Uninterruptible power supplies for use in a distributed network

摘要

A UPS module configured to be arranged between at least one AC line and a communications system comprising at least one load comprises a power system, a diagnostic system, and a communications module. The power system comprising a battery module, an inverter module, and a transformer module and is operatively connected between the AC line and the at least one load. The diagnostic system generates battery diagnostic information, inverter diagnostic, utility diagnostic information, and transformer diagnostic information. The communications module transfers diagnostic information between the diagnostic system and the communications system.

1. A UPS module configured to be arranged between a utility power supply supplying a utility power signal and a cable television system comprising at least one load, comprising:
a power system comprising a battery module, an inverter module, and a transformer module, where the power system is operatively connected between the utility power supply and the at least one load such that
when the utility power signal is within predetermined line parameters, the power system operates in a line mode to
supply power from the utility power supply to the at least one load through the transformer module, andsupply power from the utility power supply to the battery module through the transformer module and the inverter module, andwhen the utility power signal is not within predetermined line parameters, the power system in a standby mode to supply power from the battery module to the at least one load through the inverter module and the transformer module; a diagnostic system comprising
a battery diagnostic module configured to generate battery diagnostic information based on at least one operating characteristic of at least one element of the battery module, where the battery diagnostic information comprises
current status information indicative of performance of the battery module if the power system is operated in the standby mode when the battery diagnostic information is generated, andprojected status information indicative of projected performance of the battery module should the power system be operated in standby mode at some point in time after the diagnostic information is generated,an inverter diagnostic module configured to generate inverter diagnostic information based on at least one operating characteristic of at least one element of the inverter module, where the inverter diagnostic information is indicative of mean time between failure of the inverter module,a utility diagnostic module configured to generate utility diagnostic information based on at least one operating characteristic of at least one element of the utility power signal supplied by the utility power supply, anda transformer diagnostic module configured to generate transformer diagnostic information based on at least one operating characteristic of at least one element of the transformer module, where the transformer diagnostic information is indicative of mean time between failure of the transformer module; and a communications module operatively connected between the diagnostic module and the communications system to transfer battery diagnostic information, inverter diagnostic information, utility diagnostic information, and transformer diagnostic information between the diagnostic system and the cable television system.
