The purpose of the work is to develop new and improve existing methods and technical means for increasing the efficiency of electrical complexes and networks, improving the quality of electricity, diagnosing the state of electrical equipment, estimating losses from deterioration in the quality of electricity. Methods of research - the mathematical apparatus of analysis and synthesis of continuous and discrete time automatic control systems was used in the work; the theory of linear and nonlinear electric circuits; direct and inverse Fourier transform; mathematical apparatus of digital signal processing; methods of calculation of processes in switchmode converters of electric power. The reliability of the results of the calculations is confirmed by their comparison with the results of experiments. In the first chapter of the work, an original approaches, circuit decisions and control algorithms for increasing energy efficiency of inverter type welding power supplies are proposed, the original circuit solutions of such supplies, protected by patents, are proposed. In chapter 2, the performance indicators of pump units reliability is analyzed. In chapter 3, the results of research and improvement of methods for detecting damaged areas of the city distribution network with simple ground fault are given. Scope of use - electric power industry.
