How to set up solution
According to the IDC room power and business hall power demand, two 500KW diesel generator sets are used in parallel. After the parallel output of the diesel generator set, it only supplies power to the IDC equipment room and business hall.
1, the unit placement:
Since there is no room in the basement to place a diesel generator set, a silent diesel generator set is used. It is not necessary to build a diesel generator house using such a generator set. The silent diesel generator set is placed in the basement parking lot. The single unit occupies 1 parking position, and the two units occupy 2 parking spaces. The silent diesel generator set and the cabinet are placed next to the silent diesel generator set, and the cabinet adopts the bridge bus coupler, and the bridge frame is directly connected to the power distribution room and the utility power is switched.
2. Noise reduction of diesel generator sets:
The noise mute cover is used on the outside of the silent diesel generator set to process the noise of the generator set to ensure that the noise of the generator set is less than 70 decibels at 1 meter.
3. Diesel generator set fuel tank:
The silent diesel generator set uses a pedestal storage tank with a capacity of 700 liters to ensure oil consumption for a single unit for 8 hours.
4. Parallel control cabinet:
The two parallel control cabinets are placed next to the silent diesel generator set. The diesel generator set adopts the lower appearance mode, and the cabinet adopts the bottom-in and upper-out modes.
5, switch the switch cabinet:
Since the diesel generator set is used for business electricity and IDC equipment room, in order to protect the load and the effectiveness of switching between utility power and power generation, the terminal power switching mode is adopted between the backup power source and the commercial power supply, that is, in the commercial power distribution cabinet and A switchgear cabinet is set next to the IDC room power distribution cabinet.
6, power cable and bridge:
Due to the end switching mode between the backup power supply and the load, the power supply cables must be added to the commercial power distribution cabinet and the IDC equipment room power distribution cabinet after the generator unit is output. The power cable is directly connected to the load-side switching cabinet through a strong electric hoistway.
7, exhaust pipe and insulation:
Since the diesel generator set is located on the first floor of the basement, the smoke can not be discharged directly into the basement. Therefore, the exhaust pipe is exhausted from the exhaust pipe of the original basement diesel generator set. The exposed part of the exhaust pipe is wrapped with insulation material to prevent burns.
Fourth, the backup power distribution system settings
Since the floor voltage is 380V, the end switching mode between the mains and the power generation is adopted. That is, an automatic switch cabinet is installed at the floor, and a feeder cabinet is set on the power generation outlet side, and the diesel generator set is directly supplied to the floor switch cabinet after the machine is connected. The sampling of the mains signal of the diesel generator set is built in the floor distribution cabinet to improve the effectiveness of the mains sampling.
In summary, the standby power supply circuit establishes two cabinets and one feeder cabinet (5 feeder circuits are built in the cabinet: 8th floor engine room, 3rd floor UPS all the way, low voltage power distribution room all the way, two roads as backup), currently Three switchgear cabinets are set up, which are located in the 8th floor engine room, low voltage power distribution room and third floor monitoring.
Five, bank generator set purchase points
Bank procurement personnel should focus on the durability of the generator set. Boly Power recommends the selection of mid- to high-end generators such as Cummins, Volvo or Yuchai. In addition, banks should pay attention to the quiet performance of the generator set, parallel and machine room design. Huaquan generator set allows users to monitor the starting and stopping of diesel generators, oil quantity, oil pressure, current, and voltage. Regarding the Silent diesel generator set, it's from Boly Generator Factory in China.
