The use of fuzzy sets considering the operation of biogas plants under the conditions of voltage unbalance

Abstract

A feature of problem solving of energy security in Russia at present time is environmentally friendly energy production. Numerous research works of the quality of electric energy reveal a significant discrepancy with the permissible standards. This will require not only an increase in the contribution of various energy sources to the overall energy balance, but also a more careful approach to the electric power quality. A significant part of the raw materials of agro-industrial facilities is used to generate electricity with an efficiency coefficient of 31%. Performance of electric power varies from 48 to 104 kWh per ton of feedstock, as a rule, organic waste. Disfunction of conversion units is accompanied by significant harm. The high harmonic of current and voltage adversely affect the operation of current-using equipment, electronic devices, distance control elements, relay protection, automatic equipment operation and protection tripping units.
