UPS (Uninterruptible Power System) is an energy storage device, and it is also a uninterruptible power supply which contains the inverter as the main component and works at the constant voltage constant frequency. it is playing an increasingly important role. Some suggestions are mainly proposed to ensure the safety of UPS power supply system in this paper, which make the UPS power supply system really play the role of escort in the practical application.

Chapter 7 follows the role of the grid in the emergence of partition as the preferred solution to the Palestine question. The deliberations over partition re-actualized the question of borders, dormant since the period of intense negotiation in the early 1920s. Again, the power supply system figured prominently in the deliberations. At this point, the network of power stations and electrical wire crisscrossing the land provided a thick materialization of the Zionist vision. This material reality was reflected in British deliberations and carried over into the U.N. Resolution 181 for the partition of Palestine, adopted by the General Assembly in November 1947. The same considerations played out on the battlefield, as the resolution triggered the 1948 War, from which the state of Israel and the statelessness of the Palestinians emerged in May 1948.

The urban railway systems using state-of-the-art technologies for train traffic, safety, traction and rail infrastructure are becoming increasingly widespread in the world. The Moscow Central Circle railroad is an example illustrating their integration into the urban transportation system of a megacity.Development and continuous modernization of such railroad systems during their operation generate new innovative approaches, particularly in the field of electric power supply.Electric traction load on the traction electric power supply system of the Moscow Central Circle railroad has several features explained by prevalence of passenger traffic and frequent changes of operating modes of electric trains. Frequently used regenerative braking determines the statement of the problem of developing a complex of measures to increase the efficiency of traction power supply system measured by the criterion of output capacitance reduction and of energy efficiency indicators’ growth. The use of electric energy storage systems within the traction power supply system can help to solve thementioned problem.The objective of the described research is to assess the efficiency of the implementation of the electric energy storage devices within the system of traction power supply system of the Moscow Central Circle. The research uses the methods of statistical processing of the measurement data and of simulation modelling. Simulation modelling of interaction of electric rolling stock with traction power supply system within the Moscow Central Circle allows to obtain the characteristics of load chart of electric energy storage systems and of bus voltage at sectioning posts, to evaluate the durations of operation cycles in charge and discharge modes, their number and relevant total amount of electric energy per day.The obtained results allow assessing the technical features of various types of electric energy storage devices regarding operating conditions within traction power supply system of the Moscow Central Circle and to determine the economic efficiency of their implementation.

Currently, energy generation industry transition to a new technological platform based on smart electrical energy systems (EES) is underway, with EES equipped with active-adaptive mains. This platform involves a large-scale use of digital devices and significant electrical energy (EE) generation using distributed generation (DG) plants which are to be created by power consumers. These plants can operate as parts of existing grids, or be pooled in network clusters. To implement smart EES, the development of new approaches is required for production, distribution and EE consumption modes management. The article is dedicated to the issues of DG plants application to raise efficiency of non-traction consumers power supply systems. In this case, a special attention was paid to enhancing the electrical energy quality via application of the DG plant which is controlled by concordantly set generator automatic voltage regulator (AVR) and automatic speed governor (ASG). For optimization and harmonization of AVR and ASG settings a method of nonparametric identification of the ‘turbine-generator’ system was used which can be represented as complex activation functions of main channels and crosslinks of regulators and the generator. The study was carried out in Matlab environment on a created railroad power supply system model. The studies conducted helped to detect that application of DG plants with concordantly set AVR and ASG makes it possible to enhance power quality for non-traction consumers and ensure dynamic stability and resilience of railroad line power supply system.
