REVERSE OSMOSIS PLANT POWERED BY PV HYBRID SYSTEMS IN HOTEL SECTOR BY USING EUROPEAN INSTALLATION (EIB)

摘要

The aim of this paper is to present the study of a reverse osmosis plant powered by a hybrid system that consists of PVs, fuel cells and battery inverter. The work was partially supported by the European Commission, under the Research Directorate General, Non-Nuclear Energy Programme, CRAFT-JOULE JOE3-CT98-7018 "Development of an Energy Management System for Hotels using standard sensor/actuator components and the European Installation Bus". The study is concerned with the creation of a model, which can be used in the hotel sector. The flexibility and modularity of EIB technology and the availability of compatible component by a growing number of large manufacturers are some of its major assets. In a hybrid modular system, electricity generators, such as PV, wind turbines, small hydro, and storage units are coupled on the established single or three-phase AC grid. Compatibility of components is achieved by using EIB standard interfaces. The advantages of this solution are high reliability, simple expandability as well as simple installation, use and maintenance. The application of such energy management systems seems viable for stand-alone and grid connected energy supply systems for one house/user or small communities. The energy supplying units and loads are simply connected to the AC energy grid, as well as to communication bus (twisted pair or power line couplers) via standard EIB interface components. The EIB technology provides the convenience to control and assign tasks to the various components, defining the energy management strategy and the supervision and safety functions. A case study for the installation of a reverse osmosis plant powered by hybrid systems in hotel sector by using European Installation Bus (EIB) is examined in an island hotel in Greece.
