Specifications

Description

IS200VTURH1BAC is a Primary Turbine Protection Board developed by GE. It is a part of Mark VI control system. The control function oversees three key overspeed trip relays situated on the terminal board. Triggered by the controller, the trip signal is relayed to TRPG before activating the emergency solenoids. The turbine's overspeed trip command may originate from either VTUR or VPR0. TRPG accommodates nine magnetic relays tasked with interfacing with three trip solenoids, referred to as Electrical Trip Devices (ETD). In TMR systems, all nine relays are engaged, whereas in simplex systems, only three are utilized.

Applications

Power Generation: This is the primary application area for this board. It monitors the speed of gas turbines and steam turbines in power plants, quickly cutting off fuel/steam supply in case of overspeed or abnormalities.

Applications: Combined Cycle Power Plants, Nuclear Power Plants, and traditional coal-fired power plants.

Oil & Gas: In long-distance pipelines or processing stations, this board is used to protect turbines driven by large machinery.

Applications: Liquefied Natural Gas (LNG) processing plants, natural gas compression stations, and large oil refineries.

Heavy Manufacturing: In some large chemical plants or paper mills, turbines are used as power sources to drive large compressors or pump sets.

Applications: Large petrochemical plants, metallurgical plants, and steel mills.

Renewable Energy: While more common in traditional energy sources, its technologies also extend to hydropower and some advanced wind power monitoring systems.

Applications: Large hydropower stations.

Operation

1 Terminal Boards: The chosen primary trip terminal board, referred to as TRPx, interfaces with the electrical trip devices (ETD) responsible for activating primary trip solenoids. TRPx contains relays specifically designed for this interface, ensuring reliable and efficient operation.

2 Emergency Trip Functionality: Typically works in conjunction with an emergency trip board (TREG) to manage both primary and emergency trip functions. This dual functionality ensures comprehensive protection against turbine malfunctions or emergencies.

3 ETD Interface: PTUR (Primary Trip Unit Relay) supports up to three electrical trip devices (ETDs) driven from each TRPx/TREx combination, allowing for flexible configuration and scalability in managing trip solenoids.

Flame Detection and Overspeed Trip Control

1 Flame Detector Monitoring: The board is responsible for monitoring eight Geiger Mueller flame detectors in gas turbine applications. These detectors are connected to the board and supplied with 335 V DC, 0.5 mA from an external power supply.

2 Overspeed Trip Relay Control: The board controls three primary overspeed trip relays on the TRPG terminal board. It generates trip signals based on turbine speed and other parameters, activating the emergency solenoids to shut down the turbine in case of an overspeed condition. This safety mechanism is crucial for preventing catastrophic failures and ensuring personnel safety.

Frequently Asked Questions

Q: What is IS200VTURH1BAC?

A: IS200VTURH1BAC is a Primary Turbine Protection Board developed by General Electric (GE) as part of the Mark VI control system series.

Q: What is the primary overspeed trip in IS200VTURH1BAC, and how is it initiated?

A: The primary overspeed trip in IS200VTURH1BAC is a critical safety function designed to prevent the turbine from exceeding safe operating speed limits. It is initiated by the main controller, which calculates the trip condition based on turbine speed and related parameters, then sends the trip signal to the IS200VTURH1BAC board for execution.

Q: What is the role of the Primary Turbine Protection Board IS200VTURH1BAC?

A: The IS200VTURH1BAC primary trip terminal board serves as an interface between the control system and the electrical trip devices. It manages the activation of primary trip solenoids through dedicated relays, ensuring fast, reliable, and accurate trip operations.

Q: How does the emergency trip functionality work with IS200VTURH1BAC?

A: The IS200VTURH1BAC board typically operates together with an emergency trip board such as TREG. This coordinated setup allows the system to handle both primary and emergency trip conditions, providing comprehensive turbine protection against overspeed, faults, or other critical failures.
