FUNCTIONAL DESCRIPTION:

IS210TRPLH1A is a Turbine Primary Trip Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The Large Steam Turbine Primary Trip (TRPL) terminal board is used for the primary overspeed protection of large steam turbines. TRPL is controlled by the turbine Primary Turbine Protection controller (VTUR or PTUR), and contains nine magnetic relays in three voting circuits to interface with three trip solenoids (ETDs). TRPL works in conjunction with the TREL terminal board to form the primary and emergency sides of the interface to the ETDs. These two terminal boards are used in a similar way as TRPG and TREG are used on gas turbine applications. A Turbine Primary Trip Terminal Board is a component used in power generation systems, particularly in steam turbines. It is a circuit board or terminal board that is responsible for receiving and processing signals related to the primary trip system of the turbine.

FEATURES:

• Input Terminals: The primary trip terminal board has input terminals to receive signals from various sensors and devices in the turbine system. These signals can include parameters such as temperature, pressure, vibration, and flow rate, among others.

• Signal Conditioning: The board may include circuitry for signal conditioning, which helps to amplify, filter, or convert incoming signals to a suitable format for further processing.

• Relay Outputs: The primary trip terminal board typically has relay outputs that are used to send trip signals to different parts of the turbine control system. These relays can be used to initiate turbine shutdown sequences, activate alarms, or trigger other protective functions.

• Trip Logic: The board contains trip logic circuits that analyze the incoming signals and determine whether a trip condition has been met. This logic can be programmed to consider specific thresholds or combinations of signals to initiate a trip.

• Communication Interfaces: Some primary trip terminal boards may have communication interfaces, such as Ethernet, Modbus, or Profibus, to enable communication with other control and monitoring systems. This allows for remote monitoring and control of the turbine trip function.

FREQUENTLY ASKED QUESTIONS:

What is the purpose of a turbine primary trip terminal board?

The primary trip terminal board is responsible for receiving and processing signals related to the primary trip function in a turbine control system. It helps initiate turbine shutdown sequences or activate protective functions in case of abnormal conditions or emergencies.

What are the typical inputs to a primary trip terminal board?

The inputs to a primary trip terminal board can include signals from various sensors and devices in the turbine system, such as temperature sensors, pressure transducers, vibration monitors, flow meters, and more. These inputs provide information about the turbine's operating parameters.

How does a primary trip terminal board determine when to initiate a trip?

The board typically incorporates trip logic circuits that analyze the incoming signals based on pre-set thresholds or combinations. When a trip condition is met, the trip logic initiates a trip signal to shut down the turbine or activate other protective measures.
