Sizing Gen-Sets: Facts, Hints, and Good Judgment 1

The complexities of today’s commercial or industrial facility, with their equipment environment of linear and nonlinear loads, places a whole new light on sizing engine-generator sets. They can supply power to a very wide range of facilities - from police stations, firehouses, and radio and TV stations to apartment buildings, hotels, and hospitals. As such, engine-generators can be seen functioning in a wide variety of ways - from providing standby and emergency power to "backing-up" the local utility during peak power demand periods....More

Full Voltage Motor Starting and Engine Generators

Engine-generators should be sized to handle the continuous kilowatt load to be supplied plus motor starting requirements and the generator losses at the number of kilowatts selected. If the acceptable level of momentary voltage dip is known, it is possible to select the size of an engine-generator so that it will be able to start given-sized motors without exceeding the specified voltage dip level. Discussion will include typical motor starting characteristics, voltage dip, NEMA Code Letters, types of alternators and their respective voltage regulation characteristics, load power factor, motor starting torque levels, and a rule-of-thumb guide for calculating motor starting effects....More

Distributed Generation: Products, Trends, and Benefits

Studies conducted by Frost & Sullivan and various investment firms have shown that Distributed Generation (DG) provides the electricity to make 50% of our paper products, 24% of our chemicals, and 30 % of our petroleum. Efficiencies are also improving rapidly. Whether you are driven by the need for additional base load, peaking power, or you are afflicted with power quality concerns, Distributed Generation is increasingly a viable solution to solve energy needs....More
