POWER PLANT AND ITS CONTROL METHOD Russian patent published in 2010 - IPC H02J7/35 H01L31/00 

FIELD: electricity.

SUBSTANCE: invention refers to power plants (PP) on the basis of solar cell batteries (SCB) and energy storage units, and to its control methods. PP includes SCD, DC/DC voltage converter (VC) the inputs of which are connected to SCB outputs, energy storage unit (ESU) connected to DC/DC VC outputs, and DC/AC VC the inputs of which are connected to ESU outputs, and outputs are intended for load connection; at that, five automatic switches are additionally introduced to it, and SCB, ESU and DC/DC VC are divided into two equal sections; at that, positive outputs of the first and the second SCB sections are connected through automatic switches respectively to positive inputs of the first and the second sections of DC/DC VC, the negative inputs of which are connected to negative outputs of SCB sections; positive output of the first DC/DC VC section and negative output of the second DC/DC VC section through automatic switches are connected to positive output of the first ESU section and negative output of the second ESU section, negative output of the first DC/DC VC section and positive output of the second VC section are connected to each other and through current sensor equipped with information output, and automatic switch are connected to connection point of negative output of the first ESU section and positive output of the second ESU section. Each of DC/DC VC sections is equipped with control input to which information output of current sensor is connected. PP control method involves generation of electric energy, its conversion and accumulation; at that, current sensor measures current value; the obtained value is compared to the specified one, and if the measured current value exceeds the specified one, output voltage of DC/DC VC is changed so that current value can be decreased to the specified one.

EFFECT: improving operating reliability.
