Supported Signals and Inputs
- Potential Transformer (PT) and Current Transformer (CT) Signals: The board is equipped to process PT and CT signals, which are vital for measuring voltage and current levels in power systems. These signals provide crucial insights into the electrical parameters of the system, enabling precise monitoring and control of power generation, distribution, and consumption processes.
- Contact Inputs: The board accommodates contact inputs, which serve as binary indicators of equipment status, operational states, or alarm conditions. These inputs allow the system to detect and respond to changes in the environment or equipment conditions, facilitating timely action and ensuring operational integrity and safety.
- Output Relay Drivers:Output relay drivers on the board enable the control and actuation of relay devices, which in turn control the operation of various components. These drivers provide the necessary power and signals to activate relays, facilitating the execution of control commands and automation processes.
- Pilot Trip Relay Drives: Pilot trip relay drives play a crucial role in initiating protective actions or shutdown sequences in response to abnormal conditions or fault events detected within the system. The board's support for pilot trip relay drives ensures the implementation of effective protective measures, safeguarding equipment and personnel from potential hazards.
Gate Pulse Signal Transmission
- Logic-Level Gate Pulse Signals: The board generates logic-level gate pulse signals, which serve as crucial commands for controlling power conversion processes. These signals are typically used to trigger the switching of power electronic devices such as thyristors or transistors, facilitating the regulation and conversion of electrical power within the system.
- Transmission Over the Backplane: The generated gate pulse signals are transmitted over the control backplane, which serves as a communication pathway connecting various control boards within the system. The backplane ensures efficient and reliable transmission of signals between different modules and components, enabling seamless coordination of system functions.
- Interface with ESEL Board: Upon reaching the ESEL board, the gate pulse signals are received and processed accordingly. The ESEL board serves as an intermediary interface between the control system and the power conversion cabinet, facilitating the routing and distribution of control signals to the appropriate components.
- Control of Power Conversion Processes: Once received, the gate pulse signals are further transmitted to the EGPA (Excitation Gate Pulse Amplifier) located in the power conversion cabinet. The EGPA amplifies and conditions the signals as necessary before applying them to the power electronic devices responsible for power conversion processes.
- Facilitating Power Regulation and Control: By transmitting gate pulse signals, the board enables precise control and regulation of power conversion processes within the system. This control is essential for maintaining stable and efficient operation, optimizing energy utilization, and ensuring compliance with operational requirements and safety standards.
