The Widespread Applications of Diesel Generators in Daily Life

The Widespread Applications of Diesel Generators in Daily Life

Diesel generator sets have become indispensable in modern life, providing reliable power for residential, commercial, and industrial needs. Their automated control systems consist of three key components:

1. Program Control

Executes pre-designed operational sequences using discrete on/off signals

Applies logical operations to activate commands (e.g., automatic start/stop)

Example: Automated startup during power outages

2. Analog Control

Continuously monitors operational parameters (frequency/voltage)

Compares real-time data with preset values for precision adjustment

Maintains stable output despite load fluctuations

Example: Voltage regulator maintaining 400V ±1%

3. Operational Management Control

Integrates user-defined settings with load demands

Coordinates subsystems for optimal safety and fuel efficiency

Example: Load-dependent cooling system activation

Battery Charging System

Modern diesel generators predominantly use silicon-rectifier AC generators, featuring:

1. Rotor Assembly

Function: Generates magnetic field

Components:

Exciter coils 

Claw-pole design (interlocking steel laminations)

Copper slip rings (insulated from shaft) 

Operation: Receives rectified current via carbon brushes

2. Stator Assembly

Construction: Silicon steel laminations with star-connected 3-phase windings

Output:

Neutral point at winding junction

AC output routed to diode rectifier
