dedicated to a specific controller within the system. These controllers are referred to as M1, M2, and C controllers:
    • M1 Controller: The M1 controller section consists of both control and I/O processor boards that handle the control functions of the motor. These boards are responsible for executing control algorithms, receiving and processing sensor inputs, and generating control signals for the motor drive. The M1 controller is a fundamental component of the system and operates independently to ensure the basic functionality of the drive.
    • M2 Controller: Similar to the M1 controller, the M2 controller section also comprises control and I/O processor boards. It serves as a backup controller, providing redundancy and additional reliability to the control system. In the event of a failure in the M1 controller section, the M2 controller can seamlessly take over and continue controlling the motor, ensuring uninterrupted operation.
    • C Controller: The C controller section is another critical element, consisting of control and I/O processor boards. Its primary role is to manage and coordinate the communication between the M1 and M2 controllers. The C controller monitors the health and status of both M controllers and facilitates the switching between them in a redundant control system setup.
  • The system's configuration determines whether it is a simplex control system or a redundant control system:
  • Simplex Control System: If the VME-style rack contains only the M1 controller section, then the control system is referred to as a simplex control system. In this setup, the M1 controller operates as the primary and sole controller for the motor. While it doesn't have the redundancy provided by the M2 controller, it remains efficient and reliable for many applications.
  • Redundant Control System: When all three controllers (M1, M2, and C) are present in the VME-style rack, the control system becomes a redundant control system. The redundant setup ensures enhanced reliability and fault tolerance. In this configuration, the C controller continuously monitors the status of both M1 and M2 controllers. If the C controller detects any issues or failures in the M1 controller, it automatically switches control to the M2 controller, ensuring continuous motor operation without interruption.
  • The redundant control system offers increased operational security and reliability, making it well-suited for critical industrial applications where uninterrupted motor operation is essential.
  • By utilizing a VME-style rack with independent controller sections and offering both simplex and redundant configurations, the EX2100 system can be tailored to meet a wide range of application needs while ensuring high-performance motor control and protection.
