Reliability analysis of distribution systems has been attracting increasing attention. A special concern pertains to the distribution networks on which most failures occurs. The optimization of distribution system of breakers and power switches is a possible strategy to improve reliability. The paper describes development procedure for modelling restoring after a fault and calculating associated reliability indices and customers’ outage costs. The developed model of the network and reliability and outage costs calculating algorithm is suitable for multi-criteria analysis of the network. Proposed reliability and outage costs calculation algorithm is based on Monte Carlo simulation and genetic algorithm.

The interaction of real and virtual devices is an important point in the design and development of control system. The central part of an embedded control system is a controller and it needs input devices and output sensors for realization of the control. The proposed approach allows using a real controller with its specific programming tools and languages for intelligent software development and virtual measurement and sensor devices realized in a computer environment. Different wireless compounds are necessary for intelligent embedded devices for transport system control. For this reason a wireless communication network is needed to ensure the data transmission between the controller and supervisory control and data acquisition system. The purpose of this paper is to propose an approach for interaction of real, embedded and virtual devices in electric transport control systems. The main tasks are: to analyze objects and functional dependencies of an electric transportation control system, to develop a control algorithm with the interaction of real and virtual devices, to ensure a wireless connection for the data transfer from the controller to the supervisory control and data acquisition system, to define the method of transmitted data processing. Computer and practical experiments, with real and embedded devices, and the results analysis will be described the paper.
