METHOD OF CONTROLLING AN UNINTERRUPTIBLE POWER SUPPLY SYSTEM TO OPTIMIZE COMPONENT LIFE

摘要

A method of controlling an uninterruptible power supply system to increase component life includes decreasing a maximum output power limit of the uninterruptible power supply system when a temperature that the uninterruptible power supply system is experiencing has increased and increasing the maximum output power limit when this temperature has decreased. In an aspect, this temperature is ambient temperature of an equipment enclosure of the uninterruptible power supply system in which at least a rectifier and inverter of the uninterruptible power supply system are located. In an aspect, the method further includes upon the system going into an overload condition, determining an overload time limit based upon the temperature, the overload condition and an initial load condition. In an aspect, the method further includes upon the system going into a back-up power mode, determining a battery autonomy based upon the temperature.

1. A method of controlling an uninterruptible power supply system with a controller of the uninterruptible power supply system to improve component life, comprising:
periodically sensing a temperature that the uninterruptible power supply system is experiencing with a temperature sensor and receiving with the controller the sensed temperature from the temperature sensor; after the controller receives each periodically sensed temperature, updating with the controller a maximum power output limit of the uninterruptible power supply system based on the sensed temperature most recently received by the controller wherein if the sensed temperature has increased the maximum output power limit is decreased and if the sensed temperature has decreased the maximum power output is increased; and then controlling the uninterruptible power supply system with the controller so that a maximum power output of the uninterruptible power supply system does not exceed the updated maximum power output limit.
