Quanchai Diesel Generator
A diesel generator is the combination of a diesel engine with an electrical generator (often
called an alternator) to generate electrical energy. Diesel generating sets are used in places
without connection to the power grid, as emergency power-supply if the grid fails, as well as
for more complex applications such as peak-lopping, Grid Support and export to the power
grid. Sizing of diesel generators is critical to avoid low-load or a shortage of power and is
complicated by modern electronics, specifically non-linear loads.
Quanchai Diesel gGenerator Sets
The packaged combination of a diesel engine, a generator and various ancillary devices
(such as base, canopy, sound attenuation, control systems, circuit breakers, jacket water
heaters and starting system) is referred to as a "generating set" or a "genset" for short.
Generator sets sizes range from 8 to 30 kW (also 8 to 30 kVA single phase) for homes, small
shops & offices with the larger industrial generators from 8 kW (11 kVA) up to 2,000 kW
(2500 kVA three phase) used for large office complexes, factories.
Supporting main utility grids
In addition to their well known role as power supplies during power failures, diesel generator
sets also routinely support main power grids worldwide in two distinct ways:
Peak lopping
Maximum demand tariffs in many areas encourage the use of diesels to come on at times of
maximum demand. In Europe this is typically on winter weekdays early evening peak when
cooking and lights are on as people come home—around 5:30–7:00 PM, whereas in the
United States this is often in the summer to meet the air conditioning load.
Grid support
Emergency standby diesel generators, for example such as those used in hospitals, water
plant, are, as a secondary function, widely used in the US and the UK (Short Term Operating
Reserve) to support the respective national grids at times for a variety of reasons.
This is extremely beneficial for both parties - the diesels have already been purchased for
other reasons; but to be reliable need to be fully load tested. Grid paralleling is a convenient
way of doing this. This method of operation is normally undertaken by a third party aggregator
who manages the operation of the generators and the interaction with the system operator.
