Patent analysis of the digital synchronous motor excitation regulator

A significant part of the devices at enterprises has been in operation since the eighties of the last century. A thyristor exciter is a system designed to control and stabilize the operating processes of engines that are part of devices operating at high speed. The efficiency of operation of such machines as compressors, fans, pumps directly depend on how high-quality exciters are installed in their design. Thyristor exciters are also designed for the generation of low-power hydro and turbo generators, synchronous motors and compensators. In order to increase reliability and ensure uninterrupted operation of a synchronous electric drive with optimal electrical performance, it is necessary to use high speed thyristor exciters, in our case, the digital excitation regulator of a synchronous motor - ANICRON. In comparison with electric machine exciters, thyristor ones require three times less maintenance costs. The improvement of the technical and economic indicators of a synchronous electric drive is carried out by reducing losses in power lines, increasing the reliability of the power electric drive, and additional capabilities of a thyristor-exciter device. To date, the effectiveness of such pathogens has been evaluated by enterprises in the sugar, chemical, energy and other industrial fields. Thyristors are widely used not only in the Russian Federation, but also abroad.
