Controllable Reactor

The article outlines the basic theory, operation principle, peculiarities of electromagnetic processes, and circuit and design solutions of a fundamentally new three-phase magnetic-valve controllable reactor, which combines increased response speed with high-precision stabilization of the current reactive power value. The advisability of a monoblock design with all power elements of the device placed in one transformer-type tank is substantiated. An example of the design of a magnetic-valve controllable transformer-type reactor for a capacity of 25 Mvar, and rated voltage of 35 kV is given along with an analysis of the effectiveness of its three-year operation as part of the Petrovsk-Zabaikalskaya 220/110/35 kV digital substation. It is shown that a reactive power source based on a new magnetic-valve controllable reactor is able---in addition to its main function of optimizing reactive power flows between power supply centers and load nodes---to normalize the voltage quality in a three-phase network with a nonlinear asymmetrical load in terms of such indicators as compensation of slow deviations of the three-phase voltage, symmetry of line-to-line voltages, and elimination of their waveform distortion.

Analytical Expressions

The aim of the paper consists in suggestion, theoretical and experimental justification of the principal workability of the electrical power amplifier proposed scheme consisting of two sequential resonant circuits with the regulated level of the electromagnetic coupling between them. Scientific novelty is determined by the formulated aim an achievement of which is based on conclusions of the theoretical analysis and experiments fulfilled for the acting model of the proposed electrical power amplifier. The base analytical expressions for the electromagnetic processes analysis in the scheme of the suggested resonant power amplifier are got. The reliability of the found analytical dependencies was shown with help of the limit passages to the according to analogs in the authoritative special publications. As the conducted experiments have shown that resonant conditions in the circuits of the suggested electrical power amplifier are fulfilling with high strictness (the frequency discrepancies are no more than ~ 0.8 %). The discrepancies between the measurement and the calculation results are quite small and can be explained by the external electromagnetic fields influence (the fields superposition of the "output" solenoid and the coupling transformer). In whole, the got results are illustrating the real possibilities of the power multiple amplifying (~35 times) in the suggested scheme of the electromagnetic resonant converter which was based on the advancement of the Tesla transformer creator ideas.
