Abstract

Purpose. Development of the method for matching of the input and output voltage ranges of the pulse DC voltage converter, as part of the electrical equipment of the wind power plant with a variable speed of rotation of the wind turbine shaft.
Methods. Graphoanalytical calculation methods, which are also a means of the results visualization for determinate the parameters of the pulse DC voltage converter was offered.
Results. The graph interpretation of the «guaranteed controllability» area, «non-unlocking» area, and «non-locking» area with the help of the grapho-analytical method of matching of the input and output voltage ranges of the pulse dc voltage converter are defined. The first area corresponds to the operation modes of the pulse dc voltage converter, for which a stable operation of the wind turbine with a variable rotation speed of the wind turbine shaft is provided. The second and third areas correspond to the emergency operating modes of the power plant.
Originality. The graphoanalytical interpretation of the converter voltage variation ranges as part of the electromechanical system of the wind power plant, which allows to visually presenting the problem of matching of the operation modes of the wind power plant equipment is offered.
Practical value. The order of matching the ranges of input and output voltages of the pulse DC voltage converter in the structure of the electrical equipment for wind power plant with variable rotation speed of the wind turbine shaft, which allowing to determinate the zone of guaranteed controllability of the wind power plant is proposed
