IS200IIDAG1A is a DC innovation board developed by General Electric. It is a part of EX2100 excitation system. It plays a pivotal role in controlling and regulating the flow of electric current in generators, ensuring that the output voltage remains consistent and within specified parameters. The core function is the precise regulation of DC (Direct Current) voltage. This is a critical aspect of the excitation system's operation. By ensuring that the generated electric field remains constant and stable, this board contributes to the consistent generation of electricity, safeguarding against voltage fluctuations and power disruptions.
- The exciter system, a central component in power generation, is a marvel of flexibility and modularity. It can be configured in various ways to cater to different requirements, offering a range of available output currents and options for system redundancy. The exciter system can draw power from potential, compound, or auxiliary sources, making it adaptable to different operational scenarios.
- The exciter system's modular nature allows for versatile assembly. Operators can configure it to meet specific power generation needs, whether it involves single or multiple bridges, warm backup bridges, or simplex and redundant control setups. This adaptability is a cornerstone of reliability in power generation, as it provides failover mechanisms and safeguards against unexpected system failures.
- The exciter system sources its power from one of two primary options. It can draw power from a potential transformer connected to the generator terminals, or it can utilize an excitation transformer connected to an auxiliary bus. These options ensure that power is consistently available, even in cases of generator terminal variations or specific auxiliary power needs.
- The exciter system relies on critical feedback mechanisms for precise control. Generator line current and stator output voltage serve as primary feedbacks to the system. These measurements are essential for monitoring and regulating the excitation process. The controlled output to the exciter field is in the form of DC voltage and current, ensuring that the electric field remains stable and consistent.
- In an era of connectivity and advanced control, the exciter system doesn't operate in isolation. It is designed to support Ethernet LAN communication with other General Electric (GE) equipment. This includes integration with the GE Control System Toolbox, which is used for configuration. Furthermore, the exciter system is a key element in communication with the broader power generation control ecosystem, including the turbine control, the LCI Static Starter, and the Human-Machine Interface (HMI) or operator interface. This interconnected architecture enhances system-wide control and monitoring capabilities.
- The exciter system includes a power conversion module (PCM) and protection circuits. The PCM is a critical component that transforms and regulates the power output to meet the generator's requirements. Protection circuits are integrated to safeguard the system against overloads, short circuits, and other potential issues, ensuring the continued safe and reliable operation of the power generation process.
- In a potential source system, the secondary of the Potential Power Transformer (PPT) is connected to a 3-phase full-wave inverting thyristor bridge. This inverting bridge is a key element that provides both positive and negative forcing voltage. The positive forcing voltage is used to optimize performance, while the negative forcing voltage allows for rapid response during load rejections and de-excitation events, ensuring system stability and efficiency.
