WINCO – Bringing More Power

Posted on by — Leave a comment

Introducing the expanded DR line!

With improvements to our facility’s capabilities, we have expanded our diesel line by offering new Volvo powered models. This provides more power without the need of paralleling two units. The four new models provide 450kW, 500kW, 550kW, and 600kW.

The Engine

VOLVO

16L, Tier II

When designing these units, we needed a strong, dependable engine brand that could carry the load demand. Volvo has 100 years of industrial engine experience. These engines are built with prime power durability, even though the EPA doesn’t allow them for prime applications.

Features

Optional Housing
Our housing has a 77 Dba rating, the best you will find with standard housing.

LED Lighting
Standard on all housed units, automatic LED lighting makes servicing easier.

Heavy Duty Stamford PMG
The PMG allows power to the AVR to be kept near constant. This allows the AVR to quickly recover the voltage of the generator back to its nominal preset value. 

Paralleling Options

These units come with paralleling options. Paralleling allows you to quote large projects while being cost effective. The DSE8610 MKII controller represents the latest in complex load sharing & synchronizing control technology. The module has been designed to allow the operator to start, stop and synchronize the generator. If required, transfer the load to the generator either manually or automatically.

Find the right 450kW – 600kW diesel standby for your project here. You will also find spec sheets, engine information and more by going to their product pages.

As I always say “Unleash the Power”!

What is frequency regulation?

Each Winco engine driven generator set has a range of frequency regulation. Frequency is measured in Hertz (Hz). In conventional generators it is controlled by the speed (RPM) of the engine. For 60 hz applications the engine operates at 1800 or 3600 RPM depending upon the type of generator end used. It is important that the engine speed is maintained at a constant level. The engine governor maintains the engine speed.

Engine are either mechanically or electronically governed. The following animations help illustrate the differences.

MECHANICAL GOVERNOR

The mechanical governor works with weights that are connected to the flywheel. As the flywheel spins faster it will close the throttle causing the engine speed to adjust. If the flywheel speed (RPM) slows down, the weights come closer to the shaft causing the throttle to open.

ELECTRONIC GOVERNOR

The electronic governor have a mag pickup that monitors the speed of the flywheel by registering an electrical signal when raised teeth pass close by it. The mag pick up signal is sent to the electronic throttle control which opens or closes the throttle to adjust the engine speed.

Which type of frequency regulation is better? It really depends on what you need. Check out our clean power article to learn more.

What Controls Voltage Regulation?

Proper voltage output protects the generator and anything it is powering.

WINCO specifies voltage regulation on all of our spec sheets. This voltage regulation is steady state, meaning it has a fixed load and accounts for bigger variations during motor starting and other large loading situations.

Expected ranges:

  • +/- 1% for both 120 and 240V (AVR)
  • +/- 5% for both 120 and 240V (Capacitor)

VOTAGE REGLATORS

Automatic Voltage Regulator

An AVR electronically regulates voltage, usually less than 1%, providing a more constant and reliable power supply. The AVR constantly adjusts the strength of the rotor field to control the output voltage.

Capacitor Voltage Regulator

Capacitors are used in brushless rotating field generator designs. They are an inexpensive way to regulate voltage while eliminating brushes and slip rings.

Transformer Voltage Regulator

In transformer machines the amount of current draw on the generator alters the strength of the field adjusting voltage. Transformer regulated machines generally have superior motor starting characteristics.

When an AVR is combined with an engine equipped with an electronic governor, you will achieve the most accurate regulation. Whereas, a mechanical governor with an inherently regulated system will have the least accurate voltage regulation. You can learn more about engine governors here.

While you are looking at the right generator for your application, make sure you have verified what range of voltage your equipment requires.

What is Total Harmonic Distortion?

AC voltage follows a sine wave. A perfect sine wave is shown below on the left. The position of the winding groups and other factors in the generator end determines the generator’s output voltage sine wave. Since the generator end is not prefect there are variations in a mechanically produced since wave from “perfect.” This variation is called Total Harmonic Distortion or THD.

Perfect Sine Wave

Variant Sine Wave

The diagrams above show a perfect sine wave (left) without any THD, and a sine wave with variations (right). All of Winco’s current product offering has THD of less than 6%. This is suitable for most applications.

WINCO Has Struck Oil!

Posted on by — Leave a comment

We have partnered with a nationally recognized oil company (we can’t say who because it normally costs more) to give you a high quality, WINCO branded, full synthetic oil. This is the same oil we put in each engine at the factory allowing you to continue using the oil we trust to keep everything running smoothly.

5W-30

Part number: 300515-31
MSRP: $12.00/quart

5W-40

Part number: 300515-425
MSRP: $71.00/2.5 gallons

When you add on a maintenance kit to your generator purchase, don’t forget the oil!
