ABB UNITROL1020 3BHE036163R6106 Synchronous Machine Excitation System

Description

Function Features

• Multiple Working Modes: It has five working modes, namely automatic voltage regulation (AVR), excitation current regulation (Manual), constant reactive power regulation (Var), constant power factor regulation (PF), and open – loop regulation (Open Loop), with automatic tracking and disturbance – free switching between modes.
• Comprehensive Limiting Functions: Include V/Hz limitation, P/Q curve limitation, on – line/off – line over – excitation limitation, low – excitation limitation, high/low voltage limitation, short – circuit strong – excitation limitation, temperature limitation, and generator current limitation.
• Monitoring and Protection Functions: It can monitor rotating diodes, and is equipped with 8 groups of programmable digital input – output ports, 4 groups of programmable output ports, 3 groups of programmable analog input ports, and 2 groups of programmable analog output ports.
• Data Recording and Communication Functions: It has data and event recording functions, and supports communication through Ethernet, USB, etc.
• Dual – Channel Function: Built – in support for dual – channel, which can be used for advanced load distribution in parallel – operating units, and the conversion between channels is automatic and disturbance – free.

Application Scenarios

• Power Generation: Suitable for small and medium – sized power plants, such as diesel – powered generators, gas – powered generators.
• Marine: Used in marine power systems, such as ship – board generators.
• Petroleum and Natural Gas: Applied in the power supply systems of oil fields, gas fields, etc.
• Mining: Can be used in the power systems of mining equipment, such as mine – used trucks and port cranes.
