DEVICE FOR SYNCHRONIZATION OF THE ENERGY DISTRICT WITH THE NETWORK OF THE POWER SYSTEM Russian patent published in 2023 - IPC H02J3/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering. The PD synchronization device with the PS network contains a phase difference meter (PDF) connected to the first and second voltage meters (V) and the first and second frequency meters (FM), which are connected to the PS and PD transformers. The first adder is connected to the first FM, and the first inverter is connected to the second one, connected to the first adder connected to the first key and the module unit connected to the comparison unit connected to the first key and to the second inverter connected to the second key. The third inverter and the second adder are connected in series to the first FM, to which the second FM and the second key connected to the first and second zero-organs and the programmer are connected. The first null organ is connected to the programmer and the third key, and the second - to the programmer. A programmer and a third zero-organ connected to a third key connected to a linear switch connected to the buses and transformers of the PS and PD are connected to the PDF. The programmer and the first key are connected to the first controller associated with the second FM. Connected to the first controller are a transmitter, a receiver and a second controller connected to the first and second regulators connected to a generator connected to the PD buses.

EFFECT: increasing the accuracy of the synchronous inclusion of a power district (PD) in the grid of a power system (PS).
