Description
1. Product Title
ALSTOM SPU 232.2 (029.366 817) – Single Processor Unit for Semipol D3.1 Excitation System
2. Product Overview
The ALSTOM SPU 232.2 (029.366 817) is a single processor unit designed for the Semipol D3.1 generator excitation control system. Serving as the core processing board, SPU 232.2 (029.366 817) executes excitation regulation algorithms, processes generator voltage and current measurement signals, and governs the excitation control loop for synchronous generators. It communicates with peripheral I/O boards via CAN bus and supports closed-loop automatic voltage regulation. Built for continuous, uninterrupted operation in power plant environments, the module includes onboard hardware monitoring and fault diagnostics to detect abnormal operating conditions, supporting stable generator excitation control for thermal and combined-cycle power units.
