The PCD231B/PCD231B101 3BHE025541R0101 is an excitation control module specifically designed for the control of electromagnetic excitation equipment to ensure that the excitation current and voltage of a generator are maintained at a suitable level. It usually has multiple control channels and can be used to monitor and control multiple power generators at the same time. The PCD231B101 module supports communication interfaces for data exchange and communication with other devices, control systems or monitoring systems. In addition, the module also has current and voltage monitoring functions, and can adjust the excitation current and voltage of the generator to meet the needs of the power system. At the same time, it also has protection and security functions, as well as alarm and diagnostic functions. 

The composition and function of the main circuit of the excitation device
The main circuit of the device completes the two functions of rectification and magnetic deactivation. The system uses a three-phase fully controlled bridge controlled rectifier circuit to supply DC exciting current to the rotor winding of the synchronous motor. The deactivation circuit is composed of thyristor 7.8KGZ and diode GZ in inverse parallel, in fact, it is composed of a high-power electronic switch to complete the synchronous motor in the asynchronous starting process into the starting resistance, and automatically cut off after the end of the start, to ensure that the synchronous motor in the asynchronous starting period, the rotor excitation winding neither open circuit nor short circuit. Therefore, the excitation winding can avoid overvoltage and overcurrent. 

Excitation device control part:
The control part of the system consists of S7200PLC, Pro-face touch screen and KGLF-2 microcomputer excitation controller. The PLC mainly completes the switching of the working mode of the relay circuit logic control, the P adjustment during operation and the external communication, etc. The Pro-face touch screen mainly completes the system parameter setting and the query of the information of the fault during operation, the working time and the set operation parameters. The Pro-face touch screen can view the information of the excitation current and the excitation voltage recording curve.
KGLF-2 excitation controller is composed of MC87C51 and AT89C51 microcontroller. Excitation controller mainly completes frequency measurement and excitation, pulse formation, fault detection and processing.1 Rotor induced voltage frequency measurement.
