Abstract
The article solves the problem of increasing energy efficiency in a non-traction power supply system by integrating a diesel-inertia plant of guaranteed power and a wind power plant into the power supply system of traction substations. The rationale for the efficiency of the application of diesel-inertia units on the newest block-module traction substations has been fulfilled.A scheme of diesel-inertia UGW is developed on the basis of a combined asynchronized electric machine with a different number of turns of stator windings. The proposed system of power supply for VL STP using a combined installation allows, in contrast to existing ones, to ensure the quality of voltage is required on the power supply buses of the HV SC with fluctuations and voltage cutoffs on the RU 10 kV buses of the substation, as well as for various abnormal phenomena in the RU 10 kV circles.The proposed methods for providing high-quality power supply to electric receivers, based on adaptive system control when the voltage of the network input changes before it disappears. The introduction of this power supply system of the HV STP makes it possible to compensate the reactive power of the load, is powered from the buses of the 10 kV substation, without the use of high cost static reactive power compensation equipment. The research of transient processes of UWW is carried out in the application package of modeling MATLAB & Simulink.
