Product requirements and challenges are similar to the use of diesel generators in hospitals, but banks have higher requirements for anti-interference and other environmental aspects. Therefore, they have strict requirements for the performance stability, AMF and ATS functions, instant start time, low noise, low exhaust emissions, anti-interference, safety and other aspects of diesel generators
1、 Working conditions: The unit can reliably operate under the following conditions, output power, and continuously work for 24 hours at rated power output mode (including overloading 10% every 12 hours for 1 hour) The altitude shall not exceed 1000 meters The lower limit of the ambient temperature is -15C ° C, and the upper limit is 40C ° C. Other environmental units can be selected
2、 Low work noise and low emissions
Ultra low noise, ensuring the safety of data center systems and the peace of mind of bank staff in a sufficiently quiet environment Low exhaust emissions to ensure the cleanliness of the computer room and ensure the security of computer systems and data
3、 The main and necessary protective devices of the unit can automatically detect and alarm the starting battery voltage. The unit will automatically delay shutdown in the following situations: too low, too high water temperature, too low water level, overload, starting failure, and issue corresponding signals Emergency shutdown in the following situations: overspeed, short circuit, phase loss, high voltage, voltage loss, low frequency Automatic sound and light alarm signals will be issued in the following situations: low oil pressure, high water temperature, low water level, overload, startup failure, overspeed, short circuit, phase loss, high voltage, low frequency, low starting battery voltage, high starting battery voltage, low oil level, and the alarm system of the unit has relay contacts The starting mode of the unit is selected as automatic starting mode. The crew must have AMF (Automatic Mains Failure) function and be equipped with ATS to achieve fully automatic start-up. When there is a power outage, the delay in starting time is less than or equal to; After 5 seconds (adjustable), the unit can automatically start (with a total of three consecutive automatic start functions), and the full negative switching time between mains power and the unit is less than or equal to; 10 seconds, the time required to fully meet the load input is less than 12 seconds. After the mains power is restored, the unit will maintain 0-300 seconds of operation and cool down before (adjustable) automatic shutdown Equipped with UPS power supply system
4、 By using a brushless permanent magnet excitation AC generator, it can provide high motor starting capacity and has anti-interference ability against waveform distortion of the main stator output voltage caused by nonlinear loads, which can improve the generator's ability to handle nonlinear loads. Stronger ability to withstand short-circuit current (usually up to 3 times the rated current for 10 seconds)
5、 Stable performance and strong reliability. The average fault interval of the unit shall not be less than 2000 hours In terms of technical performance, the no-load voltage setting range of the unit is 95-105% of the rated voltage When the unit supplies power to phase controlled rectifiers, switching power supplies, UPS power supplies, or other loads, low-frequency oscillations will not occur when the starting load is less than 50% of the rated value of the unit The generator can overload 1.5 times the rated current at rated voltage for 2 minutes The unit has telemetry, remote signaling, and remote control functions, which can monitor, collect, process, record, and report relevant data of the equipment locally and remotely Solution: A high-performance and stable generator set, designed with low noise and equipped with a PLC-5220 control system with AMF function. It is connected to ATS to ensure that the bank can immediately provide power in the event of a power outage from the main power supply.
