During the last decade wind-power engineering is intensively developing in a number of countries. Total capacity of wind-electrical installations (WEIs) all over the world reaches 50 GW, including about 20 GW only in Germany. In a number of countries new industry of power-mechanical engineering is created, it is wind-power mechanical engineering. This industry ensures the mentioned rapid growth of wind-power engineering. World market of wind-power engineering equipment was formed.

In foreign countries the basic method of WEI application is their parallel operation with power network. A block-diagram of network WEIs is shown in fig. 8.6. Such technology allows dampening the capacity change of wind-power installations in the power system, connected with wind speed variation, and complete using of energy, generated by these installations. However, at growth of WEI capacity share higher than by 10…15 %, the power system could lose its sustainability.

 The most progressive technology of wind power application in Russia, at least nowadays and in the nearest future, is use of WEIs for autonomous power supply of consumers in the distant areas. However, owing to wind variability and its complete absence, capacity of WEIs changes or goes down to zero, that it is unacceptable for consumer. Therefore, application of WEIs requires using either electrical accumulators, or joint operation with power installation at any traditional energy carrier.

For larger autonomous consumers it is reasonable to apply power complexes, including WEIs and, for example, a diesel power installation.

The most urgent task is creation and application of such autonomous power complexes, including WEIs.

 Among renewables being intensively developed, wind power sector takes the leading position. In 2013 total capacity of all of the renewables (except all hydro) achieved 560 GWe, including wind power plants making 318 GWe (or 57 % of all renewables without hydro). In 2012 capacity of wind power plants constituted 283 GWe, i.е. during one year an increase by 12 % was achieved. In this article technological aspects and information on equipment for wind power plants are presented. It is done with sectioning the article into grid connected, autonomous and hybrid plants as of 2013. In this article the materials from the first version of section 8 “Renewables” of Information Electronic Constantly Updated Open System “The Best Available and Perspective Nature Protection Technologies in the Russian Power Industry” of the Moscow Power Engineering Institute (http://osi.ecopower.ru), prepared by JSC ENIN and actual materials have been used.
