Transformer design is a challenging engineering task, where the different physical fields have to be harmonized together to fulfill the implied specifications. Due to the difficulty of this task, it can be separated into several subproblems. The first subproblem, in the pre-concept phase, during the transformer design is the calculation of the cost optimal key-design parameters, where not only the technical but also the economical parameters have to be considered, as well. This subproblem belongs to the most general branch of the non-linear mathematical optimization problems. This paper presents the main directions of the evolution and trends in the power transformer design. Main directions of the considered research and the future trends in the field of preliminary design transformer optimization methods are summarized.

“…The collaboration between Budapest University of Technology (Hungary), Ben Gurion University (Israel), and IPHT Jena (Germany) has demonstrated a test bed of a 12-kVA synchronous generator machine group protected by a HTS FCL device [45]. The research is related to a scheme of a HTS "Mini Power Plant" (generator, transformer, SMES, flywheel, motor, FCL) rated to about 10 kVA which the group intends to construct and test in the near future.…”

Superconducting devices tend to operate in one of three general regimes. Applications which are based on the zero resistance of the superconducting state, those based on the transition between the superconducting and normal state, and those based on Josephson junctions. When speaking about energy applications the main interest is focused on the first and second regime. Electrical power applications have been a challenge for high-temperature superconductor (HTS) materials since their discovery. Today, however, the only power application that has been commercialized is superconducting magnetic energy storage (SMES) and all those units are based on NbTi technology at 4.2 K. Success of HTS devices in energy sector depends on developing materials to techno-economic maturity and organizing efficient production, making model tests of key components and proving reliability in endurance tests. In general superconducting power applications offer a number of benefits to the electrical system: increased energy efficiency, reduced equipment size, reduced emissions and flexible transmission and distribution. This paper reviews the current status of superconducting power technology in Europe where some consortia have been established. SCENET Power (The European Network for Power Applications of Superconductivity) is formed by working groups of a small number of laboratories collaborating in pilot projects and CONECTUS is the Consortium of European Companies Determined to useSuperconductivity.

“…A whole superconducting plant can be introduced into the power system rather than individual SPDs. 12 The concept of an AS HTS substation is presently becoming an available solution of power applications of superconductivity. 2 Based on the achieved technological results in the field of the applications of superconductivity, 12-14 the concept of an ASPC, and, in particular, that of an AS mini power plant (MPP) model in the power rating range of 10 kW has been developed by the author's team.…”

The widespread use of energy-efficient, environmental-friendly and secure local power stations, or mini power plants (MPPs) has become a world-wide trend. Disperse power generation has been developed against centralized generation in central power stations/plants with a particular view on the utilization of renewable energy sources. Exceeding the stage of the development of individual superconducting power devices (SPDs), more and more concern is being focused around all superconducting (AS) integrated systems (ASIS) consisting of a set of individual SPDs being integrated into one system with a common cryogenic environment. Such a system possesses with substantial additional benefits compared to and exceeding those of the individual SPDs. The concept of AS MPP model of the order of 10 kW developed by the author's team is presented in this paper.
