Large Scale Generator Power System Design; Synchronizing Diesel Generators & More

There are standards, regulations and statutes that control the configuration of large scale mobile generators over about a 100-kW output. Even your household standby or small business generator is subject to noise statutes. Noise is the primary culprit that controls generator construction. The other is fixed or mobile units.

Sled VS Mobile Mount Generators

All units are mounted on a frame. If the frame sets on the ground it is a sled mount. Add axles and wheels and you have a mobile mount. Many units mount the fuel tank between the side rails. A sled is delivered to the site, placed and leveled and with hookups is complete. Fuel is added; some units contain over 4,000 gallons. Sledded units are semi-permanent but can be moved if necessary. Gravel pit operations with crushers and conveyor belts is one application. Generally, a sled is place in a building or other protected area. If inside they may not have and integral enclosure, but many mounted alongside building exteriors are enclosed. Sled mounted units are the mainstay of the power utilities substations that run at peak power demand.

Synchronizing Two or More Diesel Generators

Many operators would prefer fully mobile units that can be re-situated as necessary. Long term standing however requires that tire maintenance is performed on a regular schedule. The advantage of units supplied by Environmental Power Solutions is that two units can be synced to provide for peak power usage with only one unit operating under lower demand situations. Mobility is the key in supplying power generators during a crisis. If the power goes down at a major harbor, manufacturer or emergency service like a hospitals there will be both health and economic consequences. A mobile response is vital during a crisis. Mobile units are preferred for remote construction sites where the more stationary sled mount might be preferable in mining operations.

How to Reduce Noise from Power Generators

All stationary and mobile units must comply with local noise ordinances and OSHA noise regulations. Long term exposure to higher than 85 decibels can cause hearing loss, however even long exposures to 75 decibels or less are generally considered safe. Most of these large-scale power units are enclosed to provide weather protection and to shield and attenuate the noise. Enclosure architecture also contributes to noise reduction. Placing the radiator and fans on the top will vent heat and noise upwards. Distance will reduce sound levels as well. Enclosures are generally insulated metal with venting for air circulation. The insulation not only provides thermal protection but also absorbs sound. Both the engine and generator head will require cooling. Fans can provide air circulation, as well as intake air for combustion. The insulation must protect from environmental conditions like sun, rain, cold and snow. The enclosure should reduce noise to safe levels. Insulation must be water and oil resistant. Enclosures require doors or removable panels allowing access and with interior lighting to aid in the maintenance of the genset. The primary sound attenuation is achieved via the muffler. Turbochargers absorb heat and exhaust energy also mitigating some sound, but the muffler is the final arbitrator of noise suppression.
