Abstract Compressor station (CS) is an essential and an integral part of gas pipeline, providing gastransportation by means of power equipment, installed at CS. It serves as a control element in thecomplex of buildings, belonging to the trunk gas pipeline. It is by compressor station operationparameters the pipeline operation mode is defined. Presence of CS allows to adjust an operation modeof the gas pipeline at gas consumption fluctuations, using the maximum of the gas pipeline storagecapacity.During the operation of compressor station there can occur some infractions of gas pumping unit(GPU) electro-receivers power supply, leading to a forced or emergency stop of at least one GPU ofCS. Wind power plants can be used as a backup power supply. Years of national and internationalexperience show that the use of wind power plants of low power (up to 5-6 kW) is almost alwayseconomically feasible in areas with average annual wind speed VAV. AN. of more than 3.5-4.0 m/s. Theuse of high-power wind power plants is justified in cases when VAV. AN. exceeds 5.5-6.0 m/s.In the master's thesis the possibility of wind power plants exploitation for uninterrupted operation ofauxiliary power plant (APP), which is a part of compressor station, is considered.In the first chapter of the thesis the condition and reliability of CS power supply system of trunk gaspipelines (TGP) is examined. Besides the issues of energy supply and gas facilities stability areconsidered; the categories of electrical receivers, as well as factors, providing the sustainability andreliability of compressor station, are defined. In the last section of this chapter the volumes of powerconsumption at compressor station and auxiliary power plant are considered.The second chapter provides a classification of wind turbines, their design and wind flowcharacteristics, as well as the methods for wind climatic characteristics determination at a giventerritory. Particular attention is paid to offshore wind turbines as the most promising wind energyinstallations.The third chapter presents environmental aspects of wind power industry: an impact on fauna, acousticnoise, vibration impact, radio waves interference, air pollution, land use, visual impact, tourism andrecreation zones.The fourth chapter represents the consideration of wind turbine exploitation, including thedevelopment of a wind energy project, the power generation base cost definition, as well as the ways toreduce the costs of power generation and prospects of development and usage of wind power industryin the Russian Federation.
