Power system having short circuit protection controller

摘要

A power system that supplies electrical power to at least one load is disclosed. The power system may include an electrical power generator, current sensors configured to provide current signals representative of currents output from the electrical power generator to the load, and voltage sensors configured to provide voltage signals representative of voltages output from the electrical power generator to the load. The power system may also include a controller configured to receive the current signals and the voltage signals, compare the current signals and the voltage signals to a predetermined map, determine whether a short circuit exists inside the electrical power generator based on the comparison, and send a command to turn off the electrical power generator when the short circuit exists inside the electrical power generator.

1. A power system that supplies electrical power to at least one load, the power system comprising:
an electrical power generator; current sensors configured to provide current signals representative of currents output from the electrical power generator to the load, wherein:
the electrical power generator provides the electrical power in three phases with a neutral conductor; andthe current sensors are configured to provide the current signals representative of the currents output from the electrical power generator to the load on each of the three phases and a neutral current flowing through the neutral conductor; voltage sensors configured to provide voltage signals representative of voltages output from the electrical power generator to the load; and a controller configured to:
receive the current signals and the voltage signals;compare the current signals and the voltage signals to a predetermined map;determine whether a short circuit exists inside the electrical power generator based on the comparison; andsend a command to turn off the electrical power generator when the short circuit exists inside the electrical power generator.
