Doosan Portable Power How A Generator Works

Introduction

Our world revolves around energy, and at Doosan Portable Power, power and productivity are our business focuses. We specialize in building products that effectively harness and utilize power. Our mobile generators transform stored energy from diesel fuel into electricity for daily use. Let's take a closer look at how this process works.

The Generator Process

A generator engine converts diesel fuel into mechanical energy by rotating the crankshaft. When combustion occurs in each cylinder, energy is transmitted to the engine crankshaft, generating mechanical power needed for the alternator.

The Role of the Alternator

An alternator is responsible for converting mechanical power into electrical energy through a process known as magnetic induction. This process occurs when a conductive material, like copper wire, passes through a magnetic field, resulting in voltage production. If the wire is part of a complete circuit, the generated power can be transmitted effectively.

Components of the Alternator

Alternators consist of two primary components: a stator and a rotor. The stator comprises copper coils wound into the alternator's outer casing. In contrast, the rotor, which is attached to the engine crankshaft and rotates with the engine, also features wire coils wrapped around an iron core.

When voltage flows through the rotor coils, an electromagnetic field is created. As the rotor spins, this magnetic field moves across the stator's conductive wire and induces voltage. The nature of this process generates alternating current, where the voltage fluctuates between positive and negative peaks. Ideally, voltage levels should remain consistent to provide stable power, especially under load.

Automatic Voltage Regulation

To maintain consistent voltage levels, Doosan mobile generators utilize an Automatic Voltage Regulator (AVR). The AVR adjusts the magnetic fields as needed according to power demands. If there is an increase in power demand and the voltage decreases, the AVR boosts the magnetic field. Conversely, during low power demands, the AVR tempers the field to prevent overload.

Multi-Phase Alternators

Doosan mobile generators are equipped with alternators that contain six coils wound into the stator, providing three voltage sources or phases. Each phase combines two wire coils, allowing these sources to be connected either in series for high voltage applications or in parallel for low voltage needs.

To simplify wiring connections, Doosan mobile generators come with a convenient selector switch. When the operator selects the desired voltage, this switch adjusts the connections accordingly. Current then flows through a protective device known as a circuit breaker. If the current exceeds its capacity, the breaker cuts off the system, safeguarding both the generator and connected equipment from potential damage.

Once the power reaches the connection panel, operators can attach power cables to the generator's terminal board, receptacle panel, or cam lock panel. This transformation of electrical energy into light, heat, or motion provides the essential power we rely on every day.

A generator engine converts diesel fuel into mechanical energy, which then drives the alternator to convert that mechanical energy into electrical energy through magnetic induction.

2. What is the role of the alternator in a generator?
The alternator converts mechanical power from the engine into electrical energy. It consists of a stator and a rotor, where electricity is generated through the interaction of magnetic fields.

3. What is an Automatic Voltage Regulator (AVR)?
An AVR is a device that helps maintain consistent voltage levels in a generator by adjusting the magnetic fields based on power demand.

4. How do multi-phase alternators work in Doosan generators?
Doosan generators feature alternators with six coils that provide three voltage phases. These phases can be connected in series for high voltage or in parallel for low voltage, allowing for versatile application usage.

5. What safety features do Doosan mobile generators have?
Doosan mobile generators come equipped with circuit breakers that protect against overload. If the current exceeds its capacity, the breaker will disconnect the system to prevent damage.
