Oscillations in hydropower bulb units

Abstract: The paper presents the results of studying the specific problems that occurred during the exploitation of two 42 MVA bulb generators. The work focuses particularly on two groups of problems which were more pronounced on only one of the two hydropower units, and these are increased vibrations of the hydropower unit and electromechanical oscillations in the stationary and transition states, which significantly depend on the operating point of the drive. This paper shows a part of extensive generator measurements. A lot of probes were mounted on the generator measuring all electrical and mechanical physical quantities, as well as air gap width, induction in air-gap and others.

The effect of implementing of dynamic cross saturation on modeling of synchronous generator

Abstract: The aim of this paper is to explore the effect of implementing of dynamic cross saturation in modeling of synchronous generator. The mathematical model of a saturated salient pole synchronous generator is developed and two cases are analyzed. In the first case the cross-magnetizing phenomenon in the saturated synchronous machine (the magnetic coupling between its direct and quadrature axis) is included, while in the second case the cross-saturation is neglected.

Private accommodation in tourist destination offer - the case of Dubrovnik

Abstract: For a long time basic accommodation capacities represented the dominant type of accommodation in tourist offer, while at the same time complementary accommodation capacities were neglected. However, recently there has been a growing interest for complementary, substitute types of tourist accommodation, both in the Republic of Croatia and in Dubrovnik, where since 2000 a significant increase of over night stays has been registered, especially in private accommodation. In this paper rooms, apartments, studio apartments and holiday houses owned by physical entities are referred to as private accommodation.Private accommodation enables tourists to engage in everyday life of local residents, learn about history, tradition and culture of a destination. Thus, a tourist may experience and taste the beauties and attractions of a place, truly enjoy autochthonous products and services, as well as obtain genuine knowledge on authentic attractions and tourist offer of a destination.Inadequate offer of private tourist accommodation has negative influence when forming the overall tourist offer of a destination. Poor quality of accommodation units, unprofessional conduct of holders of tourist accommodation offer towards consumers and lack of interest for the needs and wishes of the consumer of this complementary accommodation have all contributed in creating a bad image on this kind of accommodation in tourist offer. Consequently, this paper aims, by analyzing the consumers of private tourist accommodation, to point out the importance of private accommodation in overall tourist offer of a destination, to prove that private accommodation tourist offer attracts an increasing number of tourists, and propose to local tourist administration directives on how to create a more efficient procedure in order to ensure a more efficient and better quality administration of tourist private accommodation offer, aiming to improve the overall tourist offer at a destination.
