How do generators start automatically?

 

Even if you've heard of automatic generator starting systems, you might not understand how they operate or why they're so important. Learn more by reading on!

When electricity is lost, an electric motor is used in automatic generator starting systems to start the engine. Automated generator starting systems are; frequently utilized by people living in high-rise buildings or isolated locations without access to power because they help keep machines functioning in an emergency.

Automatic generator starting systems: The Fundamentals.

A battery bank and a control unit are the two primary components of an automatic generator starting system. The energy produced during the regular running of the generator; is stored in a battery bank. In the event of a power loss, it also offers backup power. A control unit monitors the voltage at the battery terminals or battery bank. It immediately sends a command to the engine control unit (ECU) to engage the starter motor and switch on the ignition.

Why should the generator start on its own?

Compared to manual starters, automatic generator starters require less maintenance. It requires less work to run and maintain. In addition, because they won't burn out as rapidly as manual starts, they are safer. Last but not least, automatic starters minimize downtime by enabling the generator to work nonstop and continually.

There are two types of automatic starter systems: direct current (DC) and alternating current (AC). In DC starters, the starter motor; is powered by a battery bank. An external electrical source powers the starter motor in AC starters. When the engine starts, both types of starters will activate. However, because they are simpler to install, DC starters are more widely used.

How does an automatic starting system work with pneumatic devices?

An automatic starting system utilizes mechanical and pneumatic devices to start a generator. These systems tripped off when the generator reached a pre-determined pressure, allowing the equipment to shut down in a controlled manner. Automatic starting systems come in various ways; however, there are three standard configurations: parallel run, series-parallel, and series.

The electric starter and air compressor run parallel to the generator shaft in a parallel-run automatic starting system. The air compressor feeds air to the gas turbine starter motor when the generator is; to be started, opening the valve and allowing fuel to enter the combustion chamber. When the engine revs to its maximum level, it closes the fuel valve to stop the energy flow and activates the electric starter motor, which turns on and powers the generator.

The generator shaft runs in series with the air compressor, electric starter, and mechanical inertia flywheel in an automatic series-parallel starting arrangement. The gas turbine starter motor receives air from the air compressor when the generator is; to be activated, which causes the fuel valve to open and let fuel into the combustion chamber. When the engine revs to its maximum level, it closes the fuel valve and activates the electric starter motor, which turns on the generator and supplies it with power. Once the generator is running, the mechanical inertia flywheel keeps it going. Once the generator revs up to maximum capacity, the electric starter motor closes the fuel valve to stop fuel from flowing to the turbine.

The air compressor, electric starter, and mechanical inertia flywheel all operate in series with the generator shaft in a series automatic starting system. The air compressor feeds air to the gas turbine starter motor when the generator is; to be started, opening the fuel valve and allowing fuel to enter the combustion chamber. The electric starter motor is; turned on when the engine reaches its maximum rpm, which begins the generator and closes the fuel valve. Once the generator starts, the flywheel's mechanical inertia keeps it going. Once the generator has reached its maximum rpm, the electric starter motor closes the fuel valve, stopping fuel flow to the turbine.

How is a generator with an automatic starter operated?

To start a generator with an automatic starting system, you must acquire technical information about the generator from the manufacturer or dealer. It will include all necessary startup processes, operational guidelines, and safety precautions. Depending on its size and nature, you might be able to turn a switch into a generator by doing nothing more than turning it on.

Before trying to start a generator, be careful to understand the following information:

The use of fuel grinding (gas, diesel, propane, etc.)

Turn on the gas supply to store gasoline or diesel fuel on-site.

What sort of power output is the generator capable of producing?

What types of electrical loads will the generator be; used?

Find Out What You Need to check before starting the Generator

Look into the fuel supply. To transfer fuel from a portable tank or storage tank to the generator's fuel tank, you will require a fuel hose and gas pump if the generator runs on gasoline. To transfer diesel from a storage tank or fuel truck to the generator's fuel tank, you will require a diesel fuel pipe and transfer tank if the generator runs on diesel fuel. To calculate how much power to put into the generator, use the formula below:

Gallons of gasoline equals generator horsepower times operating hours.

For instance, a generator that continuously generates five horsepower for 12 hours would consume about 30 gallons of fuel (5 x 12 = 30).

Check the oil and coolant level. Generators have an oil reservoir; check the oil and add more if necessary. You will need a dipstick for this step.

You can see, Why do I need coolant, and what does it accomplish?

Check all electrical connections. Recheck all connections and ensure power cords are not loose or exposed within the generator's housing.

If you are using the generator for emergency power, connect the loads before starting the generator. Make sure all circuit breakers and switches are off before making any connections. Run electric power cords directly from the generator to the loads. Do not extend power lines or run a power cord into a joist or duct; this could create an electrical fault and cause damage to the generator.

Start the engine by turning the ignition switch to start. The generator engine should run smoothly. Listen for unusual noises that may indicate an imminent engine failure. If the generator engine fails to run after several tries, check the fuel, oil, and electrical connections and recheck all settings.

Warning

Do not touch the generator housing when the engine is running; parts are moving very fast, and you could be injured.

Keep fuel vapors in homes and garages well-ventilated; if exposure is prolonged, fuel fumes can cause acute illness or even death. Follow the fuel manufacturer's recommended procedures for handling and storing fuel. Always store energy outside the living area in a labeled, approved container. Never use gas cans in the kitchen or near any source of an open.
