【 摘 要 】

The use of energy saving technologies, reduction of losses of electric power and the electric power are actual tasks of modern power industry. The cheapest and at the same time the most effective means of increasing the technical and economic indicators of electrical systems is reactive power compensation. The paper considers three variants of reactive power compensation: installation of high-voltage capacitor banks; installation of low-voltage capacitor banks); overexcitation of synchronous machines. The comparative analysis was conducted on models compiled in the program MATLAB Simulink. The costs of generation and transmission reactive power using synchronous motors were defined. The costs of generation and transmission reactive power using low-voltage capacitor banks were defined.
