OPEN SOFTWARE ARCHITECTURE FOR DISTRIBUTED HYDRO-METEOROLOGICAL AND HYDROPOWER DATA ACQUISITION, SIMULATION AND DESIGN SUPPORT

In order to provide support to management of complex hydropower systems and their digital simulations it is necessary to establish communication between measurement systems and computational models, although they were not primarily designed on the concepts of mutual integration and possible reusability. This paper presents one of the possible solutions for distributed hydro-meteorological and hydropower data acquisition, simulation and design support that is based on service-oriented architecture (SOA) principles. The complex and heterogeneous information flow used by these systems is portioned into separate data and computational functions that use common open protocols for mutual communication. Based on the Web Services techniques, the paper presents the principals that can help design many business-independent services and deploy them depending on computational power and data distribution. The Web Services technology can not only reduce the complexity of applied software and improve its reusability, but it can also implement dynamic application integration in order to decrease the costs of system development and maintenance.
