Functional Description
IS200WPDFH1ACB is an optional Power Distribution Daughter Board developed by GE. It is part of the GE Speedtronic Mark VIe gas turbine control system. The board serves as a power distribution unit, designed specifically to supply power to the customer's solenoids, in conjunction with the TRLY terminal board. The daughterboard is intended to provide power to the customer's solenoids.
Product Features
- It houses two independent power distribution circuits, enabling flexible and isolated delivery of power from various standard voltage sources. Each circuit can be powered by 125 V DC, 115 V AC, or 24 V DC. Each of the two circuits supports six individually fused branches, allowing the safe distribution of power to multiple solenoid devices. The inclusion of fuses on each branch provides overcurrent protection, minimizing risk to connected components and enhancing system reliability.
- The daughterboard is designed to function in conjunction with the terminal board, forming a unified power distribution path within the control system. The fused power is routed from the daughterboard through to the terminal board�s connection points, ensuring a controlled and organized flow of current to the customer solenoids.
- The power feedback mechanism is managed by the terminal board, enabling real-time monitoring and validation of the power delivered through the fuses. This coordination contributes to safe operation, fault detection, and system diagnostics.
- As part of the overall Mark VIe control system architecture, it serves a role in field device power distribution. By offering dual power circuits, compatibility with standard voltage levels, and seamless integration with the terminal board, the board ensures stable and redundant power delivery. Its implementation supports the safe and efficient operation of turbine auxiliary systems, particularly where controlled actuation of solenoids is required.
Voltage Monitoring
- Each branch of the circuit includes a dedicated voltage monitor positioned across its fuse pair secondary. This setup allows for continuous, real-time monitoring of voltage levels within the exciter system. The voltage detectors are configured to provide feedback via three independent open-collector drivers, which interface directly with the I/O processors labeled R, S, and T. This distributed feedback system ensures that any deviations or abnormalities in voltage levels are promptly detected across all phases of operation.
- The voltage monitoring system is designed to provide rapid detection and response to changes in voltage levels. It achieves this with a maximum response delay of typically 60 milliseconds. This swift response time ensures that fluctuations in voltage, whether transient or sustained, are detected promptly, minimizing the risk of operational disruptions or equipment damage.
- The system is sensitive to subtle variations in voltage levels, capable of detecting voltages as low as 16 volts DC or 72 volts AC. This sensitivity enables the system to monitor and respond to even minor deviations in voltage, maintaining stable operation and preventing potential issues before they escalate.
- To ensure efficient operation and minimize power losses, the maximum leakage current for the voltage monitor is limited to 3 milliamperes (mA). This stringent limitation helps in preserving energy efficiency while maintaining continuous monitoring capability. By restricting leakage current, the system optimizes power consumption and enhances overall operational efficiency.
Circuit protection
- Incorporates fault current protection mechanisms to limit the flow of current within the system to levels that are within the capability of the system components. By regulating the current, this protection prevents damage to sensitive components and ensures system reliability.
- Provides feedback on the status and performance of branch circuits within the system. This feedback allows operators to monitor the health of individual circuits and identify any potential issues, such as overloads or faults.
- In systems where floating configurations are utilized, ground fault protection mechanisms are employed to detect and mitigate faults related to ground connections. This protection helps prevent electrical hazards and ensures system safety.
- Whenever feasible, redundant circuit protection schemes are implemented to enhance system reliability. Redundancy ensures that even in the event of a failure or fault in one protection mechanism, the system remains operational and protected
