Abstract: The direct GPS signals are successfully used in navigation and positioning application. However, reflected GPS signals can also be viewed as useful source for remote sensing information. In this paper, the system parameters that affect the system performance are presented. These parameters include coherent time, footprint area, SNR, range rms error, and number of coherent pulses. Three different scenarios for GPS bistatic measuring are proposed in this paper based on the altitude of GPS bistatic receiver. The comparison among system parameters are discussed in the three scenarios.

Keywords: Global Positioning System, Remote sensing, range rms error, Signal noise ratio, bistatic altimetry.

Abstract: Continuity in the development of the human race ultimately needs sources of renewable or virtually inexhaustible energy such as wind renewable energy resource. The history of wind energy describes a general evolution from the utilization of simple, light equipment’s driven by aerodynamic drag forces; to heavy, material-intensive drag equipment’s; to a rise in the utilization of light, material-efficient aerodynamic lift equipment’s in the modern period. Wind energy is essentially looked at in the area of public policy, economics and managerial perspectives. Due to the increasing penetration of wind energy in the transmission system modern wind turbines are required to take over the control tasks, which were traditionally aligned to conventional power plants, and to contribute to power system stability. The most promising wind turbine concepts for the future market are investigated in the presented work, namely the doubly-fed induction generator wind turbine (DFIG) and the direct driven wind turbine using a permanent magnet excited synchronous generator (PMSG) connected via a full-scale converter.

Keywords: energy, light equipment’s, utilization, full-scale converter.

Abstract: The article explains the concept of mobile substation direct current auxiliary power system (DCAPS) design, ensuring resistance to high altitude electromagnetic pulse (HEMP), with due account for the features of the mobile substation. The measures improving mobile substation survivability under such impact are presented. The article is the sequel to an earlier article [1] related to the measures aimed to improve the survivability of stationary substations.

Keywords: Power Substation, Electromagnetic Pulse, HEMP, Direct Current Auxiliary Power System.

Abstract: High Altitude Electromagnetic Pulse (HEMP) is a challenging agent aimed to destroy the most critical types of electric equipment in the most important components of national infrastructure. The article examines the measures to keep the substation direct current auxiliary power system (DCAPS) running upon HEMP, and describes the method to effectively protect the DCAPS operating equipment, using special elements and redundant power supplies based on diesel generators and compact DC power supplies.

Abstract: Water scarcity is one of the major problems facing major cities of the world and wastage during transmission has been identified as a major culprit, this is one of the motivations for this research, to deploy computing techniques in creating a barrier to wastage in order to not only provide more financial gains and energy saving, but also help the environment and water cycle which in turn ensures that we save water for our future. We presented our research in embedding a control system into an automatic water pump controller through the use of different technologies in its design, development, and implementation.
