An electric generator is an integral part of a wide range of applications that supplies power to remote and urban construction locations, providing backup power in the event of a power outage. To better understand how electric generators do this, this blog will cover how they operate and the varying types available on the market. Furthermore, this will allow you to find a model that will fit your operational requirements.
Allowing companies to maintain continuous operation if the main energy goes out, electric generators transform mechanical energy into electrical energy. They produce electrical current via electromagnetic induction using a fuel source like wind, gasoline, oil, or moving water. Moreover, they operate as package units that supply electricity through a particular engine, and the engine, along with an array of other components, use a fuel source to generate usable electricity. As such, we will outline the electrical generator parts you should be familiar with.
Engine
Considered the workhorses of electric generators, the engines are usually powered by either natural gas or diesel fuel. While fuel runs the engine, the alternator and battery section convert mechanical energy into applicable electricity for various devices. Please note that the size and shape of the engine determines how much electricity the electric generator can produce.
Typically, engines used in electric generators can be either turbine engines, steam engines, reciprocating engines, or microturbines. Smaller engines generally work with gasoline, whereas larger engines run on liquid propane, natural gas, or propane gas. Even so, a very select few opt for a bi-fuel working method, meaning that they use a combination of diesel and gas.
Fuel System
The fuel system is the main section of an electric generator, so you must ensure that the appropriate fuel is being used in your system. In general, the tank reserves enough fuel to run the system for an equivalent number of hours. Meanwhile, the fuel pipe attaches the tank to the main engine, and the return pipe links the engine to the fuel source for the return of the fuel. During the process, the fuel pump transmits the fuel from the source within the fuel pipe and to the engine. Within this assembly, the filter section rids the system of any debris or contaminants in the fuel before using it in the engine, and the fuel injector grinds the fuel before sending it into the combustion chamber.
Alternator
Attached to the crankshaft of the engine with a belt, the alternator transforms the mechanical power generated by the engine into electrical output. The alternator assembly consists of a rotor and a stator; the rotor moves to make a fixed rotating electromagnetic output around the stator, while the stator is a stationary section including a set of coils that direct electricity.
Cooling, Exhaust, and Lubricating Systems
As the temperature of electric generators necessitates regulation to avoid overheating during operating, they often employ a coolant, fan, or both. Because the electric generator also generates exhaust, exhaust systems can eliminate the dangerous gasses emitted by the system as well. Furthermore, due to the array of moving parts in electric generators, ample lubrication is critical.
Control Panel
The control panel is usually based on the user interface and permits the operator to control the various electric generator parts, adjusting them as necessary. In addition, these controls are supported by various displays, gauges, switches, and buttons.
Battery Charger
Similar to other machines, electric generators are first started using a battery. That being said, the battery needs to be charged, so a battery charger should always be kept handy.
Voltage Regulator
The voltage regulator determines the voltage of the current and converts it from AC to DC, allowing operators to retrieve battery storage parts or to operate different machinery.
Main Frame/Skid
The skid or main frame houses the electric generator and its array of parts.
