Functional Description
IS200PSCDG1ABB is a PWM power supply developed by GE. It is part of EX2100 excitation system. The Power Supply/Contactor Driver board serves critical functions within the EX2000 PWM-based exciter, providing control power, power supply sensing, and contactor control. This board receives power from the dc link via stab-on terminals DCPL1 (+) and DCPL2 (-), operating within a nominal range of 80 to 400 V dc, with transient operation up to 600 V dc during dynamic discharge.
Power Supply Functions
- Control Power Generation: The board generates control power for other control module cards. It produces +/- 24 V, +/- 15 V, and +5 V for control boards, ensuring the proper functioning of these components.
- Distribution of Power: A 17.7 V ac square wave is distributed through high-frequency transformers to power the gate driver and LAN Terminal Board (LTB) inputs.
- Auxiliary Supplies: Additionally, the board provides isolated supplies for generating 70 V dc (sufficient for powering 13 LUP inputs) and isolated SHWSHVM power for future applications.
Contractor Control Power
- Power Delivery: The contactor control power supply from the PSCD board can deliver up to 0.75 A dc. It extracts power directly from the dc link and converts it to 100 V dc via a buck converter.
- Contactor Enablement: The MDA contactor is enabled through an optically coupled signal running in parallel with the coil of Kl relay. Relay Kl is activated by the LAN and Drive Control Card (LDCC) when the control is commanded to run. Relay KS6 serves as the control's permissive to run and as an emergency stop mechanism. Dropping relay KS6 immediately halts the EX2000 PWM regulator.
Indicator LEDs
- The PS OK LED (DS29) is designed to confirm the normal operation of the power supply located on the PSCD board. When this LED is illuminated, it signifies that the power supply is functioning within acceptable parameters and operating correctly.
- The P15 LED (DS26) serves as an indicator for the P15 power supply. When lit, it confirms that this critical power source is functioning as expected, ensuring stable system operation.
- The N15 LED (DS27) provides a status update on the N15 power supply. If this LED is illuminated, it indicates that the N15 power supply is operating correctly and contributing to the overall reliability of the system.
- The N24 LED (DS28) is responsible for monitoring the N24 power supply. A lit LED signifies that the N24 power supply is functioning properly, supporting the system�s operational stability.
- The P24 LED (DS25) indicates the normal operation of the P24 power supply. When this LED is illuminated, it confirms that the P24 power supply is performing as required, ensuring the system remains fully functional without any power-related disruptions.
