Specification of GE 151X1235BC01SA41 Excitation board

The GE part number 151X1235BC01SA41 is manufactured by General Electric (GE).It is officially designated as a "100MM SCR HS ASSEMBLY" (Silicon-Controlled Rectifier High-Speed Assembly)and is also identified as an "Excitation board".This component is a specialized spare part designed specifically for GE gas turbines.  

In addition to its primary designations, the 151X1235BC01SA41 is also referred to as an "Editable controller", an "Analog module," or an "Input/Output Module".It serves as a direct replacement and upgraded version of the older part number 151X1215DC20SA01.This indicates that the 151X1235BC01SA41 is a modernized or improved version, designed to enhance performance or reliability while maintaining compatibility with the original system.It is specifically engineered for GE gas turbine models that utilize such components, ensuring seamless integration and functionality.  

As an excitation board and high-speed assembly, the 151X1235BC01SA41 performs several critical functions in generator and motor operations:  

Excitation Current Control: It precisely regulates the excitation current output to generators or motors by receiving external control signals and feedback. This ensures the equipment maintains stable output voltage and power under varying loads and operating conditions.  Signal Processing and Conversion: The component collects, amplifies, and filters various signals from sensors (such as voltage, current, and frequency). These signals are then converted into digital or analog formats suitable for processing by control circuits, providing accurate data for subsequent control decisions.  Protection and Monitoring: It is equipped with multiple protection features, including over-current, over-voltage, and overheating protection. Upon detecting abnormal conditions, it can quickly cut off the excitation circuit or implement other protective measures to prevent equipment damage. Additionally, it continuously monitors the real-time operational status of the excitation system, such as excitation current, voltage, and temperature, and relays this information to the higher-level control system.

Welcome to YMGK. To help you better understand 151X1235BC01SA41, The following are some case studies of the product application scenarios

Excitation control in power plants: This component is used for excitation control of generators in various types of power plants, such as thermal power generation, hydropower generation, and wind power generation. It ensures that the generator can output stable voltage and frequency to meet the requirements of grid connection and improve the efficiency and quality of power generation.

Large industrial motor drive: In the motor drive systems of large industrial equipment (such as steel rolling mills, mine hoists, large water pumps, etc.), 151X1235BC01SA41 is used to regulate the excitation current of the motor, achieving smooth speed regulation and efficient operation of the motor, thereby reducing energy consumption and extending the service life of the equipment.

Power system stability maintenance: By precisely controlling generator excitation, this component helps regulate reactive power distribution in the power system, enhance system voltage stability, and strengthen the system's ability to respond to faults and interferences, thereby maintaining the overall health and reliability of the power grid.

Furthermore, as part of the excitation system of GE Vernova EX2100e, this component is also applied in the following specific projects:

Duke Energy Edwardsport Integrated Gasification Combined Cycle (IGCC) Power Plant: GE Vernova has implemented an integrated control solution including the EX2100e excitation system in this power plant. This system has helped Duke Energy optimize efficiency, safety and emission control, ensuring the reliable operation of this clean coal-fired power plant and effectively managing the efficiency challenges brought about by the complex gasification process and outdated equipment.

Taum Sauk Hydropower Station: At this hydropower station, the installation of the EX2100e system upgraded the excitation system from a simplex configuration to a redundant configuration, significantly improving the uptime of the units and greatly reducing the risks of unit failures and power generation losses. This power station mainly supplies electricity during peak electricity consumption periods.
