Synchronization of self-contained power supply systems in solid mineral mining in the Arctic Shelf

In the conditions of the Arctic Shelf development, the key problem is the remoteness of mineral deposits from the existing and operating power supply systems. This dictates the use of the totally self-contained power supply systems with the energy sources independent of regular and expensive fuel supply. Effective operation under conditions of harsh climate necessitates employment of up-to-date power electronic converters. High-performance DC-to-DC converters allow maximum electric energy supply from photovoltaic power plants while DC-to-AC converter-based voltage inverters ensure the required parameters of output current. Creation of power supply systems and power supply without failures needs integration and parallel operation of a number of power sources such as diesel electric-power generators and renewable power plants. Such plants and their parallel operation require overall and instantaneous synchronization of frequency, voltage and phase. The present analysis of operation of photovoltaic power plants used statistical data on power generation, and modeling and optimization of connection diagrams of converters involved classical methods of network calculations: loop method and nodal method, which made it possible to anatomize operation of the converters and to enhance efficiency of the whole power network.
