Abstract
Systems and methods provide load sharing for maintaining a stable operation of a group of electrical power generators in different load sharing scenarios. Over an interconnect bus, a controller of a gas-turbine generator (GTG) receives an indication of power generated in a set of GTGs (including the GTG) that are part of a power network, and an indication of a status change of the power network. Based on the status change and the power generated, the controller of the GTG determines whether a change in power generated by the power network is to occur and a new power level to be generated by the GTG.
Claims20
A method, comprising:
- receiving, at a controller of a gas-turbine generator (GTG), an indication of a status of another GTG over an interconnect bus;
- based on the status of the other GTG, determining, using the controller, a power level to be generated by the GTG;
- and
- driving, using the controller, the GTG to output the power level.
Non-transitory, computer-readable medium storing instructions, that when executed by one or more processors, are configured to cause the one or more processors to:
- receive, at a controller of a gas-turbine generator (GTG), an indication of power generated in a plurality of GTGs including the GTG, wherein the plurality of GTGs is part of a power network;
- receive, at the controller, an indication of a status change of a switch in the power network, wherein the status change comprises a toggle of a connection of one of the plurality of GTGs to the power network or a connection of the power network to a grid, wherein the indication is received over an interconnect bus interconnecting a plurality of controllers corresponding to the plurality of GTGs;
- based on the status of the switch and the power generated, determine, using the controller, whether a change in power generated by the power network is to occur;
- and
- drive, using the controller, the GTG based at least in part on the determination of whether to change the power generated.
A system, comprising:
- a controller comprising a memory storing instructions and a processor configured to execute the instructions to cause the processor to control power generation in a gas-turbine generator (GTG) in a power network comprising a plurality of GTGs, wherein the instructions, when executed by the processor, is configured to cause the processor to:
- receive an indication that another GTG of the plurality of GTGs is within a threshold of a maximum power generation of the other GTG, wherein the indication is received over an interconnect bus that interconnects the controllers of the plurality of GTGs;
- receive a command that the GTG is to be shut down;
- and
- based on the indication, prevent the shutdown of the GTG and send a warning to an operator.
