Since data sharing mechanism between the various business systems lacks of specification and standardization, information shares hardly and data exchange are inefficient, the paper proposes a data exchange platform for power enterprise based on ESB, which is based on SOA architecture, unified data exchange standards by using XML, used SOAP/HTTP(S) as the data transfer protocol between business systems and services bus and used Web Services as the business system data exchange standard interface. BEA ALSB service bus provides data exchange services for registration, release, information, routing and other functions. Practice has proved that the platform has good flexibility and scalability and can meet the business enterprise system between all kinds of complex data exchange requirements.

The paper describes a new MLF (Mostly Loaded First) method of HTTP requests scheduling and distribution in a cluster-based Web system. Its application enables keeping the quality of the Web service on the required level and makes the Web service behave in a predictable way, opposite to other Web services offering unpredictable and unreliable services of best-effort type. MLF method helps to keep the page response time within established bounds, so that at a heavy workload, servicing both small and simple or more complex pages, would not exceed the imposed time limit. In the method presented, appropriate mechanisms of HTTP requests scheduling have been applied, as well as a new algorithm of the requests distribution has been proposed. In the paper, the method, the testbed and results obtained, which indicate desirability of further research on the MLF method, are presented.

The paper presents the range and possibilities of using expert systems at diagnostic measurements of insulation systems of power appliances taken by the acoustic emission (AE) method. Multi-parametric descriptors characterizing the AE signals, which can be used in the knowledge base as criteria making the identification of basic partial discharge forms (PDs) possible, have been characterized in detail. The paper shows descriptors describing the AE signals registered in time, frequency, time-frequency domains and statistical data.

The paper presents the idea of using and application of On-Line Analytical Processing (OLAP) systems in monitoring of electrical power engineering devices. Data saved in central repository for historical data are submitted through online working analytic systems. At the moment of addition of new data happens process of definition the mutual correlation between the new and already existing data. This leads to the analysis based on OLAP systems. The hereby paper describes the advantages of OLAP systems in aspect of using them in monitoring of electrical power engineering devices.

The paper presents the performance of the switched reluctance motor. The calculation of the magnetic field and electromagnetic torque were performed using the Femm program, based on the finite element method. The calculation results are in good agreement with experimented data obtained on the prototype motor. The presented calculations enables to determine the output electromechanical parameters of the motor already being in the stage of the design.
