INTRODUCTION (abstract of PhD thesis)
The aim of the research workis to develop of an inductive current-difference transducer with extended functionality for control and management systems.
The object of the research workare induction modifiers measuring the difference of currents for control and management systems were obtained.
The scientific novelty of the research is as follows:
new designs of an inductive current-difference transducer with extended functionality have been developed;
mathematical models of multi-contour electromagnetic circuits for an inductive current-difference transducer have been developed taking into account their aggregate and scattering parameters as well as the properties of delicate elements;
generalized mathematical models for magnetic modulation and transformer modes of a new inductive current-difference transducer have been developed;
the method of taking into account the nonlinearity of the main magnetization curve of the magnetic material of a new inductive current-difference transducer using a combination of linear elemental converters.
Implementation of research results.On the basis of new inductive large current-difference transducer for monitoring and control systems and an improved method for calculating their electromagnetic circuits:
the developed induction converter was introduced at the traction substation “Chukursoy” of the distance of power supply ECH-1- “Toshkent” of JSC “Uzbekiston Temir Yullari” (reference of JSC “Uzbekiston Temir Yullari”№01/139-21- dated January 12, 2021).
