METHOD FOR STABILIZATION AND ADJUSTMENT OF ELECTRIC ENERGY PARAMETERS IN ELECTRIC PLANTS DIRECT CURRENT POWER SYSTEMS AND DEVICE IMPLEMENTING SAID METHOD Russian patent published in 2005 - IPC

FIELD: electric engineering.

SUBSTANCE: method for stabilization and adjustment of current value or voltage value at clamps of electric plants power systems by direct current, which provides for absence of higher harmonic curves in current, consumed from power grid, is implemented by a device, which, in accordance to method, allows to use for broadband, low-step and noncontact adjustment of value of rectified voltage great number of combinations of different operation modes of minimal number of transformer-thyristor modules. For any combination of operation modes of said modules exception of higher harmonic curves from composition of consumed electric current is automatically provided for. Use of three fully controlled electric keys (one for each phase) in device, and also systems for software control thereof with functional elements for direct and reversed fast Fourier transformations, allows to replace converting transformer with common network one in power systems for electric plants, and to decrease number of used converting transformers.

EFFECT: lower costs, lower losses, higher compatibility.
