FUNCTIONAL DESCRIPTION:

DS200TCPDG3BE is a Power Distribution Module manufactured and designed by General Electric as part of the Mark V LM Series used in GE Speedtronic Gas Turbine Control Systems. The Power Distribution Module (TCPD), located in the core, distributes the 125 V dc power to the TCPS boards in each I/O core, the Control Engine core, , and the TCEA boards in core. The TCPD board provides switches for powering down each core individually. The digital I/O cores ( and ) do not receive their power from the core, these cores get their power from their associated I/O core and respectively. The DTBA, DTBC, and DTBD terminal boards on the and cores get their power for the solenoids and wetted contact inputs directly from the TCPD board. The 120/240 V ac for the ignition transformers is supplied by the TCPD board. The CTBA terminal board in the core gets its 5 V power from the TCPD board.

TCPD CONNECTORS:

• J1R - Distributes the 125 V dc power to the TCPS board in the core.
• J1S - Distributes the 125 V dc power to the TCPS board in the core.
• J1T - Distributes the 125 V dc power to the TCPS board in the core.
• J1C - Distributes the 125 V dc power to the TCPS board in the core.
• J1D - Distributes the 125 V dc power to the TCPS board in the core
• J7W - Distributes the 125 V dc power to the TCTG board in the core.
• J7X - Distributes the 125 V dc power to the TCEA board in location one ,, in the core.
• J7Y - Distributes the 125 V dc power to the TCEA board in location three, , in the core.
• J7Z - Distributes the 125 V dc power to the TCEA board in location five, , in the core.
• J8A - Distributes the 125 V dc power to the DTBC board in the core for the solenoids.
• J8B - Distributes the 125 V dc power to the DTBD board in the core for the solenoids.
• J8C - Distributes the 125 V dc power to the DTBC board in the core for the solenoids.
• J8D - Distributes the 125 V dc power to the DTBD board in the core for the solenoids.
• J12A - Distributes the 125 V dc power to the DTBA board in the core for the wetted contact inputs.
• J12B - Distributes the 125 V dc power to the DTBA board in the core for the wetted contact inputs.

TCPD POWER:

External 115/230 V ac power and 125 V dc power is brought in via TB1 mounted on the core and hard-wired to the TCPD board. If ac power is provided, it is converted to the 125 V dc in a DACA (ac to DC) via the JZ2 connector. Power is distributed from to the various cores and boards via the connectors listed above. An optional JZ3 connection is available for applications requiring reduced voltages for contact #18 on the DTBC board in the core. The power distributed to the TCEA boards in the core is additionally conditioned across resistors via the JZ1 connector. If ac power is provided, the JZ5 connector provides ac power to the ignition transformer outputs.

FREQUENTLY ASKED QUESTIONS:

What are the key components of a PDM used in turbine control systems?

Typical components of a PDM in turbine control systems include relays, circuit breakers, fuses, solid-state switches, and communication interfaces. These components work together to regulate power flow, protect electrical circuits, and enable communication with other control and monitoring systems.

How does a PDM enhance the functionality of turbine control systems?

PDMs streamline the wiring layout and improve system reliability by centralizing power distribution. They allow for easier troubleshooting and maintenance by providing diagnostic capabilities and fault isolation features. Additionally, PDMs can integrate with the turbine's control network, enabling remote monitoring and control.

What are the specific safety features incorporated into PDMs for turbine control applications?

PDMs designed for turbine control applications often include features such as overcurrent protection, short-circuit protection, ground fault detection, and temperature monitoring. These safety features help prevent electrical failures and mitigate risks associated with turbine operation.
