2.Main Features

Low harmonic performance:The PCD231B101 provides low harmonic performance without any additional filtering equipment,which makes the grid-side harmonics comply with all relevant standards.Therefore,it eliminates the need for harmonic analysis or installation of network filters and other equipment for reducing harmonics.

Active Front End(AFE):The controller has an active front end that enables regenerative braking function,so that all current flows in motor mode and generation mode.This regenerative braking function can save a lot of energy because it is able to feed energy back to the power supply network.It is particularly suitable for applications that require frequent starting and stopping,such as downhill conveyor belts or natural gas pipeline booster pumps.

Reactive(VAR)compensation function:AFE can also provide reactive compensation function,which is essential for the stable operation of the power system.

Excitation control:The PCD231B101 module is specially designed for the control of electromagnetic excitation equipment to ensure that the excitation current and voltage of the generator are maintained at appropriate levels.

Multiple control channels:The module usually has multiple control channels,which can be used to monitor and control multiple power generators at the same time.

Communication interface:PCD231B101 supports communication with other systems to achieve remote monitoring and control,so as to conveniently monitor and maintain the working status of the excitation control module.

III.System functions

System protection:Provide monitoring and protection functions for the power system to deal with abnormal conditions,thereby protecting the normal operation of the generator.

Voltage regulation:Ensure that the voltage output by the generator meets the set standards to meet the needs of the power system.

Excitation regulation:Maintain the stability of the power system by controlling the excitation current of the generator.

IV.Operation and maintenance

Precautions:Certain precautions need to be followed when operating this module,such as avoiding removing the printed circuit board(PCB)from the control cabinet unless absolutely necessary,and taking anti-static measures when replacing the PCB.

Protective grounding:Protective grounding(PE)must be connected to the back of the device to reduce the risk of electric shock.

5.Application scenarios

The PCD231B101 controller is suitable for various occasions that require efficient and stable power control,such as generator excitation systems,renewable inverters,etc.

In summary,ABB PCD231B101 is a powerful and excellent device that can meet the excitation control needs of various power systems and power generation equipment.At the same time,its low harmonic performance,regenerative braking function and reactive power compensation function also make it have a wide range of application prospects in industrial automation and control systems.
