FIELD: power industry.
SUBSTANCE: this invention relates to an operating method of a wind-driven power plant under ice formation conditions, to a wind-driven power plant and to a wind power farm with multiple wind-driven power plants. The operating method of wind-driven power plant (1) with nacelle (2) with an electric generator and aerodynamic rotor (3) connected to the generator and having one or more rotary blades (4) involves stages of operation of wind-driven power plant (1) if deposition of ice on rotary blades (4) can be excluded in a reliable manner, and shutdown of wind-driven power plant (1) if ice deposition is detected on rotary blades (4), and shutdown or prevention of repeated start with time delay of wind-driven power plant (1) if ice deposition is not detected but it is to be expected, and/or permission of repeated start with time delay of wind-driven power plant (1) if the shutdown condition, which led to shutdown of wind-driven power plant (1), is eliminated again, and ice deposition was not detected, and ice deposition or formation of ice deposition is not to be expected.
EFFECT: invention is aimed at improvement of detection of ice deposition on rotary blades of wind-driven power plants.
