Development of hardware and software simulation tools for 4 type wind turbine modeling

The purpose of the paper is a hybrid simulation of 4 type wind power plants, which allows to obtain a fairly complete and reliable information about the processes taking part in the wind power plants of the specified type, as well as to evaluate the effect from their implementation in power systems as a whole. Today renewable energy is developing rapidly in the world mainly due to the use of wind power plants. To solve most of the problems of study, design and operation of wind power plants as the components of the electric power system we need complete and reliable information about the single continuous spectrum of normal and abnormal quasi-established and transient processes in the equipment under investigation and in the electric power system as a whole. Mathematical modeling becomes the only way of obtaining such information since full-scale experiments are inadmissible in real electric power systems (especially emergency ones) and physical modeling of such systems has significant limitations. At the same time, there is a certain problem of obtaining reliable information via mathematical modeling due to the need to solve rigid systems of large order differential equations describing the processes in the elements of wind power plants and electric power systems as a whole. This problem is characteristic of all software, computing and hardware-software systems designed for calculating modes and processes in electric power systems. They inevitably use numerical integration methods as a result the reliability of such calculations is low or unsatisfactory. The article describes an alternative integrated approach to 4 type wind turbine modeling. This approach is implemented by means of the developed specialized hybrid processor of type 4 wind power plants, which is designed to operate as a part of the All-mode real-time modeling complex of electric power systems. The article provides the fragments of test studies of the produced specialized hybrid processor that confirm its correct operation. The solution of the problem of adequate modeling of 4 type wind turbines proposed in the article is new and relevant (as applied to the certain electric power system, its composition and topology) and allows to obtain sufficiently reliable, all-mode information on the processes occurring in it for further planning of modes, setting of automatic control systems, relay protection, automation, etc.
