Redundant power supply system

A power supply system comprising:

• at least two segregated power sections, each of the at least two segregated power sections comprising:
• a main redundancy group comprising:
• a main switch board;
• and
• at least one of:
• a power generator adapted to generate electrical power to the main switch board;
• and
• a power consumer drawing power from the main switch board;
• a bus-tie connecting the main switch boards of the main redundancy groups;
• at least two segregated directly powered thruster redundancy groups, each of the at least two segregated directly powered thruster redundancy groups being connected to and receiving AC power from one of the main switch boards through an AC interconnection;
• wherein each of the at least two segregated directly powered thruster redundancy groups comprises:
• a thruster drive connected to the main switch board of a corresponding one of the main redundancy groups, wherein the thruster drive comprises a DC/DC type breaker;
• and
• an AC/DC converter;
• wherein a number of AC interconnections to the main switch boards corresponds to a number of the at least two segregated directly powered thruster redundancy groups;
• an indirectly powered thruster redundancy group comprising a thruster drive and a thruster, and connected via a pair of DC interconnections to two of the at least two segregated directly powered thruster redundancy groups;
• wherein each of the pair of DC interconnections terminates at one of the at least two segregated directly powered redundancy groups and comprises a DC/DC type breaker for at least one of control and protection of the respective one of the pair of DC interconnections;
• wherein the indirectly powered thruster redundancy group is powered only through at least one DC interconnection of the pair of DC interconnections from at least one of the at least two segregated directly powered thruster redundancy groups;
• a power management system adapted to control and allocate power from the main switch boards respectively to the at least two segregated directly powered thruster redundancy groups and the indirectly powered thruster redundancy group;
• and
• wherein the power management system receives information related to power consumption of the indirectly powered thruster redundancy group and the at least two segregated directly powered thruster redundancy groups and to allocate power from the main redundancy groups based on the power consumption.

A power supply system comprising:

• a first segregated power section comprising a first main switch board and at least one of a first power generator configured to generate electrical power to the first main switch board and a first power consumer drawing power from the first main switch board;
• a second segregated power section comprising a second main switch board and at least one of a second power generator configured to generate electrical power to the second main switch board and a second power consumer drawing power from the second main switch board;
• a bus-tie connecting the first main switch board and the second main switch board;
• a first segregated directly powered thruster redundancy group coupled to and receiving AC power from the first main switch board through a first AC interconnection, wherein the first segregated directly powered thruster redundancy group comprises a first thruster drive connected to the first main switch board, a first AC/DC converter, and a first DC/DC type breaker;
• a second segregated directly powered thruster redundancy group coupled to and receiving AC power from the second main switch board through a second AC interconnection, wherein the second segregated directly powered thruster redundancy group comprises a second thruster drive connected to the second main switch board, a second AC/DC converter, and a second DC/DC type breaker;
• an indirectly powered thruster redundancy group comprising a thruster drive, a thruster, and an energy storage,
• wherein the indirectly powered thruster redundancy group is connected via a first DC interconnection to the first segregated directly powered thruster redundancy group and comprises a third DC/DC type breaker for at least one of control and protection of the first DC interconnection,
• wherein the indirectly powered thruster redundancy group is connected via a second DC interconnection to the second segregated directly powered thruster redundancy group and comprises a fourth DC/DC type breaker for at least one of control and protection of the second DC interconnection, and
• wherein the indirectly powered thruster redundancy group is powered only through at least one DC interconnection of the first and second DC interconnections from at least one of the first and second segregated directly powered thruster redundancy groups.
