FUNCTIONAL DESCRIPTION:

DS3800HSQD is a Low Horsepower Sequence Board manufactured and designed by General Electric as part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. A low horsepower sequence board (LHSB) is a type of control board used in turbine control systems to ensure the safe and efficient operation of the turbine. The LHSB is responsible for sequencing the various startup and shutdown procedures of the turbine and its associated equipment, such as pumps and valves. The term "low horsepower" refers to the fact that the LHSB is designed to control equipment with relatively low power requirements, typically less than 500 horsepower. This is in contrast to high horsepower control boards, which are used to control larger and more powerful equipment.

The LHSB typically includes a series of relays, timers, and other control devices that are used to sequence the various startup and shutdown procedures. For example, during startup, the LHSB might activate the fuel pumps, start the ignition system, and gradually open the turbine's inlet valve to bring it up to speed. During the shutdown, the LHSB might reverse these procedures, shutting down the fuel supply, shutting off the ignition, and closing the inlet valve. The LHSB is an important part of a turbine control system, as it helps to ensure the safe and efficient operation of the equipment. By carefully sequencing the startup and shutdown procedures, the LHSB can help to prevent damage to the equipment and ensure that the turbine operates at peak efficiency.

FEATURES:

A Low Horsepower Sequence Board (LHSB) is an essential component of a turbine control system. It is responsible for controlling the startup, shutdown, and operation of the turbine and its associated equipment with low power requirements. Some of the key features of an LHSB in turbine control systems include:

Sequencing: The LHSB controls the sequencing of the startup and shutdown procedures of the turbine and its associated equipment. It ensures that the equipment is started and shut down in the correct order to prevent damage and ensure efficient operation.

Safety interlocks: The LHSB includes safety interlocks that prevent unsafe or incorrect operations. These interlocks ensure that the equipment is operated within safe limits and that the equipment cannot be started or shut down in an unsafe manner.

Monitoring: The LHSB monitors various parameters, such as temperature, pressure, and speed, to ensure that the equipment is operating within safe limits. If any parameter goes outside safe limits, the LHSB will take corrective action to prevent damage to the equipment.

Alarms: The LHSB includes alarms that alert operators to any abnormal conditions or malfunctions in the equipment. The alarms can be visual, audible, or both and are designed to ensure that operators are aware of any issues that require their attention.

Remote operation: The LHSB can be operated remotely, either from a control room or from a remote location. This allows operators to monitor and control the equipment from a safe distance, reducing the risk of injury or damage.

Diagnostic tools: The LHSB includes diagnostic tools that allow operators to troubleshoot problems and identify faults in the equipment. These tools can help to reduce downtime and ensure that the equipment is operating at peak efficiency.
