Starlight Power is a
professional manufacturer of diesel generator sets, founded in 1974, with 64
sales and service centers in China, providing technical consulting, free
commissioning, maintenance and training services to customers. Starlight is
also the largest OEM supporting manufacturer of Cummins diesel generators in
China. Over the years, we have cooperated with Cummins, VOLVO, Perkins,
Shangchai (SDEC), Ricardo, Deutz, Weichai, Weichai Baudouin (400KW to 3000KW
heavy duty emergency diesel generators), Yuchai and other engine manufacturers
to provide the highest quality generator sets to users, which has been well
received by customers.
Starlight diesel
generators have two major characteristics: one is for emergency use, the
continuous working time is not long, generally only needs to run for a few
hours (≤ 12H); the
second is as a backup, the diesel generator is usually in a standby state, only
when the main power supply is completely failed, the diesel generator will
start to supply emergency power load. When the main power supply is restored to
normal, it will switchoff immediately. When purchasing diesel generating sets,
users should consider from the aspects of capacity, performance, and function
selection of the control system.
Determination
of capacity
The calibration capacity
of Starlight diesel generator is 12h. The capacity should be able to meet the
total calculated load of the emergency power, and it should be verified that
the generator capacity can meet the requirement of starting a single maximum-capacity
motor in the first-level load. Emergency generator generally uses three-phase
AC synchronous generator with a nominal output voltage of 400V. When there are
multiple generator sets in standby, generally only one diesel generator is set
up. Considering reliability, two gensets can also be used in parallel to supply
power.
Generally, the number of
emergency generators should not exceed 3. When multiple units are selected, the
units should try to use complete equipment with the same model, capacity,
voltage regulation and speed control characteristics, and the fuel properties
used should be the same for maintenance and common spare parts.
When there are two
generator sets for emergency use, the self-starting device should enable the
two units to be used as backup for each other, that is, after a delay in
confirmation of power failure in the mains power supply, the self-starting
command is issued. If the first unit fails to self-start for three consecutive
times, an alarm signal shall be issued and the second diesel generator shall be
started automatically.
Selection
of performance
The emergency generator
set should choose the diesel generator set with high speed, supercharging, low
fuel consumption and the same capacity. High-speed turbocharged diesel engine
has a large single-unit capacity and occupies a small space; The diesel engine
is equipped with electronic or hydraulic speed-regulating device for better
speed regulation performance; The generator should be equipped with a brushless
excitation generator or a permanent magnet generator, which has reliable
performance, low failure rate, and convenient maintenance.
Starlight provides
Stamford, Leroy-Somer, CSIC Siemens, MARATHON, Engga, Shanghai KEPU, and
Starlight and so on brushless AC generator.
When the motor capacity
is large, it is advisable to choose the third-harmonic excitation generator;
the unit is mounted on a common chassis with shock absorber; the exhaust pipe
outlet should be designed for noise reduction to reduce the impact of noise on
the surrounding environment.
