1000GF diesel generator set control function technical requirements

Self-initial function Diesel generator setsIt is guaranteed that it is running on the load when it is powered up in the whole plant. In the case of unattended, it is successfully initiated in 10 seconds after picking up the dynamic command, and a self-beginning cycle is implemented in 60 seconds (ie three start-up). If the start is fails three times in consecutive failure, a shutdown signal is issued and the self-start loop is locked. Under the site conditions provided by the buyer, the unit is not less than 99%. The definition of successful diesel generator sets is that the diesel generator sets in the rated speed, and the generator runs stably in the rated voltage for 2 to 3 seconds, and has Shu sub-load conditions.
1000KW diesel generator set with load stable operation function
a) After the diesel generator sets are successful, the security load is inserted.Diesel generator setsThe SHOU sub-load instruction is issued within 10 seconds after the start command is received, allowing the Shou sub-load that is not less than 50% of the rated capacity load (sensibility); load the load command again within 5 seconds after the Shou subload, allow loading to load to full load ( Sensibility) operation.
b) The diesel generator set can be operated in a rated load of 0.8, which allows for 1 hour 1.1 times overload, and within 24 hours, the overload operation is allowed to run twice. The generator allows 2 times overload operation for 20 seconds. (Overload: overcurrent under rated voltage)
c) Diesel generator sets of murine cage asynchronous motors in direct starting capacity under full-voltage.
d) When the load capacity is not less than 20%, it allows long-term stable operation.
Automatic adjustment
a) The no-load voltage tunnel of the diesel generator set is 95-105% UE.
b) Diesel generator sets should be achieved in the load of 0.8 to 1.0 with power factor, and the load power should be achieved in 0 to 100%.
Steady-state voltage adjustment rate: ≤ ± 0.5%
Steady-state frequency adjustment rate: ≤ ± 2% (solid-state electronic governor)
Voltage fluctuation rate: ≤ ± 0.15% (load power in 25-100%)
Frequency fluctuation rate: ≤0.5% (load power is increasing in 0-25%)

c)Diesel generator setsIn the no-load rated voltage, its sinusoidal voltage waveform distortion rate is not more than 3%, and the diesel generator sets at a certain three-phase proportional load, and the resistive load of 25% of the rated phase power in any of the phases should be capped. normal work. The ZUI large value (or minimum) of the generator line voltage is 5% of the three-phase line voltage average, and the temperature rise of each part of the diesel generator set does not exceed the level under the rated operating conditions.
1000KW diesel generator set control function
Diesel generator sets belong to unattended, the control system has the following functions:
a) The security segment bus voltage automatic continuous monitoring is monitored.
b) Automatic program start, distant start, manually start.
c) Automatic input function of generator space heater.
d) Automatic detection, monitoring, alarm, and protection of diesel generator sets in operation.
e) Automatic downturn, remote control, manual, and industrially manually stopped in the ground.
f) Automatic charging of the battery, with automatic internal and external switching function and battery voltage monitoring. The buyer provides a 380VAC power supply.
g) Pre-lubrication, preheating, cooling water.
