Features

• The narrow black faceplate of the board serves as its outer casing, held together by two screws. It prominently displays essential identification markers, including the board ID and manufacturer's logo, aiding in easy recognition and traceability. Underneath the faceplate, the circuit board hosts three female terminal board strips, each offering a different number of positions: twenty, sixteen, and twenty-four respectively. These strips are meticulously labeled, clearly indicating their designated functions and purposes within the system's architecture.
• Positioned along one edge of the board, a female mating connector labeled J1 serves as a crucial interface for external connections. Additionally, a backplane connector designated as P2 is strategically placed to seamlessly plug into the rack system's backplane. This arrangement ensures robust and reliable communication between the I/O card and the broader system components.
• Centrally located on the board is a distinctive two-prong male connector identified as ECPL. This connector serves a specialized role, facilitating crucial connections and interactions vital to the system's overall functionality and integration.
• The card is equipped with an array of components meticulously arranged to optimize functionality and signal management within the excitation system. Notably, it incorporates seven relays marked as K1 through K7, pivotal in controlling and switching signals within the system. Additionally, the board features seven metal oxide varistors, multiple transistors, over 100 resistors, and 75 capacitors, each carefully selected and positioned to ensure efficient operation.
• Furthermore, the board integrates three fuses, four jumpers, and four DS (Diagnostic Socket) connections – namely Fault, Status, IPOK, and MPOK. These components and connections are critical in facilitating fault detection, system status monitoring, and diagnostic capabilities within the system architecture. The careful integration of these elements contributes to the board's robust functionality and diagnostic potential, ensuring reliable performance and effective maintenance capabilities.

Power Potential Transformer Inputs

• In the EX2100 excitation system, the power potential transformer (PPT) inputs play a crucial role in converting three-phase alternating current (AC) power into a controlled direct current (DC) output. The excitation system can receive AC power from various sources, depending on the specific requirements of the application.
• The most common source of AC power for the excitation system is a generator terminal connected Y-Delta power potential transformer. This configuration ensures that the primary and secondary voltages, as well as the kilovolt-ampere (kVA) ratings, are appropriately sized for the specific application. The Y-Delta connection allows for efficient power transfer and voltage regulation, ensuring optimal performance of the excitation system in conjunction with the generator.
• Another common source of AC power is a power potential transformer (PPT) fed by an auxiliary bus. In this setup, the excitation system receives AC power from an auxiliary bus, which can be connected to a separate power source. This configuration is often utilized in industrial applications where additional power sources are required. By using a compound source input, which combines both current and voltage inputs, the excitation system can deliver the necessary power for large motor starting and other high-demand scenarios.
• To facilitate maintenance and isolation of the AC input from the bus, the excitation system incorporates a 41AC1 device. This device acts as a switch, allowing for the isolation of the AC input when required for maintenance or troubleshooting purposes. The controls of the excitation system monitor the AC input through the EACF (Exciter Analog Control Function) board, ensuring accurate monitoring and control of the input source.
• The EX2100 excitation system is capable of receiving AC power from various sources through power potential transformer (PPT) inputs. Whether it is from a generator terminal connected Y-Delta transformer or an auxiliary bus, the excitation system is designed to efficiently convert and control the AC power to deliver the required direct current output. The inclusion of the 41AC1 device and the EACF board enables effective monitoring, isolation, and control of the AC input source for maintenance and operational purposes.

Hardware Features

The EX2100 hardware is thoughtfully distributed across three distinct cabinets, each serving specific functions to ensure the efficient operation and protection of the system. Let's expand on the purpose and components contained within each of these cabinets:

• Control Cabinet: The control cabinet plays a central role in the EX2100 system, housing critical components responsible for control, communication, and input/output (I/O) functions. It is the brain of the system, orchestrating the overall operation and performance of the drive. Some of the key components found within the control cabinet include:
  Control Boards: These boards handle the main control algorithms and logic, governing the motor operation and response to various conditions and commands.
• Communication Interface: The control cabinet includes interfaces for communication protocols that facilitate external interactions, such as connections to distributed control systems (DCS), human-machine interfaces (HMI), and other monitoring or supervisory systems.
• I/O Boards: The I/O boards handle input and output signals, providing connectivity for various external sensors, actuators, and devices. These boards enable the drive to interact with the motor and other external equipment.
• Auxiliary Cabinet: The auxiliary cabinet is dedicated to housing additional circuits and protection features that ensure the reliable and safe operation of the EX2100 system. It serves as a safeguard for various functions and includes the following components:
  Field Flashing Circuit: The field flashing circuit is responsible for providing an initial exciting current to the generator field windings during startup. This ensures that the generator can begin generating power effectively.
• De-excitation Circuit: The de-excitation circuit manages the gradual reduction of the generator field current during shutdown or fault conditions, preventing potential damage and ensuring a controlled shutdown.
• Shaft Voltage Suppression: This circuit protects the generator shaft from excessive voltages, which can arise due to electrical imbalances and pose a risk of damaging the generator bearings.
• Power Conversion Cabinet: The power conversion cabinet houses components essential for the conversion and management of electrical power. It is responsible for regulating and delivering power to the motor and includes the following components:
  Power SCR Cells: The power SCR (Silicon-Controlled Rectifier) cells are semiconductor devices that control the flow of electrical current to the motor. They enable precise and efficient control of the motor's speed and torque.
• Cooling Fans: To ensure the SCR cells and other components operate within their optimal temperature range, cooling fans are installed to dissipate heat generated during operation.
• DC Contactors: These contactors handle the switching of direct current (DC) power to the motor, enabling smooth start-up and shutdown procedures.
• AC Disconnect: The AC disconnect switch provides a means to isolate the motor from the main AC power supply during maintenance or emergency situations.
