DETERMINING THE ECONOMIC EQUIVALENT OF REACTIVE POWER AND MECHANISMS OF ITS APPLICATION IN THE PAYMENT OF TRANSMISSION REACTIVE POWER

The current system in Ukraine pay for reactive power flow in electrical networks energy-transmission enterprises in the industrial and non-industrial consumers based on technical and economic compensation costs due to loss of active energy. The basis of payment laid the economic equivalent of reactive power. However, the system used to pay salaries of functional dependence the economic equivalent of reactive power the economic equivalent of reactive power not reflect the actual losses of active power, making calculations fees opaque. Since in this case the regulation in the sphere of natural monopolies, the board must determine exactly compensate energy-transmission enterprises and accurately determine their income for services rendered by reactive power. The article deals with the issue of accuracy evaluation of active power losses from reactive power. The mathematical models and algorithms for determining payment for reactive power flow based on piecewise linear approximation using the proportional distribution of losses among consumers. Calculation of the economic equivalent of reactive power proposed to implement depending on the active consumer loads and boundary values of reactive power for a given voltage class networks. Allowance of losses arising due to their non-linearity of power consumption and their cumulative increase in excess of the limit values of the coefficient of reactive power by many consumers.
