Product Overview

The ABB 3BHE057901R0101, designated as the PC D235 C101, is a premier excitation control module within the AC800pec high-performance hardware family. This unit is specifically engineered for power electronics applications that require extremely fast control loops and high computational power. It serves as the primary processing brain for sophisticated excitation systems, managing the regulation of synchronous generators and large-scale industrial motor drives.

By combining the high-speed processing capabilities of an FPGA with the versatility of a standard industrial CPU, the AC800pec platform allows the PC D235 C101 to execute complex control algorithms with sub-microsecond latency. This makes it an indispensable component for grid-stabilizing excitation systems, high-power rectifiers, and wind turbine converters where dynamic response and precise pulse-width modulation (PWM) are critical to system integrity.

Technical Characteristics and Performance

The PC D235 C101 is designed to interface seamlessly with the broader AC800pec ecosystem, providing robust data acquisition and signal processing capabilities. It excels in transient data handling, allowing for real-time monitoring of excitation voltage and current. The module is built on a ruggedized architecture capable of operating in high electromagnetic interference (EMI) environments, typical of power plant turbine halls and heavy industrial substations.

Communication versatility is a hallmark of this module, supporting high-speed fiber-optic links for internal system coordination and standard industrial protocols for external supervisory control. This ensures that the excitation system remains fully integrated with plant-wide DCS or SCADA systems while maintaining the autonomous speed necessary for independent machinery protection.
