What is auxiliary power supply system?
The purpose of auxiliary power supply systems is to cater for the necessary energy for the operation of primary and secondary devices at the substation. The auxiliary power systems are normally divided in two categories, namely the AC system and the DC system (s).
What are the principles used in auxiliary power supply?
Varying principles are used in the auxiliary power supply of the equipment. An important principle is to limit the distribution of the auxiliary power supply to the protection system as much as possible, and to use only one supply to the protection of an object and the breaker trip coil.
What is a minimum auxiliary power supply?
With an auxiliary power supply, it guarantees a minimum value displayed of 0.05 x In. Under this value -LL- (Low Load) is displayed. Precision is 5% ± 1 LSD (Least Significant Digit) for current values from 0.5 to 1.5 x In. 50 protection against instantane-ous or delayed short-circuit (operation on peak value).
What is auxiliary power?
This power may be provided by other units in operation during startup or may be dedicated to specific equipment, such as boilers, pumps, fans, temperature controls, and other peripheral devices. The purpose of auxiliary power is to ensure that critical systems and devices have the necessary power to function properly.
What is auxiliary power / grid power?
Auxiliary power or grid power is used to supply the peripheral devices initially to prepare the fuel cell stack ready to supply power to demands. Air pump is running 100% for 15 sec to blow off any possible water accumulation in the cathode circuit.
Does regenerative auxiliary power system save fuel?
According to their proposed method, the structure and modeling of Regenerative auxiliary power system were discussed with driving cycle; the simulation analysis shows that the usage of fuel saves up to 7%. For the future study on robust model, predictive controller has been designed for electric vehicles without predefined drive cycle.
