Abstract The test bed is intended for investigations of autonomous current supply system and its individual units and testing of the correspondence of the system to the demands of the wind power alternator with high-temperature superconductive field winding. The test bed configuration is based on module principles thus accelerating the adapting of experimental equipment for quite definite tasks. The test bed contains serial equipment and a number of units specially developed for the definite test program. Some of specially developed modules are presented in the paper.

Corrosive Effect

To permit the use of high-vanadium residual oil as fuel for combined super-charged-boiler gas-turbine power plants, it is necessary to determine the treatment required to prevent the high-temperature corrosion and deposit problems associated with this fuel. A test program has been undertaken wherein a number of magnesium and aluminum-bearing additives have been injected into washed residual oil when firing a laboratory-scale, simulated supercharged boiler. Different tube arrangements within the boiler have been tried. Ash collected on the tubes at various locations has been analyzed and its corrosive effect at high temperatures on some types of stainless steel has been evaluated. The results thus far obtained are presented together with some hypotheses regarding the formation of deposits.

Main Factor

The overall dimensions and mass of wind power units with capacities larger than 10 MW can be improved and their cost can be decreased by developing and constructing superconducting synchronous generators. The article analyzes foreign conceptual designs of superconducting synchronous generators based on different principles: with the use of high- and low-temperature superconductivity, fully superconducting or only with a superconducting excitation system, and with the use of different materials (MgB2, Bi2223, YBCO). A high cost of superconducting materials is the main factor impeding commercial application of superconducting generators. In view of the state of the art in the technology for manufacturing superconductors and their cost, a conclusion is drawn, according to which a synchronous gearless superconducting wind generator with a capacity of 10 MW with the field winding made of a high-temperature superconducting material (MgB2, Bi-2223 or YBCO) with the «ferromagnetic stator — ferromagnetic rotor» topology, with the stator diameter equal to 7—9 m, and with the number of poles equal to 32—40 has prospects for its practical use in the nearest future.

This paper discusses the problem of measuring unsteady pressure in a high-temperature environment using standard transducers. Commercially available cooling adapters for these transducers use water as the cooling medium to provide thermal protection. This arrangement is suitable only for some test bed applications and not suitable for integration into in-flight active control systems. An assessment of the cooling effectiveness of a commercial water-cooled adapter using air as the cooling medium is presented using an experimentally validated finite element heat transfer model. The assessment indicates survival of an air-cooled transducer, itself rated to 235°C, at source flow temperatures up to 800°C.
