Exciter Software
- The exciter software, residing within the controllers, undergoes configuration and loading procedures facilitated through the employment of the toolbox. On the interface of the toolbox, the software is visually represented by interconnected control blocks, effectively illustrating the flow of signals.
- To facilitate the control system, measurements of the generator field, stator currents, and voltages are acquired and directed into the system. During regular operation, the alternating current (AC) regulator is chosen. The generator voltages and currents, as sensed by potential transformers (PTs) and current transformers (CTs), are physically connected to the EPCT board, serving as a signal conditioning mechanism to isolate and scale these signals. Subsequently, the controller receives the conditioned signals.
- These signals are then subjected to sophisticated software conversion algorithms that facilitate the computation of system variables, thereby enabling their utilization by the regulator, limiter, and protection functions.
- The magnitude of the generator voltage and frequency are determined based on the inputs from the PTs, while the magnitude of the generator current is ascertained through the CTs. Power, denoted as P, is extracted from the generator, whereas reactive volt amperes (VARs) generated by the generator are represented as Q.
- The change in rotor speed is calculated by integrating the accelerating power, which is typically fed into the optional Power System Stabilizer (PSS).
- Active and reactive currents generated by the generator are also accounted for, alongside the magnitude of the generator flux, expressed as VHz.
- Line voltage, determined by the PTs, and line frequency, obtained through line PTs, provide crucial information for the correlation of generator and line phase angles, thereby establishing a comprehensive understanding of the system.
Control System Toolbox
- The exciter is configured and maintained using the toolbox. Control blocks and diagrams can be configured and loaded into the control system. When the exciter is turned on, the toolbox screen displays real-time data, including control system diagnostics for troubleshooting.
- The toolbox software runs on the UDH's HMI server or a separate PC. It is also possible to connect directly to the controller DSPX board via the tool port on the control rack backplane.
Control Operator Interface
- The Control Operator Interface serves as a prominent component of the control system, specifically designed to cater to situations where enhanced control capabilities are necessary. This interface is physically integrated into a panel, allowing for convenient access and visibility.
- The primary function is to provide a comprehensive display of pertinent information related to the system, while also offering precise control over various signals and parameters. By utilizing the COI, operators can effectively monitor and manage the system with greater precision and flexibility.
- To establish seamless communication between the COI and the EX2100, a robust protocol known as UDH (Universal Data Highway) is employed. This communication protocol enables direct and reliable data exchange between the COI and the EX2100, facilitating real-time monitoring and control operations.
- By leveraging the COI in conjunction with the UDH, operators gain a sophisticated means of interacting with the system, enabling them to effectively configure, adjust, and optimize system parameters following operational requirements and situational demands.
