Abstract
A command and control system and method for multiple turbogenerators in a grid parallel system includes a master controller to start, sequence, coordinate power commands, and provide fault handling to each of the individual turbogenerators and the specific control modes. A bidirectional power meter, that measures the load consumption (or production when a turbogenerator system is installed) in a building or application, may also be utilized. This power meter can provide a reference or setpoint to the master controller for controlling the individual turbogenerators.
Claims28
A command and control system for a plurality of turbogenerators, comprising:
- a plurality of individual turbogenerators, each of said plurality of individual turbogenerators having a controller;
- a command and control system bus, each of said plurality of individual turbogenerator controllers operably connected to said command and control system bus;
- a plurality of disconnect switches, a disconnect switch provided in each operable connection of an individual turbogenerator controller to said command and control bus;
- a bidirectional power meter;
- a master controller operably associated with each of the turbogenerator controllers and with said bi-directional power meter to control operational sequencing of the individual turbogenerators in a selected control mode;
- and
- a junction box operably connecting an electric utility, said power meter, the output of the plurality of individual turbogenerators, and a load,
- wherein said operational sequencing includes the starting stopping and loading of each of said plurality of individual turbogenerators, and
- wherein a turbogenerator is automatically restarted in the event of a fault shutdown.
A control system for a plurality of turbogenerators, comprising:
- a plurality of turbogenerators, each of said plurality of individual turbogenerators having a controller;
- a control system bus, each of said plurality of turbogenerator controllers operably connected to said control system bus;
- a switch provided in each operable connection of an individual turbogenerator controller to said control bus;
- a power meter;
- a master controller operably associated with each of the turbogenerator controllers and with the power meter to control the operational sequences for the individual turbogenerators in a selected control mode;
- and
- a junction box operably connecting an electric utility, said power meter, the output of the plurality of individual turbogenerators, and a load,
- wherein the operational sequences include a start sequence, a stop sequence and a load sequence, and
- wherein a turbogenerator is automatically restarted in the event of a fault shutdown.
