METHOD TO CONTROL ONE OR SEVERAL POWER GENERATOR PLANTS Russian patent published in 2013 - IPC H02J3/46 

FIELD: electricity.

SUBSTANCE: load capacity is measured, capacity of power generators is measured, the difference of specified capacities is defined, the produced value is used to generate a signal of capacity control as a control action to change the capacity of power generator plants, control is carried out in the mode of operation in parallel with the external grid, or in the mode of operation as isolated from the grid, in the mode of operation in parallel with the grid when generating a signal of capacity control, a signal of request for disconnection of one or more loads is used, using which values of capacities of disconnected loads are subtracted from the previously determined difference, in case of equality of the grid capacity and the total capacity of disconnected loads, a control signal is generated for disconnection of requested loads, and if the capacity value from the grid is reduced below the specified value, connection of ballast resistances is carried out with subsequent smooth reduction of ballast capacity. When operating as isolated from the grid, a signal of request for loads connection is used, added capacity is determined as the value of capacities of connected loads, and a signal is generated for smooth connection of ballast resistances with the speed of not more than the specified value, in case of equality of capacities on ballast resistances and added power, ballast resistances are disconnected, and requested loads are connected.

EFFECT: increased efficiency of power generator system control.
