CONTROL OF VOLTAGE MODES AS A MEANS OF LOAD REGULATION

Abstract

The article substantiates the regulation of power consumption modes of production facilities due to the management of voltage modes in the power supply system. It is shown that the regulation of electricity consumption with the help of consumers - regulators (CR) is quite often associated with losses that occur when the CR is turned off. Studies have shown that the management of voltage modes in the power supply system, which affects its level, can play a positive role in increasing the efficiency of the optimization of power consumption modes. It is shown that a comprehensive solution to the problem of power consumption management is expedient both at the expense of CR control and the influence on the voltage regimes of the power supply system. It is shown that the regulating effect of the load is characterized by static characteristics. Solving the problem of forming static characteristics is possible in two ways: through active experiments and based on the integration of static characteristics of individual consumers. Experimental studies were conducted to identify the static characteristics of the load. Experiments were carried out on transformers of the main step-down substation of the chemical industry enterprise, equipped with on-load tap-changers. Experimental static characteristics with linear changes are constructed. The parameters of the model are determined by the method of least squares. Constructed experimental and analytical static characteristics. The voltage mode control procedure for load regulation is implemented in the power consumption control system.
