A. Improve the flexibility of the power supply system.

Parallel generators make it convenient for users to increase or decrease the number of generators according to the current electricity usage. When the generators need maintenance or other special circumstances, users can conveniently arrange the entire power supply system.

B. Reduce energy consumption and usage costs, and extend the service life.

For a long-term equipment such as a generator set, not only the purchase cost should be considered, but also the whole life cost should be considered. In the actual use of the parallel system, the user can choose the number of generator sets according to the size of the power consumption, saving fuel, compared with a single high-power generator, the spare parts of a small generator are easier to buy, the price is relatively cheap, and the maintenance cost is relatively low. Therefore, the life-time cost of the generator running in parallel is relatively low.

C. Improve the power supply safety of important equipment.

If one or part of the generators fails in the parallel system, reasonable arrangements can be made to allow the normal units to supply power to the particularly important loads in the system, which is impossible for a single generator.

1. Structure description

a. The frame adopts GGD cabinet, the surface is sprayed and the color is international gray.

b. The main bus bar adopts TMR copper bus bar, which is designed according to full load and is designed in the upper middle of the cabinet. The cable at the generator set end is connected from the upper end of the cabinet, and the outgoing line is connected from the upper copper bar of the outlet cabinet.

2. Technical parameters

a. The voltage of the generator set: 110~480VAC.

b. Power of a single generator set: 20KW~2400KW

c. Frequency: 50Hz/60Hz

d. Wiring mode: Y connects to three-phase four-wire.

e. Synchronization phase difference: 1~25, generally set at 100.

f. Load distribution difference: ±5% adjustable.

g. Reverse power action: 0.5~20% adjustable.

h. Positive power action:

  "NO" is adjustable from 20 to 100%.

  "OFF" is adjustable from 0 to 80%.

3. Automatic load distribution:

When the parallel operation of 2 or more units is completed, the unit starts to run with load, and the load distributor will act as an ESC to distribute the load proportionally according to the power of the unit.

4. Protective function:

   a. Synchronization protection;

   b. Reverse power protection;

   c. Over current and short circuit protection (completed by air switch);

   d. Undervoltage protection.

5. Indicating instrument:

   a. Voltmeter;

   b. Ammeter;

   c. Frequency table;

   d. Power meter;

   e. Power factor meter:

   f. Synchronization table SCM-225 (for observation in parallel).

There are closing, opening and genset operation indicators on the panel of the cabinet, and a fault alarm (acousto-optic alarm) (when there is reverse power, the unit is faulty, the acousto-optic alarm will alarm, there is manual/automatic, peak adjustment /Cut, single/parallel, master/standby selection switch.

Dingbo Power parallel cabinet can be used for 50Hz diesel generating sets.
