ABB UNITROL 1020 excitation controller modules

The ABB UNITROL 1000 excitation controller modules are designed to provide reliable and efficient excitation control for synchronous generators. Here is a detailed introduction:

General Description

The UNITROL 1000 is a compact and advanced excitation controller module developed by ABB. It is based on modern microprocessor technology, which ensures high - performance control and monitoring capabilities. This module is suitable for a wide range of synchronous generators, including those used in small - to - medium - sized power plants, industrial applications, and distributed generation systems.

Features and Functions

Control Functions

Voltage Regulation: It maintains the terminal voltage of the synchronous generator at a set value by precisely adjusting the excitation current. The controller uses a proportional - integral - derivative (PID) control algorithm to achieve accurate and stable voltage regulation, even under varying load conditions.

Reactive Power Control: The UNITROL 1000 can control the reactive power output of the generator to maintain the power factor within a specified range. This is achieved by adjusting the excitation level in response to the reactive power demand of the power system.

Automatic and Manual Modes: It offers both automatic and manual control modes. In the automatic mode, the controller adjusts the excitation based on the measured voltage and reactive power. In the manual mode, the operator can directly set the excitation current or voltage, providing flexibility for different operating scenarios.
