The reliability of stand-by power supply of consumers in Crimea peninsula during peak demands periods and in emergency situations was increased. Start of power station in the absence of voltage in power grid is possible only in case of power supply from stand-by power source with succeeding transition to the baseload power source. Earlier it was necessary to stop the plant. In result time and service life expenditures increased. To increase the reliability and efficiency of generating equipment specialists of Mobile GTES developed technical solutions with using of units of automatic synchronization for auxiliary power plants. During the tests conducted by Chernomorskoye RDU operational capability of new equipment was checked. At present 18 mobile gas turbine power plants are in operation in the region. Their total output is 405 MW. They provide third part of power demands of the region.
