Abstract
A turbomachine complex includes at least one motor-generator, at least one power source coupled to the at least one motor-generator, and at least one load dissipative device coupled to the at least one motor-generator. The turbomachine complex is configured to energize the at least one motor-generator through the at least one power source. The turbomachine complex is further configured to simultaneously energize the at least one at least one load dissipative device through the at least one motor-generator.

A turbomachine complex comprising:
- at least one motor-generator;
- at least one power source coupled to said at least one motor-generator;
- at least one load dissipative device coupled to said at least one motor-generator, said turbomachine complex configured to energize said at least one motor-generator through said at least one power source, said turbomachine complex further configured to simultaneously energize said at least one load dissipative device through said at least one motor-generator;
- at least one first switch complex coupled to and between said at least one load dissipative device and said at least one motor-generator, said at least one first switch complex comprises at least one first switch, at least one first measuring device coupled to at least one of said turbomachine complex and said at least one power source, and at least one first controller coupled to and between said at least one first switch and said at least one first measuring device, wherein said first switch is configured to alternately open and close to facilitate a first regulated electrical power flow from said at least one motor-generator to said at least one load dissipative device:
- and
- at least one second switch complex coupled to and between said at least one power source and said at least one motor-generator, said at least one second switch complex comprises at least one second switch, at least one second measuring device coupled to at least one of said turbomachine complex and said at least one load dissipative device, and at least one second controller coupled to and between said at least one second switch and said at least one second measuring device, wherein said second switch is configured to alternately open and close to facilitate a second regulated electrical power flow from said at least one power source to said at least one motor-generator.

- alternately transitioning to and from each of said at least two operational states based on at least one result of determining the present operational state;
- coupling at least one first switch complex to and between said at least one load dissipative device and said at least one motor-generator, the first switch complex including at least one first switch, at least one first measuring device, at least one first computer-readable media, and at least one first controller;
- coupling at least one second switch complex to and between said at least one power source and said at least one motor-generator, the second switch complex including at least one second switch, at least one second measuring device, at least one second computer-readable media, and at least one second controller;
- and
- receiving at least one user-defined value of at least one first set point and at least one second set point, said at least one user-defined value including a value of at least one of a power, a current, a voltage, a resistance, a frequency, a phase, and an impedance associated with at least one of said at least one power source and said at least one load dissipative device.
