Abstract
Introduction of devices for simultaneous adaptation to operational conditions of power systems is a topical issue in scientific research. Controlled switching - CS presents the basic vision in the introduction of various devices. We would like to carry out research into the advantages of CS on simulation models with the application of FACTS devices which improve the loadability of power networks. With respect to CS we would like to present the operation of POCON and BES devices in distribution networks. This devices enable the injection of real power, voltage control and active filtering. The global trend of development in power electronics is important also for the resolvement of undesired phenomena at switching maneuvers causeing network stability problems and hazardous overloadings of apparatus and devices. FACTS devices are an important field in the activities of the program group. Attention primarily focuses on increasing loading capacity of the currently operating networks, improving transient stability of the system in case of network faults, and on the research into providing the power quality. Electromagnetic radiation and strict rules in the world show that there could be serious sanctions in the over 1kV voltage level network. Scheduling operations in manufacturing has been an attractive area of research in Computer Integrated Manufacturing (CIM). The primary goal of scheduling operations is finding the best way to manage manufacturing resources to effectively and timely execute required production plans. A key problem in JSP is coping with the number of possible schedules that grows exponentially with the problem size. Even for the most sophisticated methods, large scale problems such as 30 machines and 150 jobs remain computationally very expensive to solve. All parts of research are an important field for Slovenia where we can expect a relatively fast implementation of the said devices in applications. As mentioned in the previous item, the importance of the said devices in the world, our research group hopes that our power utilities and other big or small electricity consumers will recognise the advantages and possibilities enabling quality design of power network systems and devices as well as quality supply of electricity. At the same time these devices will enable smaller voltage and current overloadings and a minimum harmonic pollution in a network. The question of electromagnetic field reduction in Slovenia is becoming increasingly more important. Electromagnetic management will be one of the main subjects in the field of electromagnetic compatibility. We are working intensively in this direction and wish to expand our research in the future. In the field of industrial electronics we have developed a robust, low cost and light weight current level monitor for overhead transmission lines. The product seems to be a feasible solution providing a low cost line-failure detection for many existing installations. For new installations better and more expensive solutions may be appropriate. The unit can be mounted over a transmission line during normal operating conditions and due to its light weight there are no additional requirements regarding the line mechanical load.
