Functional Description
IS200EBRGH2ADA is an Exciter Bridge Interface Board developed by GE. It is a part of EX2100e excitation system. The EX2100e Excitation represents the culmination of meticulous hardware and software design, with a seamless integration of components and controls. The integration between Excitation Control systems, Turbine Control systems, Static Starter Control systems, Integrated Control Systems (ICS), and the Human-Machine Interface (HMI) is seamless, ensuring a cohesive solution across all components.
Control Hardware
- The control hardware options within the EX2100e Regulator system are designed with versatility in mind, offering various configurations tailored to accommodate both Thyristor and Regulator systems. Specifically, for smaller Regulator systems, there are options that utilize two pulse-width modulated (PWM) power converter modules equipped with Insulated Gate Bipolar Transistors (IGBT). These modules are capable of delivering a nominal output of up to 35 A or 120 A, depending on the configuration.
- These systems are adept at supporting a range of applications, including:
- Saturable Current Transformers / Power Potential Transformers (SCT/PPT) regulator: Providing precise control over the excitation system by regulating the voltage supplied to the field winding through SCT/PPT devices.
- Brushless exciter regulator: Offering control over the excitation system for brushless generators, ensuring optimal generator performance and stability.
- Direct current (DC) rotating exciter regulator: Regulating the output voltage of the rotating exciter in DC-based generator systems, maintaining consistent excitation levels for stable generator operation.
- By offering these configurations, the EX2100e Regulator system empowers operators with the flexibility to adapt to various generator setups and operational requirements, ensuring efficient and reliable performance across a spectrum of applications.
Digital Controller (IGBT-based Systems)
- The EX2100e Excitation control products, featuring a digital controller based on Insulated Gate Bipolar Transistor (IGBT) technology, are designed to provide precise regulation within a compact 800 mm (32 in) enclosure, supplemented by supporting hardware tailored to specific applications. While the standard enclosure size is 800 mm, alternative packaging options are also available to accommodate diverse installation needs.
- This Regulator system is versatile in its procurement options, offering the flexibility of purchasing either a fully assembled cabinet or individual components that can be shipped separately for on-site assembly, catering especially to retrofit applications where space constraints or existing infrastructure may necessitate customized solutions.
- The power conversion process within this system comprises three main sections: the input section, the DC link, and the converter output section. The input section features a robust 3-phase diode bridge equipped with input filters to ensure smooth and stable operation. It is engineered to accept a primary AC input range spanning from 90 to 280 V rms for the 35 A system, while the 120 A system can handle inputs of up to 480 V rms. Furthermore, the AC input frequency is rated at a maximum of 480 Hz, and it can be sourced from various inputs including permanent magnet generators (PMG), auxiliary buses, or directly from the generator terminals, providing versatility in system integration and compatibility with diverse power sources.
