Method of automatically determining whether power consumption devices can be powered up in a power consuming system

A power managing system for use in a power consuming system having a first plurality of power consumption devices to be powered up by one or several voltages from a set of voltages V1, V2 . . . Vm, a second plurality of power supplies providing said set of voltages, wherein each power supply providing at least one of said set of voltages and a control point for controlling the power supplied to said first plurality of power consumption devices, said power managing system comprising:

• means for determining whether each said first plurality of power consumption devices can be powered up, including:
• (a) means for determining a first set of linear inequations linking each variable Pv1, Pv2 . . . Pvm representing the power being consumed for each of said set of voltages, or combinations of several of said variables, to predetermined power limits (PVC);
• (b) means for determining a real power value (P) requested for each voltage in order to power up each of said first plurality of power consumption devices;
• (c) means for dividing each of said real power value by the number of power supplies (p) providing power for the associated voltage in order to determine the components of a power consumption vector (PC) for each of said power supply;
• (d) means for replacing said variables Pv1, Pv2 . . . Pvm in said set of linear inequations with said corresponding components of said power consumption vector for each of said power supply to obtain a requested power value for each of said linear inequations;
• (e) means for comparing said requested power values to said predetermined power limits;
• and
• (f) means for powering up each of said first plurality of power consumption device in response to said requested power values being less than said predetermined power limits.

A computer program product, Comprising:

• a computer-readable medium having stored thereon computer executable instructions for implementing a method for determining whether power consumption devices can be powered up in a power consuming system having a first plurality of power consumption devices to be powered up by one or several voltages from a set of voltages V1, V2 . . . Vm, a second plurality of power supplies providing said set of voltages, wherein each power supply providing at least one of said set of voltages and a control point for controlling the power supplied to said first plurality of power consumption devices, said computer executable instructions when executed, perform the steps of:
• (a) determining a first set of linear inequations linking each variable Pv1, Pv2 . . . Pvm representing the power being consumed for each of said set of voltages, or combinations of several of said variables, to predetermined power limits (PVC);
• (b) determining a real power value (P) requested for each voltage in order to power up each of said first plurality of power consumption devices;
• (c) dividing each of said real power value by the number of power supplies (p) providing power for the associated voltage in order to determine the components of a power consumption vector (PC) for each of said power supply;
• (d) replacing said variables Pv1, Pv2 . . . Pvm in said set of linear inequations with said corresponding components of said power consumption vector for each of said power supply to obtain a requested power value for each of said linear inequations;
• (e) comparing said requested power values to said predetermined power limits;
• and
• (f) powering up each of said first plurality of power consumption devices in response to said requested power values being less than said predetermined power limits.
