The paper deals with the design of the state district power station, the prototype of which is the Pechora state district power station. Based on the territorial location, climatic conditions, the main power electrical equipment is selected. The GIS scheme is also selected. Based on the results of calculations of short-circuit currents, switching devices, live parts and measuring devices were selected for metering and monitoring the quality of electricity. Thus, GIS YaEG-220 was chosen as the switchgear. The choice is due to the following advantages: high operational reliability, compactness, reliability of the insulating medium. The work includes the calculation of the profitability of the construction of the «Pechora-Ukhta» power transmission line. The optimal current has been found, at which the highest profitability indicators are achieved. It was found that in order to achieve optimal payback, it is necessary to introduce additional measures, such as: reactive power compensation, measures to reduce the corona, lower income tax, redistribution of consumer loads, the introduction of penalties for unused declared power, an increase in consumption during the night failure of the daily load schedule, reduction in income tax. The last chapter presents the choice of an automated system for commercial metering of electricity. This system meets all modern requirements. The need to update the system is due to an increase in the power output of the power plant, as well as to upgrade the equipment. |
